More on Sharpening in Adobe Lightroom 3
In the theory of sharpening, the process can be broken down into three phases: capture sharpening, creative sharpening, and output sharpening. Last week I covered sharpening in the Develop module which is the primary tool for sharpening and can handle all three phases, but Lightroom also has dedicated tools for sharpening in the Import dialog of the Library module for capture sharpening, as well as in the Print and Web modules for output sharpening.
Sharpening During Import

Digital image capture is an inherently lossy process. Reality has to be forced to fit within the confines of your pixels and how they see the world. And since each photosite on your camera's sensor only sees one primary color rather than all three there is even more loss. Fully two-thirds of your eventual image has to be guessed, or "interpolated" based on data that was captured. If a given photosite is sensitive to red light, the green and blue values that will be used to render that pixel have to be approximated from neighboring pixels. The algorithms used to do this are quite sophisticated, but still involve a lot of guess work, even if these could be legitimately described as educated guesses. Capture sharpening aims to restore some of the softness caused by inherent limitations of this technology.
To get new images into the Library module in Lightroom, you have to import them. When you do, the dialog gives you the opportunity to apply a set of pre-saved Develop settings. These settings can include color correction, black and white conversion, adding film grain, vignetting, or just about anything you might want. If Lightroom doesn't come with a preset to do what you want you can save new presets. In my opinion, most of these sorts of edits are better made directly in the Develop module, but one type of change worth considering during import is sharpening. Specifically, I'm referring to capture sharpening.
Lightroom comes with two presets for sharpening: "Sharpening ? Narrow Edges (Scenics)" and "Sharpening ? Wide Edges (Faces)." In an unusual twist, these names are actually fairly descriptive. If you are importing a batch of images (such as scenics) that contains a lot of detail you want to render clearly, choose the former. If you have a batch of images (such as facial portraits) that should clearly show major edges but might yield unflattering results if every imperfection shows, choose the latter. If over time you don't find either of these to your liking tweak one or the other and save it as your own Develop preset.
Regardless of how you sharpen a batch of images during import, keep in mind that Lightroom never actually changes your actual image data. Whatever choices you make at this stage remain freely editable later on when you optimize each image in the Develop module. Think of sharpening during import as a time saver to get you in the ballpark. You're not locked into anything.
Sharpening in the Print and Web Modules
After you spend time making an image look its best in the Develop module, you have to print it or export it to some format that allows you to share it with others. Unfortunately, both of these are inherently lossy processes, just like image capture. There is a degree of softening that happens during printing or saving a file to jpeg or other similar formats. Output sharpening aims to mitigate this loss, and Lightroom helps you do this with tools provided in both the Print and Web modules.
Sharpening in the Print module takes a different approach from the way sharpening works in Develop. Gone are the sliders for such abstract variables as "Amount" and "Detail." In their place are settings for Media Type as "Glossy" or "Matte" and whether you want "Low," "Standard," or "High" sharpening. Together with the selected Print Resolution in pixels per inch, Lightroom can then use these choices to calculate the sharpening needed. Note that your choice of paper type here is independent from the paper type selection in your printer driver, but generally both should be set the same. If you select "Draft Mode Printing" print sharpening is disabled.
One thing that is missing from Print module sharpening is the ability to preview what you will end up with. It would be nice if Adobe provided a window to see how your choices will affect the results, but this would be difficult since so much depends on your particular printer and paper choices. You will need to figure out what works best for your own needs. One way to do this would be to put together a test file that represents the variety of what you normally print and print it with various choices. You can use one of the print package templates to easily print a selection of images at the same time. After printing, you can set the resulting pages side by side for comparison in detail.
Lightroom also lets you "print" to a jpeg file via the "Print To:" drop-down box at the top of the Print Job settings. Media Type isn't relevant in this case so Lightroom disables that selection.
Sharpening in the Web module is even simpler. Under Output Settings, all you get is a dropdown selection for "Low," "Standard," or "High." Lightroom handles the rest for you.
Keep in mind that you don't have to apply any sharpening in Print or Web. In fact, if you sharpen in the Develop module with your target output media in mind, you probably don't want to duplicate that in Print or Web. The choice of what you use is up to you.
The basics of panels are fairly straightforward. Individual panels are arranged into groups, one on the left and one on the right hand side of the screen. There's also the Module Picker across the top and the Filmstrip along the bottom. The display of each of these four main groupings can be turned on and off individually to provide more screen real estate for your actual image and what you are working on. To do so, go to Window >> Panels and check or uncheck the last four options for "Show Module Picker (F5)," "Show Filmstrip (F6)," "Show Left Modules Panel (F7)," or "Show Right Modules Panel (F8)" as desired. After you've done it this way a few times though, you will probably learn the keyboard shortcut equivalents for each. Press the F5 key and the Modules Picker will disappear. Press it again and it's back. The function key shortcuts for the others work the same way. Having one of these panels mysteriously disappear and not knowing how to get it back again is a problem experienced at some point by most new Lightroom users. Hit the wrong key on the keyboard in an application with this many keyboard shortcuts and there's no telling what might happen.
