Newer cameras sensors are less sensitive to IR light & as such, require greater exposure times. I used to use a Hoya R 72 IR pass filter (729nm) on my Nikon D70s for IR shots. After shooting, I still had to swap the red & blue channels in PS in order to get the IR effects. Thing was though, my camera could still auto focus with the filter on & the shutter speeds were not that long. The D70s had a CCD sensor, not a CMOS sensor though. Haven't tried using the filter on either any of my current cameras though. Oh, yes, you still needed a custom WB taken from grass for best results.

I have decided to say goodbye to Lightroom and have a number of publications available for what I hope will be viewed as a win-win.
The condition of these books is used but good. Some have marks in them, many do not and I’m not going to identify them.
The books will have the title, author and the original price of the book. Now pay close attention! You pay what you think would be fair.
I will mail the books at the post office at a book rate so add a couple of dollars to help defray the cost (or not.)
I want to empty my shelf and no offer will be rejected. It’s strictly first-email-first-serve. I will decide who gets what by the date and time on the email.
I hope this works for everyone interested.
