Converting an 8 bit file to 16 bit produces a bigger file with the same information in it. There is no difference. Think of a set of integers 1 to 10 inclusive (1,2 ... 10), then think of the same numbers with 2 decimal places precision (1.00, 2.00 ... 10.00) the numbers are the same, but in the second set you can have all sorts of intermediate values (2.66, 2.67 etc) It is similar with 8 and 16 bit -- the 16 bit allows you to have lots of intermediate values. The benefits -may- come when you start manipulating the file. I've not tried it, but it might reduce posterisation or some other artefacts that can appear for example if you push curves too far. Has anyone quantified the differences? bye for now Keith Cooper =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
