In Photography, the sensitiveness of the sensor to light is known as ISO. Understanding ISO settings in Digital photography is very important. In order to understand this better think of walking from a bright lighted room straight into a room with hardly any light at all, or a dark room. O...
Back in the film days, you would drop a roll of film into your camera and your ISO, or ASA as it was known back then, would be fixed for the entire roll. With digital, not only can you change your ISO on the fly, but you can also set your camera to adjust it automatically. I...
In very basic terms, ISO is simply a camera setting that will brighten or darken a photo. As you increase your ISO number, your photos will grow progressively brighter. For that reason, ISO can help you capture images in darker environments, or be more flexible about your aperture and shutt...
When you increase the ISO in your digital camera, you are simply increasing the gain. In the digital world, ISO is merely a way ofrenaminggain measurements from decibels (dB) to terminology more familiar to film users. In gain, each+6dBis the equivalent to adoublingof the electrical signal...
In photography, exposure is a critical element that determines what is actually recorded on a camera's image sensor. There are three adjustable elements that control the exposure - ISO, Aperture, and Shutter Speed. 1 The Exposure Triangle ...

如果我的相机设定为ISO100,实际上我就有100只工蜂。如果你的相机设定为ISO200,你就有200只工蜂。这些工蜂的任务就是采集进入到镜头的光线并形成图像。如果我们把光圈设为f/5.6,也就是说通过镜头的进光量一样多——ISO200的成像更快,因为工蜂数量是100的2倍。拍摄时间是一个阴天。光圈都是f/5.6,而你相机的...
An example of this is many of the Canon cameras, which have an ISO-50 speed below the ordinary ISO-100.In reality, consumer cameras cannot count individual photons. Dynamic range is therefore limited by the darkest tone where texture can no longer be discerned; we call this the black ...
blowing out the whites in your photograph. Understanding the relationship between all your settings on a DSLR camera — aperture, shutter speed, focal length, and ISO — is crucial to successful shallow depth of field. For example, the longer your focal length, the shallower your depth of ...
This means that sharpening can almost half the blur widths in an image, say, reduce them by 1/3 in practice. As long as the image noise is small at the given spatial frequency (low ISO in current dSLRs do the trick) and the resulting blur width stays above ≈ 1.25 ρ, this is ...
