DeutschPreparing Source Photos for HDR
In order for an HDR image to be composed correctly, all shots must be from the same location. To achieve this, use a tripod.. Even though Zoner Photo Studio includes technology for stitching photos together (see e.g. the panoramas tool), that technology is not used for the assembling of HDR images. This is because even a very small shift in the image during the taking of a shot hurts perspective and thus there is no guarantee that the two shots would be combinable for an HDR image.
Sources for HDR Images
The most common method of acquiring source shots for HDR photos is the use of a bracketing function. Most digital cameras have a bracketing ability. This is a mode where after the trigger is pushed, several photos are taken in quick succession, but with each having a different exposure correction value, at a specified interval away from a "center" value (generally set automatically). When choosing the photos from which to compose an HDR image, it is a bad idea to select those with the most extreme values. The resulting image can then feel too arty, even artificial... almost like a painting instead of a photo.
The use of bracketing has the disadvantage that it does not work on moving objects. The multiple shots involved mean quite a long exposure time overall for the bracketing series. Moving objects thus end up looking blurred. An attractive possibility is to create a HDR from a single shot in RAW format. This is possible because these shots generally contain a wide brightness range. Thus you can extract the needed component shots for HDR out of a single photo in RAW format. You can find a button for automatically creating three pictures and firing up the HDR wizard in the Acquire from Canon RAW and Acquire from DNG windows.
