As I believe I’ve mentioned before, I’m teaching myself Photoshop. As far as I can tell, one of the most important things to understand and use is layers. This is one of my first creations where I was beginning to understand how to use layers to change pictures in both large and small ways.
May years ago I worked at a silk screen shop. Silk screening required the creation of (as I recall) four separate screens (layers) in order to create the colors of whatever poster was being printed. Those colors were the primary ones: Red, blue, and yellow . . . as well as black. If the poster called for orange, then the area to be that color was open on both the red and the yellow screens. Same thing for green, purple, brown, etc.
The thing I remember most about working there (I was in my very early twenties) was coming home higher than a kite at times. This was because we used a lot of toluene as a solvent for creating and cleaning the screens. There were days when I breathed in a lot of that stuff. There were no requirements to wear masks and I don’t think there were many, if any, regulations in place regarding adequate ventilation, etc. Now that I think about it, it’s a wonder I can recall anything about that job. I did enjoy the work, though.
So here’s an early picture I ginned up using PS. It consists of seven layers:
