![]() ![]() I strongly suggest checking all the Missing Profile and Profile Mismatches checkboxes. I have my policy for RGB set to "Preserve Embedded Profiles". It's really a matter of personal preference. If you want to always work in the same color space within Photoshop you would select "Convert to Working RGB". If you work on other folks images you might prefer "Preserve Embedded Profiles" in the dropdown. Again, most photographers will be concerned with the RGB color management policy. The Color Management Policies section determines what Photoshop does when you open an image with a different color management profile than the one you are using for your working space. ![]() If you'll be working on raw files exported from Lightroom, then it would make sense to set your Photoshop working space profile to ProPhoto RGB since that is the color space Lightroom uses for editing raw files. Should you need to produce images for both prints and the web, set your working space profile to Adobe RGB and convert later to sRGB during your Photoshop workflow. The preferred color space for the web is sRGB. Adobe RGB has a wider color gamut (range of colors) than sRGB and works well with color spaces available on most inkjet printers. A recommended RGB working space profile for photographers is Adobe RGB (1998). Most photographers are mainly concerned with the RGB working space. Each of these color modes is assigned a working space profile. Adobe Photoshop has four working space modes: RGB, CMYK, Gray, and Spot. A working space profile sets the color gamut available to your image while working in Adobe Photoshop. To address your color settings click "Edit" from the menu (Application bar) then select "Color Settings". As noted above, layers and their layer mask can be saved with the image and re-adjusted at a later time. This allows you to selectively adjust specific areas of your image within the layer mask. When you select an adjustment from the Adjustment Panel, Photoshop creates an associated layer and layer mask for that adjustment. In fact layer masks are what makes layers so powerful. You can also change the opacity of a layer to make content partially transparent." You use layers to perform tasks such as compositing multiple images or to selectively apply corrections and filters via a layer mask. You move a layer to position the content on the layer, like sliding a sheet of acetate in a stack. You can see through transparent areas of a layer to the layers below. Per the Adobe Photoshop CS5 User PDF, "Photoshop layers are like sheets of stacked acetate. The last panel in the image to the right is the Layers panel which works in conjunction with the Adjustments panel. This is somewhat similar to using a layer mask, but offers less versatility/flexibility and the operations can't be saved and re-adjusted at a later time. This way you can selectively target corrections on your image instead of applying the correction to the whole image. In addition, the History panel along with the History Brush tool lets you paint in or paint out corrections you make. The History panel lets you undo and redo operations. Color corrections include Vibrance, Hue/Saturation, Color Balance, and Selective Color to name a few. Tonal corrections include Brightness/Contrast, Levels, Curves, and Exposure adjustments. Rather than edit image pixels directly, you can edit an adjustment layer and leave the underlying pixels unchanged. An adjustment layer holds color or tonal adjustments that affect the layers below it. Adjustment Layers can be saved with the image and re-adjusted at a later time. Without going into too much detail, applying corrections from the Adjustments panel creates an adjustment layer, which gives you more flexibility and doesn't discard image information. Once the panels appear on the workspace you can position them into a docked formation if you like. Make sure Options and Tools are also selected. Select Adjustments, History, and Layers in the menu dropdown. On a Windows workstation you can open these panels by clicking the "Window" menu item in the Application bar. This works out nicely since some of those panels are useful to photographers also. By default association these panels also have tabs for the Mask panel, the Histogram panel, and the Channels and Paths panel. Also note the three docked panels that I find most important in the image to the right: the Adjustments panel, the History panel, and the Layers panel. These may be referred to later in the document. Before we begin take a moment to quickly acknowledge the sections of the Photoshop workspace in the image above. ![]()
