Well, now I'm getting confused. In the above example, "needed a 5" x 5" picture, you would need a graphics render resolution of 1500 pixels x 1500 pixels", the graphic would STILL need to specify how many pixels were packed into an inch. Because if, for example, you had an image 1500 x 1500 pixels in size (with an additional specification of 100 DPI), the printed size would be 15 inches by 15 inches. So, if I am in Photoshop (with this image) and I want this image to print out at 5 inches by 5 inches, I need to alter the image dimensions. And anytime image dimensions are altered, the dots are altered with an algorithm. An algorithm that isn't perfect (and therefore adds a bit of distortion). Am I wrong?
