F-stop is how much light is coming into camera
Shutter is how long the light is coming in
ISO is how sensitive the sensor is to light.

F-stop to 22, iso to 100 and shutter at 4000th of a second will let little to no light in.
F-stop at 1.8 iso at 1600 and shutter at 1/30th will let in alot of light.

F/1.8 is larger than F/22
iso 100 is less sensitive than iso 1600
shutter 30 is longer than shutter 4000

play with that concept and good luck =)

Is increasing the ISO really needed when you have a tripod and plenty of time to play with the F stop and shutter speed? I’m still new to photography so I’m not sure but I always try to keep the ISO as low as possible.

I’ve read that increasing the ISO on a digital is just increasing the power output of the CCD which can cause noise in the picture.
