Hello all, My name is Douglas Burns and I used to be a regular on this list till about 6 months ago. I changed jobs then and now work for a typesetter producing the covers for their scientific and technical journals. I work on a daily basis with Photoshop, but my photography is limited to my personal work.
Have been following this thread for a while, and staring to get a bit confused. With all due respect to David Kay I just don't follow his logic. I agree with all the other posts that the dynamic range is simply the difference between the highest and lowest values recordable (hence the term "range"). This is something I was taught on my first day of college (and the reason I'm writing this post in simplistic terms with the minimum of jargon!). The bit rate simply determines the number of discrete steps within that range that the device can record. > Even 1 bit sampling would have the same dynamic range - that > is black or white, on or off. >Yes, but it couldn't record any intermediate tones and that is what we're >talking about - how many f-stops of our SUBJECT data we can capture. To my logic then a device with a dynamic range of say 12 stops would still have a dynamic range of 12 stops whether it was an 8-bit, 16-bit, or 20,000-bit device. Following that logic it is apparent to me that a 16-bit device does not inherently have a higher dynamic range than an 8-bit device. So you wouldn't be recording any more "f-stops of our SUBJECT data" whether you were using an 8-bit or a 16-bit device. Or is it my understanding that is way off?
