Kudos to Woligal for great use of her stress pattern technique- nice and elegant compositions as well!

Some years ago, I accidentally discovered this effect while shooting a commercial job for an optician/manufacturing company that produced prescription eyeglasses for optometrists' offices that outsource the crafting of lenses and frames. The assignment was to create photo murals for a background for a trade show display booth.
The "problem" did not occur, as was previously alluded to, on the glass lenses but on PLASTIC lenses of high quality, when a polarizing filter was used to deal with a few unwanted reflections the colour array appeared, much to my chagrin! I showed this to the client and he thought it would be great for the signage and graphics of the display- he LOVED it. I stopped cussing!
Since I have used this"effect" now and again for my food and beverage clients. But then came a little more magic! In my "why did I ever buy this drawer" I rediscovered a box of buried Cokin COLORED polarizing filters. The concept is to STACK them with a regular polarizer and change colour or to stack them with other coloured ones and more bizarre colours arise. Before the days of "sky replacement," I purchased them to enhance blah skies so instead of getting a blue blah sky, I got an orange, yellow or whatever one. After several unsuccessful experiments, I cast them into the drawer.
For the "anti-filter" cult, stacking filter is mortal sin bot it matters not because, in special effect, this does not seem to affect sharpness and aberrations are you friend! Well- this filter kit seems to be discontinued but there are loads of them on Ebay. I disinterred the filters, showed them to my lovely wife and said "I told you someday these will come in handy"
So here is where the fun starts: You can use a black background or transilluminate the plastic material on a lightbox or sheet of white Plexiglas for a high key effect. If you use a Speedlight as a lig source, you can place the coloured polarizer over the light, use a CPL filter on the camera and you will get a whole new colour array of plastic stress patterns.
More fun? These are pretty wild colours but if you pop in some textures, special effect apps, Topaz stuff in post-processing, play with saturation and contrast and sharpening tools, the various combination are endless. Great for abstract renditions as well. Works on plastic ice cubes in beverages.
Lately, one of my large food processing clients needed "I am now fully vaccinated 3x5 ID tag for its 1,000 employees access the country with a graphic on one side and the official document on the other. I created a shot for them- evidently, the disposable syringe is made of cheap plastic!
The old Cokin filters are not CIRCULAR polarizers but they do not seem to affect the AF system, although I can always manually focus and I set the exposure manually.
I think they are great tools for creating digital art and photography.

Always good to hear what we do in UHH can be used in the real world. Thanks for your thought process.

E.L.. Shapiro indeed, simple 8th-grade science offers great photo opportunities that few explore. Fascinating results and educational discussion.. that is what UHH is supposed to be about.
