What's your lighting setup like? Do you try and light the coin from all angles to decrease shadows? Do you have an issue where you need to move the light to take a photo from a certain angle, and if so does that cause problems for the model or do you try and not move the light at all? These are great! I've been wanting to do this for sometime myself but other projects keep getting in the way, mind if I ask a few questions?ĭo you rotate the coin around an axis and take photos from a stationary position, or do you lay the coin flat and move the camera around/above it? Given the consistent lighting, I'm assuming the latter? I used a similar setup for doing 360 degree photos of my coins but in that case didn't bother about trying to remove the blu tack holding the coin in place.
HELLENISTIC COINAGE SOFTWARE
Good tip about the polarizer sheet, I noticed mine would warp due to the heat of the studio light, I hadn't considered that when I first bought it.įor the focus stacking, do you stack manually or with an automated rig like a StackShot? And for the alligator clips holding the coin, I assume you're able to tell the 3D software to ignore that part of the image when combining all the photos and to instead use the images where that part of the coin isn't obscured by the clips? It's been awhile since I last attempted this so can't quite recall what my own workflow was. I have a similar camera setup to you though, the Laowa 100mm macro and a Sony A7R III. I have a considerably cheaper Godox SL60W, which struggles to provide enough light on its own. Those studio lights are killer, no wonder you were able to get such good lighting on them. Thanks for the info! It sounds like I was on the right track with my own plans, so that's reassuring. You also want to get the light to be as even as possible across the subject, as shadowless as possible, because the shadows will end up baked into the model. Depending on the situation, lighting, subject or other variables, you might want to shoot against white, for example. The point is to isolate the subject from the background. The scanning in the void method that you mention is a great way to think about it. I shoot against a black backdrop, or sometimes white, sometimes without a backdrop. The lights are to either side of the lens and subject at about 45 degrees. The turntable is bought from amazon, the subject is held with an alligator clip on a stand. I have two Paul Buff Einstein 640W studio lights with 8" reflectors covered by American Polarizer high-heat 39% transmission polarizing film (this is important when other film starts to melt). Lens choice varies, but these are mainly shot with a Laowa 85mm f/5.6 X2 Macro lens on a Sony a7ii body.
24 per side is pushing it 72 is way more than you need if you're focus stacking. I shot a little over 800 shots, focus-stacked into 46 - 60 composite images.
