An amazing tool for teaching photography.
This resource works with a variety of the elements when taking photographs. For instance, ISO and shutter speed. One of the drawbacks is that this application doesn’t offer the viewer to roam from left to right to capture a variety of compositions. However the application on focusing and framing does such a task! The method and theory seems simple enough once someone explains it. Great resource non the less and it is free!
