Really? Photographically, these images are kinda crappy - the kind of casual snapshot one might take and then delete. The cathedral image, for example, is both underexposed and overexposed. I guess this isn't too surprising, since it was taken on a Nikon D70 from 2004, which had pretty limited dynamic range. This hardly seems like a good example to choose for testing image compression, since it lacks a lot of useful detail. Or maybe this was a deliberate choice? What were the actual criteria used to choose these images?

- jjmarr 2y agoMy first question was "what should I be looking for when this image is compressed?" A good compression algorithm should preserve important qualities of the image, but I can't evaluate that without knowing the qualities preserved.
