I have 3 very different yellow entries for this week's Headbangers' Challenge. The first one is one of my very early attempts at light painting. You 'simply' set fire to some very fine wirewool and insert it into some form of apparatus so that you can spin it around very quickly whilst your camera is on long exposure. The second one is actually one from the cutting room floor from my motion freezing exercise a couple of weeks back. I tried a few different colours but eventually decided I liked the blue most, but taking another look at the yellow one and I quite like it. The third picture is of some flowers, plain and simple. Don't know what they are, but I know that I like them and they are rather photogenic.
