| 説明 | This is part of a set of photos experimenting with a new YONGNUO YN 50mm F1.8 lens.www.flickr.com/photos/dominicspics/albums/72157694661082464The much larger aperture available - compared to the kit zoom lens I normally use - enabled a faster shutter, a lower (less "noisy") ISO, and also a shallower depth of field.The lighting colour was often a terrible mix of direct sunshine, blue sky and the very orange colour reflected from wooden table tops. The "colour balance" adjustment tool in a photo editor editor - selectively adjusting highlight, mid-tone and shadow colours was useful in reducing the effects of the sometimes very blue shadows. (Traditionally this type of tool is used to "fix" issues relating to colour film, where the colour of light and dark areas could vary. This is for lots of reasons for relating to the processing and chemistry of film; and also to the physics of photons exposing film grains - for example reciprocity failure en.wikipedia.org/wiki/Reciprocity_(photography) where darker areas for each of the colours present in the shadows may not be recorded proportionately. Presenting the same images in Black and White is another way of "dealing with" [avoiding!] the issue. |
