IR filter
Posted: Sun Mar 02, 2008 2:13 pmI am trying to use a generic IR filter with my 350D... I can't seem to get any pictures that I can see. What am I doing wrong? Don't tell me it's the camera body 
Thanks

Posted: Sun Mar 02, 2008 4:56 pmTry adding +3 or 4 stops exposure compensation. Turn the metering mode to spot metering. Adjust your exposure to get a good histogram. Work from a tripod. Shoot at f11 or f16 and whatever shutterspeed the camera chooses.

Posted: Sun Mar 02, 2008 7:29 pmAs well as matt's suggestions you could help the colour cast a bit when you do get images you can see..
Take a photo- (it'll probably be pretty red) then use that image as your custom WB and you should get some nice useable colours, although you can still do B&W conversion in post processing.
Typically my exposures on a 400D with a Hoya R72 are around 1 second @ f8,iso 400. Obviously this varies according to how much direct sunlight is being captured. Just keep checking the dispaly and changing till you get it.
