I need a sky!

I’ve just stitched a beautiful panorama of Italian mountains , Alpi, all covered in snow. Unfortunately the sky, clean blu till 2 hours before, was quite cloudy.

I need a sky to use instead of the original. I’ve already masked the image, but where to find a sky in very high resolution, and with a perspective of a 180° panorama etc etc…

It’s quite difficult… maybe it exists a program able to render the sky in a customizable and natural way.

any idea?

Is there no sky where you live?

BTW, I doubt it will work well. The light on the landscape will still look like it was in cloudy light. That will look weird with a sky that doesn’t reflect that.

I find the Match Colour function in PS CS2 does a pretty decent job of matching the lighting of 2 different image elements if it’s used properly, along with some careful dodging and burning. Read up on the function before diving in, and you should get acceptable results.

To the original poster – there are some high resolution panoramas available at www.istockphoto.com that might suit your purposes. They don’t cost that much.

I’ve seen an ad somewhere for a whole CD of sky pictures. Sorry I can’t remember where but Google should probably be able to help you.

I’ve been carrying a not-quite-P&S digital camera around for about a year and whenever I see a really nice sky I pull it out and take a shot at its highest resolution. Pretty soon I’ll have my own library of sky with and without clouds. Suggest you do the same.

The issue is shadows, Mike. Overcast == no shadows.

Oops – I’ll remember to read posts properly in future 🙂

The clouds don’t obscure the scene, becouse they were just arrived and the sun wasn’t covered yet.

So this isn’t the problem, what I need is a gallery of sky picture.

Is there no sky where you live?

unfortunately I live in Milan and it’s quite impossible to get a panoramic sky view, and the sky isn’t exactly like a mountain’s one ….

if you have some helpful link…

I found this gradient that’s perfect for alps.

but how can I use it in my picture? I tried to reproduce it with gradient, but I can’t get it the same of the original.

Man, you have to work at it. Make your own, then play with the sliders and color.

I shoot my own skys all the time. Finding a suitable panoramic of sky, especially of 180° might prove to be time consuming.

Getting some sky shots both day and night when the opportunities arise should be part of the landscape shooting process. Hell, you’re there anyway. Grab a few frames of sky while you’re waiting for the light.

That doesn’t help you -now-… but it may in the future. —-

How does Match Color or dodging and burning add or subtract shadows. If you don’t have any shadows in an outdoor picture, it was obviously taken on a cloudy day. If you put a cloudless sky in that picture, you still don’t have any shadows. I suppose you could paint them in, but you could also paint the whole picture.

The human eye is very good at picking up such inconsistencies. Not everyone will know what the problem is, but almost everyone will know that something is wrong.

Then again, there are lots of photographers who you would think have trained eyes that do some weird things. It always bothers me to see pictures of full moons in sunset pictures. A photographer should know how light makes shadows due to the direction of light, but they lose it on the moon. The light direction will never allow a full moon in a sunset. Well, until we have two suns anyway. For some reason, photographers and others miss this all the time.
