<p>[QUOTE=&quot;messydesk, post: 4587017, member: 1765&quot;]This is a bit less standardized, more time consuming, and trickier.&nbsp; My process:</p><p><br /></p><p>1.&nbsp; Position the coin under the camera.</p><p>2.&nbsp; Pick up the lights, one in each hand, and move them around the coin, observing how the luster flashes, making sure that the amount of lighting the coin gets is consistent.&nbsp; You&#039;re doing this to plan how to take the pictures.</p><p>3.&nbsp; With your spare hand (you don&#039;t have one), pick up the remote trigger for the camera.</p><p>4.&nbsp; While moving the lights around the coin like you wanted, take 6 pictures to cover the lighting range.&nbsp; If you bump the camera or coin in the process, start this step over</p><p><br /></p><p>Next, crop them, save individually, and make them into a GIF.&nbsp; Lots of ways to do this, but this is my workflow:</p><p><br /></p><p>5.&nbsp; Open all 6 frames in a single workspace in Photoshop, with each frame occupying a single layer.</p><p>6.&nbsp; Crop to the bounding square of the coin.&nbsp; This will do all 6 frames at once.</p><p>7.&nbsp; Save the stack as individual frames with filenames image-1.png to image-6.png.</p><p>8.&nbsp; Use a bash or Python script and Imagemagick to do the circle crop and GIF composition, going in the following order: 1, 2, 3, 4, 5, 6, 5, 4, 3, 2.&nbsp; I delay changing from frame 1-2 and 6-5 by just a little so that when the loop repeats, it appears more natural.</p><p><br /></p><p>Steps 5-8 might not be feasible for your setup, experience, or comfort level.&nbsp; There are other ways to combine files into GIFs.&nbsp; Google is your friend here.&nbsp; 6 frames is the number I chose to keep a single side of a coin, using a 600x600 image down to about 3 MB.&nbsp; This made a pair of GIFs for a single coin reasonably e-mail friendly.&nbsp; I&#039;ve used 15 for a couple Dan Carr holographic coins, because they need it.&nbsp; I could use 100 if I wanted, but that starts becoming a huge amount of data to process and would be about 50 MB per side.[/QUOTE]</p><p><br /></p>
