How does F.lux shift color? Trying to emulate in photoshop.
When F.lux kicks on at night I've noticed that some greens become more vibrant, while other greens become muted. Some blues turn black, while others shift to green. Google image search plants while in bedtime mode and you will see what I am talking about. The lower the K setting the more pronounced the effect.
I'd like to recreate this look in photoshop, but I cant get the hue shift right. Can someone explain how f.lux works?
I'm also trying to emulate this effect for a book cover.
If you managed to find out do you mind posting below. Cheers
The closest I've been able to come to replicating the effect:
Create a curves adjustment layer.
Select the blue channel and lower it over halfway.
Select the green channel and lower it, but give it an upwards bend in the shadows.
Don't touch the red channel.
If you drop the blue channel all the way down, blues will turn black, just like a real red camera filter.
It's taken me a lot of tinkering with every possible filter. But I think the answer is in curves.
thanks, pretty helpful.
for whatever reason it seems difficult. maybe impossible to get exactly.
