Hi Guys, Happy New year! I am applying SVA MFA Design, and the problem I am having right now is the works, which are in JPG format as they ask so, I submitted on SlideRoom turned out to be quite blurry! The size of my works are 1345 x 450 px, and the resolution are 400 PPI. I believe they should be clear enough to view, but they seemed compressed after I submitted them on SlideRoom which caused an obvious loss of clarity. I don't know if they look ok on the evaluator's side but they did look bad on my side. Does anybody have the same issue here？
