I have been wanting to do a monochromatic cloud series. Ming Thein beat me to it but he inspired me to get off my lazy ass and edit the images. One of the things with editing photos shot through the thick glass of a jet moving at rapid speed is that grain shows in the images no matter what unless you take a ton of time to edit it out or size the images down so its not noticeable. I leave my images at 1500 wide to force myself to be a better photographer and skip the fix it in post mentality with removing noise. You also lose fine detail when you start to remove noise too aggressively. In this case with using SilverFX from Nik Tools to do the monochormatic conversion it adds “grain” to the image and while you can turn it off it disables other functions I use to quickly filter color. The upside is that it does add to the image and gives it the shot on film look.
I’ll skip my rant on people touching the damn windows in airplanes and how much I hate removing their greasy finger prints!
