I'm hoping I'm doing this in the right place. I've been doing photography for about 6 months now. For some reason when I upload my pictures to Facebook they look very pixelated!? I will look at others pages and their pictures will be crisp and clear! I don't get it? I don't use a high ISO, nothing over 400. So I don't it. I resize them in Photoshop and I size them down to 450. Can someone give me some insight? Thank you.
