Hopefully you can see what I meant about the washing out of the photo with the wrong backing. I usually play with the colors until I get it right. Different color backing for a nickel/dime than for a brown cent. Have some fun with it. You'll note that those photos were taken with an iPhone 5 with a weak camera relative to modern phones. But it's a fun challenge!!
I found an inexpensive source (a.k.a. Walmart). I buy their brand since it has a better matte finish which keeps the reflective nature of other brands (post-its) a way from my fine prints!! LOL Actually, if you notice, the texture of your background might be causing some of your focus problems. Also, you can soften your lighting with a white plastic bag from the grocery store. There are a few things that you can try. I'm playing with an old shoebox for a photobox setup. I'll show that at some point.
Very cool. Yes I think I put too much lighting and my lamps make the coins have a yellow tint. Thank you. I will take a pic of it. Thanks again.
Finally I see pictures! What was everyone else seeing at the beginning of this thread? All I got was a D.
A completely black background has always worked well for me when taking very close-up pix of coins with my cell phone. Perhaps because the cell phone "sees" just the coin and only tries to focus just on it, not anything around the coin.
Not really. I change out the backing color relative to a particular coin. As noted, black works well and is my normal default as it absorbs extra light bouncing around. My black backing is also my mouse pad, and at present, buried under coins....so...a blue post-it was used, primarily to demonstrate the difference in using a chartreuse background and another color (blue in this case). But I will use blue when it's not upsetting the camera's autofocus.
