Here I used Lightroom’s graduated filter to darken the sky area and to lighten the grain field. I think it really is a great tool to give extra punch and drama to your shots.
LR’s graduated filter is much faster to use as Aperture’s brushes are. I can achieve same kind of a result by using Aperture’s brushes but it is so much slower process. With LR those adjustments took only few seconds to make and what is a big plus is that you can make multiple adjustments at once with LR’s graduted filter or brushes. With Aperture you have to select a new brush for every single adjustment.
