Boost up picture colors

We're going to make a picture look a bit more lively by enhancing the contrast and colors.

Ope the picture you want to boost up a little.

Press Ctrl + J to create a new layer.

Set the blending more of the layer to Overlay.

This way you boosted up the picture contrast.

Choose the gradient tool (see picture).

Press D to select black for the foreground and white for background color.

Choose the Foreground to transparent gradient (see picture)

Select Linear Gradient (see picture).

And draw a straight vertical line from the top to the about 1/3 of the picture (see picture).

The picture looks much better now.

You can do the step 9 once more if you want even more distinct sky.

And the original picture for the comparison.
