These haven't had any--I did just a bit of contrast on the ones yesterday, none on this one--just cropped a tiny bit. Now, my original ones would need post work. I should post one so you can see what I got in the beginning. Okay, this is what I got for my very first shots. I was following instructions of one of the digital IR sites--use sun/daylight setting for whitepoint, use Tv mode (shutter) at a time that would give you f6.3. Use the daylight/sun because it would lean toward green channel--then split the channels and work with the green channel which would most likely be sharper, etc. Well, I really wanted some sepia and preferably some cyan too, so I switched to manual and custom white point. This is the photo--done as I said above. Below this I will post the green channel with a bit of contrast added. Nothing wrong with it if I want all b/w--which I may for some, but in some cases, esp. when I use very white as white point, the photos lean toward mostly b/w.
