Best way to upload 5d3 pictures here?
Well, since dpreview has a silly 20 megapixel or 20 megabyte file size limit, I just decided to resize to 5400x3600 pixels and save as quality 97 jpegs. That is the original 3:2 aspect ratio and 19.44 megapixels. That should be plenty of resolution to show detail in your files. Here are some files I uploaded at that size recently.
