I'm a sucker for great, unprocessed screenshots, and this happy little accident shared by Nivaya Barbosa on Plurk and Flickr takes the cake. The contrast, the lighting, the depth of field, the lush colors of the environment against the muted tones of the dress -- it all just feels so natural even though typically (as most SL artists and virtual photographers know) that natural feeling is one of the most difficult elements to capture.
I will admit that I find myself wishing that her subject, Persephone Paine, was wearing a mesh head purely because they tend to look a little more realistic under indirect lighting compared to the Second Life avatar's vanilla face (like her hands and dress for example.) Then again, even the imperfections lend themselves to the overall effectiveness of this shot. The more I think about it, the more I realize that I wouldn't change a thing.
