<p>[QUOTE=&quot;RonSanderson, post: 2938493, member: 77413&quot;]I now have a new setup, courtesy of Ray ([USER=31773]@rmpsrpms[/USER] ) over at <a href="http://www.macrocoins.com/" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.macrocoins.com/" rel="nofollow">www.macrocoins.com. </a> This is a variation of his system #1, with a special modification.</p><p><br /></p><p>[ATTACH=full]715219[/ATTACH]</p><p><br /></p><p style="text-align: left"><span style="font-size: 16px"><font face="Verdana"><span style="color: rgb(20, 20, 20)">I contacted him about rotating a coin under the camera while tilting it at an angle. This has been my standard approach to making animations. To make it work, I wrote some software to realign the images. While it works pretty well, there is some residual swaying when the algorithms cannot align the rotated images with sufficient accuracy. </span></font></span></p> <p style="text-align: left"><span style="font-size: 16px"><font face="Verdana"><span style="color: rgb(20, 20, 20)"><br /></span></font></span></p> <p style="text-align: left"><span style="font-size: 16px"><font face="Verdana"><span style="color: rgb(20, 20, 20)">Discussions with Ray led to his devising a new invention, shown here.</span></font></span></p> <p style="text-align: left"><span style="font-size: 16px"><font face="Verdana"><span style="color: rgb(20, 20, 20)">[ATTACH=full]715220[/ATTACH]</span></font></span></p> <p style="text-align: left"><span style="font-size: 16px"><font face="Verdana"><span style="color: rgb(20, 20, 20)"><br /></span></font></span></p> <p style="text-align: left"><span style="font-size: 16px"><font face="Verdana"><span style="color: rgb(20, 20, 20)">The coin is placed on the platform and does not move during the shooting. </span></font></span></p> <p style="text-align: left"><span style="font-size: 16px"><font face="Verdana"><span style="color: rgb(20, 20, 20)"><br /></span></font></span></p> <p style="text-align: left"><span style="font-size: 16px"><font face="Verdana"><span style="color: rgb(20, 20, 20)">The lens has been modified by adding a rotating collar. On the collar is a bank of 9 small LEDs. I rotate these to a number of different positions to get lighting from different angles. (In the first photo you can see that I use one Jansjo for overall fill lighting, so the rotating light source is a second light source.)</span></font></span></p><p><font face="Verdana"><br /></font></p><p style="text-align: left"><font face="Verdana"><span style="font-size: 16px"><font face="Verdana"><span style="color: rgb(20, 20, 20)">My new images are three times the size of my previous camera, but I still downsize them to 800x800 for publishing. (The originals are kept unharmed in case I need them some day in the future.)</span></font></span></p><p></font></p><p style="text-align: left"><span style="font-size: 16px"><font face="Verdana"><span style="color: rgb(20, 20, 20)">I modified my software so I fine-tune the rotation of one image (say, by a degree or so) and draw a cropping boundary around the coin. Then I apply the same rotation and cropping to all the images. This is easy since the coin and the camera never move. With these cropped images, I am ready to join them in obverse / reverse pairs, and combine those paired images into an animated GIF file.</span></font></span></p> <p style="text-align: left"><span style="font-size: 16px"><font face="Verdana"><span style="color: rgb(20, 20, 20)"><br /></span></font></span></p> <p style="text-align: left"><span style="font-size: 16px"><font face="Verdana"><span style="color: rgb(20, 20, 20)">Here is my first result with this new equipment and workflow. There are seven photos of each side, shown in the order 1-2-3-4-5-6-7-7-6-5-4-3-2-1, and using an elapsed time of 1.1 second to move from image 1 to 7.</span></font></span></p> <p style="text-align: left"><span style="font-size: 16px"><font face="Verdana"><span style="color: rgb(20, 20, 20)">[ATTACH=full]715223[/ATTACH]</span></font></span></p> <p style="text-align: left"><span style="font-size: 16px"><font face="Verdana"><span style="color: rgb(20, 20, 20)"><br /></span></font></span></p> <p style="text-align: left"><span style="font-size: 16px"><font face="Verdana"><span style="color: rgb(20, 20, 20)">Thank you, Ray!</span></font></span></p><p>[/QUOTE]</p><p><br /></p>
