@Dearborn --- Thanks for this awesome post! I received my Tomlov Digital LCD Microscope Model DM201 Pro this week. Here is my first try at it... 1954-S RPM-003 I think I need a little more practice but this camera is very easy to use and I snapped these pics right on to my PC, no SD required.     |

Yep those are great pic for a first try, I don't think you need much if any adjusting.

If possible, could you show photos of your setup? Thanks

Looks like fun. The images appear a little flat--almost like shooting through a light fog. Can you control the contrast?

 . Kinda looks like there is a cap on the end of the scope that you forgot to remove? John1 |

Getting color accuracy is difficult with these USB scopes that don't have manual white balance adjustment. When I reviewed the Celestron 5MB, I ended up shooting coins on a True Gray background, and then adjusted the white balance on the photos. In the photos above it's hard to tell what true color is, since the upper photos have a very blue background hue, and the lower ones more or less magenta hue.
A Kodak Gray card or similar could be used and that would give a nice reference for accurate color.

14% gray background sheets can be bought on the bay for not much. John1 |

@Ham1947 - below is a picture of the settings I was using @ijn1944 - I had wide dynamic range on which disables the contrast adjustment. I do have an option to turn off wide dynamic range and then adjust contrast. I will try that out. @John1 - I checked the lens, only thing there is a UV filter, no other obstruction. @rmpsrmps - This microscope has an option to run a white balance calibration using a gray card. I will need to purchase one and see how it works.  |

I have thus same camera/scope. It's been perfect for quickly looking at coins without needing to break out the loupe. It's also very portable which was a factor in my decision to buy.

John1: 14% gray background sheets can be bought on the bay for not much. Yep always have one of them in my kit, from days when I was a pro pro photographer, (you mean 18% though not 14% grey) another point is many camera bags that are light grey on the inside, are also a 18% or "neutral grey" good for shooting a white balance shot and setting cameras in the field. That is the reason for the grey coloring inside more than anything from several professional photographer bag manufactures like LowePro, Tenba, Think Tank, Domke, etc. I know LowePro actually advertises their bag interiors are 18% neutral grey. The 18% grey was the middle grey in film days, and all meters were designed to measure off that, today in digital cameras the actual percentage used may be closer to the 14% or even 12% on digital camera meters to prevent highlight blowouts as CCD and CMOS sensors are so much more sensitive.
