Re: Galanthus

Thank you! It's really nice to see how well the lens works on this sensor - I'm just wondering whether I could reduce the size of the setup, take the lens from a bellows to a... hm... helicoid? Hello, Not really. The helicoid usually needs additional support as it can't carry much on its own. Or ra...

Re: Shooting flies

Hello Gedaliah,
I have had little success so far with bathing flies in any liquids,
so I now clean them with air (bellows) and a brush.

Re: AstrHori 25mm f/2.8 2x-5x full-frame macro lens

I do find that the Mitu 7.5x pushed down on a good 150-135mm tube lens is significantly better than the Laowa at around 4.5x to 5x, and I sometimes use that For 5x I use Mitu 10x with EF 100L Macro. For 2.5x Mitu 5x and EF100L Macro. The USM motor of this macro lens has very small steps and a very ...

Re: ultra macro suggestions beyond 10x -- cheaper but ok objectives to play with? Sony aps-c

Hello everyone,
I have a few LU Plans, 20x is also included.
These lenses are great, but they produce a lot of CA,
which can be easily removed with software.
Unfortunately, these lenses are no longer given away
for almost free when I bought them.

Re: AstrHori 25mm f/2.8 2x-5x full-frame macro lens

I sure hope someone trustworthy and capable tests this very important lens.....these two lenses (AstrHori and Laowa) are unique for macro work and one of them should be in the toolbox of almost any macro photographer. Which one? Curious macro photographers want to know! Hello Lou, I don't have eith...

Re: High resolution sensors to measure mechanical position & movement

Hello Espresso,

I measure small distances with Zerene. It is very good for my requirements.

Re: kitchen ant

Hello Rik,
Thanks for the hint!
So far I have split Edge to two windows and opened the thread twice and then scrolled to the same places,
then zoomed in and looked at the two neighbouring images in the middle.

Re: kitchen ant

Hello Rik,
Fantastic documentation, great photos!
I've been putting off reviewing this thread because in order to see the stereo pairs,
I have to swap sides of images for the parallel view :-)

The removal looks good to me. Did you do it with the dust mask, or some sort of post-processing?

Hello Rik,
Post-processing, because in this case it was much less time consuming :-)

Re: some scales

These came out very nice! One small issue: I'm distracted by that dust trail that looks like a dark fiber sticking from front to back, below-left of image center. I don't know any good way to retouch those out of a stereo/rocking sequence, but they can be addressed effectively by building an approp...
