Panorama Help

[sgood]

I shot this panorama with a Digtal Rebel. Manual mode. Three shots assembled with Photoshop. The exposure from each shot came out so different that I get diagonal lines where the photos overlap. Any advise how to correct this problem?

I usually get my best results using Panorama Factory (http://www.panoramafactory.com/). It blends the images to make the seams less visible when the exposure wasn't locked. Give it a try and see if it helps in this case.

if each section is on it's own layer you can make a curve or hue/saturation adjustment layer over the layer you want to adjust then alt-click between the two layers and the adjustment layer will only affect the immediate layer below it. choose which section has the exposure you want and make individual adjustment layers for the other two to match them up.

Any advise how to correct this problem? BTW, if you were in manual mode the exposures should've been all the same. I think what's causing the seams is the auto white balance. When shooting panos you need to disable every auto feature (including AF).

You need panorama software. It will correct the exposure issues, make geometrical corrections for your lens and make you breakfast in the morning.

The best software (IMO) are based on the free Panorama Tools libraries.

Two choices:
Inexpensive: http://www.tawbaware.com/ptasmblr.htm
A little more $$ (but worth it): http://www.ptgui.com

both of those apps will use the free plug-in "Enblend" which will do a final clean-up of visible seams.

Programs like Panorama Factory deal with simple panoramas well but when you have multi-row panoramas, up or down tilts (like looking up at a mountain), alignment problems, exposure issues or lens distortion then you need a bigger hammer.

There's a great pano forum here:
