How many stops of dynamic range do you get in jpeg that is different from antone else? Jpeg is 8 bit no matter how many stops you get in rawShooting JPEG you will never see a difference
For a linear DR it is a DR of 8 - which is why specialist printers are needed to get more.
I hate to say anything critical to anyone, and you are both correct. JPEG has 8 bits of data per channel. And a statement involving the word "it" can always be assumed true--we have no idea about the object to which "it" is referring.
However, you are saying something correct and then jumping to a completely unrelated conclusion. Here's the missing information:
* JPEG is not encoded with linear gamma, and never has been with any digital camera.
"If images are not gamma encoded, they allocate too many bits or too much bandwidth to highlights that humans cannot differentiate, and too few bits/bandwidth to shadow values that humans are sensitive to and would require more bits/bandwidth to maintain the same visual quality."
* One bit and one stop have nothing to do with each other. It's also completely ridiculous to define dynamic range in terms of bits--it is only meaningful if defined in terms of stops.
If you have ever taken a class about encoding mechanisms, one of the first things one learns is, "The first thing to remember is that bit depth and dynamic range are NOT the same thing. It is going to sound much the same, but it's not."
The terminology used on this forum is sometimes as silly as someone saying, "I am going to itch my mosquito bite" when they mean "scratch my mosquito bite."
If you have ever taken a picture with part of it dark or part of it bright, you are seeing the effect of dynamic range. It has absolutely nothing to do with the file format. RAW extends the dynamic range provided that the same gamma curve is applied in the image encoding.
An increased dynamic range in the camera has a proportional effect on the dynamic range of both the JPEG and the RAW image. You can understand this if you will be patient enough to consider the example of an interval of real numbers.
The RAW image corresponds to the interval [-x, x]. The JPEG image corresponds to the interval [-cx, cx], where c is between 0 and 1. A change in the dynamic range corresponds to a change in x. The effects on both the RAW and JPEG images are proportional to one another.
One good article to read is this one:
It also talks about noise in addition to dynamic range. There are books to read about this subject as well.
