  • Tutorial Infrared false colour - some processing techniques

    you. This is what another one that does the same thing from Kolari Vision; download and install as an Action in PS for repeat use. One click in the Actions panel will then swap your red/blue channels for you.




    Once cyans are sorted, you can then play with the other colour hues. I find that on this particular filter only the reds really have any effect, so I tend to stick to adjusting just that. You can see the effects by taking the red hues up and down the scale:










    Stages of blending






    Save As a final blended version when happy.




    Channel swapped and opened in Viveza




    After some patient work, final colour adjusted image




    Another example: Processed for colour, then converted to B&W and selected tree-colour-only brought back in Silver Efex Pro.

    Re: Infrared false colour - some processing techniques

    Hi there Margaret!

    Many thanks for showing us your methods, and for the important info about ps elements not having channel swap capability - I thought it was just me that couldn't find it! I will have to find out if there is a free image editor which can channel swap on a tiff file before I bring it into elements for a final tinker. Right now I'm just waiting for some foliage on the trees and some sun in the sky!

    Cheers,

    Ralph.

      Yes they do - you're 'It'!

      Great tutorial and images. I'm tempted to give it a try.

        Hi Ralph - I can't speak first hand, but there's apparently some kind of plug-in for Elements that then allows channel swapping. See here for some Elements Plus information.

        May be worth a look

            Margaret this is the internet, it's FULL off experts!
            Many are self proclaimed with little or no knowledge of the subject which does make it harder to find the good ones.

            I personally do very limited processing on my IR shots, reading your comprehensive tips might get me doing a bit more!

            There are some tips on the latest Infra red forum http://global-infrared.freeforums.net/, and I think I've seen some by InfraEdd, Kolari-vision, lifepixel... too. But I don't think any are as comprehensive as yours.

                Thanks Mike, I hadn't come across that particular forum, I'll have a browse. Maybe I'll find An Expert!!

                  Thanks Margaret. Lots of food for thought there, well explained.

                    It's only been around a few months, formed when the previous one (Which was itself created to replace another overcome with spam...) suddenly disappeared, just as I was preparing a session for our local workshop. Fortunately I had the email adress of one of the moderators so was able to find the new one quickly.
                    After an initial burst it's been getting rather quieter lately - perhaps due to increased light giving a chance to SHOOT rather than type about it.

                    Only about 20 members as yet, but I think from the user names at least 3 of those who have yet to post are fairly experienced, and I've seen some interesting/useful stuff from several of the active members.
