I must admit I did groan when I arrived at one of my favourite locations in Sutherland Scotland at the edge of Loch Hakel to ponder a clear twilight blue pre-dawn cloudless sky. I hope though I have managed to make some refreshing lemonade from the sour tasting lemons originally dished out. Staying resolutely positive I endeavoured to make the best of it. I took this just as the very first rays of sunlight struck the waterlined satelite rocky moraine turning them to burnished gold in an ocean of sapphire blue both above in the skyand below in the loch. I used a shutter speed and ISO to render the speed just fast enough to maintain the inegrity and definition of the bubbles but long enough to soften the water surface ripples. I hope it works for you.
