And for those who want to relive the thrilling days of the '60s, the D80 can make multiple exposures -- three in one image, anyway, with the ability to automatically compensate exposures for the multiple.Power options: The EN-EL3e battery has a huge CIPA battery rating of 2,700 shots per charge, which can be increased with the MB-D80 battery grip ($150, street), which can take two EN-EL3e's or six AAs and adds a vertical shutter release. The fuel-gauge battery condition gauge is a great idea, but we wish it weren't two levels down in the menu.
Flash system: For those familiar with the D70's wireless Commander Mode and its limitations, the D80 is a welcome upgrade. The built-in flash can now control compatible Speedlights (SB-800, SB-600 and SB-R20) in any of four channels, and can operate two groups, which allows you to set different output levels on individual flashes. Moreover, the built-in unit can fire in a multiflash setup (and operate essentially as a separate group). The D70 limited the built-in flash to triggering only in Commander Mode.
Postproduction: There's lots of fun to be had with the D80 after you take a shot. In the camera, you can convert an image to monochrome, with conventional black-and-white tonality, sepia tone, or cyanotype blue tone. You can add a skylight effect or a warming filter to color shots. You can combine two RAW images into a multiple image, with adjustments to the relative opacity of the image.
