Lovely coins, all! This is for sure. I view this look as the definition of "original". It takes a long time to develop the dark silver sulfides...
Don't worry over your choice of lenses. The 150mm Sigma is excellent and will give you great results. The 180mm would indeed give you more working...
The guys over at GigaMacro have the equipment and expertise to image coins and produce a 3D model. They have done this for at least the Lincoln...
It helps if you can find an infinity focus setting. Some cameras have a "mountain" setting that fixes the focus at infinity. This keeps the camera...
Dave...try getting rid of the lenses before you give up on the Jansjos. Immediately diffusing seems to help a lot in getting rid of the chroma...
Sounds like it's time to stop using the incandescents and go with Jansjo LED's. You will have a much easier time with micro positioning the lights...
Here's a good thread that talks about lighting setups: https://www.cointalk.com/threads/coin-photos-lighting-requirements.275384/
The first pic you showed, taken with the iPhone, is an example of direct-reflection lighting. I've often called this "pseudo-axial", and it gives...
For a long time I segregated these "filled letters" die chips and sold them in rolls on eBay for a bit of premium.
I've had best luck using just a white 4x6 index card as a reflector, same one I use for white balance so that the card has no impact on the image WB.
Hi ManDime, I'm still building setups for folks. In fact I just shipped my 50th system! And they are all different. You can go to my website...
The W in WE is interesting.
Nope, it's still a proof coin. "Proof" is not a condition, but a method of manufacture.
I have hundreds of OBW rolls that I have kept intact in their original wrappers due to the inherent value of the unknown. I don't keep rolls from...
I've experimented with a few techniques for rendered imaging. Straight 2D stacking, rendered 3D, and even a few animations. I'm still trying to...
I've seen many coins that probably looked like this achieve high grades with market-acceptable tone jobs. It is actually hard to tell from the...
It's actually a good candidate for a coin doctor tone job. I'd bet a good doc could layer-on a market acceptable toning onto this one, which would...
How did you post the full-size image? Did you create the preview image as well? I assume your other posted images, with 4x redux, don't show this...
It's odd that the preview image appears to be extremely over-sharpened, but the full-size image is fine. It looks like the forum software is...
The 2x shots for both the 89PE and the 75ARD1 were stacked with ~7 shots. At this magnification and effective aperture it's hard to avoid...
Separate names with a comma.
