hi all, i got a cheap ir filter to try out so i thought i would let you know how i got on with it. IR images look unusual as grass and leaves reflect ir light well and end up almost white in shots. The filter i got is a square filter that fits a lee holder and it is black to the eye so no visible light gets through.
I found the filter i got needs an exposure of 30 to 60 seconds in sunlight similar to a big stopper and i used the histogram showing each colour channel to get the best result. The main issue i found was focus as ir light focuses differently to visible light and you cant tell if its focused correctly until after you take the shots.
Here is the result i think i set the focus for this shot at 10 meters

The shots come out of camera with a red cast so post processing is a matter of adjusting the colour channels to suit and you can got some interesting effects it found increasing the green and reducing blue channel worked well. Personally i prefered the mono look.
let me know what you think and if anyone else has any ir shots please add them them
