I totally agree that the enhance D.O.F. of small format digitals is a boon in macro photography. It opens up whole new creative possibilities. But, for every door that opens another closes - the ability to employ a narrow DOF in portraits, for instance, is not present. I've tried creating Bokeh in photoshop, but I could never get one that looked realistic. Possibly my limited PS skills, though.
One problem with small format digitals and macros, though, is that it is very hard to get higher magnification macros. I use a digital with an 8 - 24mm zoom. Close up lenses designed for 35mm don't work, nor does reverse mounting a lens on the camera, for the simple reason that the focal length of the digital is so small. And if you could put the lens on enough extension for more magnification (impossible with a built in zoom, but for the sake of discussion...) the working distance of a lens with such small focal length would be nil. The DOF is a big boon in shots that are the equivalent of shots up to 1:1 in 35mm format, but so far I haven't been able to figure out how to go higher. - MCC At 05:51 PM 12/8/01 +0100, you wrote: >I see some more opportunities for small CCD cameras.
