Study Aperture and DOF today!

This is a photo I practice different aperture today in TAFE class. Today is a busy and full of knowledge day. In the photo class today, we learned some important concepts as follows: aperture(large or wide and small), depth of field(shallow and great)also other useful expressions (such as subject, weak and strong composition or design). At the same time, I find it is a perfect way to review what I have learn every day when I insist to post photo to Blipfoto day by day. Thanks to Maria! :)
