Display and menus contd...

The standard display in playback mode gives only minimal information (you can also turn all on-screen displays off and just view the images). Like most modern Canons the A640 has an orientation sensor, so can automatically rotate vertical images in playback mode. Pressing the DISP button allows you to pull up fairly comprehensive shooting information, including a histogram. A small but useful new touch is an overexposure warning [screenshot] which indicates areas with clipped highlights (in this histogram view only) using a flashing animation.
Pressing the 'up' key switches to 'JUMP' mode, with options to jump 10 or 100 images at a time, to jump to images by date shot or jump to movie files. Pushing the zoom lever to the left (wide) displays nine thumbnail images. A further push of the zoom lever to the left allows you to 'jump' from one page of thumbnails to the next.
You can zoom into (enlarge) saved images by repeatedly pushing the zoom lever to the right. The maximum enlargement is 10x. Incidentally, if you enable the instant review function and press SET whilst the image is displayed after shooting, you can magnify the picture just taken without going into playback mode. The play menu offers the usual range of options, including protecting, rotating and deleting images, plus slideshow's and sound memos.
As with most of Canon's latest models you can now apply My Colors effects to saved images in playback mode and save the result as a new file. This is much better than committing to the effect at the point of capture. Another change to the A620 - also common to all Canon's new cameras - is a separate Print menu.
The setup menu - accessible in both record and playback modes - offers control over various camera-related parameters, including audio, file numbering, date and time and card formatting. As is now standard on Canon PowerShots the My Camera menu lets you customize start-up image, and camera sounds.
