Perfect Exposure Reviews

Awesome exposure calculator

Super useful for studio photography and or using ND filters. The exposure calculator is an awesome tool that lets you compare one set of exposure settings to another. I wanted to use it for my studio lighting setup where I knew what settings provided a properly exposed shot and I wanted to get an ND filter in order to shoot a wider aperture. This app allowed me to figure out what ND filter was necessary. Only improvement is I wish the range of selectable ISO went down to 50 instead of 100 being the lowest. Not worth subtracting a star for this excellent free app.
