Hi, has anyone tried this form of photography at all, I am struggling a little with my first attempts and limitations of the camera (Canon EOS300D).

The shot below I know has two problems, the light circle in the center of shot is an anomoly with IR and digital, take pics off centre and crop next time, also a BM drove past and caused the flares seen on the car, a minute later a minibus pulled up in front of car and spoilt the party. This pic is straight off camera only photoshop was resize and number plate.

Any comments, hints welcome, I would love to get a good IR photo.

Was the pic IR'd using PS or using an IR filter on the camera? If you push the channel mixer to the correct boundaries you can get pretty good results.

Example which was originally a plain colour photo taken on my 350D, tweaked with the channel mixer (Blue - 90%, Green +90%, Red +90%) to produce:

BTW, Nice motor, Shifty!

In addition to the above, I used to use an Ilford SFX filter (a now sadly discontinued 'friendly' IR film) on my Canon Powershot A40. This used to produce stunning IR photos with a bit of contrast tweaking, but more recent cameras I believe actually have an IR filter built it which tends to make IR photography a touch trickier.

Were you using a lenshood? I suspect the flare in the middle of the frame is a dust spec on the IR filter.

HTH.

Hi Rob

I used a R72 IR filter on the camera.

I have read about the flare being a problem with digital somewere, as the CCD has an IR filter directly on its surface, sensor and lens are clean.

No lens hood, sun was behind me, the few white marks are a passing car, this can be seen on the original at its full size, a minibus and a phone call from work prevented further shots.

I have only PS Elements 4.0 so no channel mixer.

Thanks Rob, very helpful, I will get that shot........

IIRC the special astrophotography version of the 20D was great for IR photographs, although that probably doesn't help you much.

All Digital cameras have a thin IR film on the CD surface, this can be removed to allow pure IR photographs to be taken but nothing else, so it would be an expensive mod to undertake......unless someone has an old digital SLR they want to give away:P I shall persevere non the less

Using the channel mixer like this all my pictures go yellow?

Any tips or further instructions on how to do this?

Sorry, you need to select the monochrome option. You should be able to tell from the intensity of the hues if the effect is working and if needed you can always greyscale is afterwards. A slight boost in contrast tends to help as well, but even with proper IR film I still had to use a grade 5 filter in the enlarger (very high contrast) to get a decent print!

HTH.

No, not true (presume you meant CCD?). See my post above or this link

Not convinced by their IR version. Their blue channel is too high. Clear sky should be black since in real IR, there is practically no IR light at all from the sky. The chlorophyll in grass / leaves is a very good reflector of IR light, hence why vegetation generally comes up very bright. I reckon it should look more like this:

Hi

For IR with digital, you are stuck with the IR blocking filter present on many but not all cameras. The channel mixer allows the sort of control of the various hues to get an IR like effect from a colour photo though. Also, somewhere around here I have a photoshop recipie for colour IR effect.

You could also try downloading Optiverve labs Virtual Photographer plugin for photoshop which gives you plenty of scope for experimentation.

This one was taken with a Minolta A1 then manipulated with the channel mixer in Photoshop:
