What is ISO speed? Is it good to have higher ISO Speed?
ISO is a definition of how quickly your camera absorbs light. The higher the number, the faster it absorbs light. Now, one would think: “higher ISO equals brighter, faster, better shots” right? Not entirely the case. The higher your ISO, the more “noise” you encounter. Noise is little marks of discolouration in solid areas of colour. So for example, it a large area of black or grey, you’ll see flecks of red, blue, green, yellow, etcetera as you look at it. The higher your ISO, the more pronounced these flecks will be. Most current digital cameras try to combat this, however point & shoot digital cameras cannot combat it overly well. Better than they used to, but still not all that well. The difference between “Superfine” and “Fine” is as follows. When your camera takes a picture, it converts it into a JPeg image. In doing so, it has to compress and chop off a bit of information. These “fine-ness” settings tell the camera to keep from removing a certain amount of information. Superfine
