IR on the CHEAP

[postcardcv]

The shot was taken in jpg using custom white balance and -2/3rd ev comp - not much PP done, just a small adjustment in contrast and brightness, then resized and a dash of USM.

I was told that the camera has a Hoya R72 fitted in place of the hot mirror but looking at my shots I suspect it's a slightly stronger one. I'll have a play shooting RAW in the next few days and see what it's really seeing.

Very interesting Peter, as you can see from my post number 71 in this thread, my pictures all come out with a magenta cast. My filter is a 720 nm which it the high end of the R72 - almost black. How did you set your custom WB? I'm still playing with mine but always get magenta so far. Andy

I took a shot of grass in direct sunlight (using auto WB) and set my custom white balance from that, it seems to have worked well enough. From what I've read this is the commonest way of doing it, though you can also get nice results is you use a blue sky to set it from.

Thanks for that, it's what I'm using as well, needs more play.

I've just been playing with the sample images that I got from ACS using a converted D200 - the attached image shows the difference in the auto and custom (again using grass) white balances on that converted camera.

Hi Peter, I think I have finally sorted my preset WB - I suppose as the camera is converted for IR I will seldom need to change it. Below is the straight from camera followed by a twitch of RBG. This is a lot easier now.

Just got back from Cuba, far to hot to bother much with photography, but here's one take from the veranda of my holiday villa.

WB was my custom one set in England by photographing green grass.

Normal P&P plus a little tweaking.

Excellent Harry, welcome home - trust you had a good time.

As the title of this thread is IR on the cheap, here is a link to a web page that has a Photoshop Action for FAUX INFRARED - ie false infrared - and you cannot get cheaper than that - use your own pics and treat them in post processing, no gadgets - just your imagination. This site has a lot of Actions for Photoshop and they are worth learning how to use as they save you from re-inventing the wheel each time. This is an excellent site and has actions for many different versions of Photoshop - http://www.thelightsrightstudio.com/TLRFauxInfrared.htm
Have fun and enjoy playing - the only limit is your imagination.

Looks interesting Andy. Thanks for posting.

A bit busy doing some NX tutorials at the moment but I will check it out when I have done.
