Subject: Re: Camera Raw Post-Conversion Features
Now you have me confused. Perhaps we are using different definitions. When I use the words "non-destructive" or "lossless" I use them in the sense that any transformation is unambiguous and reversible. For example, if you wish to convert one value into another you could apply a transformation like y=2^x. It is trivial to reconstitute any value of x given the value of y. So it seems to me to be impossible to consider either sharpening or noise reduction as non-destructive because each requires a selective alteration of some pixels based on neighboring pixel values and this process is not mathematically reversible.
The thrust of my original question, then, was which tools in ACR are "lossless" in the sense that no informational content has been so altered that it cannot be reconstituted from the TIFF file
