The Speed of Shutter

In week two of the 2 Peas 12 Weeks to Better Photos coarse the lesson revolves around ISO and Shutter Speed.

ISO refers to the film speed, how fast the sensor will capture your image. The ISO you choose with depend a lot on what the light is like where you are shooting. Bright sunny day out? ISO 100 will do. Overcast? 200-400 might be better. Indoors you'll most likely need betweeon 800-1600 depending on hor much light you have availible.

Shutter Speed is how long the camera shutter remains open to expose your sensor. It is measured in fractions of seconds (I know I hate fractions too). The slowest you can usually go without a tri-pod is 1/60 of a second and you can go all the way up to 1/1000 of a second. The length of time your shutter is open determines how much of the action in your shot is blurred or frozem. To go more in-depth with wither ISO or Shutter Speed and how they work check out the link to the 2 peas lesson.

Ok so for this lesson they do what is called the kitchen sink test. You are supposed to take pics of the water running from your faucet in your kitchen sink at different shutter speeds. However, my kitchen is directly under three HUGE pine trees in my back yard, so it never gets enough light. Instead I did mine in the laundry room where there is more nautral light, but still not a ton (which ends up being a problem). So let's call this the washing machine test.



For this picture I had my Shutter Speed set to 1/80th of a second. As you can see the water is completely blurred. Slower Shutter Speed = blurred action. Photobucket


For the second one I had the Shutter Speed set at 1/800th of a second. The fall of the water has been frozen, you can see the ripples and a few droplets. Higher Shutter Speed = action is frozen. PhotobucketYou'll also notice the exposure in this one is also a lot darker than in the first. I couldn't take the shutter speed up any further than 1/800 or I would have had a VERY underexposed pic. Also, because of my lighting issues I had to set my ISO very to 1600, this makes the picture very grainy. That is the price you pay for higher ISOs.




Annnnnd my favorite pics of the week:
