* F Stop - The lower the number the more light gets into the camera. Also, the shallower debth of field so… if you want lots of light or a blurry background, use the smallest number possible.
Things to remember, close up larger groups need to be shot at a higher number or the people on the edges will not be in focus. If you need the light, the other option it so stand further away from the group at the lower setting.
Think of your lens like a target. If you use a single point focus that point is your center of the target. A small number is a small target. The bigger your number the bigger the target.
* Shutter, anything below the number 60 on the dial becomes difficult to hold still. Your heartbeat will be enough to take away the sharpness of the image. Kids playing and you don’t want it blurry… make your shutter speed a priority, 150 or higher!
This is your quickest and easiest setting to adjust when you are close to the correct exposure or the light is changing like a setting sun or a cloud floating in front of the sun.
* ISO – adjusts how sensitive your sensor is to light. Think to remember, images will start to appear grainy as the number gets higher.
Bright space = lower number / Dark space = higher number
When you are setting up a shot try choosing your settings in this order.
ISO = Think about your hard rules when you are about to take a pic and walk yourself through your settings. If you are like me and don’t like noise/graininess then leave your ISO at 400 or less. Unless you are outside in broad daylight, 400 is a good place to start anyway. (sometimes at events a constant popping flash can be distracting. Sometimes it’s just necessary to bump up the ISO. If you choose this route you can use the noise reduction feature in lightroom.)
FStop = Do you want to background blurry? Are you shooting 3 or more people? Are people moving or holding still for a portrait. How big do you need your target to be? 5.6 is a great place to start.
Shutter Speed = If you use this technique then your should just match your shutter speed to the above 2 settings. Choose whatever will give you the correct exposure.
Trouble shooting work backwards up this list…
EXAMPLE: With the correct exposure my shutter is under 60… I want it higher to freeze motion and need it at least at 150. Adjust to 150 but now my images is too dark… lower the fstop. Your lens won’t go any lower and the image is still too dark. Make the ISO higher.
