The difference between day and night

I decided to take a break from knitting to snap a shot of the socks I'm working on. Out of curiosity, I took one picture with the "Auto" flash . . .


. . . and one with the "Night time" flash . . .


. . . The flash makes the difference between blue and purple which is the color the socks are.

These socks are based on a pattern being worked up on the Six Sox Knitalong group on Yahoo!
