Simple to use

As others have already said, this is a simple to use calculator for when you are using a Neutral Density (ND) filter on your Digital SLR Camera. Dial in the value of the filter (stops) and then set whatever your camera metered as an exposure time BEFORE you add the filter. The readout at the bottom will give you the value of exposure time when the ND filter is in place. The only thing that would make this a perfect application is if they implement a stop watch facility at the bottom of the App so you can time your exposures without exiting the App.

For those reviewers who "don't get it" or are wondering "how on earth do you get the camera to work" - you don't - this application isn't for the Camera in the Iphone or Ipod or even the Ipad, its for serious cameras... :)

Does exactly what it says it does!

This app is useful for photographers who use ND filters on their cameras. It does not allow you to take photographs! The app is very simple to use: simply select your ND filter grade, determine the exposure without the filter attached (DSLRs will tell you this if you hold the shutter button half-way) and the app will give you the required exposure with the ND filter attached. It does exactly what is says it does and for free!

Simply great!

As usual, the iPhone has come to the rescue and another piece of paper with important information on has now been disposed of before it blows away. This is such a simple yet useful and invaluable addition to the photographer's camera-bag. If you're into long exposures, don't leave home without it!
