It’s sometimes hard to find images fitting to a certain challenge. For these tasks, I’m using the help of Excire Foto. I told the software where my image library is located and it starts analyzing the images. It recognizes the main colors in the images as well as the contents (what is in the images) and tags them automatically. Later, I can use the user interface to search for images with certain tags. Currently, you can save a few bucks when ordering Excire Foto, because it’s on sale.
