【實用攝影app】Filter Calc|最夯免費app-綠色工廠好玩App

Neutral Density filters can help add an interesting aspect to your photography. One drawback with very dark filters is that they often exceed the camera's ability to provide an accurate exposure reading. Filter Calc is a simple javascript based application that takes your metered exposure value and returns the proper exposure time with the filter installed.Simply meter the scene with the filter removed and enter the exposure into Filter Calc. Install the filter and take the shot with the exposure displayed on the screen.
