Some images can send positive or negative messages and knowing which is which is really important. Most of the time you wan't to lead towards positive then negative messages. How do you do that, just make sure there is nothing inappropriate or bad happening in the shot. I think sad messages are the most confusing to understand like a dog's sad eyes it could go either way! But inappropriate or bad things happening in the shot I would have to say that is a big ol' negative shot.
The message I intend to put out there is hey I'm a cook I love to cook on the stove or the oven! This has stuck with me ever since I was a little kid and I just love making instead of buying. So I wan't people to think man I wan't this dude to come to my house and cook me gourmet-ish foods (I wish I could but please don't ask). I love to cook for my family like fried noodles and brownies, my family mops (means eats and eats in my house) this awesome creations. So cooking and dealing with food the smell in the air is what I enjoy and I am trying to send as a image.
