How do I activate all of the image adjustments under "image" They used to be all activated and ready to use and now all of a sudden they are not shown in dark print. How do I get them up and ready to use?
Check your image mode. make sure your in RGB 8-bit per channel. Some features will not work in 16 or 32 bit per channel. Even though most feature will work in cmyk, I recommend setting it to rgb just to verify that it is working, then rule things out from there.
Adjustment work on layers. Photoshop also grays out menu items when the not available for son reason. Like only some adjustment work when your editing in 32Bit mode. Only some adjustment can be user on smart object layers. If your editing a normal raster layer in 8bit or 16bit mode I think all adjustment will work on that layer.
