Playback menus

One of the three alternative play mode views includes a histogram display and exposure information. You can also get this handy focus check display which zooms in on the focus point (the SET button switches from one focus point to the other in AiAF mode). You can also set this as an option for the instant review display in record mode.
Turning the control dial in playback mode allows you to scroll quickly through images (you scroll through full screen images using the left and right keys). The G10 provides play magnification up to to 10x. You can move around the image using the 4-way controller. Press the zoom controller towards the wide angle to switch to a 3x3 thumbnail index.
The G10 allows you to organize saved shots into 'categories', which you can assign to any image if you're the type who leaves hundreds of pictures on your card and needs to categorize them to make finding them easier. The dedicated jump feature menu remains from the G9, allowing the user to move from shot to shot based on various criteria.
You can apply 'My Colors' effects to saved images, which is much better than committing to them at the point you take the picture. The G10 retains Canon's fancy playback options, including slideshow transitions and a useful playback mode orientation sensor.
The play menu offers the usual range of options, including protecting, rotating and deleting images, plus a sound recorder. The G10 retains the seperate print menu from the G9, which allows you to select a 'range' of images and select by date when you want to direct print from the camera.
The G10 has a red-eye correction option in playback mode (it uses face detection technology so you don't need to find the eyes yourself). Finally the two-page setup menu, where basic camera settings (and card formatting) are accessed.
