your last link is broken (for me) is this the publication you were referring to? https://www.osapublishing.org/oe/abstract.cfm?uri=oe-25-14-16652 Yes! Thanks for pointing that out. Here are a few more links on the technique, in the interest of keeping these posts informationally dense: https://dash...

10-4 - I may have to reach out to Linden Gledhill and ask for his permission, this is a very interesting technique! On my calibrated monitor I prefer the original; on a smartphone screen I prefer the revised version, but the highlights are a little strong for my taste (note it's very, very subtle). ...

Thanks for the links! Those are some impressive results; shells certainly aren't the easiest thing to capture, with all the nooks and crannies. I know what you mean re Agisoft - They seem to be the major player in this world, but I'd need to figure out how to monetize this hobby before I could justi...

Does the tilt stage also rotate? Totally out of left field, but it's been on my mind a lot lately: A macro-photogrammetry rig .... Yea, that's the concept. No, the tilt stage doesn't rotate but I have one that does. Just looking for something different to do. -JW: My previous post was vague - By ph...

Does the tilt stage also rotate? Totally out of left field, but it's been on my mind a lot lately: A macro-photogrammetry rig. Turn down the lead screws on the tilt stage knobs to couple some NEMA 11 or 14 motors, drill and tap the stage + 3D print some brackets for mounting the steppers. Might need...

I can't comment on that particular scope, but here's a link that might help a bit with something: https://www.microscopyu.com/tutorials/matching-camera-to-microscope-resolution I'd recommend against a FF camera - A used micro 4/3 or APS-C body would be preferable. Most objectives aren't designed for...

Total shot in the dark without having access to the files, but perhaps it's some weirdness going on with the way DPP4 handles RAW demosaicing, specifically where it chooses to crop the edges. I'm seeing 5472 × 3648 quoted as the max effective resolution for the 7D Mk II from various sources, smaller...

Thanks for sharing; directly coupling the specimen holder to a stepper motor is an awesome idea! I've been scratching my head on how best to go about adding a rotational axis, and this looks like a pretty perfect solution - about as low weight as one could get. Looks like a ~64oz-in motor, based on ...

Regarding telecentricity - is there a guide you know of showing how to convert a normal telephoto lens to one with a 0 degree field of view? This might be a really great effect, lending a sort of scalelessness to the images, although if I'm not mistaken, it will mean I'm shooting everything at 1:1 ...

Re: Advice for beginner photographing small artwork
I have a few questions I could use help with - macro is a new world for me. 1. Does anyone have experience combining panoramic techniques with focus stacking? Doing one or the other is easy, but doing both is tricky. Should I make the panoramas first, then stack? Or focus stack and then combine in ...

Thanks Rik! I agree, the ball-in-socket joint is one of my favorite features of these little guys. Reflecting after reading your post, I agree, 'seriously out-resolving' is overzealous. I guess my quest for giant prints is making me a little too sensitive to resolution. Before I started testing this...
