I've tried many things to get Aperture to export some sort of usable file when I do a "export-> Master"
The command seems to work, it creates a file of the proper name. The output is about 4K in size, and when I try to open it, every programs says is a broken or illegallly formated TIFF file.
I've tried all of the options for including and excluding metadta from the export dialog box. No joy.
What I want is a file similar to the RAW (canon format) or the scanned TIFF file that went in.
