Photography podcast #59 talks about HDR (High dynamic range) photography in an interview with fashion photographer and HDR instructor Joseph Cartright. In this podcast we discuss how to create an HDR photograph and be warned, this is an intermediate level podcast. That said, Joseph reviews many of the terms that confuse digital photographers these days, so part of the podcast (especially the beginning) reviews concepts relevant to all digital photography. In a nutshell an HDR image is made of 2 or more shots where the same scene is photographed with bracketed exposures and then put together with software in order to extend the dynamic range (get additional information in the highlights, midtones and shadows) of the scene.
Here’s a few terms as explained by Joseph that are good to absorb right away;
– Latitude — Refers to how much you can be ‘off’ of the correct exposure and still have a usable image.
– Dynamic range — Refers to the usable range of data you can capture between the highlights and the shadows before you lose data. (If you overexpose too much there is no data in the whites or highlights and if you underexpose too much there is no data in the blacks or shadows).
