100) will not be very sensitive to light whereas a high setting (e. And, in fact, you don’t need to know what it is ? just how to use it.g. First, you will get a ?noisier? image at a higher ISO setting (more grainy ? but this can often create a nice effect) and secondly you must remember to switch back to your usual ISO after the shots have been taken (so High Mast Lamp that your usual images have the optimum ISO setting).
But if the light is fading and you don’t want to use flash, then the shutter speed for the same aperture might reduce to 1/30 or 1/15. 1600) will be very sensitive.

That’s it really.
Do you know what ISO is? Perhaps not. Normally, on a normal bright day, you would use programme mode or a semi-automatic mode which will select an aperture of 5.
How does this affect you?
It’s simple, and don’t let others tell you otherwise.g. A low ISO (e. If you have plenty of light around ? say on a sunny day or if it is bright but overcast, use ISO setting 100 or 200.6 and shutter speed of 1/250. In fact, keep it at that setting for most of your shots.
There are two drawbacks.
If however, you are in low light levels, you may wish to use flash (keep the same ISO setting) OR use a higher ISO without flash. Then just take your pictures as normal. No problem. Therefore you will be able to use a faster shutter speed in low light conditions with a higher ISO.
. At slow speeds like this you will find your shots are not as sharp due to camera shake. In very simple terms, the ISO setting is a measure of how sensitive Spotlight Housing your camera sensor is to light.Read more:http://www.gentwin.com/product/led-lights/led-high-mast-lighting
