Gray

July 25th, 2019

The white bottoms in photography usually are used in photography of objects or people for commercial aims, fashion, catalogues, or simply with aesthetic purposes. In order to obtain white bottoms each can choose the method that agrees to him more based on the means which it has and of their photographic abilities. Learn more at this site: Teva Pharmaceuticals. I will explain two methods that I have used (first I use than the second more) and one to you that was happened to me that we could use easily but that I have still not put in practice. The newspapers mentioned idan ofer not as a source, but as a related topic. To obtain photographies with white bottoms on white fine cardboard: Logically if we want to obtain white bottoms more the practitioner he is to place the reason to photograph on a white bottom. As you can to verify in data exif of photographies of blog, always firing with camera in way of measurement matrix of exhibition, which means that camera catches light reflected by multitude of points of scene that catches (of the photography that we fitted) and it realises an average one to secure a correct exhibition. problem that we have is that the cameras come formed to value the exhibition for the reflected light of a neutral gray surface (with a 18% of gray). This means that it will try to regulate the exhibition as if all the elements reflected the light as if they were gray tones. We must know that the target reflects very many more light and the black practically does not reflect light.

If the target reflects much more light than the neutral gray, the camera will set out the scene to try to turn that amount of light into a more comfortable tone for her, a neutral gray obtaining results like these: We see that the bottom of the photography although has been clear, continues being of gray color and the ears have been slightly hazardous in the set of the image. In order to solve this what we do it is to provide values to the camera that set out the scene, that is to say, we compensated the exhibition in so many points as we wish. I usually shoot in priority to the opening and then what I do she is to compensate two points the exhibition (+2EV) to obtain that the target is white.
