Hi,
Have been trying out in paintshop pro making some of my images into infrared ones digitally. Have put them all together into a slideshow in lightroom. Pictures were taken on various cameras,including a K10d, even some on a 3mb compact years and years ago! Just wondering about thoughts on them, it quite interests me. Will now probably be purchasing an infrared filter for my digital SLR.
Hope this is allowed, but here is link

If you had not mentioned Infrared anywhere, I would have said that they were B&W images.

EG: Most IR shots of grass, trees, etc shows the greens as white.

Your images, good though they are, don't quite portray that.

Brian, I've yet to see s digitally processed visible light shot that looks truely convincing as IR. It similar to taking the RED channel & processing it to give you a full colour image.
The skies in your Pseudo infrared images are all very pale - typically IR skies are dark with highly contrasting clouds.

Go ahead & get a filter, they're available very cheap these days, and if you don't mind long exposures you should be able to capture real IR images. I suspect the K10d will have similar IR sensitivity to the K100d which can be handheld for IR on hot days with a fast lens.

Nik Software's silver Efex pro plugin has red, yellow orange, green and blue filters to apply on the B&W conversion. the green filter would give greens as white.

Quite handy feature even if you're not purposely trying to emulate infrared.


Personally I can't get excited about IR photos. YO ucan get similar just converting to B&W anyway

Thanks for info and comments. Think one problem was in quite a few of those shots they were taken in a very overcast Isle of Skye. Was a beautiful day when we arrived all those years ago, then about 4 hours later it clouded over and we had horizontal rain for most of the family holiday (in August!)
Just tried it on a very cloudy blue sky, but as mentioned, almost impossible to achieve, for me at least.
Just ordered the infrared filter, good price online

i did this with Hoya R72 ir filter, you need to set a custom white balance, then do some colour channel swapping to keep the blue sky. fortunately there are a lot of very good tutorials on you tube you can use to guide you. hope to get it out on my DA15 , waiting for some greenery to appear most of the trees are only just starting to show

As someone who takes a lot of infrared images, I would say that if you want to shoot IR then get an IR converted camera, or use an IR filter on your existing camera. Anything else is a pale imitation.
