Brightness variation message and overexposed result
Posted: 19.01.2010 17:00
Just used Helicon Focus for the first time. Everything seemed to work as expected. Took a series of images of a seashell with lots of surface detail on a dark background. Used manual exposure and each shot (measured in Photoshop) is the same brightness. After running Helicon I get a message saying that brightness varied by 85%. The resulting image seems way over exposed and there is no detail in bright areas but edges are sharp throughout. The seashell is about 200mm deep. Used a 180mm macro lens. Moved the camera on a Novoflex sliding base but did not change the focus setting on the lens. Is my technique wrong? Should I keep the camera stationary and refocus the lens for this type of macro image? I notice that as the lens moved closer to the subject the image size in the frame increased noticeably. Any advice please. Geat product when I learn how to use it.
