Sunrise on Sierra Blanca - two views.

First shot has a rosier, brighter sky because the polarizer is not doing much filtering of the scattered sunlight.

Second shot has a darker sky because the polarizer was rotated for max filtering of scattered sunlight. This makes the sunlight summit stand out more starkly.

Which photo do you prefer?

Rosy sunrise on the summit of Sierra Blanca. The sky is also rosy because the polarizer is not filtering out the scattered sunlight. The rest of the foreground is cold blue and covered in snow.The same view, seconds later, but the polarizer has been rotated to filter out the scattered sunlight...making the sky darker. This makes the sunlight on the summit more striking.

Sierra Blanca peak shows max green in late monsoon season.

It was a very transparent morning, and the polarizer really cut through what little haze was in the air for the 30-mile view of this mountain in southern New Mexico.

Even the terrain above the tree line is tinted green.

New day on the walk ||
This day on the Isle of Jersey, a #walk from the "jardin d'Olivet" for a first pause at "Boulet Bay".
This part of the walk, as you can see on this #analogphotography is very great because the footpath starts at the top of the bay to ended just in front of the sea.
#Film was a #kodakportra400 with a #Bessaflex TM. Lens was a #SMC #takumar 50mm f1.4. Exposure parameters was f8 at 1/500 with #polarizer filter.

Return to a place where crows gather part. 2 || My second #analogphotography of "La Corbière". Just in time for changing film. #Film was a #kodakportra400 with a #Bessaflex TM. Lens was a #SMC #takumar 50mm f1.4. Exposure parameters was f11 at 1/125 with #polarizer filter.

A photographic study in backlit trees.

Distant conifers are dark.

Foreground is oak...waxy leaves produce annoying glare.

In the middle are aspen...looking best with sunlight behind them.

Or put the sun at 90 degrees and use a polarizer to darken the blue sky. That helps make the aspen pop.

Stresses Revealed With A Polariscope

There are a lot of ways that stresses can show up, at least when discussing materials science. Cracks in concrete are a common enough example, but any catastrophic failure in a material is often attributable to some stress that couldn't be withstood. If you're interested in viewing those stresses before they result in damage to the underlying material, take a look at this DIY polariscope which can view internal stresses in glass and other clear objects.

The polariscope takes its name from the fact that it uses polarized light to view the internal structure of a transparent object such as glass. When the polarized light passes through glass in a certain way, the stresses show up as lighter areas thanks to the stressed glass bending the light back into view. This one is constructed with a polarizing filter placed in front of an LCD screen set to display a completely white image. When glass is placed between the screen and the filter no light is seen through the polariscope unless there are stresses in the glass. Even placing a force on an otherwise un-stressed glass tube can show this effect, and [Advanced Tinkering], this project's creator, has several other creations which show this effect in striking detail.

The effect can also be observed as colored areas in other plastic materials as well. It's an interesting tool which can help anyone who frequently works with glass, but it's also interesting on its own to see clues left behind from the manufacturing process of various household items. We've seen some other investigative methods for determining how other household items are mass produced as well, like this project which breaks down the injection molding process.
