Novice SLR, how to solve the connection and difference between dynamic range and tolerance

Tolerance refers to the ability of film and digital photosensitive element (CCD/CMOS) to record the light intensity range from the brightest to the darkest!

Simply put, how many apertures or shutter ranges are used to record the scene so as not to lose dark parts or highlights!

This range is determined by film or CCD/CMOS and cannot be changed!

In most cases, the correct exposure is to ensure as many details as possible, but if the contrast of the scene is beyond the allowable range, you must choose to ignore highlights or dark parts. However, according to the needs of creation, within the tolerance range, the dark parts can also be lost into silhouettes. The loss of highlights is the worst policy, and the pictures that overflow highlights are very dazzling, unless there is a special need for photos with darker details! Such as portrait photography, news documentaries!

Tolerance: When the eye sees the color scale change from 1 to 100, PS software can display 256 color scales, low-end computers can capture 30 levels, and high-end computers can capture 70 levels, although both high-end and low-end computers are nominally100000 pixels. But in the end, the printer or extended storage can only display 60 levels, and the final effect still depends on the lowest value. It is most appropriate to take scales in music as an example. Let Liu Huan sing on a karaoke machine, and the effect depends only on the machine, not the vocal cords.

Dynamic range: two machines with a nominal pixel of 65438+200,000, one is a 1 10,000 SLR and the other is a DC of 3000, but the original price of each pixel is different. For example, linen bags and silk cheongsam are made of 3000X4000 warp and weft, but why do they feel different?
