What is the opposite of a "eureka" moment?
Perhaps when you realise you are doing something completely wrong. All of the planets had aligned to provide what should have been a perfect photography opportunity for me at the weekend. I had a new uwa lens to try out (Tamron 11-18), the trees and other vegetation are very green, it was hot, sunny and bright, and I had a one hour pass to "go and play with my toys" - all perfect to try and grab an IR shot or three. Found a good location; very green trees, big historic building, blue sky, and a river. I carefully took some shots with the IR filter in place. Excitedly I took these home but, when reviewing on the computer, it dawned on me I was getting no IR effect, just very red images. Doh, and double doh! (I think the Doc suggested that this was happening with my last supposed IR picture.)
A google based investigation has ensued. I think where I am going wrong is white balance. It seems that you need a very low WB value for those "everything green is bright white" shots. It would also seem after reading other sites (one of them a Canon forum, sorry Doc ) that I should have made a custom WB shot (with IR filter in place) of well sun-lit green grass and then used this custome WB setting for my subsequent shots.
Would any of the IR Jedi here care to share a view?

Re: IR Woes, and Dohs
Armen loves to process IR shots in color. I am more conservative. I always process them in B&W.
I tried with colors, but somehow don't like it.
If you care to know anyway, I'll ask Armen to explain step-by-step processing in color.

Re: IR Woes, and Dohs
Hi Doc - any advice would be welcome. When you process them in B&W do you have to do anything with the WB setting before hand?

Just convert to Grayscale in ACR, or try to play with Hue/Saturation/Luminance.
Re: IR Woes, and Dohs
Here are some attempts. I have added the sepia tone. All with A700 + Tamron 11-18 + Cokin 007 IR Filter

Make them a bit darker and add some evil music, and you've got the start of a good thriller!

Hehehe - good point Dusty - I suppose they do look a bit gothic.
Still waiting for more clear, hot days for furthert IR experiments - it has been too cloudy recently, and now we have rain .
