<p>[QUOTE=&quot;brg5658, post: 1486054, member: 29751&quot;]Are you shooting with a tripod or a copy stand?</p><p><br /></p><p>If you&#039;re using the Canon T3 you have a very nice camera.&nbsp; All of my recent shots are taken with a Canon T2i.</p><p><br /></p><p>To get what you call an &quot;evenly distributed&quot; depth of field you have to make sure that the plane of the camera sensor (the little rectangle at the back of the lens that captures the image) is exactly parallel to the coin surface.&nbsp; One clever way to do that (that I learned from someone else) is to use a very small mirror.&nbsp; </p><p><br /></p><p>Process:&nbsp; Place your coin on the table and frame it in the viewfinder and focus on it.&nbsp; Then, move the coin and place a small mirror on the flat surface in it&#039;s place.&nbsp; Now, using the LiveView mode of your T3, see if the middle of your lens is exactly in the middle of your viewfinder.&nbsp; You should be able to see the reflection of your lens in the mirror -- position the middle of your lens reflection in exactly the middle of your viewfinder and that will guarantee that the two planes are perfectly parallel (the sensor and the flat surface you&#039;re shooting on).</p><p><br /></p><p>Another thing I wonder is what f/stop you are using.&nbsp; Almost all coin images should be shot in the f/5.6 to f/11 range (not smaller and not larger).&nbsp; This is the optimal range for most macro lenses to maintain sharpness and decent depth of field.</p><p><br /></p><p>Does this make sense?&nbsp; If not I can try to explain a bit better.[/QUOTE]</p><p><br /></p>
