exposure is a very important element when we do film and photograph. I think I still have a lot of thing need to learn about exposure. I used to feel really confuse about the relation between aperture, shuttle speed and exposure. So I bought a SLR this year to figure out( Yes, not DSLR, it is a old SLR!The simple is the best) Even though I still not good at adjusting exposure, BUT  MUCH  BETTER…understanding.

The use of aperture will not just affect the exposure but also affect the depth of field of the frame. The large aperture will create a shallow depth of field, the small aperture will create a deep depth of field.
