I had my argus negatives scanned as TIFF files at Bay. When I started processing them I noticed that the files seemed to have less dynamic range than the raw files out of my pentaxen. I also noticed how much the grain looked like digital noise.
I did some poking and prodding and discovered that the TIFFs are only scanned at 8 bits, which surprised me, because I expected at least 12. Am I unusual in that I'd want more latitude for post processing out of scanned negatives? Or is it just assumed that they adjust the exposure of the scan to the negative (though some seemed under or over by a stop or so) and the extra bits aren't needed? Or is 8 bits all that there really is to film? to get more you'd need a nonlinear conversion in the under and over exposed areas? -- Larry Colen [email protected] sent from i4est -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
