bobfriedman Posted June 9, 2018 Share Posted June 9, 2018 Thought i would try out the D800 UV-VIS-IR with the 17-35/2.8D and RG1000 combo Not the best cloud day...

Cadmium Posted June 10, 2018 Share Posted June 10, 2018 Bob, Great shots! I am trying to see the difference between the top shot and the bottom shot, seems like there is some, what is your assessment? Link to comment
colinbm Posted June 10, 2018 Share Posted June 10, 2018 Steve the foreground leaves in the top left corner in the last image are not the same in the first image.....;-)Col Link to comment
Cadmium Posted June 10, 2018 Share Posted June 10, 2018 Yeah, Thanks Colin, I got that, but that's not what I meant. Link to comment
bobfriedman Posted June 10, 2018 Author Share Posted June 10, 2018 both are pretty close.. up to some post processing differences.. i guess the 17-35/2.8D works pretty well Link to comment
Andrea B. Posted June 10, 2018 Share Posted June 10, 2018 My curiosity is this: Typically the RG1000 gives us those very dark, almost black skies. So I'm assuming that your conversion has lightened them somewhat? The angle of the tree trunk/branches in #1 and #3 is very cool. Link to comment
Andy Perrin Posted June 10, 2018 Share Posted June 10, 2018 Andrea, that far in the infrared the Bayer is transparent anyway, so I don’t see how Bob’s conversion can affect the sky lightness. I think it is just clouds. Link to comment
Andrea B. Posted June 10, 2018 Share Posted June 10, 2018 Yes, I think you're right. I didn't realize at first that the first & third frames also had the clouds as in the 2nd frame. I always love how IR leaves & branches look against IR sky. It makes a kind of lacy pattern. Or maybe an almost fractal pattern. Link to comment
Cadmium Posted June 10, 2018 Share Posted June 10, 2018 Bob is using RG1000 1mm thick.I had the RG1000 and RG830 pics reversed in my mind, they make more sense to me now that I know the top one is RG1000 1mm and the last one is RG830.Water, sky seem to be slightly darker with the RG1000 1mm than the RG830, but I don't know the thickness of the RG830.Definitely you are correct, RG1000 2mm will make for darker black skies and water than RG8730/RG850 do. RG850 2mm is my personal choice. Keep in mind, the Schott data for all these ends at 1E-05 for 3mm thick, so thinner versions still suppress beyond the flat lines shown, but there is no deeper data provided to show that or calculate from.
