yeah there's a help section next to the exit button. but I haven't really described what the B&W filter does.

Essentially, that screen is to be viewed as filters placed in front of a lens shooting B&W film. It extracts the tonal data (decomposed RGB) of that color and re-creates the photo using only that tonal content. For instance if you have a photo of a red car and a green tree, click on the red button the tree will fade away into some bland gray, but the car should pop out (the way it would with a red filter) if you do the opposite and click on the green you'll see the tonal variations of the tree and the car will be "under-played". Using the correct filter can make crappy images at night or elsewhere really pop and become usable.

At least that's the intent.


Ha I just got that joke, I've never been to Brussels
