HDR Simple allows you to calculate the settings for exposure bracketings for high dynamic range pictures. You just have to enter the settings of the brightest and the darkest point in the picture as well as the number of pictures to take. As regards the number of pictures, you can either choose it or let the application make a suggestion. When making a suggestion, the application tries to apply a light value difference of 2 EV or 1 EV.After entering the necessary information, the application can calculate the needed aperture, shutter speed and ISO value for each picture to take. To make a note of the pictures you have already taken, you can click on the checkbox at the beginning of each row.Finally, the application also features a help page where the functions and requirements are described in detail.
