changing a grey sky into a blue sky


Hi,

I have a question concerning an image I took while in the mountains. I have a beautiful shot of the mountains except for a rather dull grey sky. Unfortunitely I was not able to be there on the right day. I want to change the sky to a more attractive looking blue sky. Is this possible in photoshop.

Thanks for the help
Andrew Tattersall

  Yes, you should be able to replace the sky.... Do you have a sky you want to replace it with?

Andrew J. Tattersall   Yes I do, should I crop it or try and make the colour?

  You can copy the image onto the sky as a new layer and then select and delete the old sky.... or something along those lines...

  Is the local close enough to warrant another trip when the sky IS blue?
(Just a thought.)

  That's always a safe bet... I've done that many a time...

  You could do a graduated tint in picasa over the sky. It is really a shame that you have to change it BACK to blue, though.

anonymous A.    It is a pretty regular task, Andrew... I have a file of skies that I am always adding to for just that purpose. That way I can match time of day, direction of the light, cloud formations, mood, tonality etc.

There are lots of ways to go about it, but I think the most natural results are achieved by duplicating the background layer of your original image, then dragging the image with your sky into the software (or copying it and pasting as a new layer), then placing the sky layer between the two existing layers.
Now, select and delete the sky on the top layer. On the middle (sky level, adjust the image until it is properly positioned. You will probably find that you will now have to touch up the top layer margin to make the sky look right...do the=at, but don't worry if it's not exactly right. When you are satisfied, select the empty sky on the top layer, select the middle layer, invert the selection, then hit delete. Reselect the top layer, Invert the selection again, Merge the top and middle layers then go to the bottom layer, feather the selection (about 6 pixels)hit delete again.
Finally, back on the top layer, cycle the Blend Modes until you get the result you want...probably soft light.
Sounds complicated, but in practice it's about 10 minutes work and a lot better result than many other "simple" methods.

  something I'd like to point out is that blue sky often warrants deep shadows since the sun is shining. just replacing the sky with a blue one I think could give it an unnatural, manipulated look. I can't see the picture, so that is your call, just pay attention to that if you do replace the sky. I like the idea of slightly tinting it, or, replace it with a stormy sky if that would look more natural, since both are 'cloudy' and do not render deep shadows and highlights as a sunny, clear blue day would.

Andrew J. Tattersall   Thanks for the suggestions,

I have since started a folder of different sky shots. I have also found the more I work on images the better you get. Thanks again.

Andrew
