I recently picked up a 720 nm IR filter, and have been experimenting with it. My biggest problem is exposure. Just how red are my pics supposed to be (pre-processing)?
So far, as an example, on sunny days, I can get satisfactory (to me, anyway) photos using my 55-200mm of 1/2, 0.4, 0.3, 1/4, & 1/5 sec, @F5.6, 115 mm. On cloudy days I seem to be upping that to around 1-3 seconds.
Anyone else trying IR that can share some information?

Finally managed to upload the pics.
They are in the "I am NOT a photographer ... I just like takin' pictures." user photo album.

Hi all,
I'm currently in Changchun, China. Went to the July 22 total solar eclipse in Hangzhou with a Pentax K-1000, last year. The developer used old chemicals and totally ruined my photos. I have shot other eclipses with good results, and I can recognize what underdeveloped film looks like (some of the original emulsion was still on the negs), so I decided to venture into DSLR photography for the control I can have over the final image results.
Boy, is the learning curve ever steep!! I've shot night scenes on film before, but tonights results with the new K-x were, in my mind, rather interesting. I can't say disappointing because every picture has something interesting that we didn't expect, LOL (IMHO).
I'm getting some yellow in my images. WB was set on auto. I suspect it was caused by the streetlights. They were shot with the kit 18-55 mm. Exposures were between 1 and 6 seconds at f/3.5 - f/8.
I've got four images, but I can't upload the pics because I have to solve this "security token" problem first. Anyone got any advice as to how to get rid of the "yellow snow"? (Please, please, please don't tell me to go potty before I leave the house :D )
Thanks in advance
Chris
