Aren’t TIF and RAW images better quality than JPGs?
Under normal circumstances, no. JPG images use “lossy” compression, which means that each time you save an image file as a JPG you throw some of the image’s color or detail away. If you save an image as “best quality” JPG, the difference is invisible to the human eye. However, if you repeatedly open, change and save an image (for example, in Photoshop) you should save intermediary files using a “lossless” format like PSD, TIF, or RAW, then save the final version as a JPG before submitting the order to the lab.
