For our Lightroom customers, similar camera support can also be found in Lightroom 2.1 currently available on Adobe Labs as a Release Candidate.

Lightroom 2.1 Available on Adobe Labs

A release candidate of Lightroom 2.1 is now available on Adobe Labs.  The ‘release candidate’ label indicates that this release is well tested but would benefit from additional community testing to validate the corrections and changes included in this update. The Lightroom team would like the community to help verify the quality of Lightroom 2.1 through normal usage as this will ensure that the application is tested on a diversity of hardware and software configurations not available internally at Adobe.
The goal of this release is to address bugs that were introduced with the release of Lightroom 2.0 and provide additional camera raw support. A comprehensive list of issues fixed in this release is provided on Adobe Labs. If you experience any issues with this release please report them on our User to User forums or through the bug report form.
The Lightroom team would like to thank all of the photographers on the Lightroom User to User forum who helped provide constructive insight into the issues that we have fixed in this release.
The camera support added in this release is identical to the support provided in the recent Camera Raw 4.6 update:

  • Fuji Finepix IS Pro
  • Nikon D700
  • Nikon D90
  • Nikon Coolpix P6000

See my blog post for additional details on preliminary raw support for newer camera models.

Camera Raw 4.6 and DNG Converter available on Adobe Labs

The Camera Raw 4.6 and DNG Converter Release Candidates (RC) are now available on Adobe Labs. The ‘release candidate’ label indicates that the plug-in is well tested but would benefit from additional community testing before it is distributed automatically to all of our customers. The Camera Raw team would like the community to help verify the quality of the plug-in through normal usage as this will ensure that the plug-in is tested on a diversity of hardware and software configurations not available internally at Adobe.

This release includes official camera support for the following cameras:

  • Fuji Finepix IS Pro
  • Nikon D700
  • Nikon D90
  • Nikon Coolpix P6000

Please provide feedback on your experience with the Camera Raw 4.6 plug-in and the DNG Converter on the Camera Raw User to User forum.

Camera Raw provided ‘unofficial’ support for the Nikon D700 raw format in Camera Raw 4.5.(And Lightroom 2.0)   That support has been certified without requiring any changes to the previous implementation.  Camera Raw is often able to provide unofficial or preliminary support for new camera raw formats.  While this support is not fully tested and certified by our Quality Engineering team it does allow photographers who have acquired more recent camera models to open and work with their raw files.  In Camera Raw 4.6, photographers with the following cameras will be able to utilize this preliminary support:  Canon Rebel XS, Canon 50D, Olympus SP-565 UZ, Sony A900 and Sigma DP1.  (Sigma DP1 support is not finalized due to an unresolved white balance bug that will require additional testing)

Lightroom 64-bit on XP x64

Several photographers have asked about running Lightroom 2 as a 64-bit application on Windows XP x64. Lightroom will not install as a 64-bit application on Windows XP by default because it’s not an officially supported platform for our 64-bit version.(Lightroom is officially supported on Vista x64)   But when you run the Lightroom installer and choose to "Open the Specified Folder" in the Files are Ready dialog (Be sure to uncheck the option to "Launch the Adobe Photoshop Lightroom 2.0 Installer")  you’ll see an Adobe Photoshop Lightroom directory that contains "setup32" and "setup64" executables.  I’ll let you pick the one you think most appropriate.  

InstallDialog.jpg

Again, just to be clear, running Lightroom 2 as a 64-bit application on Windows XP x64 is not a supported configuration.  The testing required to certify an additional operating system is a significant effort but there was not enough evidence to suggest that we should completely disable the configuration. 

Why all the excitement about a 64-bit version of Lightroom?  64-bit capable operating systems and applications can take advantage of more memory than 32-bit systems.  If you have a 64-bit environment with more than 4GB of RAM you’re most likely to see improvement in the responsiveness of the Develop module where Lightroom is loading large amounts of information into memory. (A common misconception is that 64-bit systems will see an improvment in import or export performance. Those operations are largely disk-bound so they’re dependent on the speed of your hard drive for performance improvements.)

