Experimental daff
I've been playing with the functions on my camera again. This one allows me to extract all colour except the one specified - in this case, of course, yellow.
In other news, we extracted lots of blanket weed from the pond, and found several newts in the process - but of course I didn't have my camera with me. We've now added some stuff (little beasties) that extracts the nitrate from the water, and thereby suppresses the growth of blanket weed.
