CORRECTING COLOR IN SHADY SITUATIONS- Watch out for blue light. Believe it or not, but very heavy shade gives off a blue tint. Our eyes normally adjust in high contrast areas, such as going from a bright sunny day, to walking under a large shade tree, but a blue tint does exist in shade. I remember actually noticing the blue tint produced from the shade this summer as we were walking through the park. The brighter the day, the darker the tree, and the more contrast between the two, the more noticable the blue tint. To avoid the blue tint added to the natural skin tones, you have 2 main options. First, many cameras have built in "filters". These "mock filters" come from the days of film when you would actually place a color tinted glass filter on your camera to correct the tint. Now, shade does not produce a large amount of blue just enough to be noticable, so your camera adds a bit of red to counter the blue produced by the shade. Some cameras do a better job than others. If you camera does not have a "mock filter" shade setting or you do not like the results produced, do not fear as you can always add a bit of red to your picture in any editing program. If you look closely, you can see the slight blue tint on the skin tones in the second picture here, I think that I corrected it a bit, but it could use another pass.
