sooo - i'm giving a photoshop tutorial to a group of students in two weeks (twice actually, 30 per session) and I have to keep them entertained for about 7 hours (including breaks, so real time shedule is at about 5 hours).
while some of them seem to know a little about photoshop (and some of them are pretty hardcore), there's a good bunch of them not knowing anything about it and I'd like to not go in there and teach anything like "this button is the brush and you can paint with it [insert point and click gesture in the presentation]" but show them some more intuitive stuff.
while i see the need to teach at least the very basic UI elements, i'd like to push them to something productive. I thought about working with some kind of SDK and just have them pixelate some kind of texture for a lowpoly model but I don't know if that's appropriate for a real learning purpose.
so my question to you: what would you think is the most important lesson one should learn when starting to use photoshop? and what could be a small project to help them learn it (they have no tablets in this course)?
I tend to think to much into the direction of "this bevel and emboss effect looks shitty and your half-assed full-color-here,-gradients-there-style is awful" but seen from an objective point that's more a problem on the user's side, less on photoshop's behalf.
