To understand how they work with one another, we quickly need to take a look at the scales for each.
#F stop shutter speed iso#
ISO rating, F stops, and shutter speeds all work in relation to one another to make a correct exposure. With digital cameras, you can change this at anytime, with film you needed to change the roll. A high ISO would be the clear glasses, a low one would be the dark glasses. The clear glasses let in the most light, the lightly tinted let in a bit, and the dark hardly any. Back to the window one last time, this time inside we have someone wearing a pair of clear, lightly tinted, and dark sunglasses. Something with an ISO of 50 is MUCH less sensitive than an ISO of 800. This one is pretty simple, the lower the ISO rating, the less sensitive it is to light. ISO is the rated speed (sensitivity to light) of the film/image sensor. open it just a foot or so, and only a small beam of light comes in, throw it all of the way open, and much more light is allowed to enter the room.

If we move back to the window analogy, this is how wide we open the curtain.

The higher the number Fstop, the smaller the opening (ie an f stop of f/22 is a much smaller opening than one of f/2.8). The aperture, or F stop as its shown on the camera/lens, is the size of the opening within the lens.
#F stop shutter speed full#
Shutter speeds are expressed in fractions of a second ( 1/250, 1/500, etc or in full seconds or minutes for longer exposures, 3sec, 20 sec, 5 min, etc). Leave it open longer, and more light comes through, jerk the curtain open quickly and back shut, and less light comes in. If you have a window with a curtain over it, shutter speed is the time it takes you to open and close that curtain. The shutter speed is how long the shutter of the camera is open, and exposing either the film or sensor to light. When taking photographs, you have three basic exposure controls that allow you to adjust for lighting differences and also allow you creative choices.Īnd ISO (film speed for those that remember film). If you have ideas feel free to email me at and ref the blog (and for those following along the BT you can either email me, post on there, or PM me). With that said, this will be the first of many posts and i'm more than happy to post topics/discussions of almost anything.
#F stop shutter speed how to#
This is meant more to get the basics down for those interested in learning how to use their cameras, not an in depth photography class. If you want to get into the science behind how some of this works, either search online, or get a hold of me personally, i do run one on one or group online photo classes. I'm going to keep things on here simple, in basic terms. I'll be posting photos soon that help explain as i go along, but to start with just some basic info. Before i get going into the meat of this, i wanted to share a few quick things.
