I am an ecologist who dabbles in fine photography. I also do a lot of shooting to record the plants and animals I see and to collect images to help others learn to ID plants and animals, such as you might have in a field guide.
I am finally getting around to tagging all of my images (in Aperture) and I am wondering what people use as keywords for nature photography. Right now my current list of keywords is: scenic, bike, travel, wildlife, people, plant, insect, arthropod, fish, herp, bird, mammal, fungus, geology, fire, fruit, habitat
Are there other categories I should specify with additional keywords? I would love to see other peoples lists of keywords so I can get some ideas.
Also, for plants and animals I have the species names in the "Object Name" field but for plants and insects I would like to broaden this a bit by recording the Family or Order of the organism. Is the keyword field the best place for this, should I make a custom metadata field or is there a better place for this?
