Does HoudahGeo support RAW files?

HoudahGeo supports JPEG as well as many RAW image file formats.

HoudahGeo may read all the same file formats as Apple's iPhoto and Aperture.

For writing EXIF, XMP & IPTC tags, HoudahGeo relies on Phil Harvey's excellent ExifTool. You may check this list for file formats ExifTool can write to.
Please use the demo version of HoudahGeo to try with actual files from your camera.
