Hi I'm Dan Reinecke with Unknown Media. Today lets talk about ISO vs. F-stop vs. shutter speed. Now what this is going to dealing with is the exposure of your image. So say your image is right here, medium exposure. You got your aperture or your F-stop. You got your ISO and then you got your shutter speed. Alright so if you lower your F-stop or drop it down basically what that's going to do is it's going to eliminate light from your photos. So now it's a little underexposed. Now opposite of that say we open up the aperture boom we're adding light to the image. So now it's a little overexposed. Now it's all about a balancing act between the aperture, the shutter speed, and the ISO. Say we go ahead and we lower the F-stop so we are losing light here but we actually lower the shutter speed which allows more light to come into the camera so it's going here. And now that that is going to do it actually balances it out. So again this whole thing is going to be more of a balancing act rather then them working against each other. Say you want something with a real shallow depth of field. Go ahead and open up your aperture as wide as it will go so you can get that real shallow depth of field but now ultimately this is going to make your image a lot brighter. So what you can do is lower your ISO if possible. That will actually bring the exposure down. Or you can raise your shutter speed which again will bring down that overall exposure. But again it's just finding that middle ground. It's finding that nice even exposure where everything is balanced correctly to how you want your image to come out. So that's a little insight on ISO vs. F-stop vs. shutter speed. I'm Dan Reinecke, take your best shot.
