The Add Images
toolbar button allows you to browse the file
system to add images to your project. Alternatively you may drag
images from the media browser or the Finder to the images list.
HoudahGeo supports JPEG as well as a large selection of RAW formats. Please make use of the demo period to make sure HoudahGeo supports the image format produced by your camera.
HoudahGeo only references files. It does not copy them. Keeping the images safe is left up to you. You should refrain from moving image files as long as you are working on their metadata in HoudahGeo.
