Exercise 2c: ISO
2c.1) ISO effects exposure
2c.2) ISO effects image quality
Exercise 2b: Shutter Speed
Lecture
I learn ISO can also affect the light of
the picture, and if I use lower ISO then my photo will become clearer and
if ISO is high then there will be more noise in the picture. Today class we
also learn about shutter speed, when we use fast shutter speed we can take
picture like freeze, but 1/50s speed is only normal speed. If we want take the
sharp of moving subject, we can set shutter speed slowly like 3-5s then we can
get a flow picture.
Instructions
Exercise 2c: ISO
2c.1) ISO effects exposure
2c.2) ISO effects image quality...
Upon reading, viewing and discussing the material on ISO, we have come to agree that ISO effects exposure (Exercise 2c.1) and effects the quality of an image (Exercise 2c.2).
Your in-class task today, requires you to prove that:
2c.1) ISO effects exposure
2c.2) ISO effects the quality of an image by increasing the noise and grain of a picture.
Exercise 2b: Shutter Speed
We have already proven that shutter speed effects exposure (2a & 2c). Your task is to now prove that shutter speed has the ability to freeze fast moving objects and blur moving objects.
All images must be in black and white, using sun light. Ensure you are shooting at the highest quality JPEG.

Feedback
Reflection
Experience - Last week I didn't use the sun light, so I did wrong work at the beginning.
But after I know this I take photo again and do It right. So i need to pay more
attention on the class, obey all rules of class then I can take the nice photo.
Observation - Even a little set change can change a picture, so when I shoot photo I
need pay more attention on it, and try to find all right set and take.
Findings - I learn how to change shutter speed , aperture
and ISO, those three main set control the picture quality, even I cannot find a
big different from picture , then the quality will change by use different
aperture shutter speed and ISO
