>Bits equals available grey levels per pixel That is nice; is this also true when one works in color as opposed to grayscale or black and white? Would I be wrong to generalize this and say "bits equal potentially available tonal levels per pixel" in which the tone can be any hue or color?
However, the question in issue, I believe, was not the meaning of "bits" but if "bit depth" was intended to be a measure of "dynamic range" or of "density range, of the "contrast range" from white point limit to black point limit or of the ability to discriminate between shades or tones within that contrast range, or more generally between the quantity of informational data regarding highlights and shadows and the quality of that information in terms of determining details precisely within that contrast range. While I am inclined to agree that from your definition or mine of "bits" the reference of "bit depth" should be apparant, it does not appear to be in regards to its actual usage, which I believe is what gave rise to the discussion. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of dickbo Sent: Saturday, June 08, 2002 3:43 AM To: [EMAIL PROTECTED] Subject: [filmscanners] Re: opinions?

Just out of curiousity and in simple layman's terms, what do the number of bits that the converter has have to do with if not the density range? How does it impact on what is captured? Austin, I am asking a serious question here out of my lack of knowledge and sure would appreciate a good discussion in layman's terms so that I can understand what is being said without having to hire an engineer to interpret. It has always been my understanding, rightly or wrongly, that the higher the number of bits the more detailed or refined the informational date captured from the original that is transmitted as data in the digital file with respect to highlight and/or shadow detail with the density range figure represetning the range of contrast that can be captured. In other words, "dynamic range" representing the contrast range of the capture's capabilities, while the bit depth represented the quality of the data captured within that range particularly the extremes. If this is wrong, please explain where and how it is and provide me with a more accurrate description (but once again, I urge you to try and do it in non-engineering terms if possible). -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Austin Franklin Sent: Friday, June 07, 2002 7:13 AM To: [EMAIL PROTECTED] Subject: [filmscanners] RE: opinions?
