I used a piece of white paper as a diffuser glued with adhesive tape on the flash.Manual exposure mode (M) fired in format manual RAWEnfoque (MF) composition UV rays protection filter: A simple composition, respecting the rule of thirds. Place pepper on the right and the vertical occupying branch photography left side to not allow excessive black devoid of interest. The exposure values: finding myself as close to the pepper, needed to close the aperture to achieve that all or nearly all focused appear (yet lack something of focus on the twig holding it). This is why I chose an aperture of f/16.A opening start from here went by selecting other values taking into account that they were the 12 noon and I wanted to get a black background.To get a black background we have to do is force the camera to not capture anything of natural light (from sunlight) and illuminate what we wish it to appear illuminated by artificial light (from flash).Let’s go by parts, we ignore for the moment the part of flash. Let’s go by parts, we ignore for the moment the part of flash.Achieve a picture by eliminating natural light is simple. Simply close the diaphragm (in this case f/16) and decrease the exposure time. We got a photo underexposed, black, no light.In this case perhaps with the aperture to f/22 and ISO 100, a correct value (to achieve a properly illuminated with natural light photography) for exposure time would be 1/2 seconds or even a little more.Then that we do, we have a short time of exposure, in this case 1/200 seconds and check that leaves a practically black photography, tremendously SUBexpuesta, eliminating us natural light.
The Iluminacionla flash light fires in a fraction of a second (1/500, 1/1000 or one thing by the style) and therefore only affect exposure during that fraction of a second illuminating everything at your fingertips. I mean, if we lighting an excena with a flash, although we are exposing 30 seconds, the flash will only affect those 30 seconds during the split second in which fires, the rest of the time the camera will only capture the natural light.
