Polarized Spider (+3)
Some time ago I wrote an article about a diy project how to easily use cross polarized light in your photos (for details see this post) but I din't try it that much in the fields. Now I made another polarizer diffuser for my on-camera flash an here are some results. I really like how the colors come out.
Fujinon 50/1.4 lens with extension tubes and polarizer filter.
Not so easy to shoot, since I had to stop down before shooting (around F8, don't look at the exif) and the viewfinder was really dark.
See some more shots in the comments, have a nice day!
