Send files in 8bit JPG or TIFF/TIF format. If saving as a tif, make sure it is flattened and do not use Photoshop “LZW” compression when saving (“None” should be selected in the tiff options box)
- When compressing JPG files, be sure to use the loss-less setting of 12 in Photoshop. If you’re choosing compression at the camera, be sure to use the highest quality original capture and the finest degree of compression. At this loss-less setting, you’ll be able to adjust and save a file multiple times with very little quality degradation.
- Be aware that many camera and some RAW converters give you only a few choices, not the level you might want and need
