    I don't have/use photoshop but I'm really curious to see if this works well for doing axial lighting on slabbed coins, especially when the axial light source is small or something like an LED strip with no diffuser. If the reflection is overexposed will it spit out an error message or is it using some AI generative fill?

      The 1st was in camera raw: remove, generative AI. The 2nd using camera raw: distraction removal, reflections. Not much difference.

      It does not look promising.

      I believe that is a polarizer, and no it does not work for axial. Gives the coins weird colors, and I did try it.

        ToddPollock right but a smaller light source really makes all the die polish lines etc pop. I'm curious too if with the right depth of field if it can remove scratches in the slab. It might not be appropriate for photos, but for videos where a mistake in the autocorrect in a frame here or there won't be noticed it might work very well if its fast enough to batch edit with. In the past when I did batching with PS though it seemed the majority of the time was just opening and closing files. There must be someway to multithread it or preload files.

        FriendlyEagle7 Ok, I did the photoshop edit. It does a bad job on coins in general, because it needs to be so exact for coins and the AI is just guessing on what is actually there. This makes some areas look super blurry and they aren't actually true to the coin.

        FlyingAl was the part that wasn't true to the coin completely blown out in the original though?
        I still don't like the idea of AI generating anything. I can see using AI to identify the reflection and do noise reduction in the areas where there would be no dynamic range left, but if it doesn't throw an error and instead just does generative nonsense in blown out areas thats a huge nope from me.

        here is a test of another dehaze tool that lets you tweak the size of the glare, but I don't like how it makes every scratch on the coin stand out

        FriendlyEagle7 Yes and no. I think a lot of people would still find using the AI to be unethical. Dehaze preduced a better and more accurate result.

    Stumbled across these today, a good example of axial vs. normal light.

      Beautiful! I cannot get axial to show such detailed contrast on the devices. I cannot get it to show real luster on the backgrounds tho.

    Thoughts on ways to deal with green copper?A bit too much green came through on these versus in-hand, even in-hand under bright light. It should be there but faint.

      To me green always comes through more than some other colors. I have found PVC on a coin when I could not see it in person yet the images had the bright green bubbles.

    Same coin, same camera, two different methods of photography. In-hand, it has the discolorations of the duller image (LED-lit), but with the luster of the brighter photo (axial). How to get one image with both?

      put a dimmer switch on one or both lights and take the photo with both lights on, using the dimmers to adjust how much axial vs off axial light you get

        FriendlyEagle7 They’re not adjustable, but could something work as a makeshift dimmer or filter?

        AmbrotypeVisuals it would be easier to just photo stack. Take a pic with one light, turn it off and the other on, take another pic (don't move the coin/cam between pics) then in photo editing software overlay the images and adjust transparency

    Two 1964 Kennedy Half Dollar Proof Coins
    Just a little difference in color between the two.
    Nothing special here I guess.

      Kennedy on the right got more hair maybe due to the location of the light source.
