iPhone 5S, Snapseed, iColorama, Phonto
My little turtle buddies, one in full white paint and the other in chipped white paint, just didn’t show up well, they were more like white blobs. So I used Snapseed to try and sharpen the image up. No luck. Then I went into iColorama and used congruence to give some texture and at least you can see the faceted plates on the back. Then I fiddled with the coloring until it was pleasing. Used a framing app, don’t remember which one. Phonto for the signature and it came out looking pretty good.
