<p>[QUOTE=&quot;-jeffB, post: 2359262, member: 27832&quot;]Well, not necessarily.</p><p><br /></p><p>Point a camera at a flat surface, parallel to the camera&#039;s focal plane. Draw a rectangle that exactly includes the camera&#039;s field of view (with the lens that you&#039;re using). Arrange things so the field of view is several times wider than your coin.</p><p><br /></p><p>Now, put the coin in one corner of that rectangle. Take the picture, then crop it to only show the coin. Presto! You&#039;ve taken a picture that will show one edge of the coin, but has the entire coin equally in focus (assuming your lens is up to snuff).</p><p><br /></p><p>There&#039;s actually a specialized &quot;tilt-shift&quot; lens type that lets you do this while filling the camera&#039;s FOV with the subject. It&#039;s used more for architectural photography, but could be used for this as well.</p><p><br /></p><p>I actually scored big because of this once -- a large-volume eBay dealer listed a roll of proof Kennedys, neglecting to say whether they were silver. Because they were laid out in a rectangular array, I could see the edges of some of them, and could clearly see that they were not clad, even though the whole array was in focus. There was at least one other bidder who spotted it, but they wanted it cheaper than I did, so I won, at less than half melt.[/QUOTE]</p><p><br /></p>
