Importing Photos into Lightroom
If you're a Photoshop user just starting to use Lightroom, one of the first differences you'll run into is the fact that Lightroom is built around a database while Photoshop is not. In order to do anything with a photo in Lightroom, you first have to import it into a Lightroom catalog. It's here that your Lightroom workflow has to start.
Photoshop and Adobe Bridge can navigate to any folder on your computer as well as those accessible on your local network. If you can get at an image file through your operating system, you can open it in Photoshop and Bridge. Not so with Lightroom.
The architecture of Lightroom is built around the concept of "modules," with each module serving a different function. When you open the program, you can see them listed across the top of the screen as Library, Develop, Slideshow, Print and Web. It's from the Library module that you can import new photos. If you go into any other than Library, you'll find that the only images you have access to are those that have already been imported.
When you install Lightroom, it will create a catalog for you, but can create a new one if you feel a need to later by going to the File >> New Catalog dialog and giving your new catalog a name. There's also File >> Open Catalog if you have more than one and you need to switch between them. You can only have one catalog active at a time and switching forces you to close and reopen Lightroom, so most users simply put everything in a single catalog.
A brand new catalog is a rather uninteresting thing since it's just an empty container. You have to import images to it before you can do much. To begin the process, click in the "Import..." button in the lower left of the Library module, or use File >> Import Photos to get to the same place. You can also just drag a folder full of images onto the open Library window. Once you've already imported some images, you can also select "Import to this Folder..." from the right click context menu of any existing folder in the "Folders" section of the Library module. You can even tell Lightroom to automatically import your images by turning on File >> Auto Import >> Enable Auto Import. If you enable auto-import you'll want to also go to File >> Auto Import >> Auto Import Settings to specify which folder you want Lightroom to monitor and other default settings.

The basic Import dialog is straightforward enough with guided steps listed across the top. You can also click on the small downward arrow in the lower left to expand this small window to a full screen version. Both versions are basically the same, but the full screen window lets you see the individual images available for import so you can pick and choose, and also provides additional options. I'll talk mainly about the full window dialog here but either way, there are some basic steps necessary to import images. First, select a source, then select an action, and then a destination. When you choose the source, there's a checkbox to automatically include any subfolders. Above the previews in the full dialog you'll find a filter option to either see "All Images" or just "New Images." Obviously there will only be a difference between these two if you importing additional images from a folder you have previously imported from.
Importing an image into Lightroom doesn't necessarily make a copy of the original files. The dialog gives you a choice. "Add" keeps the photos in their original location and merely adds a reference to them to your Lightroom catalog. "Copy" leaves the original files alone, but makes a copy in the selected destination folder. "Move" copies your imported images to a folder you specify and deletes the originals. "Copy as DNG" is the same as "Copy" but converts your original camera raw files to Adobe's DNG raw format. With the action set to "Add" the destination automatically shows as "My Catalog." With another action selected you'll need to tell Lightroom where to copy or move the images you import. If you are importing directly from a USB attached camera your only choices will be Copy and Copy as DNG.
Which action you choose depends on how you want to manage your files. If you copy your image files to a directory structure where you want to store them before importing them into Lightroom, you should stick with "Add." If you want Lightroom to handle this for you, choose one of the other options. If you enable auto-import, you'll probably want to go with "Move" so the monitored folder gets cleared.
If you want to take a closer look at your source images before importing them, you can increase the preview size with the Thumbnails slider in the lower right. If that's not enough, you can also utilize the Loupe view using the icon in the lower left corner. By default, all images Lightroom finds in your source folder will be selected for import. If you decide you don't want to import any, just uncheck the box next to them.
That covers the basics, but before you actually begin the Import process, you should make sure a few other options are set the way you want them. You can tell Lightroom to look for duplicates and not import any that it determines you already have. The import process will consider files as duplicates if they have the same original filename, the same file size, and the same capture date and time in the EXIF metadata. If you are copying or moving, you'll be given the option to create a one-time backup of the imported files, a good idea just in case something unexpected happens. As a performance tradeoff, there are also options for telling Lightroom how it should render initial preview thumbnails. "Minimal" previews will immediately make use of the smallest camera preview present in each image and is generally a good choice. "Embedded and Sidecar" will use the largest available camera preview which will take longer but could result in a better preview. "Standard" tells Lightroom to immediately start rendering previews equivalent to what you would see in the Fit zoom level of the Loupe tool. "1:1" displays previews that are full sized images using actual image pixels. Preview jpegs embedded by cameras generally aren't color managed but should be sufficient in most cases. Regardless of your choice, Lightroom will start rendering standard previews via a background process. There's also robust support for renaming your imported images if you desire.
During Import, you can automatically apply a Develop setting preset. Since Lightroom is non-destructive, this will become merely the starting point for your future work in the Develop module. It doesn't actually alter your source images so if applying a preset during import gets you closer to where you ultimately want to end up, it can be a big time saver with no loss of quality in the final result. You can also apply a metadata preset to add copyright and other data you want to include in all of your imported images. I have a standard preset with copyright, contact information and so on. If all the images you are importing should share common keywords, you can add them during import as well.
When you've ready, click on the "Import" button in the lower right, or click on "Cancel" if you change your mind about importing. When you click on "Import," you'll start to see your images show up in the Library module as a progress bar moves its way along in the upper left. If you have a number of folders to import, you'll have to import them one at a time, or else organize them ahead of time so that all are under a single parent folder and use it as your Import dialog source. You can only have one Import task running at a time.

After you've spent some time setting all the Import options the way you want them, you can save these choices as a preset so you can more easily use them next time. Even the small Import dialog gives you access to select an Import options preset.
The Import dialog is incredibly flexible and feature rich. To fully master them, you might consider creating a "test" catalog and import images to it in a number of ways. After you've spent some time experimenting, you'll be in a better position to set up your real catalog and begin importing images to it.
The third slider for controlling Luminance noise is labeled Contrast. Since luminance noise is defined by varying brightness, excessive noise reduction can result in a slight loss of contrast. You can use this Contrast slider to restore it. Contrast restoration defaults to zero which is fine for most images. Generally, only very noisy photos require so much reduction that you need to worry about Contrast. 


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.
