When you book a photo session through derksen photography your initial session fee includes a proof book. The proof book is a spiral bound collection of 4×6 prints (a 4×6 of each photo that is presented in your online gallery). So, essentially, your session fee actually includes one copy of each picture in your gallery. What a deal! 🙂 Below is a sample of what the proof books look like. The proof book will help you to see what the pictures would actually look like in print, rather than just on their computer screen before you make your print purchase. Why not develop a little collection of derksen photography proof books? :).
