ITs hard to tell from those pics though I would lean female at this point. Looks like you are using a web cam. They dont need to be so close. Try getting a couple pics, same angles, that are about where your face is in the second photo. They should be more clear
The pictures aren't very clear, but the coloration of the chameleon makes me want to say it's a female. If you can get some clearer pictures of the tail base area we will be able to help you out sexing him/her more accurately.
Positive that is a female. You got to make out the blur. It's not too hard if you look at it for 20 seconds or more lol. Try putting her back, a lot more from the lens next time bro.
