The Development of a Fixed Polarizing Filter

Appreciate the legitimate comments, suggestions and questions BOB.

Q: It's a polarizing material and not just an amber-tint plastic?

A: it is unclear as to what this material is, our company was using sheets of this in an experiments. it looks to be a a dark tinted plastic/resin material and it does have bubble and flaws. So It's not amber in color.

Q: There's something odd going on with the green leaves in the upper left of the first image. Can't tell if it's from the filter or the processing.

A: There's zero processing here. the image is and how it was taken on that day. The leave simply ran together because of a breeze creating mass of blurred colors. Some of the trees did not have any fall colors.

Q: The second image, I like the effect but the image is covered with some sort of texture. Compression artifacts?

A: The only thing done to this daylight image was a color conversion to black and white.

Q: I'd be interested in seeing side-by-side with and without filter images.

A: This is one thing I didn't even think about doing while taking these images. The wife sat in the car while I walked though a field to get to the best position in order tot ake the shot. Also, One other thing I negated is to see what would happen with two filters in the Cokin mount. This is also something I'm going to keep in mind on the next outing.

Q: You said it's a plastic/resin material. You're confident that it's scratch-resistant and durable enough for use as a camera filter?

A: No, it's not scratch resistant, But seems to be durable enough over the last year if one takes time to care for it. I'm hoping to hear feed back from my volunteers about this.

Months ago I sent what was left of the material to a millwright to have them cut the material into the 85mm x 100mm panels. The first couple of panels I did myself but left sharp edges and screwy corners. The batch arrived a few weeks afterward. I wasn't pleased with their craftsman ship. So I'm looking to locate another shop to cut the remaining panels.

One other thing, since posting this I've not been getting any positive or plausible questions about what I'm doing and because I'm switching formats I may drop the subject of offering this filter to the public. One my volunteer's reviews may help me decide if this something I should continue. I guess this will remain one of those tricks I'll have to keep to myself. But I will be testing this filter with any new/used camera I'll acquire over the next few months. The holga is going to be another experiment of mine.
