Ok, I've got it figured out!!! Macro must be turned off and phone at least 7.5" above coin. Macro is the default setting and must be turned off by clicking the little flower. Next, position the phone on a stable platform overlooking the coin - minimum 7.5". I had been trying to use the same box as with my i7+, but it is 5". The i15 will not focus at that distance. I'm quite satisfied with the results. Here are a few examples: Bhutan 25 Chetrums 1975  Bhutan 25 Chhertum 1979  US 50 Cents 1995: 50th Anniversary of World War II  US 50 Cents 1992-S Columbus Voyage - 500th Anniversary  San Marino 5 Euro 2007: Equal Opportunity  Honduras 2 Centavos 1974  China 1 Fen 1937 (new photo)

Quote: Macro must be turned off and phone at least 7.5" above coin. That's interesting! I'll have to try that. I just upgraded from an iPhone 8 to a 16 Pro. The new camera is incredible, but I'm also having trouble with the lighting. I've been placing my phone only a couple inches above the coin and that captures the most detail, but then the lighting can be tricky. I'll try your suggestion. What level of zoom do you use from that distance, if any?

CollegeBarbers, it took me almost two months to figure this out. Once you move the phone up away from the coin, lighting is no longer the problem it was. Quote: What level of zoom do you use from that distance, if any? I try to keep it below 5X - enough so that the coin fills the frame but also leave some wiggle room for rotating the image. At higher magnification, the images have strange squiggly pixilation. This is a problem with very small coins, so with those I go back to the macro lens up close. I put the phone on this contrivance - a power cube box with a carpenter's pencil taped to it. Lighting is still an issue, of course. Having the phone at this slight angle does help, however. I'm using a Voncerus LED goose neck lamp which is really nice - https://www.amazon.com/Voncerus-Eye...B5ZBT42?th=1

Good to know, I will give that a try! I've been experimenting and found that coins with reflective prooflike surfaces from modern mint sets are the most challenging (I haven't tried regular proof coins yet). Circulated coins are definitely easier. Quote: I'm using a Voncerus LED goose neck lamp which is really nice Great, thank you! I'll order one. Right now I use two Jansjo lights and a table lamp with an incandescent bulb. Do you use more than one Voncerus lamp? What color mode and brightness setting do you use? Do you diffuse the light?

I just use one Voncerus - that's all you need. It has an integral diffuser, so you don't need to wrap it with a paper towel or piece of milk carton (like I've done with my other lights). I set it on the "normal" light - not the warm and not the "blue". It's set at max bright or in the upper range but I change it as needed. But for each, it doesn't seem to matter that much - the phone automatically corrects for both. There are times when I wish it wouldn't, but haven't figured out the proper settings for that. Proofs (especially silver) and other highly reflective coins (nickel-plated) are a real challenge. You're trying to take a picture of a mirror without getting a reflection of your phone. Also sometimes the coins appear black. Playing with the light angle and the phone angle often lets you get a good image. I also will hold a piece of white or black paper above the coin so that the reflection is lighter or darker as desired.

That makes sense, thank you! I ordered one. How do you ordinarily position the light relative to your phone and the coin? Quote: Also sometimes the coins appear black. I'm experiencing the same problem with some reflective coins. Quote: Playing with the light angle and the phone angle often lets you get a good image. I also will hold a piece of white or black paper above the coin so that the reflection is lighter or darker as desired. Those are good ideas! I'll try them. I have a lot of recent mint and proof sets to crack for albums, so I'll be taking plenty of photos to take of those reflective coins.

Great photos, Hondo. The proofs are especially nice.

CollegeBarbers, I have the light at the same level as my phone and perpendicular to the coin and phone. It's generally about 5" away from the phone, so it's about a 30 degree angle. I do move it back and forth or rotate it to get the picture to be the best representation of the coin. When you get pictures of the liberated coins please post them and tell us about your protocol.

I think I'm following you. I'll give it a try when it arrives and post my results.
What background do you use? I have an 18% gray card that I use, although I've also read black is better.

Quote: I have an 18% gray card that I use, although I've also read black is better. I use a white coin-flip insert. The phone's mysterious image processing sometimes turns it grey, sometimes not. It depends on how reflective the coin is. I tried using black cardstock but the coin color was shifted. Here are my most recent photos: Prince Edward Island Half Penny 1858  India 1 Rupee 1862  US 1 Cent 1839  French West Indies 10 Centimes 1839  Cuba 1 Centavo 1958  Jordan 1/4 Dinar AH1389 (1969) FAO  Slovenia 50 Stotinov 1992  Rwanda-Burundi 1 Franc 1960  Cook Islands 5 Dollars 1978

Quote: What level of zoom do you use from that distance, if any? At 7.5", zoom is definitely required. I zoom so that the coin almost fills the frame - roughly 10% slack - because I invariably have to rotate the image a bit when processing it. For some tiny coins, I will use 7X or more, although I don't fill the frame with them. Here's a tiny one - 15 mm. British Virgin Islands 1 Cent 1981