Plug-in or External Editor?

There has been quite a bit of discussion around the concept of plug-ins for Lightroom. When photographers think of plug-ins it typically brings to mind very unique or specific filters designed to adjust the appearance of an image. Photoshop has a rich history of supporting these image processing plug-ins. The extensibility of Lightroom is different in that we’ve been focused on workflow extensibility that allows developers and photographers to extend the application as a workflow platform that connects to third party services, allows for custom web galleries or custom metadata to adapt to a photographer’s workflow. Photographers would still like to see image processing plug-ins in Lightroom and I agree with them. But for a plug-in to actually behave like a plug-in it can’t break the non-destructive workflow. There has been a little flurry of discussion around the Aperture 2.1 image processing “plug-in” API and the subsequent utilities released behave less like a plug-in and almost exactly like the external editor functionality that has been available since Lightroom 1.0. If a plug-in requires that a derivative TIFF or PSD file be created and block access to prior non-destructive adjustments it’s not really plugged into the application is it? 

However, if external editors are what you need, we’ve got them.  In Lightroom 2 we’ve added the ability to define as many external editors as you want. And you don’t have to wait for software manufactures to create a custom “plug-in” for Lightroom, just utilize the existing standalone application like the one available for Noise Ninja. The optimal implementation of an external edit interface at this point is the use of a smart object workflow with Photoshop CS3. I’ve used it many times with PTLens and I really appreciate the fact that I can go back and adjust raw settings after I’ve applied the PTLens correction.(Then revisit the PTLens settings) This is an incredibly powerful link between the raw and rendered workflow and half measures with marketing spin labeled as “plug-ins” are not the highest priority for the Lightroom team.

New in Lightroom 2.0

Some abbreviated notes to get you started

Library

Streamlined Organization and Worfklow

Layout: The entire Library layout has been revisited to provide a more intuitive image organization experience.  The left hand panel of the Library has been streamlined to include only the most relevant image sources: the folders the images are physically stored in and collections of images that the photographer creates. 

 

Folders:  Photographers working across multiple hard drives will find that the enhanced volume and folder layout will make it a much more intuitive experience to manage images on one or many hard drives.  The volume indicators clearly indicate the hard drive that you’re working with and provide the option to show the online/offline status, the amount of space available, the number of photos you’re working with and there’s an indicator light that migrates from green to red as your hard drive fills up.  Now it’s visually much easier to move your images from hard drive to hard drive and understand where your images are stored when a external hard drive is no longer connected.

 

Collections: The Collection panel has received significant attention with the addition of improved iconography and collection sets that allow photographers to create a hierarchy while maintaining collection-specific sort order. There is also the ability to save output specific collections for Slideshow/Print/Web.  This can be accomplished by creating a new collection item while in the specific output module.  The subsequent icon in the collection panel will provide a quick reference and link to the images and output settings you created.  Collections still maintain their auto-save capabilities when it comes to on-the-fly output creations that don’t require a persistent entry in the Library. 

 

Smart Collections are now available.  Specify the criteria for a smart collection and images will be automatically added to the collection if they meet the criteria. An expert user tip: Try alt/option clicking when adding a new search criterion. 

 

Target Collection functionality allows you to specify any Lightroom collection as the destination of the quick collection shortcut key, B.

 

Filter Bar:  With the source location of the images clearly defined in the left hand panel, the top of the grid view provides a panel that will filter the content.  Use the ‘\’ key to hide or show the filter functionality and expand one section at a time to filter the content.  Each category below can be toggled on or off by clicking on the name and multiple filter categories can be shift-selected to provide additional control.

Text: Search across your images using text search field

Refine: Filter your grid view by flags, star ratings, color labels and the type of file, Master or Virtual Copy.  This functionality was previously located only in the right hand side of the filmstrip.  It still remains in that location now labeled ‘Filter’ as a quick tool that can be used in any module.

