Prethen Pillar of the Community United States 3234 Posts	Posted 03/30/2008 1:32 pm Used F/11 at between 1/4-1/6 second and ISO 100. I tried all the way up to F/32 with no better results, just longer exposure times. I lightened these up a bit, although in hand it's a bit darker. I realize that the lighting has blurred out some of the obverse. Obviously, I have a bit more work to do. Edited by Prethen 03/30/2008 2:01 pm Report this Post to the Staff

hunter20ga Pillar of the Community United States 1173 Posts	Posted 03/30/2008 5:52 pm Very nice! Many lenses have a "sweet spot" between f/5.6 and f/11. These shots are lookin' good. I'm assuming the 20 cent piece is in a two-by-two or slab. That 3CN is great. (Neat die cracks on the reverse...) Thanks for sharing! I imagine we'll be seeing lots of great shots from you from now on! P.S. I often find that if I have to correct a little for underexposure, that a little tweaking of the contrast will help prevent a "muddy, washed out" appearance to the photo, and get me back closer to the actual appearance of the coin.

SsuperDdave Moderator United States 23522 Posts	Posted 03/30/2008 6:40 pm Is the '75 thru a slab? I may be hallucinating, but I think I see a little focus difference between the top and bottoms of the 3CN shots. I know this sounds anal, but I bubble-level my camera and the coin placement surface.... You're going to see the sweet spot for this lens between f/8 and f/14, unless I miss my guess. Do not be afraid to play with the image in postprocessing. The key is a realistic picture, not a perfect picture right out of the camera. If I don't specifically say that an image I post is untouched, then I've postprocessed it. That 3CN is a little Sharpening away from perfection. One heck of a coin, by the way. I want to call it MS, but I can't quite get past the serifs on the reverse. What's your grade, if I might ask? Report this Post to the Staff

Prethen Pillar of the Community United States 3234 Posts	Posted 03/30/2008 9:37 pm The 20¢ is in an ICG slab. I used to have a dog of a time taking macros (with a P&S) of coins in slabs, but I think this Macro lens will make the misery largely go away. The coins may not have been perfectly level with the camera; I basically guesstimated on the angle of the coins and the camera. The camera wasn't pointing down at a 90-degree angle. I don't have quite the setup to make that happen, so both have to be slightly angled. This is tricky at best. I probably need to develop some homemade material and technique to get that part right. The 1889 3CN is an XF. Due to the fact it's pretty much white, it's a foregone conclusion that it had been cleaned at one time, but not harshly. Report this Post to the Staff
MLFLY Valued Member United States 130 Posts	Posted 04/01/2008 12:42 am As was said, each lens has a sweet spot. For a small format camera, f9 +/- will do a respectable landscape which is much more difficult to render sharply from foreground to backgrond. Depth of field isn't the issue with a flat subject such as a coin. So, use the sharpest aperture. Report this Post to the Staff
