Re: Zodiac Moth Scales

Hi Dan

"100x, epi-illumination" unfortunately says little about the lens.
Nevertheless, it should be possible to darken a little bit on one side of the light path.

Good luck

Re: Zodiac Moth Scales

Hi Dan

I really like your pictures.
Which 100x lens do you use?

Your pictures look a bit flat.
I assume that your lighting is all around and even, without shadows.
With lateral light you get soft shadows, the object gains depth and the visible resolution is higher.

Re: Papilio ulysses

Hallo Lothar

Thanks
The working distance is about 4.9mm.
The corners on the full format are grudgingly acceptable.

Re: Alien

Hola Macrero

I like your way of lighting very much, masterly.
Have you shown your light setup anywhere yet?
Although the high quality of your pictures is not only due to the light setup.
Your editing is also exemplary.

Re: Aliens among us

Hallo Lothar

A beautiful little foot!
I especially like the partly amber-colored (Bernstein) hair.
Light, stack and processing are of the finest.

Re: Sternotomis virescens (F)

Hola Macrero I measure the resolution of the objectives with the Zeiss resolution test object 3000, it goes up to 3000 LP/mm and is therefore also suitable for microscope objectives with a high aperture, color edges caused by CA can also be judged very well. Decisive for me as a photographer is the ...

Re: Sternotomis virescens (F)

"Now I am in search of a good lens/es for the 1-3.5X range." Hola Macrero One of the best lenses at full format from 1:4 to 4:1 is the HR Digaron Macro 105mm f/5.6. It is accordingly expensive, about 5000 US dollars. I use the Rodenstock APO-Rodagon N 50mm, 1:2.8 in retro. The resolution is high, we...

Re: Apertur-Stacking

Hello John

It can also be done with automatic exposure, both by changing the exposure time and by changing the sensitivity (ISO).
Actually it is very simple and clean.

Re: Palomena prasina eggs and the hatched nymphs

Hello Mike

The nymphs react to shock, they remain still.
Between each picture of the stack series, I lightly tapped the surface with tweezers.
In this way they remained calm.
