回复 1# 社员甲
看了好几天."老甲"真是"社员",这"会"开的...
第一:中文翻的大错.ISO在一般情下调整的是基准电压.(工作电压,供电电压对于"SENSOR")
"Normally ISO sensitivity adjustment of a camera is performed before digitizing the voltage outputted from an image sensor.
For example, if the ISO sensitivity is doubled, an output from an image sensor is also doubled before sampling, or after sampling. After that, when the development is performed for the exposed image, the brightness of the developed image is doubled."
对电器元件来讲,工作电压是一个范围值.(ISO范围)在两端(极点)使用都会失真.只有在最佳工作点才能保真.
"那么,我们就可以不调节ISO值,而将曝光补正朝“-”侧适当调整,即可获得适当的快门速度和光圈大小。 "
"Now, instead of increasing the ISO speed, adjust the exposure bias dial to the - side, to gain enough shutter speed and aperture. "
GOOGLE的"现在,除了增加ISO感光度,曝光补偿调节转盘的 -侧,以获得足够的快门速度和光圈。"
这个有点废话,欠暴...肯定在"-"区.我想,他是要告诉我们:省省吧,别管那暴光表!
本人理解:在ISO的使用上,在常用范围内使用,不要用极限区,以造成后期的无法挽救.在RAW情况下,既使暴光补偿表在"-"側,也可以选择你要的光圈和速度,而不要把ISO调到极限.这样,欠暴的RAW可在后期调整.
"In case of taking a photograph by RAW, a sensitization is available at development process, and its result is almost the same as the case of increasing ISO speed on a camera. In some scenes, a result would be much better than that. "
"老甲".....再审. |
