You’d think the Image menu might have something to do with making changes to an image document as a whole, wouldn’t you? In practice, some of the entries you’ll find here do apply to the whole document, but others apply only to particular layers or selections.
For example, the Mode menu item allows you to change an entire image from grayscale to color. The Duplicate, Image Size, Canvas Size, Rotate Canvas, Crop, and Trim selections all change the whole document in some way. (Their functions are obvious from their names, except for Trim, which removes pixels from the edge of an image.)
A new command on the Image menu is Pixel Aspect Ratio. This command allows you to view your image in common digital video aspect ratios that aren’t square (such as 16:9), thereby simulating the display of the image on a device that uses non-square pixels, such as a movie screen or a wide-screen TV.
On the other hand, the changes wrought from the Adjustments submenu can’t be applied to an entire image if the document has more than one layer. Adjustments such as Color Balance, Hue/Saturation, or Brightness/Contrast work only with a single layer or a selection on that layer.
You’ll find yourself turning to the Image menu more often than many of the other menus, partially because it’s so useful, and partially because, for some reason, many of the options don’t have keyboard shortcuts that let you bypass the menu. By the way, Adobe removed the Histogram option from the Image menu in favor of its own palette.
