"Photoshop did something weird; it doesn’t work the way you said it would," said one of my students in a Photoshop class.
True, I’m not always right about how Photoshop works. I’m not always right about how ANYTHING works. But every other student in the class got the expected result.
"Well, let’s see what you did that’s different or perhaps you did it wrong," I replied as I headed for his workstation. "No way," he averred, "I did it exactly according to instructions."
I performed the operation according to instructions and got the predicted result. ”That’s what I did,” he insisted, “and it came out wrong.”
I performed the operation from a slightly erroneous starting point. I got his result. “No, I’m sure I didn’t start that way,” he maintained.
I repeated the processes a couple more times. Same results.
Me: “So if I repeatedly do it one way and get the predicted result, and I repeatedly do it another way and get YOUR result, you still believe Photoshop is at fault here?”
Me: “Do you usually vote in elections?”
Student: “Yes, why?”
