Hi everyone!
Thank you for welcoming me in my previous post.
I'm not sure if nightscape (?) fits into landscape category in this site, but since I have two trees
I learned what LGP (Light gathering power) a few weeks ago. Please pardon my ignorance, but I thought 14mm f/2.8 gathers the same amount of light as 35mm f/2.8 because they have the same f/2.8. I was told that I should compare (not calculate) two lens with the following equation.
pi*(14/2.8)^2 = 78.54
pi*(35/2.8)^2 = 490.88
400 / 14 = 28.57
400 / 35 = 11.4
78.54 * 28.57 = 2244
490.88 * 11.4 = 5596
basically, 35mm f/2.8 gathers 2x more lights. With that in mind, I rented 35mm f/1.4 and 50mm f/1.4 to see how much detail I can get with relatively short exposures from those two lenses.
These are my output. Although I did heavy processing on both of them and there is noise when zoomed, but I think both came out pretty okay.
Two trees: 35mm f/1.4, ISO 6400, 8 seconds.
lone tree: 50mm f/1.4, ISO 6400, 6 seconds
Thank you for looking!
