Cast away in Iceland
Recently I purchased two ND Kood filters (ND4 and ND8) with the intention of using them on my trip to Iceland (October 2013). I experienced many new and interesting places. The plan was to capture slow shutter speed images of waterfalls. While I did record some pleasing images I was surprised at the level of blue cast caused by the filters; I am in the process of attempting to redress this via Photoshop Elements 11.
I plan to return to Iceland; this time I will use the in-camera White Balance adjustment and the pre-set via a grey card! Duncan Steward, Frome, UK We find some filters do cause a colour cast, Duncan, but it should be a one-click job to correct in Photoshop.
