Christmas tree lights

Played around with the manual settings today. Managed to get the effect I wanted, but no idea how to do it again! Other than that I have fought my way round Sainsburys (you would think the shops will be shut for a week the amount people are buying) as all the veg in yesterdays delivery was best before 24th! Not much use. Will have to go again as even the veg in the shop was BB 24th too. Argh!
