I took out my sigma 35-80, an ND4, and four polarizing filters today to try some ultra-long exposure photography. I elected for a ton of CPL filters because they allowed me to control the light levels, quality, and coloration in-lens for the shoot. Here are some photos.
f4, 30 seconds, and now in B&W:
f11, 30 seconds, and now in B&W:
f11, 30 seconds. I saved this for last because it exhibits why I chose multiple polarizing filters. Th blue color in the water was not because airplanes dump waste into the creek; instead, it was because the polarizing filters, when all turned in a certain way, removed all of the light spectrum except blue. So, adjusting them slightly away from that resulted in deep blue water while retaining fidelity in other colors. And now in B&W:
For this image I lightened the blues and cyans. Leaving them at the default settings made the water indistinguishable from the rocks, except for texture, and gave the image a very flat final appearance. In exchange, I darkened the greens and red, left the yellows slightly darker than mid-tone, and did nothing with the magentas since there were none.
One of the best parts of nature photography is what happens around you. First, a mother duck and ducklings swam up the creek. Faced with the choice of me or a dog, they decided to walk up the creekside across from me. They quaked a lot, to let me know they knew I was there. That was neat. But then a crawfish, and a big one, began climbing up the waterfall. By the time the third shot had finished being exposed and I got the filters off my lens, he'd been washed down the waterfall again. Oh well, maybe next time I'll get a photo of a big, bright red craw dad scaling wet rocks under (to him) a Niagra-like flow. _________________ http://www.youtube.com/user/hancockDavidM |
