NDCalc2 vs Neutral Density Calculator

Screenshots are german but it's translated to english too. This is a completely rewritten Version of NDCalc - now called NDCalc2. It's all new with these great features: - build for iOS7 - supports the 4" Screens of iPhone5/s/c - supports retina - Much more comfortable selection of shutter speed and NDFilter (no wheel control) - Multi-Select! Finally! You can switch to Multi-Select-Mode with a single tap in the toolbar if you are a ND-Filter-Stacker like myself :) Just activate Multi-Select-Mode and tap on any Filter you have stacked to the lens for really long exposures. - Add your own Filters! Finally! You own a filter which is not listed in the default list? Just add it by f-stops, ND-Value or Factor. - Delete Filters. Just delete all filters you don't own and make selecting filters much more convenient - Reorder Filter. Order the Filter-List as you like it. Bring up the most used filters to the top of the list. The core function is still the same as NDCalc: You know the time without the filter -how long do you need to exp. WITH filter? Sounds easy but tell me quickly how long to exp. with an ND 1.8 if the time without filter is 1/320? Now you can! Set Filter and exp. time without the filter and you can see the correct time. In the example above 1/5 Even easier it shows you 5 because this is what you can set on a dSLR. Smaller letters showing you the actual time. For 12500'' it shows, that these are 3h, 28m and 20s. For times of 4+ seconds you get a countdown button to easily stop longer exposures manually with a remote shutter release with alarm and vibration (if supported).

Neutral Density Calculator for photographers to calculate the shutter speed when adding neutral density filters to your lens. Set the filter you are using and the shutter speed without the filter and the app calculates the new shutter speed with your filter fitted. This is a utility app that helps you determine the correct exposure time/shutter speed when using Neutral Density Filters. Instantly it tells you exactly how long to leave your shutter open, and it even has a built-in timer countdown clock. Features: - User friendly UI - Includes a countdown timer if exposure time is more than 60 seconds (bulb) - Option to dim the screen while countdown - Option to enable disable sound once timer reach - Neutral density or Optical density unit selection - Supports up to 20-stops of ND filter - Base Shutter speed from 1/8000 - 60 sec - Show Fractional transmittance data with selected ND filter Steps: 1 - How many stops your ND filter is (like a 3-stop, 4-stop, 10-stop, etc.) 2 - Base shutter speed - What your current shutter speed is (before you put your ND filter on your lens) 3 - Final time are calculate base on your input, you can press the start button sync with DSLR/DSLM camera shutter at the same time. And the timer will remind you once timer reach to release your DSLR/DSLM camera shutter. Thanks for your support and do visit nitrio.com for more apps for your iOS devices.
