Thanks for link to tutorial
Adjustment looks easy but i must have good picture im afraid.

Im just back with new pictures but effect is same. Red everywhere, green still isn't white. cant set proper white balance.

How bright it should be to take good picture?

Maybe lens?
im using pentax 18-135

The filter IS red so the image will become red. You can get a less red white balance in the camera but it will still be a little red. You need to do as they state in the tutorial I posted and switch the red and blue channel and then get rid of the blue tint with a white balance tool.

Ohh sorry, misunderstanding.
I know, picture have to be red, due to colour of filter.
I mean - cannot set properly wb in camera raw.
Pictures in tutorial were brown, and green was white before any ingerention.

I camera raw, use white balance tool to get as close as you can by picking something that you want to be white. Go into photoshop, switch channels, flatten the image and use camera raw plug in if you have CS, if not save as tiff and open in camera raw and use white balance tool again to get even closer. Good luck. Some images won´t be good for this while some are great. Also try to make them black and white.

Good early attempt. This is good.

Not all exposures lend themselves to swapped channel processing. I find it easier to maintain white trees without swapped channels. I'd try a few of those first. That's what I did.

I'd reload your raw image and try it as I describe below:

On non swapped images, I start with the raw image and on conversion into PS, I play a bit with the color balance to darken the sky. Then I convert to B&W via the PS function that allows the lightening and darkening individual colors.
I used that for this image:


I also do channel swap, but I find that much harder. It takes much more time. Here is an example of that. It was not an early attempt of mine. Here is an example:


Both of my images are from PWD year ago.

You should make in camera White balance - it has much wider tempreture range than photoshop raw. Just search for Manual Whate balance for IR. or use software which although use extendet tempreture range such as "Phase one capture one 7". There are although some plugins for camera raw that will do, but personaly, Phase one is much better...) So get a free trial...
