I just received a note from a reader recommending the photography classes at Indy Photo Coach. She says: "I've taken one of their classes, and it's fantastic. The classes were small, the instructors were easy to relate to and very understanding, and it was inexpensive." It looks like IPC has several classes coming up in the spring for both beginners and intermediate photographers, and private lessons are also available. Thanks to Sally for the tip!
