How 'big' is a 6 Mega pixel image? eg, 20 Meg? I ask for storage reasons Kind regards Kevin Hi Kevin, Direct from the camera, either a RAW file (with an embedded JPEG) about 7 MB. Large/fine JPEG mode (which I uses mostly and is fine for printing up nice and big, about 2.5 MB. File sizes

600*sizeofpixel. and pixels are 3 bytes in 8 bit/color, or 6 bytes in more than 8 bit/color mode. which comes down to either 18MB or 36MB. that is, if it's uncompressed format. for jpegs, it's only 8bit/color, and should be about 2MB (but it *really* depends on how far you are compressing it )

It varies a lot depending on the compression you use. I have a Minolta Dimage 7, which is 5 MP, and pictures can range all the way from 12 megabytes uncompressed to 1.5 megs at medium jpeg compression. You lose a little bit of texture with the smaller files, but the difference in appearance
