Test of new imaging procedure

Post by dans40 » Sun Nov 26, 2023 4:30 pm

Hi all, I'm trying to decide if I should continue to re-image all of my coin images for my own personal online collection. Below are examples of the old imaging method (the dark ones), and the new imaging method (the lighter ones). It's the same coin, I just need your opinion on what procedure you think is the better one for taking photographs of my set. I may have to rescan about 2,000 coins (I haven't counted but it's a lot).

Of course, you can absolutely see more detail in the new one, but I feel that it's a bit washed out and I don't know how to "fix" it (if you think it needs "fixing"). I've been debating with myself whether I want to scan all my coins all over again. I just need some wise advice from the community. Sorry for the size of the second one, it's 800x800, I guess I could have reduced the size further. I didn't know how to size it in the inline attachment.

Thanks so much for reading this and providing your input, it'll be very helpful.

Hello! :)

Nothing is better than natural lighting and a good camera. All scan make coins look like washed up like this.

I kind of got it, I'm using my coin microscope to take pictures of my coins but the height of the camera is only 7", and it's not ideal for large coins. But I just took these photos and processed them in Gimp to round crop them, and corrected the levels by using Colors/Levels/Auto Input Levels (again, 800x800) but nice detail and nice (sort of) lighting, so you can see all the details without it being washed out. It's harder on older darker coins because you get so much shading.

But, if I have to do this with 2000+ coins, I'll be here until I'm 90.

I dont know why you take pictures of all your coins.

Valuable ones, ok. Common ones, just keep old pictures.

It's so I can catalogue everything I have, and it's good for insurance purposes in case it ever gets stolen.

I dont think it matters for the insurance if you take new pictures of them or not

Have you tried turning you microscope so that the scope is perpendicular to the base and then placing blocks under the base to achieve more than the 7".
