Just set to HDR. Is that better? What are the options? You want whatever your phone calls medium. |

Your images are almost 2,000 pixels square with a compression of 48. Make them 800px square with a compression of 70. I can almost guarantee they will be immensely better. Plus, crop them closer.
. I believe this photo meets those parameters. Any noticeable difference to you?  |

Still kind of pixelated. What kind of phone are you using? I think maybe your phone camera just isn't that good unless something is moving when you snap it.

It is a rather cheap Galaxy A12. It must be the phone,there is no movement occurring during capture.

To me, one of the most important factors is lighting--using diffused lighting helps to reduce glare and fills in dark areas (to a degree). Of course, the physical limitations of a camera phone come into play in an unforgiving manner.

Yeah, that may be the issue. I have a Pixel 7 with the quality set to medium and it takes great pics.

Not sure why I missed this thread when it was first posted back in January.
I can't help with any issues related to the camera. I don't use a cellphone camera to shoot coins for various reasons.
What I do see is that there are some issues with lighting:
- The use of a single light coming in at 12:00 does not give the uniform illumination folks look for today. The classic recommendation of two lights, one at 10:00 and one at 2:00, is more uniform. If you don't want to use two lights you can simulate a 2-light solution by using something to block the light coming directly from 12:00. This will reduce the hotspotting seen on the top of Lincoln's hair and the top of the mottoes, etc.
- The light that is being used is at much too low an angle. You'll notice that the fields are fairly dark, as are the top surfaces of the devices, while the edges of devices (around 12:00) are brighter. This gives a Dark/Bright/Dark appearance. If you bring the light(s) up to a higher angle, more light will reflect from the fields and the top surfaces of the devices, and less from the edges of the devices. At some angle they will be about equal, and a little higher they will flip to Bright/Dark/Bright. This is what you're looking for with lighting, ie an emphasis on the surfaces of the fields and devices, de-emphasis on the edges of the devices, and some contrast between them.

Here's another attempt applying advice given. Am I moving forward or backing up. Thanks all for hanging in there with me  |

Looks like you moved the light to ~1:30, and maybe a little higher? It is a bit more evenly lit but you need to go even higher...

I took a break for a bit and decided to improve my set up. Stacking books and coin boxes to achieve the correct distance from coin to lens was always hit and miss not to mention frustrating and time consuming. This new setup is much, much better. I also added some additional light sources in an attempt to find the right combination. As stated previously by many of you, lighting determines everything. It takes a bit of time to find the right combination. Until I am able to upgrade my camera, this one will have to suffice. After trying many light combinations and adjustments, here is the first photo I decided to submit for critique. Compressed to 72, reduced to 800x800, a single light source p0sitioned about 3k to the coin at an angle about 2k approximately 20" from coin. Let me know what you think.  |

Oh my, that is a big step backward from the last photo. Weird colors, blown highlights. Still only one light. Why do you resist going to two lights? It would greatly improve your photos.

The lighting is pretty even and diffused, avoiding harsh shadows or bright spots on the penny's surface.
