Logitech webcam resolution question/issue

I am using WPF toolkit for a PhotoBooth I developed and its working well.
I had the resolution for my Logitech webcam C920 set to 1920 X 1280 (2 Mpix) thinking that was the maximum resolution and it produced useable results.
I later learned it will do 15 Mpix/
I changed the desired resolution to 15XX X XXX (cant remember exactly) and it does create a bitmap at that resolution but the quality seems worse.

Any suggestions?

The specs for the camera say it supports 15 MP but only in photo mode.
I don't know if that means I need to do anything different in the code.
I am simply showing the preview at full resolution on the window, in a viewbox so it fits.
When my timer fires, I render a bitmap from that.
Like I said I get the proper resolution but quality is not good.

Maybe I need to do screen grabbing or something?
I don't know.
