Joe, I just saw this thread, and went to check out a few of my images. Specifically, longer horizontally or vertically than basic 8x10 ratio. I think what you're seeing might be that with the standard or framed print or greeting card, the image is 'flat'. With the canvas, acrylic, and metal, it seems a little more 3D to show the side/depth of the finished product. Could that be what you're seeing?
