Micro Photography in Polarized Light - Magnified Photography
Micro or magnified photography has long been used in photography. The crystallization of elements is a special form that can create beautiful structures and rich colors.
Polarized light is a playground for preserving old photographic knowledge.

What is polarized light
Light is scattered, but can also be directed using a polarizing filter if you place it in front of the light source. If you then attach a second polarizing filter rotated 90°, the scattered lights cancel each other out and you get a black surface. Elements that deflect light now become particularly well and colorfully visible. Some microscopes also have the polarizing function. Especially in the industrial sector, this can be used, for example, to detect stresses in materials.
The technique can also be used to eliminate reflections. For this, you also need 2 polarizing filters. In this case, however, not as transmitted light, but as incident light. The effect is astonishing, as it allows photos that would otherwise only be possible under perfect studio conditions.
Smallest scales under 1 mm and Stacking
In pure photography, the limit is reached at 5:1, and even then nothing should wobble. Of course, more is possible, but then you absolutely need a microscope objective, preferably a Mototoyo 50 or 100x or comparable from Zeiss and Co. An automatic macro rail with an extremely small step size would also be great. Here I'm eyeing the
which I discovered on an Instagram channel:https://www.instagram.com/medienbunker_produktion/
But it's also fun with a magnification ratio of 3:1 and since the microscope slides are flat, you don't necessarily have to stack. Nevertheless, the height of some crystals should not be underestimated, so I additionally sharpen the images. This works best with Topaz Sharpen AI.
What do you need for this?
I use the following:
- Canon mp-e 65mm magnified lens 1:1 - 5:1 with step-up rings to 82mm polarizing filter
- Camera with macro rail pointed downwards
- Lupine Betty 2 for light from below with step-up ring for 82mm polarizing filter
- 2x 82mm polarizing filters (camera and flashlight)
- Bresser microscope slides (or other glass plates, reusable)
- 5-10 spoons and a lighter for mixing and heating the ingredients
- Pipette for ISO propanol, water etc. for better dosing
- Toothpicks as spacers for microscope slides on the polarizing filter
- Crystallizing substances, which are best found on the internet by searching for Micro Photography Polarized Light. These include B-Alanine, Vitamin C, Paracetamol, Aspirin, Sulfur, Baking Soda, Citric Acid, Copper Sulfate, Caffeine...

Basically, you can photograph many things with this setup, but polarized light really shines with certain substances.
You can mix almost anything with anything, and the results always turn out differently. Even with just one ingredient, many different motifs can be recognized. It is therefore a rather experimental type of photography that will be fun for a certain period of time.
My course participants are welcome to borrow everything they need for this. Beta Alanine, MSM, and co. are usually only available in larger containers, which are then never used up. All these substances also have an effect, e.g., as dietary supplements, laxatives, medication... I currently only use substances found in the household that are not toxic in small amounts.
