How to get the couple behind the wooden fence in the key below? The wooden fence is part of the background and the keyer was able to have the couple behind it. Is this feature available in Photokey 3 and how to go about it?

Yep, its fairly simple. You need to add a mask, and draw it in the shape of the fence where it crosses their legs.

Another alternative is to isolate the fence in an image editor, like Photoshop, and save it as a separate layer with an alpha channel. Then you could import it as an Overlay (or as a Layer, in PhotoKey 4). For something as simple as the fence, the mask is probably quicker, but if you have a more complex object that you plan to use repeatedly, creating an overlay from it might be worthwhile.

Either way though, its entirely possible in PhotoKey 3 or 4.

Thanks a bunch. I was messing with the mask tool and it was a good start. I had always wondered what the mask tool is for. I can see many possibilities with that now.

Indeed, masks can of course be useful for cleaning up keys on occasion, but there is lots of other, more artistic uses for them in creating depth in your composite and interaction between the layers.
