In these we were in somewhat complete darkness, I could see my feet so it was dark. We were fiddling with shutter speed, aperture, ISO, and glow sticks. We had the cameras set to M (manual) in this mode we control everything WB, ISO, Aperture, and Shutter Speed. Shutter, but the one that did the most work was shutter speed. What it is basically, is how long the shutter is open. Either it is open for half a second or even fifteen seconds. But depending on where you are you should always check what it is on if you are in M mode. This is where ISO and Aperture come in. ISO tell the light to come in, and Aperture is how bit the hole is for the light to come into. So in this case the hole was big and iso was set somewhat high we could only go to 400 so no that high. But put with Shutter speed, ISO, and Aperture the picture came out awesome.
