Open Image you wish you manipulate
Now remove the sky so that we can add another amaizing sky into the picture
There are different ways to remove the sky but i will use channels
Go to Window > Channels . On this palette you can see four different layers – RGB, Red, Green and Blue.
Right click on the Blue channel and select the option Duplicate Channel… Make visible only this duplicated Channel
Go to Image > Adjustments > Levels or press Ctrl + L on your keyboard. Set the Input Levels on 128; 1,00; 232 and press OK. You should get something like on the following picture.
White color shows part of the picture which will be selected and black part stays unselected. If you let some grey colors in the picture they will be selected .To make the whole ground black grab the Brush Tool (B), pick black color and simply paint over the grey areas of the water.
Carefully paint over them with white brush. You should get something like on the picture below. On the following picture you can see how the channel should looks like.
Make visible all channels except the one named “Blue Copy”. Go to Select > Load Selection and set the window which appear as on the picture below. Press OK.
