Shutter Speed

Shutter speed affects lighting and movement, so in this pictures i had my partner stand under a lot of light ,in the other picture i had my partner walk so i can catch some movement. The shutter speed i believe is important when lets say you want to take a picture of some one moving and some one standing still the shutter speed believe it or not has a lot to do with having a good picture

Iso

The difference in these three pictures are the iso i learned that the higher the iso the brighter the picture comes out. Also using flash in a picture can sometimes ruin a picture, it may take away some artistic lightning from the picture. These are important when wanting to get a good picture that's non blurry and with good lightning.
