IR on the CHEAP

[andy153]

Hi Don, The filter that was installed is a 720 nm, in the camera and on download they all show the magenta cast. At the moment my white balance is set to auto. This is the original of Bodnant Hall

At last Andy, welcome to the club. "Bodhall" is what IR is all about, great sky.

I will now be absent for a couple of weeks. Holidays in the Carribean, perfect weather for IR, but it's doubtful the IR camera will be with me due to weight constraints.

Cheers Andy,

I have saved it so I can compare side by side with a Hoya R72 shot. Yours has quite a different tint to my film filter ones taken on auto WB.

Normal rules apply here. Get a bit of kit and the weather changes to limit your possibilities to play. So I have no good sunshine shots with the R72 filter.

Still we are on sun, sun, sun for the next few days.

Thanks Harry, enjoy a well earned break, I will be looking forward to your contributions on your return - enjoy !

Have a great holiday Harry.

There should be a fair bit for you to catch up with on your return.

Thanks, will do, My wife reckons she can manage the IR camera, so maybe I'll come back with a few IR shots.

Harry

have just been playing around with "One to Back Process"
There are quite a few alternate methods with this one. All of which IMO are well worth pursuing.

I've attached an old colour pic converted to infra red, just out of interest.It's another way of looking at the problem.I used to shoot Kodak and Konica IR in the old days when we got our hands smelly in the darkroom.

I tried a similar thing last year but cannot remember, or find info on, the steps I took. Hence I got involved in the film filter bit at the start of this thread.

It may help others if you can post a processing step by step, as I do not recall anyone doing this in the Digital Darkroom Forum.

Well I ordered a screw in filter to have a go on the cheap, unfortunately the 30D clearly has a very strong internal IR filter - without the filter I was getting 1/400th at f8, with the filter on I needed to push the shutter speed out to a ridiculous 25 seconds to anything. Even then the files don't have that IR feel, I think with the long shutter speed I'm also getting some visable light contamination. I think I now have two choices, get the camera converted or forget about IR for now...

As an aside has anyone tried the Sigma SD14? It has an IR filter just behind the lens mount that can easily be removed and replaced, it could make IR much easier... a good solution if you're a Sigma user.

For those who are interested in doing this without conversion here is a link to a set of Photoshop Actions that recreate IR effects - known a "faux or false infrared" This link comes from Steve's Digicams and one of them is an action where you can tweek the results yourself. There is also a pdf guide to how it all works.