Metadata: A wide range of metadata is now presented in easy to browse filter columns that can be added, removed and customized per your organization workflow.  Choose the field to filter on by clicking on the column header and select menu icon at the right side of each column to add or remove a column.   The column arrangement and selection can be stored as a preset that is defined in the upper right hand corner of the filter bar.  Note that the Date and Location fields contain the option to show hierarchical or flat representations of the data.  The Date field also includes the day of the week in addition to the numerical date.

 

The Keywording pane has a new Keyword Set called “Suggested Keywords.” Keywording is simplified through Lightroom’s ability to suggest keywords for the current image based on existing keywords applied to that image as well as keywords applied to images that are close neighbors in terms of capture time.  For example, if a number of images in a catalog contain the keywords dog and beach, an image assigned the keyword ‘beach’ will cause the suggested keyword panel to automatically update to show ‘dog’ as a suggested keyword. The Keywording panel also includes a dedicated keyword entry field below the larger box that displays all of the assigned keywords. The Keyword List provides a convenient filter to help find and manage your keywords.  Checkboxes are available to quickly apply additional keywords to the selected images and arrows to the right of each keyword are a link to view all of the images tagged with that keyword.

 

Multiple Monitors: Lightroom 2.0 offers a dual monitor solution that can adjust to fit your particular monitor set up.   The main Lightroom window that includes the Module picker can be positioned on either monitor and the following views can be provided on an additional monitor. To activate a multiple monitor environment, choose the monitor icon in the lower right hand side of Lightroom, just above the filmstrip.  If a second monitor is not attached, a second window will appear on a single display.

  • Grid: Place the grid on a secondary monitor for quick image selection while the develop module is displayed on the other monitor.  Or use the grid to reorder images while creating slideshow, print or web output.
  • Loupe:  Allows an image at a preferred zoom level display on an alternate monitor. 
    • In Normal mode, the image displayed on the alternate monitor is changed when the selection is changed in the primary Lightroom window.
    • Live mode is continually updated based on the image and area of an image the mouse is currently hovering or passing over.  Zooming to a 1:1 view allows for quick focus checking across a number of images displayed in a grid view on the primary monitor.
    • Locked mode fixes the image displayed on the alternate monitor until you wish to change the selection by selecting alt/option-Enter to make the current selection visible.
  • Compare: Offers the same powerful compare functionality previously in the Library but can now be used to compare images while selections are made in the grid view in the Library or while adjustments are made in the Develop module.
  • Survey:  View multiple images at once while organizing or adjusting in another display.

 

Photoshop Integration:  Lightroom can now open images directly in Photoshop without writing out TIFF or PSD files first. The previous ‘write file to disk first’ behavior was inefficient and the new behavior enables a faster a more functional workflow that includes:

  • Open files in Photoshop as a Smart Object: Utilize the non-destructive smart object workflow by opening the image as a smart object directly into a Photoshop document.
  • Select multiple images to merge as a Panorama utilizing Photoshop CS3’s incredible new panorama functionality
  • Merge multiple exposures into a single Photoshop HDR image
  • Load multiple files or virtual copies into Photoshop as separate layers in a single document.
  • Important Note:  This integration is only available with Photoshop CS3 (10.0.1)

 

Export Functionality: Managing and organizing exported images is much easier now with the following capabilities:

  • Export files automatically to the same folder as the original or a subfolder of the original
  • Add the exported images to the Lightroom catalog with the option of stacking the export file with the original
  • Sharpen images on export for Print or Screen usage utilizing an adaptive algorithm that takes into account the intended use and resolution.
  • Send exported images directly to another third party application selected in the export dialog

 

More notes on Library functionality:

  • The 10k pixel limit has been lifted and now images with up to 65,000 pixels per side or 512MP total may be imported into Lightroom.  This is particularly useful when utilizing the new Photoshop integration for panorama creation.

 

Develop Module

Localized Correction: The develop module now provides the ability to correct specific areas of an image without affecting other areas.  A common example of this in traditional photography would be the dodge and burn experience in the darkroom.  Lightroom provides brushes that a photographer can ‘load’ with different types of corrective techniques that were previously only available globally including exposure, brightness, clarity and saturation.  Images can also be tinted locally using specific hue and saturation values that can provide an excellent way of counteracting mixed lighting environments.

