Partial Colour

I attended an Olympus workshop at Katoomba today.
It was fairly basic but I still learnt several new things about my camera.

One was how to use Partial Colour. 
It's probably not something I'd use a lot but it's fun and surprisingly effective. 
Certainly much easier than doing it in Photoshop afterwards. That's if you know at the time of shooting it's what you want.
