Hi Marek,

Excellent picture, it is similar to fractal.

Personally I do really like those colours ans shapes presented on picture.

I want to ask You about retarder. Could You explain me what does it mean. if You prefer, please answer me in polish.

All your photos are amazing.

By the way, I want to to tell You, few years ago I read articles in Photography magazines, which had been written by You. Under influence of those articles I have been starting interested microscopy. Last year I bought microscope and started realise my new passion. So if You enjoy picture of parched Chaoborus which I made, It is your fault
Laughing Laughing

Of course I am joking.

I congratulate Your photos.

All the best

I recently came across some descriptions/illustrations which are nice for retarders, here https://pubs.geoscienceworld.org/eurjmin/article/25/1/5/69671/a-revised-michel-levy-interference-colour-chart

Polarising materials are birefringent, which WIkipedia will explain better than me! The two rays of light which emerge interfere and give you a diffraction pattern. The bands of colours repeat, which you see on a Michel Lévy chart, at whole (1,2,3 etc) wavelength differences in path length through the material. They're often "nicer" if you can delay one of the rays, to get to the "Second order" part of the chart. The
quarter, half and full "wave plates", slow light by that fraction of a 550nm wavelength.
You can use materials like cellophane or "Sellotape" in the thickness you want (by combining) to get the best effect. CD wrappers work well.
The chart which shows that well I think, is this one (though the numbers aren't directly very useful). A traditional Michel-Lévy chart is a section through this illustration:


As you probably know the technique is used for diagnostic purposes with geology specimens. There are some nice examples here which show the effect of changing the retardation: http://www.microscopy-uk.org.uk/mag/indexmag.html?http://www.microscopy-uk.org.uk/mag/artjan05/bjcomp.html

If you can arrange to rotate, or tilt, the "wave-plate" you can adjust the colours easily.


Oh - I believe callous remover is often salicylic acid.

Thak you all for comments !

MASZEK, I am proud and happy that my articles caused you to start taking photographs using a microscope. Your Chaoborus details are very, very good !

If about the retarder, Chris has explained it very good. The another name which you can use for the reatrder is compensator (gdy kto? pyta mnie, po co to i jak to dzia?a, to najkrócej odpowiadam, ?e retarder modyfikuje ?wiat?o spolaryzowane w taki sposób, ?e uzyskujemy niemal nieograniczon? palet? barw).
By the way, welcome to this excellent forum. I had a long break but I think I will be looking here more often Smile

What is your set for taking micrographs (microscope, objectives, camera) ?

Good luck in your new pasion !

Hello,

Marek, Thank You very much for your fast feedback. Tell me please, if I have problem with something, may I ask You in polish language. Sometimes there is difficult to use english technical nomenclature to describe the problem. I have noticed your long break on this forum, though my presence is short. Your photos are really masterpiece and there is a big lack of it. I personally think You are the seminal figure in develop photography by microscope in Poland. By the way Jacek is very good as well


ChrisR, Thank You very much for your answer. Great job. Links as well as diagram is very usefull and I think it will be helpfull for me. Thank You very much as well for your explanation and description of diagram.

Best regards,

MASZEK, I think not too many people at this forum know Polish Wink
So, I think we should realize our conversations in English, at least here.

I think the best way for our conversations in Polish can be Messenger or the e-mails Smile

Very unusual and beautiful image. It made me think of late 19th century paintings.


Regards,

Walter
