How do I prepare files for custom printing?
If you didn’t take the picture as a raw file, send us the original (unedited) file. It is usually a jpeg or tiff file.
Don’t change the image resolution or file size. If you’ve edited the file on your end for color, done retouching or compositing, or other file manipulation, please send a TIFF file of the edited file, in addition to the raw file.
Do not change the file size or dimensions – please send the file at its native resolution (i.e. as the camera captured it).
