Shutter Speed

In our first photo,we out lined our partner Latoya body with our cell phones.In out perfect picture we just got together,it was a group picture.Everyone got in a place where they felt comfortable.In the last photo that looks like a wind of light,we had our phones out waving them around then we timed the picture,we all jumped out.The picture didnt have anyone in it,it just had the light.The setting for all our pictures was in the front of the classroom in the corner by the door.We had to set the ISO to 400 but the aprture was set to the lowest it could go.We set the shutter speed to about 8 seconds.Doing this project was fun because the pictures always come out cool with the lights.Only thing that was difficult was we couldnt really tell when the photo was took so he had to keep doing the same thing over and over to get the picture the way we want it.ISO and Aperture interact with one another to let light in and give us how much light we want.
