I'll definitely run to Walmart and look into that... and add an actual one to my list of things to buy.
As for the test photos watch your backgrounds the post in the first shot the other girl with the cut off head in the third and the stores and parking lot in the last detract from the shots. Watch your focus if you know how to focus using the focus point of your camera and recompose focus on the eyes and then recompose. Usually this is acomplished by pressing the shutter release about halfway down. I like the composition on most of them other than the things I already mentioned about the background.
I'll have better luck with the backgroud with the real models tomorrow. It will be at the park and there's tons of beautiful scenery! The area where I was shooting these ladies didn't give me much to work with... The one with the head cut off... I knew that would be awkward when I saw it on my computer but thought it was a great shot of the girl it was focused on.
I do know how to focus by pressing the button half way down but need to read the manuel to find out how to do multiple focus points. There's a red dot inside and I usually point that at the area I'm focusing on... lol I know what I'm saying sounds so dumb and inexperienced to you guys who are professional... lol But I'm learning. Keep the critiques coming...

Also what about those of you who have done headshots. What do you think about the lettering I did? Any suggestions?
