It just occured to me, that manufacurers in the camera world must have come up with solutions to the problem of image degradation created by a 45 degr. glass sheet operating as a beamsplitter. Sony has developed a series of cameras, the Sony SRT models, where SRT stands for Single Lens Translucent (...

Exactly, Lou. In fact I thought of the same parallel because I also saw a lot of ant lion cones in the sand on the same island of Laesoe. One of only three small locations in Denmark with this insect.

Thanks to all for looking and commenting! Lou, I have only observed the larvae holes once before in my life and there were also several dozens of holes located in a small area. I doubt we are talking about colonies in the strict sence where the individuals mutually benefit from living close to nabou...

I wrote down some thoughts about cube shaped beamsplitters. I happened to poste it in the thread just mentioned ealier about coaxial lighting.
If interested you can read it here . No reason to repeat myself.

I am in doubt how relevant this is, but I noticed that your beamsplitter consists of a thin sheet of glass. Some professional manufactured beamsplitters are built by connecting two glass prisms resulting in a cube shaped splitter with a 45 degrees boundary crossing the cube corner to corner. Se this...

The Portrait is very impressive!

Thanks Robert
I appreciate your feed back!

On my holliday travel to the Danish island Laesoe I was walking along a sandy track looking for photography objects when I suddenly found this big fly sitting on the ground. Very carefully I got closer and managed to get my picture without scaring it. http://www.photomacrography.net/forum/userpix/55...

But the stepped shape is not the normal shape of a shutter blade or "curtain". Would the edge of the shutter blade placed close to the sensor not appear rather sharp? I think it looks more like a mirror attached to a metal frame. Further more it is positioned in the upper edge of the (upside-down) p...

For macro photography you need to be close to the wall. That means you only need a small window. You could cut a hole in the plastic wall and glue a piece of thin glass of high optical quality. It could be a UV filter for a camera lens or a big slide for microscopy (I think they are available in 4x4...

Thank you! The surface is in fact a little cork cube bought as a refrigerator door magnet. It is made from a lot of small cork pieces glued together under pressure. In real life it is a little darker than the picture. But to make shape of the black animal more visible I adjusted the histogram toward...

A rainy afternoon spent in the macro studio. I have a working set-up with nice possibilities for adjusting the light. And I am the lycky new owner of an old Carl Zeiss stereo microscope. Time for going into extreme macro insect photography. The next challenge turns out to be preparing the insects. T...

It will be interesting to hear about your experiments.

A very nice and interesting picture.
Grasses can be so beatiful.

Reading my former post again I realize that it is perhaps too academic. In the real world your 3D printer will not be able to make a surface camparable to an optical smooth mirror. There will be more than a little scattered light from the forward directed surfaces. Luckily thanks to the smart design...
