My camera is full spectrum converted, but this type of photography can be done on a *suitable* unconverted camera needing just an infrared filter, but the exposure times can become very, very long - check google for info. I put the appropriate (visible only or IR) filter on the front depending on what I'm doing and then take the pic as normal (with normal exposure times) using the viewscreen. If IR, then in photoshop I need to do a channel swap to give blue rather than orange/brown skies. Then, depending on the filter used, how much infrared is being reflected and the custom white balance used for the picture (extremely extremely important!) the colour of the leaves will range from white to yellow. Photoshop hue adjustments can also then be applied if warranted (eg to give a little more warmth to a photograph). Hope this is helpful.
Thanks, I had a little play with a filter but like you said very long exposures so even on what seemed a calm day the trees were blurry. I also used an 860nm so that would of made it worse. I played around with the red and bue channel swap but didn't get anything worth posting, oh and I used a normal shot as the custom white balance, heard that was a good why to get it right. I've got a 720 on it's way so we'll see how that goes. Thanks for taking time to reply Cheers Daven
For infrared, I've 590, 665, 720, 850, 950 and 1000nm filters. Not tried the 850 or 950 yet. Everything above 720 will be effectively only black and white with nearly no 'colour' information so that'll be why channel swapping on the 860 didn't help. So yes, with the 720 you'll actually get a blue sky after channel swap. Personally I'm preferring the 590 and 665 to the 720 as it seems to give very cold images though it's good for the 'pure-white-leaves-wintry-scenes'. Entirely depends on what you're after. Finding a good white balance for this seems to basically be 'find what works best for you.' For the 720 and higher, find a patch of brightly lit (green! Not yellow, or cut to the roots!) grass or leaves.. Anything that reflects a lot of IR seems to work. A lot of debate seems to exist for what's best for the shorter wavelengths (hot grey tarmac is sometimes suggested rather than the grass). Basically have a play and see what happens. Hope this helps. I'm new to it myself. Good luck!
