So I recently made a logo for a friend who does free " photography sessions " for people... but I've been looking at her pics and there pretty grainy... she even uses a high end canon ( im not camera savvy ). I think its a canon rebel II or something like that

shes obviously an amateur but I'd just like to help her out so her stuff isnt so grainy

Why are her photos showing up like this? :

First, a Canon Rebel (anything) is not high end. It's the bottom of the low end. And quite possible she has on a higher ISO like 3200 or something. And she should probably learn a little more before giving away free photography sessions. And after she knows a little more, she shouldn't give them away for free but for money. Just my 2 pennies.

Well, since you asked how she could improve the grainy-ness and nothing else, I'd say she has too high ISO on her camera. Lower that!

I use an even lower end camera, and the iso setting is very poor on the rebel series cameras. I know they've improved it since my model (rebel xti) , but there are much better ones out there.
