Posted at September 27, 2006, 2:23 pm: Crew... In the digital audio world...when we need to find out if one .wav file, for example, is bit-for-bit identical to another .wav file...we open both files in any audio editor or DAW, reverse the polarity of one of the files; & hit playback. if the files are identical...there is dead silence. (we also have bit meters in some apps that will show bit activity down to a noise floor of -144dB...so if there is no bit activity on the meter w/ the flipped files playing back, it serves as a true analytical test that the files are identical.) So...do we have anything like this in the graphics world? Is there any such thing as a null test for say, two .tiff files, to see if they are exactly the same (contain precisely the same data.) Sure would like to know if there is. I have a color corrected digital photo file that came back from the prepress dept. of my CD replication plant; & I need to be able to check if it's the same one I sent them 6 months ago (& my old graphics mgr. is gone.)
