The ISO Setting

A few weeks ago I posted some information on what may be the most important settings on a DSLR.  The ISO, stutter speed and aperture.  Today I will talk a little about the ISO.  The ISO setting is a part of or setting that controls the exposure of the image.  ISO is a measure of the sensor sensitivity to light. The best setting of the ISO is going to be low (50,100,200) which is going to produce low noise and a sharper image, but a low ISO need more surrounding light. This setting is great for outdoors.  A high ISO (800, 1600, 3200) needs less light and will have more noise and less shape. This high setting is good for indoors (dark) or where flash is not permitted.  So, to sum it up a high ISO is best used in low light situations. A low ISO is best used situations where light is not that big of an issue.  That’s it, not too much to it. One more thing to remember, changing the ISO does change the noise (grain) and the sharpness of the photo.  Play around with it in different lighting and see what works best for you.  Next time I will talk a little about the aperture and f-stop.  Till then have a great one.
