My great grandma is having a 90th Surprise Bday party. I am by no means a photographer, but my grandmother has told my aunt that i have a good camera & I would be more than willing to take pictures. I don't do much but dablle with the the camera & do take some portraits of our kids, but not really anything spectacular. It will most likely be low lighting and I want to get some good pictures. I have the lens that comes with it, but would be willing to purchase a better lense if need be. ANy and all tips you could give me would be wonderful, I have about 2 weeks to practice before the big party. Thanks.