The tools previously available in the toolbar have been relocated to the right hand panel just below the histogram. (Crop, Clone/Heal, Red Eye and the new local correction brush)  Selecting a tool from the panel will reveal the options for that tool.  Click on it again to hide those options and return to the standard develop panel.

Adjustment Brush

The controls available for the local correction brush are segmented into three basic areas: Mask, Effect and Brush.  A quick walkthrough of the correction technique is below:

  • On entering the local correction panel the brush will become active. 
  • The type of desired correction should be selected from the Effect section.  A photographer can paint in a positive brightness effect for the shadows and a negative exposure effect for a bright sky.
  • Combinations of effects can be selected and saved as presets by showing the effects sliders. (Horizontal toggle in the upper right area of the effect panel)
  • The brush size, feather and opacity can be set before applying the correction.  An Auto Mask option is available to help confine the brush strokes and subsequent mask within an area of similar color.  The airbrush option provides a diffused correction application relative to the standard painting mode. 
  • Once a brush stroke is applied, a circular point or pin will appear on the image where you first applied the brush stroke.  Additional brush strokes can be applied that will add to the current correction area. To refine the area hold down the Alt or Option key to begin erasing with the brush.
  • To adjust the amount applied to the entire area click down on the circular marker or pin and move the cursor to the left or the right to decrease or increase the amount setting.
  • To refine the correction settings, click on the pin and detailed adjustments are available in the right panel and will be applied to the selected pin. 
  • Create a new correction mask or brush stroke by selecting the New option.
  • The pins can be hidden or shown with the H shortcut key.
  • Use one of the tint presets provided to apply a color tint or use the Lightroom color selection dialog by double-clicking on the rectangle to the right of the presets.  Change a preset by selecting a color in the dialog then click-and-hold on the preset box to be populated by that selection.
  • There are two brush presets represented by A and B in the brush section.  After modification of the brush controls, a preset can be updated by clicking and holding on the specific preset letter to be associated with the settings.

Graduated Filter

Recreating the effect of a graduated neutral density filter, this tool goes even further allowing the ability to modify all of the effect parameters in a single graduated effect.  Select the effect and click and drag the gradient onto the image.  Rotate and adjust as necessary.  You can also return to the specific effect settings and modify them after the filter is applied.

 

Shortcut Keys

Vignette: The previous lens correction vignette effect was only applied to the entire image frame and as an artistic effect could be obscured after an image was cropped.  An additional framing vignette effect has been added that will apply a vignette to an image, respecting the cropped borders.

 

Basic Panel Keyboard Shortcuts:  Photographers who prefer to utilize their keyboards for basic image adjustments will find that the +/- keys are linked to the Exposure adjustment in the Develop module.  Adding the Shift key will boost the increment amount, the comma and period keys will cycle through the basic panel controls and the semi-colon will reset the control currently in focus.

 

Improved Auto Adjustment:  The Auto adjustment has been modified in response to feedback that previous adjustments were too bright.

 

Improved profiles for Raw data:  An enhanced set of profiles has been released on Adobe Labs in order to provide an improved default rendering of raw data. (Many Canon photographers complained that our reds were too orange.)  In addition to the improved Adobe default profile, there are additional profiles for each camera that emulate the results that would be obtained were those settings chosen in the camera manufacturers software or if the photographer chose to shoot JPEG.

 

Print Module

Picture Package: The print module now provides the ability to create multii-page layouts for a single image arranged in multiple sizes. This allows photographers to quickly and easily print a package of images quickly and easily. 

