I took this photo to make it look like Colin was balancing on Aleah's hand. I had to crop Vic out because it did not look like he was on her hand. I wish I would have had a plain background so there would not have been a lot of distractions like the man in the back. I used a shutter speed of 1/10 and it should have been a little faster to let in more light. I used an ISO of 100 and an aperture of f/18.

The topic 'Human Perception' is what I've chosen to study in Studio Arts this year. This is made from one photograph of me, just flipped around. It's to represent the two contrasting sides of how we can be percieved. There is this feminine beauty that so many of us live up to, the stereotypical features, which is what the left side would hopefully represent. The right side is a more down-to-earth, realistic view on somebody.
