How can you get ideas for design in Photoshop?
I will need to guess what ideas and processes you are hoping for as subjects for Photoshop. However, there are endless places to find inspiration.
Browse design sites and graphic art online. Look at fine art in museums, or anywhere. Contemplate nature for shapes and colors. Connect regularly with other designers and artists. The more you get out, connect, and use your mind and eyes the more you will absorb and store in your memory. And always take pictures when you can. Even pics of weird objects or patterns. It’s surprising how this becomes good reference for some future design work.
You can also start pinning design visuals you like on Pinterest. Use it like a digital bulletin board you would pin colors, shapes, and visuals you admire.
