Sorry my English is bad, I’m Belgian. I have to say I’m new to all this , log etc. I’m in a Film school in Belgium.
Often on forums and informations about Log encoding I see that it allows to allocate more code value in the range of shadows by giving the equal number of values in each stop of dynamic range. I think I understand the principles of Log Vs Lin. The fact is linear encoding gives too much code values to the highlight where the eye is not able to see the tiny changes in brightness in the higher stops.
But I’m not sure, I understand everything. If the ADC in most of the sensor is working in 16bit linear, so the 10 th stop under full well capcity has just 64 code value. I could do 12 bit log and have about 300 values per stop (I know, It’s not exactly equal but it’s to make the point) but I’m wasting many values since the 64 values I got is all I can get, right?
Is that possible to have an ADC that quantizes the analog signal directly in log, would it be better?
I red a lot on this forum and on websites but I’m not sure I’m understanding it all. I am not an engineer or anything, I am just curious of understanding the process, If someone could enlighten me?
