Very nice picture!
Thanks for the information about your work process. More than 300 images with a manual rail, impressive.
Best regards

Hi Adalbert
An interesting, nice and good display of different ways to show the 3d structure!

Re: Eggs on a salad leaf
@JayMcClellan Thanks for the nice comment! Stereo pictures are a bit more demanding to retouch. So I usually try do make them as clean as possible in Adobe LR before stacking. The new AI feature to remove noice helps but for me the most import step is to try to eliminate all dust spots and hot pixel...

Thanks for the nice comment!.
Rearing would have been interesting, but no at least not this time.

Eggs on a salad leaf
Hi
My wife found some eggs on a red salad leaf. So I made a pair of "crossed eye stereo" pictures. Nikon plan apo 10x NA 0.45.
Best regards

Hi Rik
Interesting and informative. The stereos are really nice. Looking forward to the description of the preparation process.

Re: The new bargain: PL M 100 / 0.90 ∞
Hi Adalbert
Interesting lens and topic, thank you.
I think it is quite possible to do ok with a 100x NA 0.9.
I have also seen yellow (and orange scales) look that the ones you have in the first picture but with lower NA.
May I ask how you light the subject?
Best regards

Re: Nikon plan apo 20x 0.75
Really nice experiment, just one thing. Increasing the distance between the tube lens and sensor also changes magnification, right? I am used to work with raynox on a bellows and it does that, change magnification as you increase/decrease the bellows extension. So, with that 300mm tube lens plus 80...

Re: Nikon plan apo 20x 0.75
Nikon plan apo 20/ 0.75 Nikon 300 mm tube lens and 8 cm extra distance between tube lens and sensor (compensating variation). Diffused led. The short WD distance made lighting troublesome, - I had to adjust the colours a little more than usual in Adobe PS (saturation and more contrast in the blue ch...

Re: Nikon plan apo 20x 0.75
Thanks both Jörgen and Rik. Increasing the tube lens to sensor distance (actually focusing it closer than infinite), how it does affect the free working distance? I assume that it will be shorter than the nominal 1mm, am I right? Jörgen, any chance to view your tests at full resolution? Pau That is...

Re: Nikon plan apo 20x 0.75
Hi Pau
No formula - more trial and error with combinations of tubes with fixed lengths, My best guess from the distances I did test is that optimum might be a little shorter.

Re: Nikon plan apo 20x 0.75
Thanks RB To follow up on compenasting variation with the Nikon plan apo 20x / 0.75 I did a series of pictures showing the difference between 1) a coverslip attached to the objective, 2) no coverslip and 3) no coverslip but 86 mm extra distance between sensor and tube lens - compensating variation: ...

Re: Tic
Thanks for the nice comments! I pulled the stereo image into StereoPhoto Maker and blew it up so I could see all the details. The translucency showing structures on multiple levels comes through wonderfully. --Rik Yes - For translucent subjects like this it is realy worth the effort making stereo pi...
