Yes I must admit, the processing is the hardest part to master. Wish I could find a good guide somewhere.
I had a bit of a search as just bought the R72 filter to have a go at IR.
Hopefully these articles may be of some help:
Taking IR photos
Processing IR photos
After reading a thread on another forum, I ordered a Hoya R72 filter 52mm for the EOS-M just to give it a go.
The camera won't focus as it's too dark, so basically manually focussed, carefully attached the filter then rested the camera on a wall and guessed at where to point it.
ISO was set at 800 and aperture f8 and f11. Exposure times between around 8 and 25 seconds.
Lens was the kit 18-55, mainly at 18mm. Shooting in Raw.
Although a bit blurry and and far from great shots, the following were the results from my first go at IR the other day.
Looking forward to doing a lot more with a proper tripod.
As I understand it, if you do get a body converted, then the IR light isn't blocked by the camera's filter so should allow faster exposures and enable AF on the camera.
Processing was via Photoshop (varied colour temp to around 2000 and tint to around -50 in camera Raw), then messed with channel mixer and also used Nik Silver Efex Pro plugin after reading the tutorial linked above where the writer uses it. Was pleasantly surprised to find the Google Nik suite is available to download free of charge. Used Silver Efex Pro 2.0 to convert to B&W and also increase contrast and "structure".
