Library Module and Workflow EnhancementsThere haven't been any UI changes in the Library module since beta 2, which means that the overall appearance should be familiar to anyone who already uses Lightroom 2 or has tried either of the two public betas. The Library continues to be at the heart of Lightroom in so far as it's the module that provides most of the tools for managing your photographic assets. Imported photos can be viewed in the Library in various modes or views. These include: Grid view (G), Loupe view (E), Compare view (C) and Survey view (N). Each of these views is intended for a specific purpose in the your workflow, but you may find one view more useful than others. For example, Grid view allows you see large numbers of photos as thumbnails whilst at the same time providing a workspace for applying metadata, labels, ratings, keywords, flags, and even quick development adjustments to photos in bulk. On the other hand, Loupe view allows you to view a single photo as well as zooming up to 11x of the original. This view is particularly use for checking sharpness and focus. The "gotcha" with Loupe view is that restricts rating, labelling, keywording, etc to a single photo. Compare and Survey are specialist views designed to make the tasks of comparing, rating and flagging multiple photos easier.
Figure 1 - Library module Grid viewOther minor, but nonetheless important enhancements within the Library module include:
Tethered CaptureAs mentioned above, there are relatively few major enhancements to the Library module since Lightroom 2. Nevertheless, those that have been included should please a lot of users. For example, Lightroom 3 includes support for Tethered Capture, albeit limited to a selection of DSLR cameras from Canon and Nikon. Support for other camera makes may come at a future date, but this is very much dependent on the vendor making their SDK available. Using Tethered Capture is relatively easy. First, you choose Library -> Tethered Capture. This opens the Tethered Capture Settings panel (shown in figure 2 below). The panel is used to configure the location for storing the captured photos, any metadata that wish to apply, etc.
Figure 2 - Tethered Capture SettingsWhen the settings panel is configured to your requirements, click the OK button. At this point the tethered capture control panel will open (shown in figure 3 below). Pressing the large silver button will trigger the camera shutter, as will pressing the Cmd/Ctrl+Shift+T keyboard combination. The Develop Settings pop-up menu is used to choose from any of the Camera Raw profiles already installed on your computer.
Figure 3 - Tethered Capture control panelThe control panel can be hidden by clicking on the circle button located below the Close (X) button on the right side of the panel. Alternatively, the panel can be hidden by pressing on the Cmd/Ctrl+T keys. Unfortunately, the control panel doesn't support remote adjustment of camera controls such as shutter speed, aperture or ISO; nor does it support the "Live View" feature found in many recent DSLRs. Video File SupportAnother commonly requested feature is support for DSLR Video Files. However, as with Tethered Capture the support for video files is rather limited. In short, you can import the video files, view the index frame as a thumbnail in Grid view or full-size in Loupe view (shown in figure 4 below), and export the files in their original format, but you cannot edit them or even review them in Lightroom, Instead,. to view a video file, you press the camera badge either on the thumbnail or loupe window to launch an external viewer such as QuickTime (Mac) or Windows Media Player (Windows). |

Automatic Corrections |
Manual Corrections |
When applied, the lens profiles are designed to automatically apply three types of correction. That is, geometric distortion such as Pin Cushion or Barrel distortion (see external material for more info), Lateral Chromatic Aberration, and Vignetting. When profile-based correction is activated (figure 16 - Automatic Corrections) Lightroom will use embedded Exif metadata for the lens and camera within the image to look for a matching lens profile. In the example shown in figure 17 below, the lens used was the Canon EF 16-35mm f2.8 USM. The three sliders located under the Amount heading are actually intended for fine-tuning the automatically profile correction. In the example shown in figure 17 you'll see that I have already reduced the amount of vignette correction to 75%. This is because the profile for this particular lens tends to over compensate for the lenses natural vignetting. Again, in this example I have already saved this correction as the new default for the lens, which means that my correction will be automatically applied each time the profile is activated. Occasionally, it may be necessary to increase one or more of the Amount sliders, although I have only found this to be necessary for chromatic aberration with one lens (i.e. Sigma 14mm f2.8). The Amount sliders can also be used to completely remove the respective correction. For example, you may want a lenses natural vignetting to be applied in full rather than corrected. Also, note that these sliders only become active when a lens profile is enabled.

