User Reviews

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.
