<p>[QUOTE=&quot;RonSanderson, post: 2594586, member: 77413&quot;][USER=1892]@SuperDave[/USER] made me rethink the use of my Sony superzoom and my wife&#039;s little Nikon point and shoot. Both have zoom.</p><p><br /></p><p>So I went with the iPhone instead. This simplifies the setup. The toilet paper roll is not fancy (!) but the closest focus for an iPhone is about 4 inches. The white paper also keeps the brown cardboard of the roll from reflecting onto the coin and affecting white balance.[ATTACH=full]565261[/ATTACH]</p><p><br /></p><p>I am using Camera+ on the phone. It gives me precise control over all features. I use -0.7 eV to keep from blowing out the highlights. You can make out a circle and square overlaying the image, like this.</p><p>[ATTACH=full]565262[/ATTACH]</p><p><br /></p><p>The square sets the focus area, and the circle sets the area to use to compute auto-exposure. The slider at the right is a digital zoom which I set to 3.4x. That lets me use the grid lines on the display to position the coin perfectly straight.</p><p><br /></p><p>This is the mounting for the coin.</p><p>[ATTACH=full]565272[/ATTACH]</p><p><br /></p><p>The black foam serves as the backdrop. It is a dime holder so the cent sits on top of it. The 2x2 holder gives the foam some support so I can move it around easily. The gray card is homemade and is used to check exposure and white balance. The black felt underneath is just another background I was trying. The two strips of museum board allow me to adjust the angle of the coin.</p><p><br /></p><p>Finally, this is an early result. All I did was move the TIFF files to my PC and crop them to size.</p><p>[ATTACH=full]565275[/ATTACH]</p><p><br /></p><p>This is a reverse with a bit more tilt toward the lights. It has great color but seems harsh to me.</p><p>[ATTACH=full]565286[/ATTACH][/QUOTE]</p><p><br /></p>
