Iso on camera meaning iso#
The two below pictures was made at high ISO settings of 32 on a Canon 30D camera. The smaller the number, usually ISO 80,100,200, the better picture quality picture we can get, usually the smallest number ISO gives the best picture quality. For this we must increase ISO usually, if we don’t have sharp bright lenses, or have not so bright lighting situations. A tripod is not helps in freezing action. Sportsįor sports photography usually higher shutter speeds(1/500s or higher) preferred to freeze action. If we photograph a still subject for example bird on a tree, we can use tripod and can work with lower shutter speeds, which translates to lower iso settings. Needs to use at f/8 to makes sharp shots, meaning you need more light or higher iso for the same shutter speed in order to make a sharp shot and freeze action. Typical consumer grade telephoto lenses are not sharp at f/5.6 aperture.
No chance must increase ISO or get brighter sharper lenses. Wildlifeįor wildlife like sports high shutter speeds need, to freeze action.
Inside in badly lit conditions do not hesitate to increase the ISO or use a flash. Portraitįor portraits we usually use bright prime lenses, which helps to use lower settings. The low settings here gives an exposure times of several seconds or ten seconds, see the picture above. At dark situations the pictures at higher settings are much uglier. For this picture I placed the camera on the existing concrete structure.Īt night I prefer to use low iso settings with a tripod. The low ISO settings and long shutter speeds (several seconds) allows the vehicles to draw interesting lines on the picture. If the subject stands still, not needed very high shutter speed, but sometimes it is in the shade which requires higher ISO settings. The iso 3200 setting is too much, image quality is degraded Macroįor macro many people use tripod so the shutter speed determined by the subjects speed. If you don’t have a tripod, you can increase the ISO up to 400 or 800 in extreme cases usually without much image quality problem. If there is not enough light, a tripod or some support is a must. Why? For two reasons, the first is here the dynamic range is the widest (the camera ability to capture bright and dark details on the same picture, which is most important at landscapes), and here is the best the overall picture quality.
Here in this genre of photography is the most important to keep the ISO low, preferably ISO100 or lower. Iso 100 1/15s f/8 here I use the stabilizer, longer shutter speed is used to show the water blurred ISO – What does iso mean ?
