<p>[QUOTE="SuperDave, post: 2506827, member: 1892"]The optical characteristics of the slab were an advantage here - the plastic simply <b>disappeared</b> in your images. I had to <i>assume</i> it was slabbed because you positioned this thread as a GTG. With that in mind, though, an added layer of complexity is imposed on the person evaluating the images, knowing there's the potential for slab plastic to alter the contrast and "reflectivity" of the actual coin.</p><p><br /></p><p><b>Terrific</b> images, man. It really doesn't get a lot better than this. Just for the record, what'd you use for aperture here? When shooting through slabs, I generally open the aperture even more than normal - f/5.6 or wider - to trade depth of field for better ability to make the slab "disappear" because at wider apertures it's even farther from the focal plane. That doesn't work well with 100% crops since the lack of DoF shows clearly, but with the "sharpness bonus" when you downsize large images, you end up with a better full-face image.[/QUOTE]</p><p><br /></p>
