Setting Auto Action preferences
You can automate actions that must be performed in order to further edit an image.
For example, some commands can be performed only on images with a bit depth of at least 8 bits per pixel. When you choose a command for an image with a bit depth lower than 8 bits per pixel, the Auto Actions dialog box appears with the message that the image must be converted to a higher bit depth in order to proceed with the command.
