Also Erwin, What lenses do you usually use for your images?   

I use Canon 16-35mm f2.8 mkll for most of my Landscape shots Oksana.

For Canon users that are in the market for new lens, try the Canon 16-35mm f4 version, it's sharper and cheaper than the f2.8. But, if money is not an issue, the new Canon 16-35mm f2.8 mklll is the best way to go 🙂

Beautiful light. Love silky water and the sky. What company filters do you use? Did you ever noticed that stacking three filters degrade quality of the image in any way (like sharpness) etc?   

Thanks Oksana. I'm using Lee filters.

With my setup right now, I don't really notice any effect with stacking 2 or 3 filters. The only thing I noticed before when I was using a different filter brand was color cast. I heard Firecrest 10 stop ND filters are good because they don't have color cast. Lee's big stopper has a blue cast as per my observation.

Filters used: CPL, 6 Stops ND Filter, 0.9 GND.
