Kemal did a great job leading our private photo tour. He took us to several "secret" places off the beaten path and was very knowledgeable and helpful on how to get the best shots. He was flexible and wanted us to see (and shoot) the things we wanted instead of taking us to where the guidebook said we needed to see.
If you are a serious amateur photographer, you can learn a lot from Kemal about photography plus get to see interesting places in Istanbul. He offers a variety of tours to different parts of the city so next time we are here we will try another one of his tours.
