Vince, I am using M8 to take these infrared pictures. From any RAW processing application - I am using Lightroom, they all look "magenta" - monochrome.
Below are my processing steps.
1. RAW processing output to TIFF file - without any adjustment.
2. Photoshop
2.1 open the TIFF file, then click on "image" -> "adjustment" -> "channel mixer".
2.2 "Red" channel - set "Red" value to "0", "Blue" value to "100".
2.3 "Blue" channel - set "Red" value to "100", "Blue" value to "0".
- the image should now showing "Blue" sky & "pale Yellow/Magenta" plantation.
- the colors of "Blue" & "pale Yellow/Magenta" & saturation depend on the IR cut off wave length of the filter - I am using Leica's filters & do not know the IR wave length value.
2.4 save the TIFF file and this is the "IR RAW" file I am using in LR processing.
3. Lightroom (LR)
3.1 open the "IR RAW" file.
3.2 adjust as other normal "RAW" files for "color temperature", "exposure", "contrast", etc .....
3.3 this is my personal steps for IR taste - one has to play with these steps
3.3.1 adjust color tones (hue)
3.3.2 adjust color saturation
3.3.3 adjust color brightness
3.3.4 repeat 3.3.1 - 3.3.3 as needed
3.4 output the "IR RAW" to "JPEG" or "TIFF" as one's choice & this is the final image.
I had took some IR slide films in the 80s & eraly 90s. The colors are very vibrant & saturated.
All my digital IR images are tried to imitate the slide film as close as possible.
Here is a link of color IR slide images - [url=https://www.google.com/search?q=color+infrared+film+images&client=firefox-a&hs=66M&rls=org.mozilla:en-US fficial&channel=sb&tbm=isch&tbo=u&source=univ&sa=X&ei=VcBGVJmzK5SryAS124CoDw&ved=0CCIQsAQ]"Infared Film Images"[/url]
