I still remember my teachers telling me that Photoshop is a design tool important not only for designers but also for people from different fields.
A great example is the grandmother’s old photo example where you have to clean-up a little bit a photo in order to be placed in your parentsâ€™ living room. Itâ€™s simple and with a little knowledge of Photoshop almost everybody can make that job!
This is a print-screen photo from a forum where a guy asks for Photoshop helpâ€¦ Unfortunately he hadnâ€™t the â€œlittle knowledgeâ€!!!
If you want to flex your p.shop humor skills or just kill tons of hours go to fark.com and check out any thread with a Photoshop tag. They’re usually pretty good about keeping it safe for work…usually.
I use CorelDraw fairly frequently for a few tasks. You can draw things to scale without plug-ins and it’s really great for detailed line work that you’re going to output via lasercutter, waterjet, etc. It’s missing most of Illustrator’s shading capabilities, and filters, but it gets the job done for little things.
I haven’t touched Painter since at least '98 myself either.
