Canon RAW files in Linux

2003-03-11 18:44:50.323895+00 by Dan Lyke 3 comments

Wow! Dave Coffin has C source for a whole bunch of RAW digital camera image file formats, of specific interest to me is the Canon D60[Wiki], but he's got Sigma[Wiki], Minolta[Wiki], Fuji[Wiki] and Nikon[Wiki] in there too. This means I can read RAW files under Linux.

My Sony has an option to store as an uncompressed TIFF.. Uses up LOTS of memory stick space compared to a jpeg, but the images are beautiful.

Does that give you 16 bit per channel TIFFs? That'd be nice because there's no conversion necessary. And conversion can be compute heavy and take a while.

One of the advantages of the raw files is that because the color interpolation hasn't happened yet they have a small, usually 12 bit, per pixel size, so they can be a lot smaller than a TIFF for the same application. Theoretically, the conversion (the Canon[Wiki] calls it "developing") takes a lot of CPU, too, so the less JPEG conversion that happens the longer the battery will last.

I'll go take a TIFF of something interesting.. and post it so you can examine it.. I wonder who I can get to pose.. and how :)
