it is the building block of a picture. If you are a beginner in photography, you may find it tough to control the ISO settings in your camera in different conditions, especially when you shoot inmanual mode. The ISO chart (Image Noise Chart) can help you in this situation. I will shar...

This 15-patch grayscale step chart has 12 of the patches in a somewhat elliptical arrangement on the periphery and three in an inside row. The relatively large patches are especially good for measuring noise. Supported by the Imatest Stepchart, Multicharts, and Multitest modules. Simplifi...
where σ = noise in pixels, L = luminance (linear), and g is the first derivative of the OECF (the pixel level I vs. luminance curve). g = dI/dL Luminance L is derived from test chart patch density d (which is equal to (-)log exposure): L = 10–d. The numeric formula for...

ISO 的中文名稱是感光度,是指膠卷或感光元件 (CMOS / CCD) 對光的靈敏度。ISO以數字,如100,200,400,800等,來表達感光度的高低。數字越低代表對光的靈敏度越低,不過影像的微粒較幼細,因為雜訊(或稱噪點,Noise)比較少。相反,高ISO對光的靈敏度較高,但成像會有較多雜訊。