If you right-click on the header for an individual tool panel you'll get a context menu giving you the ability to completely remove each of the panels in that group (left or right) if you don't or rarely need specific tools. Simply uncheck a module and it will vanish, header and all. To get it back again, just turn on the checkmark next to it on this same context menu. There's also "Show All" and "Hide All" to do the same thing for everything in that group all at once. Yes, "Hide All" will indeed leave you with a completely empty but still visible panel group. The Navigator on the left will remain as will the Histogram on the right since they are controlled separately but everything else will be gone. Right-click on the gaping blank space that remains and you'll thankfully still get the same menu so you get your panels back. At the bottom of the same menu are options for "Expand All" and "Collapse All" to let you keep the panel headers but collapse all of their contents.
You can set the same automatic hide and show behavior with the top and bottom panels (the Module Picker and Filmstrip) using similar hide/show icon strips on the very top and bottom of the Lightroom application window.
First, as with all things in Lightroom, sharpening is processed non-destructively. It never actually changes the underlying pixels of your image. Everything it does exists solely as a list of instructions to be applied on-the-fly to your image preview. These instructions are stored along with all your other adjustments when you save your image. When you open it next time, everything is right where you left it. All your adjustments look like they are part of your image, but the really aren't. If you subsequently make more changes, nothing has been lost or degraded as a result of your earlier choices. You can tweak things as much as you want until you are satisfied, with no more loss than if you had made those same choices in the beginning. None of those edits actually get baked into your image until you print it or export it from Lightroom.



Go to Edit >> Preferences >> Interface. Not only can you change the shade of gray here that Lightroom will use as the fill color behind whatever is displayed in the main image area as well as the secondary display window, you can fill the area with a very fine pinstripe pattern. An odd touch to be sure, but I am unclear as to what use it actually serves. Indeed, if your monitor has a high enough resolution, the stripes that make up the pinstripe pattern are themselves barely perceptible with the result appearing nearly as just another shade of gray. Still, it's thoughtful of Adobe to provide a touch of class like this.
Since you've just looked at a selection of end marks you might have been expecting the folder to filled with the files used to render what youv'e just seen but the built-in end marks live elsewhere. But if you put your own file here you can indeed use it as an additional end mark choice.
To crop an image, open it in the Develop module and click on the Crop Overlay tool in the toolbar. In the standard window configuration, you'll find it as the far left icon in the first row underneath the histogram. Lightroom lets users reconfigure panels quite a bit so you may have moved things around in your copy. It looks like a dashed white rectangle. When you click on it, the image you are working on will be outlined with a thin white border with somewhat thicker adjustment handles on each corner and in the middle of each side. The area to be cropped is what is defined by this border so by default your entire image is selected. You can select a smaller area either by grabbing the adjustment handles and dragging them inward as needed, or by clicking with your mouse anywhere on the image and dragging to open up a new selection border replacing the current one. Either way, you can fine tune your crop selection until you are satisfied by means of the adjustment handles. You can also click and drag on the overlay with your mouse to reposition things, but rather than moving the selection border over the image, this will move the image itself underneath the stationary selection border. To me this seems somewhat counterintuitive as it requires you to drag to the right in order to reposition the selection border closer to the left hand side of the image and so on. You must drag in the opposite direction than it seems (at least to me) like you should since you are not moving what (at least to me) you think you will be moving. Remember, even though you must click inside the selection border to do this, the image moves, not the crop border.
You may be pleased to find that Lightroom provides a grid overlay on your crop area. This can help you recompose your image, aligning things with the rule of thirds or other preferred divisions of the frame such as the Golden Ratio made famous by the ancient Greeks and medieval painters. To change to the overlay, choose Tools >> Crop Guide Overlay from the menus. There's also a selection for Tool Overlay on the bar underneath the image when the Crop Overlay tool is active. Hitting the letter "o" on your keyboard will cycle through the overlays. You can turn the overlay off completely via Tools >> Tool Overlay >> Never Show. Curiously, hitting the "o" key will still cycle through even if set to Never Show. If you do, you will find your menu will change to "Always Show."
There's an apparent bug in the aspect ratio crop capability of Lightroom that you will at some point run into. While the Aspect ratio choice in the Crop Overlay options allows you to enter any ratio you want, there's no way to tell it to rotate that crop relative to the image. It always aligns the same direction the image does in terms of portrait versus landscape orientation. To elaborate, entering a custom crop aspect ratio of 3 x 10 will have the same effect as entering 10 x 3. Rather than one giving you a wider image and the other one a tall one, both will do the identical thing for any given image. Hopefully Adobe will fix this at some point.
