and really like this picture
it doesnt matter if its on auto focus leave it on it, it makes life easier
what you need to learn is apature priority,A
and manual.
i suggest looking online about exposure and fstop to figure it out, but if you need help understanding your camera i have the same one so you can im me if you like.
I edited this photo a little bit to make the colors pop a little, and aperture is the amount of light that is let in right? The thing is, is that I dont always have time to adjust my aperture..Most of my shots are of people or animals moving..or people that dont have any patients.
