|Some filters are grayed out or are unavailable for the image I'm editing. What's the matter?||
Some filters are only available for images of 8-bits/channel or 16-bits/channel color depths and in specific color modes, such as CMYK. Adobe Camera Raw, 3D effects, Vanishing Point, and Filter Gallery options are examples of such effects.

|Blur Gallery, Liquify, or Oil Paint effects are unavailable or grayed out. How do I enable them?||
Some Photoshop features have special system requirements. For example, Liquify and Oil Paint require your computer to have a compatible graphics processor (GPU) installed. Also ensure that the Performance > Preferences > Use Graphics Processor setting is enabled in Photoshop.
Further, the performance of certain features benefits from enabling the OpenCL technology.
|When I try to perform an action, Photoshop prompts me that there's not enough memory (RAM). How do I resolve this issue?||Try adding scratch disks. Also, ensure that you have significantly more free disk space on your computer than the size of the document you're editing. Typically, you'd want 2X-3X free disk space when compared to the size of the document.|
|I tried to make an image sharper, but the text in the image is still blurred. How do I fix this issue?||Ensure that the image you're trying to sharpen has a resolution of 300 px or higher. You could also try using the Type > Anti-Alias command on the Type layers to sharpen them.|
|I can't find the Refine Edge tool in the latest version of Photoshop. Has it been replaced by a new tool?||The Select And Mask workspace replaces the Refine Edge dialog in earlier versions of Photoshop, offering the same functionality in a streamlined way. See Select And Mask | Tools at a glance.|
|I'm unable to open the Adobe Camera Raw filter while editing specific images.||
Adobe Camera Raw supports images of 8-bits/channel and 16-bits/channel color depths. Ensure that the image you're trying to edit meets this requirement.
