I just got a call from a digital photographer we all know and who is one of the pioneers and chief practitioners of the craft. He related the awful tale that we hear all too often these days--that his computer crashed and all the data on his hard drive was gone. Luckily, he had been backing up all along, on CDs and a separate hard drive.

Note the "EX DG" appellation in this new Sigma lens. This signifies a lens that you can use for both film and digital photography, as opposed to Sigma's "EX DC" branding, which can only be used with digital SLRs. The difference is in the image circle each projects. Use a "DC" lens on a film camera and you'll have serious...

There are times when we have images that are too dark or too light and often
reject them out of hand. But the values only need to be adjusted to bring what
might have sat in shadow into the light. We can do that selectively with certain
tonal areas in the print or globally--that is, on the entire image. This

If you've ever been walking down the street and a picture caught your
eye, but had no camera to capture the moment, then the small, shirt-pocket size
digicams might just be item you're seeking. A number of companies, including
Pentax, Casio and Minolta have already introduced such models, each with their
own unique feature sets. Now, Contax, a name renowned for exquisite cameras
and excellent lenses, has jumped into the fray with their own version, the U4R,
a 4-megapixel camera sporting a Carl Zeiss Vario-Tessar T* lens. Those familiar
with the amazing image clarity of this line of lenses will immediately recognize
the name; those unfamiliar with it can be assured that it is a legendary name
in optics. The camera has just under a 3x optical zoom lens, delivering the
equivalent of 38-115mm in 35mm format. There's also a digital zoom if
you need it, delivering over 400mm, but as with many digital zooms it's
really a crop into the frame, and will not deliver the quality of the prime
optics.