  • Choose Picture Package from the Layout Engine in the top right corner of the print module and a blank page will be presented.
  • In the Cells panel click on one of the preset size to add an image cell to the page or use the drop down option to edit and create your own custom size.  Cells can be added to the page until the page is filled and a new page will be added to the layout automatically.  Up to six pages can be included in a layout. 
  • After all of the required cells have been added, choose Auto Layout to automatically create an efficient, easy to cut print layout or manually move the cells to your liking.
  • To move a cell, click on the image and move the cell to the desired location.  To delete an image cell, click on the image and choose delete.  A page can be deleted by mousing over the page and clicking on the ‘X’ in the red circle.
  • When an image aspect ration is much different than the cell aspect ratio, the image can be moved within the cell by holding the CMD/CTRL key down and clicking on the image and dragging it.

Print to JPEG:  Many photographers have asked for the ability to send their Lightroom print layouts directly to a lab that will print JPEG files.  Choose JPEG as the option in the Print Job dialog to specify your print output as a JPEG file for lab delivery. (Select a custom ICC profile for your lab in the color management area)

Print Sharpening:  Lightroom previously provided three levels of print sharpening.  Impressive new algorithms have been added to automatically determine the correct amount of print sharpening required based on the output media and resolution of the file.

 

Lightroom 2 SDK

The Lightroom SDK allows you to customize and extend certain Lightroom features by creating plug-ins. In the current release these features are extensible:

 

Export functionality: You can create an export plug-in, which customizes the behavior of Lightroom’s Export dialog and export processing. You can add or remove items from the Export dialog, alter or augment the rendering process, and send images to locations other than files on the local computer.

 

Metadata: You can define customized public or private metadata fields for Lightroom. Public or private metadata can be associated with individual photos.

 

Web engine functionality: You can create an HTML web-engine plug-in, which defines a new type of HTML photo gallery. The engines you define appear in the Gallery panel at the upper right of the Web module.

 

A Lightroom plug-in consists of Lua-language files (scripts) that define the plug-in functionality, and an information or manifest file that describes the contents of the plug-in. The information file must have a specific name, and be placed in a folder with the Lua source files and resource files; the folders may need to be in specific locations.

Changes from LR2 beta to LR2 below:

  • Hierarchical Dates and locations in the Library Filter. (Including days of the week for the date)
  • The Volume Browser in the folder panel. 
  • Improved iconography for folders, collections, collection sets and output collections.
  • Dedicated keyword input field in the keywording pane.

Last but not least, don’t forget to enjoy Rule Number 5!

Camera Raw 4.5 and DNG Converter available on Adobe Labs

The Camera Raw 4.5 and DNG Converter Release Candidates (RC) are now available on Adobe Labs. The ‘release candidate’ label indicates that the plug-in is well tested but would benefit from additional community testing before it is distributed automatically to all of our customers. The Camera Raw team would like the community to help verify the quality of the plug-in through normal usage as this will ensure that the plug-in is tested on a diversity of hardware and software configurations not available internally at Adobe.

This release includes new camera support for the Olympus E 420 and E 520 camera models.

Please provide feedback on your experience with the Camera Raw 4.5 plug-in and the DNG Converter on the Camera Raw User to User forum

For Lightroom customers who would like to use the new support provided for the Olympus cameras, download the DNG Converter release candidate and convert your raw files to DNG before importing them into Lightroom 1.4.1.

DNG Specification and Vista DNG Codec

The DNG Specification has been revised and the version number incremented from 1.1.0.0 to 1.2.0.0. This is not an area of frequent change given that the format has done a good job of addressing the progress of raw formats over the last three years.(The last update was finalized in February of 2005)  This update addresses several industry requirements for the DNG format including the formalization of the concept of a “camera profile” and a metadata tag to validate your image data. 
The definition of a camera profile for the DNG format as well as the allowance for multiple camera profiles to be embedded in a single DNG file will provide the industry with the ability to characterize raw data in an efficient and standardized format.(Think ICC profiles but for raw data)  
Additional metadata tags have been defined for the DNG format including a field to indicate a ‘hash’ or the integrity of the raw data within the file, providing a valuable tool for validating the safety of your image data.  A DNG file is comprised of three components: raw data from the sensor, metadata to describe the raw data and an embedded preview to represent your interpretation of the raw data. (See my earlier blog post on DNG if you need more background) Writing metadata back to a standardized file format like DNG is a common operation but many are concerned about the sanctity of the image data from the sensor.  The opportunity to ‘fingerprint’ that block of data and check it from time to time to ensure that there hasn’t been any disk corruption or I/O errors is a significant step forward in ensuring the archival safety of your images.  For the developer crowd, the DNG SDK has also been updated to reflect the changes to the specification.

