Introduction to PhotoKit Color 2.0 - Pixel Genius

Summary
To recap, running a PhotoKit Color 2.0 effect on a file will add a layer or layer set containing
several layers. Not all file formats can save layers so you need to choose
whether or not to save the layers or flatten. If you do flatten, consider adding a file name
addition to avoid saving over your original file. If you need to save in a JPEG file format,
understand that it will compress your file in a lossy manner. You should avoid re-saving
over and over as a JPEG.
Both PSD and TIFF file formats can save layers. TIFF has a ZIP compression which is
the most efficient lossless compression scheme.
