Magenta Sky and Photoshop

[CaraRose]

Okay, I took a shot of the mountains in the Smokies and wound up with a sky that was magenta tinted rather than blue. I played around in Photoshop with hue and saturation and tried to get the sky more blue... I'd like to know if it looks unnatural now or it it helps

Also, could someone explain to me what causes a magenta cast over the sky? Is it something with exposure? It's a little more intense on the scan than in the print, but it is very clearly magenta still in the print.

I don't have a polarizer, just a UV-haze filter.

Thanks all!

Since you were using film, I would guess that the neg fooled the automatic printer when it was deciding what filter pack to use. You should be able to return the print with the neg and ask that it be printed again - manually if necessary. If you had been shooting digital, I would have thought that you may have had the wrong white balance setting.
What film were you using? Was the whole roll tinted this way? If it was there may have been a mistake in development.
Here's a copy of your original that I used Paintshop Pro 7's Automatic Color Balance tool on.

If you want to color correct this, correct the sky only (and maybe a part of the haze), use a soft selection or mask, but don't correct the complete image. Then make a second correction for the foreground, again, using a selection.
