Which goes to show how much I know about digital images. Also, I'm very shallow... the 50MB part impressed me :-)

My 10 megapixel Canon 40D produces raw (14 bits per pixel) images that
average 10MB each. If I convert these to 16 bits-per-pixel TIFFs, they
end up at about 60MB. The corresponding camera-generated best-quality
JPEG is about 2.5MB.
My point is that the size of an image in megabytes depends on several
things: number of pixels in the image, number of bits per pixel, amount
of compression (lossless or otherwise) etc., and is not in itself a
useful measure of 'quality'.
