RawHide For Aperture
Free
Love to shoot RAW? Certainly it's the way to get the best out of your camera. The downside is that the files are BIG. Why keep those large master files around if the picture itself isn't amongst your best?
If your Library is bloated with RAW files you don’t necessarily need but can’t bring yourself to throw away, RawHide is the compromise you’ve been looking for. RawHide is designed to convert the RAW files you select into high quality JPEG files while preserving your metadata such as comments, ratings, and locations. RawHide will then tag or set the original's rating to reject.
RawHide will also process your Photoshop and TIFF images. In fact, any image format Aperture can handle will receive the same treatment by RawHide.
We can also automatically generate some smart albums that are very appropriate for processing your converted. See this article for further details and instructions.