Tip - you can only apply automatic lens corrections when the appropriate lens profile is physically installed on your computer. This is because the profiles are not stored in the actual raw file or XMP sidecar. Therefore, if you move your raw files between computers or share them with others it is important that you also install a copy the lens profile on these computers.
Creating your own lens profiles is a fairly straightforward, albeit time consuming process. Adobe have provided all of the necessary software and guidance documentation, so all you need is the time and the space to set up the calibration charts and camera.
Tip - I am making available a series of lens profiles, for various Canon EF lenses not yet available from Adobe. You can read more about the procedure for creating them and downloading copies for your own use here.
Manual Corrections
Switching to the manual corrections tab you'll see a mix of old and new adjustment sliders. The group of adjustment sliders listed under the Transform heading are new to Lightroom and operate independently of the automatic profile-based corrections. They're actually a mix of lens corrections, perspective corrections, and scaling. The geometric adjustment slider allows you to manually correct pin cushion or barrel distortion. The Vertical slider is used to apply a keystone correction to converging verticals (see figure 18 below for example). The Horizontal slider correct horizontal shifts, and is typically used to alter the horizontal viewpoint. Rotate is intended to be used to adjust the rotation of the transform, not the actual image. The final slider, is goes by the name Scale. This slider is used to adjust the scale of an image (i.e. zoom in or out). Typically, you will want to use it to remove the grey border after applying one of the other transforms. Enabling the Constrain Crop checkbox will automatically crop the image to remove any of the grey padding that appears after a transform gas been applied.
The remaining adjustment sliders operate much as they did in earlier versions of Lightroom. They've been retained for backward compatibility, but their presence may well lead to confusion, especially if the user subsequently applies automatic lens corrections from within the profile tab. Therefore, best policy is to avoid using them when a lens profile is available.
Applying the manual corrections to multiple images has also been taken care of with additional checkboxes being added to the Synchronise Settings dialog. As you can see from figure 19 below it's possible to apply all of the lens corrections or any combination of the four.

As discussed earlier, the biggest changes within the Develop module are associated with the new raw image processing, noise reduction and sharpening algorithms. On their own, colour noise and luminance noise are a substantial improvement over their predecessors, but together with the new capture sharpening algorithm they take image quality to a new level. Typically, details and textures are much cleaner, crisper and more natural. To see these new algorithms at there best I recommend that you make some prints.
Tip - it must be noted that these new demosaicing, noise and sharpening algorithms only apply when editing a process version 2010 photo

