yes, i was shooting in auto mode ... ive tried shooting in manuel but i feel like i have a lot more to learn first
I can understand where you're coming from. What I would do if I were you though - stick to
M, A, S, P on your Nikon's scroll wheel.
P (program) is very automatic - you set your ISO (which should be at 100/200 for daytime shots like these) and the camera decides the rest.
A (aperture priority) is for setting the size of the hole in your lens and the ISO, and letting the camera decide the rest. It might have been nice if you used this for some of your portraits, setting the aperture to the largest size (smallest number) and getting in close will help to separate the person from the background (blurring the background). It also helps to have the 'background' far away..
S (shutter priority) is for setting the shutter and ISO - letting cam do rest - and is good for when you are trying to freeze motion and need a fast shutter speed, or with a telephoto lens.
M (manual) simply lets you set everything yourself.. it's important to learn sooner or later but it's not always practical for everyone and could cause you to miss shots as well - especially if you're not familiar with it.
Another benefit to sticking with these, your flash won't popup on its own - which can be annoying.
Ok, sorry that was long - and all that info is in your instruction manual that comes with the camera, not saying you haven't read it.
Also, while I was typing this super long post, someone has probably advised you to read the book "Understanding Exposure" by Bryan Petersen. I've honestly never seen a more recommended book.
EDIT: nope, looks like I beat them to it.
Good luck, keep posting
