Measuring Tape vs ND Filter EV

This application measures the shortest (air) distance between point A and point B using GPS, with the maximum available accuracy. Distances are displayed in yards, meters, kilometers, and miles. Simply reset the ruler at point A and watch the distance counters increase as you move toward point B—just like using a real tape measure or ruler. Primary uses for approximate sizing and measuring include: Land, grounds, and properties Real estate Golf course yardage Sports facilities and tracks Air distance Other outdoor measurements The application is intended for outdoor use only and requires location services to be enabled. How to use: Go to the starting point (A) and press the RESET button to initialize the distance counters. Walk to the target point (B) while watching the distance counters increase. The point A arrow continuously shows the direction back to the starting point. You can close the application at any time during a measurement. When reopened, the application will continue the current measurement.

This is a calculator for photographing using ND (Neutral-density) filters with any number of stops. ND STOPS lets you set the exposure without ND filter in a blue field, and see the result below. EV ALTERNATIVES gives you a dual combo alternatives of ISO, APERTURE and SHUTTER SPEED SWEET SPOTS is not always accurate, but in many cases lenses has its sweet spot at about 40% up on the aperture range. SETTINGS lets you choose which stops you want to see in the ND STOPS PAGE and at what EV (exposure value) interval in all pages. To see more apps like this, go to www.discobajas.com
