There is no exposure information accompaning your photos so no one knows what to suggest. Most of the others here are also beginners.
#1 is underexposed and the conversion to B&W lacks contrast.
Didn't convert to B&W, was shot in monochrome.
Google "photographic exposure" and "B&W conversion"
#2 has an strange green color cast usually indicating a possible improper white balance setting. Read your camera manual.
tried to fix the pink hue in post, looked fine on my computer but it was super late at night and all lights out, so today it does have a green color to it... thanks
#3 again underexposed.
underexposed... any ideas?
What shooting (Auto, Sv, Av, P, M?) and metering modes are you using (spot, center-weighted, evauluative)?
was shot in Av, evaluative metering on all of them.