While the actual UI for the sharpening tool is the same as Lightroom 2 the actual sharpening algorithms have undergone significant change and improvement. The improvements begin with the new demosaicing algorithms, which are more noise resistant than in previous version. That is to say, the new algorithm does a much better job of removing color and pattern noise, but leaves much of the non-pattern noise behind. This residual random or grain-like noise is actually what gives the sense of detail and texture that many find appealing. The sharpening is achieved by adding halos to the edges in an image. Typically, one side of an edge will contain a dark halo and the other a light halo. In Lightroom 3 these halos have been made more subtle. For sharpen radius values between 0.5 and 1.0 the halos are much narrower than before, which means that it's now possible to sharpen fine-detail in landscapes more effectively. In a recent post to the Lightroom 3 User to User forum Jeff Schewe wrote:
"There have been some subtle but important improvements in the sharpening tools in Lightroom 3. The radius has been tuned so lower than 1 radii are more precise...the masking has been improved to have more cut-off in the masked areas while also allowing for local-sharpening adjustment brush additions to the mask, which means you can punch the sharpening a bit more and then paint away the sharpening in areas that get too crunchy. There have also been some technical improvements in the way the sharpened data is blended back into the unsharpened image data...
But the biggest impact on the sharpening has been the removal of noise reduction in the actual demosaicing and placing the enhanced noise reduction with additional controls later in the processing. Which this means is the sharpening by default now no longer needs to compensate for the built in noise reduction of the demosaicing, which could not be turned off.
The end result is while the sharpening has been improved the biggest thing you are seeing is the increased "bite" the new demosaicing allows."
For a comprehensive explanation on Lightroom 3 sharpening (and noise reduction) I recommend that you obtain a copy of Jeff Schewe's & Bruce Fraser's latest Camera Raw book - Real World Camera Raw with Photoshop CS5. While Lightroom 3 is not specifically discussed the details associated with sharpening and noise reduction are applicable equally to Camera Raw 6 and Lightroom 3.
Next we have noise reduction. With five sliders available you could be forgiven for being confused, not to worry Eric Chan provided the following description for each noise reduction sliders:
Luminance -
Luminance Detail -
Luminance Contrast
Color -
Color Detail
Figure 21 below shows a comparison between the old and new colour noise algorithms. The photos was shot on a Canon EOS5 Mk11 at 3200 ISO in quite poor lighting conditions. The color noise and sharpening are at default settings. Even allowing for JPG compression associated with the screen shots it should be pretty obvious that the new colour noise algorithms are vastly superior to the old. Figure 22 compares the same photo, but this time with a luminance noise adjustment of 25 applied. The left version uses default sharpening and the right has sharpening slider set to 50 and radius at 0.8

Adobe received quite a bit of feedback from photographers confused by the process version options in the first Lightroom 3 beta. So, in addition to new names, they made several improvements with the aim of ensuring that photographers can access the best raw processing quickly and easily. The improvements are summarised below:
The graphic to let you know that the current image selected in the Develop module is a previous process version has been enhanced and relocated to a more prominent position over the lower right corner of the image (shown on figure 18 above).
Clicking on the process version graphic provides additional details (shown on figure 23 below) about what will happen if you should chose to update to the current process version, the ability to see a before/after view of the old and new process versions and the ability to update all the selected images or all of the images in the filmstrip at the same.

For nearly as long as Lightroom has been around, now we finally we have it - an adjustable Point Curve. The parametric curve (i.e. original) operates as it always has, via sliders, by clicking on the curve and dragging up/down or using the Target Adjustment Tool (TAT). The advantage of this approach is that the adjustment of the curve is constrained to predefined limits, which have been optimised to prevent detrimental adjustments to the shadow, mid-tone and highlight regions. However, the in-built constraints occasionally prevent the user from making fine adjustments to specific parts of the tone curve. With the point curve very fine adjustments to specific parts of the curve are possible because you can set your own limits (lock points) and adjust the curve within them. Even greater control can obtained when you hold down the Alt/Option key while adjusting the curve. This flexibility, unlike the parametric curve, means that is possible to over adjust, thus causing some fairly extreme results. Some users may actually like what happens and use the point curve for creative effects.

Lightroom 3 beta 1 saw the removal of the button sets and Amount slider from the Local Adjustment panels . Since there was little, if any adverse feedback no further changes have been made to either the Graduate Filter or Adjustment Brush panels. Other enhancements to local adjustments include:
The Color palette is filled with a cross (X) to indicate that not colour has been selected for the brush or graduate.
The adjustment brush and graduate filter sliders can be reset by holding down Option/Alt and clicking on Effect (Reset)
Double click on adjustment name (e.g. Exposure) to reset individual sliders
Sharpness values between 0 and -50 will remove any capture sharpening applied via global sharpening. Values between -50 and -100 will blur the area you brush (similar effect to lens blur)
Additional brush strokes or gradients (stacking multiple pins) to strengthen the effect of the first

