I can't figure it out. My render (in a new window) is at 600x600. My background picture is at 600x600. Both at 72dpi. Look at this picture. The left is the image for the background as a BMP in photoshop, and the right is after I render the scene in Poser. See the difference? I can't figure out what the problem is since everything seems to be in order. Any ideas?
