APERTURE AND ISO

Aperture is the size the hole is on the camera lens that allows light to pass through to react. On the camera I used, F3.5 was the largest that let lots of light in and only the foreground, the tings close to the camera will be in focus, an on the opposite end, F22 was the smallest letting little light so that everything was in focus from the the foreground to the background. I tested this out.

The first time we tried aperture, it didn't work because I was in manual focus and it was out of focus slightly. If this photo was to be successful, as it was on F3.5, the clock and edge of the bench would have been in focus and the subjects on the and of the bench and beyond would have been out of focus.

In this photo, the aperture was at F9, so the clock and subject was in focus and the background (the trees, houses and grass) was out of focus.

In this photo, it was also on F9. The clock was in focus and so were half of the flowers on the trees, then halfway down the tree, they get blurry, along with the rest of the background.

This is a perfect aperture photo at F.3.5. The pen is in focus, as you can see the shine on the edge of it and the end where it has been bitten, and the edge of the paper and the subjects in the background are out of focus.

Here the aperture is at F22, but here, I placed the ISO at 1600, the highest setting, which created a very grainy image. You can see the difference specifically around the hair and a little on the face and leaves on the trees.