Post Crop Vignette
Post-crop vignette was introduced in Lightroom 2, but many users complained that the manner in which it was implemented did not properly reflect the desired effect. In particular, photographers wanted a tool that increased/decreased exposure/brightness rather than simply paining black or white into the image corners. Adobe thought they had addressed the earlier shortcomings in beta 1, but user feedback quickly dispelled this idea. Thankfully, they reinstated the original post-crop vignette style in beta 2. So, we now have three vignette styles, i.e. Highlight Priority (default), Colour Priority and Paint Overlay (original). Highlight priority is intended to produce vignettes similar to what you would get with lens vignetting. Colour Priority produces a similar effect, but is designed avoid hue shifts. Figures 26and 27 compare the first two styles with the same settings applied.

Figure 26 - Color Priority Post-crop Vignette
Other Develop module enhancements include:
Crop presets choices have been edited for clarity
A checkbox has been added to the toolbar to turn on/off overlay visibility
The targeted adjustment tool is deactivated when switching to a new Develop panel
Keyboard shortcut (X) to flip Crop Orientation
In the 2010 Process Version, the algorithms for Fill Light and Highlight Recovery have been changed to reduce the possibility of tone inversions (halos). You will likely need to fine tune the settings on these sliders after you upgrade the process version
New develop presets
Watermark Editor
The Watermark Editor (figure 27) first seen in beta 1 and underwent a fair amount of remodelling as the beta cycle progressed. With this new enhanced watermark editor you can apply a text or graphical watermark directly to a photograph. In addition to providing support for adjusting the size, orientation, location and opacity the watermark editor can also used to add creative effects such as a shadow. The watermark can be anchored in up to nine positions around the image or specific insets. The size of the watermark can be set proportionally or to fit or fill the photo dimensions. Saved watermarks can be applied from within the Slideshow, Print, Web and Export modules. In figure 28 I show a sample watermark applied to a photo in the Print module.
Figure 27 - Watermark Editor
Figure 28 - Watermarking a photo in Print module
Slideshow Module
In addition to JPEG and PDF Lightroom 3 can export slideshows as HD video. Another change is the link to the iTunes music library has been removed. This means that incorporating your music tracks doesn't require iTunes, but you can only use single tracks. Double clicking on the music track duration will automatically adjust the slide change time so that the slideshow duration matches the music. The Playback panel has also been enhanced to include new buttons for selecting the music and automatically adjusting the slide change time. A palette tile and checkbox has also been included to enable the user to add colour fades.

Other Slideshow module enhancements include:
Watermark editing included in Slideshow module
An option to prepare previews in advance will ensure that a slideshow is never interrupted waiting for image information to render to the display
Developers can now use ActionScript 3 galleries in the Web Module
Figure 30 - Export slideshow as HD video
Print Module
The next new feature I want to discuss is Custom Print Package. Like the Watermark Editor mentioned earlier the custom print package has been high up the request list from very early days. Laying out a page is relatively easy in so far as you can add Cells of various sizes using the button set located within the Cells panel. Once the cells are in place you can drag the images into them. Alternatively, you can create a free-form layout by dragging the images directly to a blank page then resizing them to taste. Figure 29 below shows fairly simple free-form layout containing 3 images of slightly differing size.
Figure 31 - Custom Print Package
Other minor, but nonetheless important enhancements to the Print module include:
Black or a custom color can be selected for a print layout background
The Identity Plate can be moved in small increments by selecting it and using the arrow keys
Match photo aspect ratio is now a persistent option in the Cell panel
Maximum print resolution increased to 720ppi
Rotate to Fit option and a Rotate Cell command were added to the custom print package layout tools
Web Module
Unlike the other four modules the Web module hasn't received much attention this cycle. That's not to say that there hasn't been any improvements, there have, but they are fairly minor and under the hood. The only really obvious enhancement to this module is the inclusion of the Watermark Editor. There are also some new Flash and HTML web templates.
