What's the rig on the right of the picture that is holding the specimen and is everything mounted to that table or just sitting on it? [/quote] The "Ring" was a "pre-diffuser" It' was permanent and screwed to the table... the insect / object would stand in the middle... then the lens would go insid...

Tahnk you all after Savazzi's input now I understand what Rick meant to say all I have to do is to put a sensor N times smaller in the focus plane (working distance) .. N is the magnification of the objective then it's like the other post about the baffles in the tube. .. draw a loft from the "mini ...

Thanks Rick .. I read that post about 4 or 5 times and I think I understand the reasoning explained .. but elaborate on my own all the reasoning and calculations on the other side of the lens .. I am not able ... When I read that post about the baffles , I made myself a two-baffle tube with the help...

.... the old method was a frisbee, flying disk, with a beanbag. The frisbee really helps slide the heavy camera in close without disturbing the subject. The beanbag killed most vibrations. .... My white frisbee is still sitting in my office somewhere but I haven't used it in awhile. You know there ...

If you're using a lens where there is variation in perspective and magnification, then you're pretty much guaranteed to be getting parallax errors, so that might not be the best choice to begin with. But if you decide to live with parallax errors, then I think the best approach is to (A) be sure th...

3D Printed hood for mitutuyo

A friend asked me to design a 3D printed hood for his mitutoyo lenses. 5x (0.14) 10X (0.28 ) and 20X (0.28 ) The problem is, I don't have any. If I had, I would draw a prototype, print it, and then see what happened. I fetched the lens barrel dimensions from Mitutoyo's catalog and designed a CAD mod...

Thank you mark and Smoke... This is the reason why I photograph upside-down ... dead insects tend to bow their heads and antennae .. because they are dead. By inverting the insect gravity pulls the head and antennae down. After reversing the end result the insects have a more natural and "alive" loo...

"Tiles" and depth ...

Since I got the micro 4/3 camera I'm having a "problem" with the small sensor .. normal subjects (flies, wasps..) don't fit even at low magnification like 4X .. anything bigger than 4mm will not fit entirely.. even the head of a common fly is tricky to fit on a micro 4/3 with a Lomo 3,7x So many tim...

great idea and lovely results! Lee and Rosco make a variety of nice diffusion materials, the most common and useful one is probably Full White Diffusion (Lee 216). I find they are good value (around 10EUR for a square meter), problem is that they usually are sold in either full rolls or overpriced ...
