Tuesday’s Tips & Tricks | Shutter & Aperture together

The last two tips and tricks, we talked a little about shutter speed and aperture.  So this week we will go over how they are used together.  How fun will that be?! 🙂

So… you have your camera.  (Film or SLR)  Here’s basically what is happening inside with the shutter and the aperture:  the aperture is the diameter of the lens through which light exposes the film.

By making the size of the aperture bigger or smaller, you control the volume of light entering the camera.

The shutter is the mechanism that opens and closes to control the length of time the light is exposing the film.

The aperture and the shutter are connected meaning that one cannot be altered without the other being altered also.

Your camera usually has TTL metering (through-the-lens light metering).  If not, you can use a separate hand-held light meter.  The meter takes a reading of the amount of light reflected off your subject.  However, to get the correct exposure combination, you also have to tell the meter what speed (ISO rating) you have your camera set to.

So according to the above chart (which may vary slightly with your camera), to get a correct exposure, the bigger the aperture (f/2 or f/2.8) the faster the shutter speed (1/1000 or 1/500 of a second).  This gives you a smaller depth of field and less movement blur.

On the opposite end, the smaller the aperture (f/16 or f/11) the slower the shutter speed is used (1/15 or 1/30 of a second).  This gives you a greater depth of field and more movement blur.

So what combination should you use?  Depends on what you want your picture to look like. 🙂  Do you want to show movement or stop movement?  Do you want to have your depth of field large or small.  First decide on that.  Then set your aperture and shutter speeds accordingly.

** one thing to remember is camera shake.  You want to have a shutter speed fast enough to prevent camera shake if you don’t have it on a tripod. The longer your lens is on your camera, the more camera shake you will get.  Here’s a little guide to help cut down on camera shake blur:

Traditional Safe Shutter Speed Chart – 35mm SLR
Lens
shakey hands
steady hands
35mm (wide)
1/60
1/30
50mm (standard)
1/125
1/60
100mm (medium zoom)
1/250
1/125
200mm (high zoom)
1/500
1/250
300mm (high zoom)
1/1000
1/500

So if you have a 50mm lens (for example)  that you are shooting with, try not to go to a slower shutter speed than 1/125 if you have shakey hands or 1/60 if you have steady hands.  Once you hit that 1/30… you will start to get camera shake.

Ok, that’s all I have for today.  Hope this is useful information for you.  Come back next week for more tips and tricks!
