They're great, Rob.
I'm going to have to get myself one of those Q thingies. I do love the apparent perversity of putting contrast filters on a digital camera.
We have been under a complete blanket of the stuff here all day and I spent a while this morning indulging myself in 'lone tree in foggy field' photography - one of my favourite pastimes.
As the other gents have said Rob, fine images conveying the mood, I've recently been able to sample playing with filters on digital cameras, some of your results made me see similarities- filled me with some pride as you are a fine photographer.
You do do Stephensonian murk rather well, young Rob. As I mentioned in one of Wes's shots, I do like the way fog lends calm and quiet to images. Many of these would be very difficult to pin down by year I think. Wonderful.
