hi there peeps,

i've been mucking about with the cokin infrared filter on the front of my lenses and have worked out that i need to be in the range of 5 or 6 stops over exposing the cameras own metering and have been setting the custom white balance to a full frame of grass. i'm very happy with some of my first proper attempts at colour pictures but most pictures i've found on flickr have blue sky's compared to my burning red? is there something i've done slightly wrong or is my process wrong,

all i've done here is adjust levels and straightened the horizon other then that it is just straight off the camera.

if anyone can help or add any insight i would be ever so greatful
 
thank you ever so much for your helpful and quick responses seems to do the trick quite nicely,

just need to get some proper photos taken now and not just out of my window
 
Def far better, although the whites could do with being a bit 'whiter'....

If you are letting only infrared light in there isn't any colour from the visible light spectrum in the photo.

Infrared photography isn't true infrared, it's near infrared, there is still some of the visible specturm included.

The focal point for IR is different than with regular photography, which is why companies that mod cameras to shoot in IR (should) adjust the focus of the body, usually to work with a particular lens.
 
i've noticed that my 28mm f1.8 and my 50mm f1.4 have the infrared marks on there for focus which does come in handy

i went out yesterday in the lovely sun and did some more which i have put up in the other forum if you would like to c&C them, link link
 
I fitted a 850nm filter in place of the filter on the sensor in my 300D, just lets IR through full mono images of IR goodness, focus is ok too as I put some packing pieces in to adjust it. A 715nm filter could also be fitted to allow some visible light through to give you the blue skies.

Exposure times are the same as a normal camera, only thing you have to change is the white balance.
