I’m now using RT 4.2.927 and just wanted to say that the new limit for the tint slider works great for my infrared photos taken with 830, 760 and 720 nm IR filter, from a variety of converted cameras that I have owned over the years. Below is an example of a photo taken with a Panasonic GX1 and 760nm filter, eyedropper on the foreground vegetation. This image would have turned up with a magenta cast with the previous limit. Great job, RT now does everything I need!
