JohnAP Valued Member United States 245 Posts	Posted 05/20/2008 5:59 pm OK, here's step number 1 in the SuperDave method. Specifics: Camera: Canon A650 IS Settings: manual ISO 400 aperature f 5.6 exposure 1/125 custom white balance lens set in macro mode center weighted average metering 10 sec delay shutter release camera lens aprox 12" from coin superfine image quality lighting: 40 w incandescent (2) at aprox 10 oclock and 2 oclock aprox 12 " from coin The only post picture processing was cropping, sticthing, and resizing. http://www.coincommunity.com/forum/...non1both.jpg I'm workin on it! Step #2 camera moved to 8" from coin all other parameters the same as for step #1 http://www.coincommunity.com/forum/...nonboth3.jpg hmmm....camera wants -2 f stop Step #2 a all parameters the same as in step 1 and 2 EXCEPT exposure time changed to 1/25 http://www.coincommunity.com/forum/...nonboth4.jpg better, but still a LONG way to go....shoulda started with a less shiny coin? Step 3....we're at 4" starting to get there but..... all parameters same as for 1 and EXCEPT metering mode...switched to "evaluative" http://www.coincommunity.com/forum/...seCanon6.jpg http://www.coincommunity.com/forum/...seCanon6.jpg where's that blue coming from? Lets try some copper.... http://www.coincommunity.com/forum/...obverse1.jpg http://www.coincommunity.com/forum/...reverse1.jpg hmmm....and I reset the white balance for each coin....what gives? The penny is a nice shiny modern coin...... Edited by JohnAP 05/22/2008 5:42 pm Report this Post to the Staff

hunter20ga Pillar of the Community United States 1173 Posts	Posted 05/22/2008 10:41 am Yep...start with brown copper. I've always found it to be the easiest to photograph. I would also suggest using a coin that grades VF or higher so there is plenty of detail left to focus on. In other words...dull, brown coins are typically the easiest to photograph; very shiny, silver coins are the hardest. (I confess, I've not shot gold coins, but would guess that shiny gold is harder than "dull" gold coins. Report this Post to the Staff
Learjet Pillar of the Community Australia 655 Posts	Posted 05/22/2008 12:22 pm Shiny gold or silver is difficult, unless the coin is perfect. Tiny barely visible marks and scratches turn into canyons. There are only two coins I can't photograph properly. Pad printed colour and mirror surface gold. Report this Post to the Staff

How much sunlight is there in your shooting room, and were there clouds moving across the sun? Sunny vs. cloudy skies are entirely different white balance settings. Report this Post to the Staff
JohnAP Valued Member United States 245 Posts	Posted 05/22/2008 6:43 pm SuperDave, Sunlight was constant for both sets of pics. Not a cloud in the sky. I'm wondering if the camera is overcompensating a bit for the incandescent lights, which would explain a lot of the diference between the two when switching from the black background to the white? (in both cases, white balance was set using 2 sheets of white paper, filling the view finder) Report this Post to the Staff
