How wonderful it would be to just glide around in such a colourful world. I was bored at home without my computer so I tried out an editor on my daughters laptop. Here's has I got this effect, if you play around in any editing software you should be able to get something similar. This works really well with a photo that you may really love, but is out of focus!
First I blurred the picture twice then added a watercolour effect with extra saturation and a very light texture! In pse the watercolour effect is very dark, but you could try some of the other effects light paint daubs and dry brush to get a similar effect.
