I read many more blogs than I have listed in the sidebar thanks to Google Reader. One of them is Botany Photo of the Day, it provides me with a daily piece of 'eye candy', some more useful than others. Another photo blog I tap into is http://freefoto.blogspot.com/, Ian posts as he travels, but he also re-visits old haunts in different lights and seasons which is what I find most interesting.
