Enhancing a washed out sky
If you have a sky that lacks signficant contrast
or definition in relation to the rest of subject matter in your photograph,
it may be because the dyamic range of your camera was unable to preserve
sufficient definition while also trying to retain enough detail in the
foreground of your image. The technique below provides a means for improving
the sky definition independent of the rest of the image. For this technique
to be successful you will want to avoid any telltale halos that may appear
on the horizon if you overdo this processing. Pay particular attention to
steps 5 and 6 with this approach.
- Duplicate the
background layer.
Menu: Layer -> New -> Layer from background.
or
In the Layer palette, drag the background layer down to the new layer
icon.
- On the background copy, select the sky via the
“Color range” tool.
Menu: Select -> Color range
Use black matte to identify your selection and move the slider
accordingly.
- Turn the sky selection into a layer mask.
While the sky is still selected, In the layer palette, click on the “add
layer mask” button
- Enhance the sky by changing the blend mode for the
new mask to “multiply”
Use the layer palette selecting the “multiply” option of the various
blending modes available.
- Adjust the blending between the sky and foreground
to avoid that distinctive photoshopped halo. This is done via using the
Gaussian blur filter mode. With the filter mask selected:
Menu: Filter -> Blur > Gaussian
blur
Slide the radius bar to your satisfaction.
You
can also apply the same basic technique to enhance the foreground.
For example if the foreground is too dark, you can apply the same steps
above on a separate copy using an inverted mask to select the
foreground. Then use the blending mode “screen” instead. Use the opacity
control to vary the degree of lightness.
- Adjust the opacity on the new layer to control the
degree of impact due to this enhanced sky. Too much can very garish and
unrealistic, also resulting in a telltale sharp border at the horizon.
The biggest challenge with this technique is controlling the edge of the mask
where the sky meets the horizon. Sometimes skipping step #5 produces better
results. Alternatively with the mask selected you may want to play with
the edge via the 'Refine edge' under the select menu. This edit capability
allows you to move the edge of the mask, feather it, or round the sharper edges.
In a way, it allows you to create the equivalent of a softer gradient between
the layers.
