<p>[QUOTE="dougsmit, post: 3273091, member: 19463"]The program I use requires that you input the images in proper order with the one focused most closely first. This can be done in either of two ways. The easiest is to focus manually on the nearest point and shoot picture #1. The move the focus ring the smallest possible amount in the direction required to move the plane of sharp focus down just a tiny bit. NEVER back up. Repeat until the sharp focus reaches the most distant part of the coin. If, when you finish and the program has done its work, there are fuzzy spots in the coin, you probably have a bad image or did not make enough steps along the way. Combines starts by calculating the offset (x and y) to correct the centering of the input images. If it displays over 10 pixels, I throw out the image that is different or start over and be more careful not to move the camera when focusing. You need a solid camera stand for this. You can use that expensive tripod if you must but a camera stand made of scrap lumber is more solid and costs a fraction as much. </p><p><br /></p><p>You can also leave the focus setting alone and move the camera and lens down closer to the coin with each shot by the tiny amount. I have found the program to be forgiving of the amount as long as you adhere to the near first and far last rule.
