This part 2 video is about ether finding a photo or taking one that will work for this particular process. It does not matter if you are using a DSLR or simply a phone if you know what to avoid it will make everything easier. Bottom line is avoid yellows and greens "for this process" and focus on blacks whites blues browns and reds. Side note flesh tones work really well so keep that in mind. Part 3 will be on how to adjust the pictures and separate the negatives.
