Hey guys,

Just a quick one I've taken a panorama photo and through total noobness I think I have broken it. Could you take a quick look at it for me? Contemplated printing it but not sure about it. My main issue is the LHS sky. Sorry in advanced if I've thrown this in the wrong spot.

Pano attempt at Hearsons Cove

Thanks
Ben.

Pano with a polarizer will do that, because the polarization changes with the relationship to the way the camera is pointing and where the sun is in the sky.

Does it completly break it?

If you were shooting with any auto exposure settings, then exposure may have changed from one shot to the next, causing the sky to have a pronounced gradient in the stitched image.
The actual light in the sky at that time may have been that way too. When you look at a scene, your eyes may not be seeing a piece of horizon and sky that wide, so you don't notice it.
Look at the information (exif) files with the original images, and see if aperture or shutter speed changed from one shot to the next.

Circular Polarizer did somewhat the same thing to me recently on a 7 photo stitch:



Mucked around a little to blend the sky, but it still kinda sucks. Shot in Av mode, not sure about shutter variations.

Shifts in sky tonality are inevitable in true panos, and they are greatly exacerbated when a polarizing filter is used. They can be compensated for in photoshop: first I made a sky selection, then I made a new, empty layer, set to multiply mode and filled with white, and sampled a foreground color from the water, then used the gradient tool, set for "foreground to transparent", to lay in a new gradient of color on the sky. It's not "natural" (in the sense that it doesn't *really* look that way in nature, but if *does* even out the variations in tonality.
