Course Presentation Canvas size?
I had created some slides is Photoshop for my course presentation at (900 x 506 px) about three weeks ago.
Today I modified my slides (basic color changes) in Ps and went to upload them as the "background" for the course presentation, which now appears to have a different aspect ratio? Perhaps I am missing some information, could someone please advise?
What size do you reccomend makng slides?
