Wow. Just so that I understand--using the Rodenstock and the bellows, you refocused and pressed the shutter about 200 times and then combined the images in Helicon, which managed the merging automatically?
You get some remarkable effects. I'm also thinking of the pliers or wire cutter image you made.
Yes, that's it. I always start with the nearest point of focus, which is sometimes hard to determine from an angle like this, and, in fact, I think I did this one twice because the first time I missed the point of closest focus by something stupid like half a millimeter. But there was more to it than that because, as you focus the image size is slightly changing, you don't always know exactly where the crop is going to end up and I wasn't happy with the first crop so there were two reasons for doing it again. The wire cutters were 248 focus slices and that one I did at least three times and then re-did one section as Helicon was having an issue with the grain of the metal that in the end I simply had to retouch - kinda like I hit some sort of limit where it just freaked out and didn't know what to do. It completed the stack but there was a dog leg abrupt turn in the machined grain of the metal where that grain should have just been straight and nothing I could try in Helicon fixed it even when reshooting just that section by itself.
And all of these were cobbled together on my old 2017 iMac where Helicon took close to three hours when you drop 200+ 600 mb files on it at once. I'm just getting a brand new fully decked out Mac Studio with 192 GB of ram set up and have not tried it out on that yet but expect it to be significantly faster - or at least it better be - so at least the time factor of redoing things won't be so bad.