The DNG Codec for Windows Vista users is also now available as a free download from Adobe Labs.   This is our first release for the Windows Codec platform and before finalizing the release we’re offering it as a ‘Release Candidate’ on Adobe Labs.  A release candidate is a version of the technology that is nearly complete but we would like the community’s help in ensuring compatibility across a wide variety of hardware and software configurations. 

On a final note, If you missed it earlier, you’ll want to check out John Nack’s blog post on the DNG format submission to the ISO.

Invite Some Friends

The Lightroom 2 beta has two expiration dates.  If you already own Lightroom it’s August 31st.  If you don’t own Lightroom it’s 30 days after you started testing the beta.(A 30 day trial)   I don’t think anyone disagrees that it’s important to reward the current owners for their purchase and use of the first version of Lightroom but we also don’t want to discourage new customers from providing feedback on the future of Lightroom.  To that end, we’ve provided current Lightroom customers with the opportunity to invite friends or folks they meet on the forums to enjoy the beta through the end of August.  Don’t be shy.  If someone has taken the time to provide feedback on the forums and wants to continue using the beta beyond 30 days, send them an invitation.  It’s a quick process and I’ve already sent many invitations myself. 
The invitation link is here: https://www.adobe.com/cfusion/entitlement/index.cfm?e=labs_lightroom_invite
Enter your Lightroom 1 serial number to authenticate the process and you’ll be able to send up to 5 invitations at a time. (The invitee will receive an email with a serial number for use with the beta)

Lightroom 1.4.1 and Camera Raw 4.4.1

The Lightroom 1.4.1 and Camera Raw 4.4.1 updates have been posted to the following locations: Lightroom(Mac, Win), Camera Raw(Mac, Win).  The updates provide all of the changes included in the original Lightroom 1.4 and Camera Raw 4.4 releases but also include corrections for issues described below and in previous blog posts.  The Camera Raw plug-in will also be available later this evening via the Adobe Update Manager and the Lightroom update can be located by choosing ‘Check for Updates…’ under the Help menu. 
The Lightroom and Camera Raw team apologize for any inconveniences caused by the issues presented in the initial updates

Lightroom

  • Lightroom 1.4 incorrectly modified the EXIF time date field of images that had a metadata update applied.  This incorrect modification does not appear in Lightroom or Bridge and is only viewable through third party EXIF tools.  This error has been corrected in Lightroom 1.4.1 and all files in a Lightroom catalog that have been incorrectly modified will be corrected on their next metadata update. (Metadata can be updated by selecting the files in the Library grid view and choosing Command or CTRL + S to save and update the metadata.)
  • Olympus JPEG files could render incorrectly in Lightroom 1.4, displaying an artifact in the exported file.
  • Any conversion to DNG in Lightroom 1.4 (Windows Only) would cause the DNG file to become unreadable by Lightroom’s Develop Module or Camera Raw 4.4 in Photoshop.  The issue has been corrected and files can be converted to DNG again in order to resolve the issue for existing files.  Returning to the original native raw files is not necessary.  The affected DNG files can be selected and converted again using the DNG Converter 4.4.1 available at www.adobe.com/dng/.  This process is not required but recommended to ensure that a correct validation value is stored within the DNG files.
  • Lightroom 1.4 provided degraded import performance relative to Lightroom 1.3.

Camera Raw

  • Camera Raw 4.4 incorrectly modified the EXIF time date field of images that were saved as TIFF or JPEG files from the Camera Raw dialog.  This has been corrected in Camera Raw 4.4.1
  • Olympus JPEG files could render incorrectly in Camera Raw 4.4, displaying an artifact in the exported file.
