Comments: We have a couple of problems here that allow me to state right away that Velvia 50 wins this color. First, the background was the yellow exterior of my house. Which one appears yellow to you? Also if you know Hydrangeas, you would pick Velvia 50 as the truer color. There was obviously some source of reddish light just outside our visible human range that the E100VS is picking up. I like that color, but I know that it is not the correct color. Remember, some films can "see" outside our human eye's visible range. This will affect the color balance.
