A genuinely friendly and informal web community where you can learn about photography as your skills progresses. A place to visit especially if you are just starting out. It's almost like moving into a village filled with photographers! You can ask questions. Buy and sell. Post lost and founds. Answer questions. Offer neighbor to neighbor advices and review your favorite photographic stores and equipments. If you put all that you know there that information will never be lost and will always be searchable in the future. It's a healthy community you'll sure to love, try it :)
