Find the Difference

Learning Photoshop requires a large amount of repetition, not unlike learning to sing or paint. As a way of reinforcing that, the latest little project is to take a photo and make a modified copy that has various additions, changes, and deletions. Take a shoe, for example, and change its color, or rotate a cup about its vertical axis, or make a copy of a car in the background and put it somewhere else on the photo. All of that fundamentally involves developing the ability to use a couple dozen different selection methods (or so it seems; I haven’t actually counted them), learn which pixels to include or exclude at the edge of the selection, put the selection on a new layer and then using one or more of the many color, size, and orientation manipulation methods to alter the selection. The result of the project is to present the before and after images and see if someone else in the class can spot all the changes. So I present to you, dear reader, my modest attempt, which contains nineteen changes. See how many you can find.

The photo is of the Ca D’Zan in Sarasota, Florida, built by John Ringling of circus fame.

Okay, are the 19 including the slight color changes? And I can't see their shoes - how can I tell if you changed their color? LOL

Yes there are color changes and some are rather subtle, but every one is visible. If you can't see someone's shoes they probably aren't wearing any; it is Florida after all :-)

This is way to hard. I could only find three distinct things (not color).

I never did like those "find what's different" games in Highlights magazine!

Most of them are pretty mundane: change color, remove object, add object, rotate object. The one I had the most fun with was putting a clone of the blue woman in the second floor window, fifth from the right (start counting at the edge of the picture). I put a copy of her, rotated to face left, on top of the background, then a copy of the window without the window panes on top of the woman, and then the missing window panes set to a low opacity on the very top.
