Well, you don't say where your hotel is located. Hollywood Cemetery is a great place (that would be my first recommendation), the James River in the downtown area has some nice rapids and rock formations, Monument Avenue and The Fan district have some interesting subjects (buildings and statues), as 2F/2F said, Maymont Park, has some nice gardens, although I don't know how nice they would be this time of year, Lewis Ginter Botanical Gardens, the University of Richmond campus has some great old buildings and nice grounds, The Virginia House, Agecroft Hall, there are lots of Civil War battlefield parks, Carytown (if you like street photography) can have some really interesting subjects.
