I did this "painting" with Sketchpad Pro (by Autodesk) on my iPad. I did NOT touch it up on photoshop, this is straight off the iPad--I wanted it to be an untouched iPad picture. I spent several weeks working on it because Sketchpad pro is very slow (for me; I'm a newbie.) Sometimes, I used a pogo stylus, but mostly, I used my finger. I "painted" it from scratch, no photo was used. I did however, use a photo as a reference. The photo I used is one I took myself many years ago in the pouring rain. My mother stood over me with an umbrella. I did not paint all the droplets that were in the photo--that would have taken literally years to do. I just put a few representative ones in. See that floating leaf at the bottom? I tried and tried and it would not write there. So--too bad. The floating leaf is now part of the picture. C'est la vie!
