CPL + GND stack

I was remarking to Matt over MSN the other afternoon that of the lot of lens filters I’ve got, the GND – graduated neutral density – one hardly ever gets used. The filter is a bit of a last resort if you are facing an over light bright sky and can’t recover sky detail naturally or with a circular polarizer. The graduation for the Marumi GND filter I’ve got seems to have a semi-abrupt transition between the hard and soft edge i.e. there isn’t much of a gradual blend, The pictures taken in a composition with extreme contrasting in broad daylight can look a little funny, so I’ve avoided using the GND filter.

In any case, I decided to bring it out one early morning just to have some fun with it and to try it out stacked with other filters. I had the Marumi GND stacked with a B+W CPL and on my Sigma 10-20mm. Severe vignetting on the widest end – no surprises there – and the usable images only started at about 13mm onwards. Here’s a quickie shot taken:
