Hi all,

Im new to RAW file and I have an issue with Aperture. After editing some RAW file (DNG format) in Aperture, I tried to export them to a tiff format, but the exprted files cannot be opened, the computer said they were empty and their file size were zero kB. I have no problems with exporting to jpeg or from jpeg to tiff.

What happened with my photos? And how to fix that?

Thanks
