Pai seh leh.... I also not master at IR photography.. just starting only.
:embrass:
From what I learnt so far, whether or not you get colours in your IR pics depends on the camera used, the IR filters used and whether or not you used a Custom White Balance when taking the pics.
I presume you are using 300D and Hoya R72 filter. If 300D is like the 10D, the IR images should have colours that are processible. Your pic however looked to be quite close to B&W. Did you do a CWB or did you 'Autocolor' it away in Photoshop? The top part of the sky could be black because it was cloudless but the lower part should show some red before channel swap and blue after channel swap because it looked like there were clouds there.
If the original image was indeed lacking in colour, one thing you can do is to increase the colour saturation either before or after you do the channel swap. You should also do Level adjustments as well.
Try the post processing again and see if it could be improved. Or you can send me the original file and I can try it out myself. The pic you posted is too small to work on without causing a lot of jpeg artifacts. Don't know if the CS forum allows members to see each other's email address or not. Mine was not set to hide but if you can't send to me for some reason and want to, let me know and I'll pm you the address.
