I went into a dark room and turned the lights off and drew a heart with my phone flashlight while the picture was taking.

I took string and spelt out my quote and put marble boarder around it.

ISO Station 

When I changed the ISO for the first set they got lighter/Brighter. When I changed for the second set they got darker. 

Aperture Station 

As I changed the F-Stop each time the pictures got burlier. I didn't notice a change in the camera though. 

You wouldn't be able to catch it as fast if you changed the shutter speed because it is slower.
