However, turn 90° to the sun and you can get fabulous skies with the assistance of a polariser.
Well, it can do a brilliant job, but not all the time. On a sunny day, shooting towards or away from the sun a polariser has little effect on the clouds or sky and that’s because there is less polarised light in those regions to filter out. However, turn 90° to the sun and you can get fabulous skies with the assistance of a polariser. Next time you’re out there with the polariser, use the ‘rule of thumb’. Make a pretend gun with your hand, i.e. thumb up, forefinger out, the other fingers tucked out of the way.
