I worked with Glenn this afternoon and we installed the new ceiling fan in Benjamin’s room.
Once we got the fan running I tested out some of my camera’s ISO settings.
Back in the day of photographic film the size of the tiny crystals in the film affected how quickly it would react to the light. The larger crystals would capture the light faster and expose the film less than smaller crystals.
In digital cameras ISO refers to the speed at which the digital sensor reacts to the light. ISO also affects the clarity of the image. Faster ISO speeds produce noise, but the slower ISO produces a smooth image that is very susceptible to camera shake.
Most of the photos that I post on this blog have been taken on the fly and usually with one hand! When I know I may need to take a photo quickly and probably without stabilizing the camera I set my camera to a fast ISO setting.
The images below demonstrate a few different ISO speeds:
ISO: 1600 The larger the number the larger the crystals were.
ISO: 800 High ISOs speeds are hard to blur with camera shake, but they can also create noise/grain.
ISO: 400 Take a look at the 3 photos above and look at the darker parts of the photo you see the little dots? That is noise.
ISO: 200 With the slower ISO the picture looks smoother, but more blurred.
ISO: 100
ISO: 80 The ISO speed is so slow that you can’t even distinguish the ceiling fan blades.
If you take a look at the photos above they all look very different even though the speed of the fan’s blade’s never changed. Whenever you are taking pictures of moving water like a waterfall adjusting the ISO is one of the ways to get different photo effects.
