Error Struck Through | 2019P Struck through thread or filament at neck

Not sure what this is... it doesn't look like a die crack and it doesn't look like PSD either. Another thing that seems weird is, if you zoom in it looks like the little imperfections that are on the surface of the coin are showing up through the anomaly.

I'm having a hard time getting a pic of this... just when I thought I was doing well with the Ray System... I get a stumper!

Ray I have added the second image with no post editing to see if you can work with it, or if you want me to change some settings. To me the entire thing looks raised. At first I thought the top portion might be incuse but I think it's raised too. Thank you Ray!

It looks like Abe got all worked up over something, his veins are showing.

Viv...the image itself looks fine, so nothing to improve in processing it. Usually these subtle markers require specific lighting angles and such to bring them out visually. You might want to try moving the lights around, to lower angles, and maybe try just one light instead of two so you get better directionality. Shadows from two lights can confuse the eye. Or maybe the diffuser is eliminating shadows that are needed to see it clearly.

Edited to add: On closer inspection this looks like a small struck-through lint or thread. Based on the shadows it is incuse.

Great info Ray, thank you! These are the types of images that I have had the hardest time with so I really appreciate your suggestions! Let's see what I can come up with since you are seeing incuse and I am seeing raised

[ray_parkhurst]

Viv...think about where the light is coming from, and where on the anomaly the highlights show. From what I see, the highlights are on the bottom right. If the anomaly was raised, then the light must be coming from the lower right, but you are lighting from the upper left and upper right.

Yes Sir, thank you! One thing I'm confused with is... why am I seeing the little raised bumps (that are on the surface of the coin) at different places throughout the anomaly. It seems like a hit, whether it's PSD or a struck through, would have obliterated those bumps. Let's see if I can get the lighting to show it as incuse... that will probably answer that question - those bumps may not be bumps after all

Ray, while I had the 50mm lens on I tried a full shot of this. This shot is pretty dark but I think the shadows might be showing me something. The anomaly looks incuse at the top and raised at the bottom. So far this is telling me that it's just a PSD scratch.

Also... when I resize full shots to 864x864 I get an oblong cent so this one is sized to 1296x864. Oops... sorry attached wrong pic, going to find the right one now. Correct photo now attached. The sizing is messing up the clarity of the detail. This shot is not good focus and you can't zoom to see what I'm seeing prior to resizing. (I actually had the correct pic to begin with, it just looks out of focus after sizing)

Ray... sorry this is confusing. To try to un-confuse things a tad... I have attached IMG_1297 which is after post and has not been resized. This one should be better focused and you should be able to zoom it.

To make things even more confusing here's what I see has happened with the re-sizing when I open the photos in a tab.

DPP_0001296 that was sized to 1296x864 was actually resized through the forum settings to 1295x863
IMG_1297 that was not sized at all was sized through the forum settings to 1575x1050

so.. they both look unfocused compared to what I was seeing on my end.

I've added two screenshots to show the difference. Then I re-did the screenshots in Paint because cropping and saving as png seems to show the details better than the actual screenshot. (just in case you saw the previous ones and wondered why they have changed)

Viv...I'm indeed confused, but no more than usual! I can't tell much from the full-coin photo regarding topography of the anomaly. I spoke earlier about lighting, but specifically if you want to see things in "3D" you can use 1 light at a very low angle, ~20deg from horizontal. This will give a nice shadowing effect on all the surface characteristics.

I'm going to try some photo experiments to see what's going on with the resizing...Ray

Okay, thank you. I have added two screenshots to the previous post that might help in case you missed them. Thank you, going to try close up with just one Jansjo!

I agree with this being a struck through of a thread or filament or something like that. As far as all the photography chat, I haven't a clue

Thank you so much Bob for taking a look! Oh boy, now the pressure is really on! Seriously, I hope that you and Ray are right - it would be cool to have a struck through! Bob, don't feel bad... I'm lost here too while Ray is working on solving the photography problems of the world!

Okie Dokie... here we go! With Ray's super ingenious tips on how to shoot in 3D for newbies, this is what we've got! Ray, I'm using the 35mm lens at f4.5, one Jansjo 20 degree angle to the coin about 1" from the stage plate. While I was at it, I scooted the coin over with the exact same lighting and shot the die crack at the forehead. Also... I have not done any post edits or resizing to these shots so we'll just see how they show up once I post them. If they end up out of focus I will take a screenshot of them and try to add them that way.

Thank you so much Ray! I have struggled with trying to tell if something is incuse or raised for a very long time. Now, with your help, I understand why I was having trouble!

For some reason that technique is not well-known. I saw its potential when I did a lighting sweep from 10-deg to 80-deg to show the effect of lighting angle on the "look" of the coin photo, and it's pretty obvious that low angles really show off the topography. You could even go lower...10-deg is even more dramatic, but your 20-deg shots make it clear what is incuse and what is raised. Good job!

So, it does look like we have a struck through thread or filament just like you and Bob stated! That is very cool! Thank you both very much for your help figuring this one out!

Ray, you really are awesome! Thank you! Every single thing you have shown me to try... has worked... and this one really blows me away!
