Does the photographer have a website? The best place to find information about a photographer is their own website.
Look for information from art galleries and museums. Try adding "gallery" or "museum" to your Google search.
If you search on the web and find a site you've never seen before, stop and evaluate whether or not it's the best for your research.
Try a library resource!
Gale eBooks would be a great place to start.
Try Explora for High School. Video tutorial here.
