My problem is how would i be best to alter the light changes in the water ? Is there an easy way in Photshop! It is my first attempt at a panarama and i feel every time i look at it the light change strips where the stitch takes place just seems to stand out even more !

Any help on a fix for this would be great !

Thanks

That's quite a challenge. Try selecting the area that is overexposed, then do a light adjustment on the selected area to match your darkest areas...repeat for any other areas. Somehow, you will need to make a selection with 'soft' edges so the transitions will look okay.

The next time you take a pano, turn off the program (go manual) so that the camera does not re-meter as you pan...aim for a fixed meter value...perhaps the value you get from spotting the trees. I'm not an expert in panos, but my best guess is for you to aim for a fixed meter value throughout the shot...that way, you won't need to adjust it in photoshop. Also, use a hood to make sure stray light is not influencing your meter.

This is a difficult problem to deal with satisfactorily. It's best to avoid the problem by giving each image the same exposure using either manual or autoexposure lock mode. Even then, problems can sometimes arise with fluctuating light conditions. You could try using an automatic stitcher that does a better job of blending images or which permits manual adjustment of image brightness.

Another solution is to stitch the images with Panorama Tools. This has the big advantage that it will output the stitched image as a layered PSD file with masks, i.e. each image is left on a separate layer. It is then easy to adjust the brightness of each image to achieve a perfect blend. Moreover, you can adjust the line of the seams to deal with problems caused by the waves not matching on successive shots. An extreme example of dealing with waves is shown here: http://homepage.dtn.ntl.com/j.houghton/waves.htm .

I switched the red mask on (which shows the image boundaries) to show how one seam has been bent around the wave features to disguise the join. Note also the large amount of feathering introduced into the seam in the area of the sky, using the gradient tool on the mask. Another advantage of Panorama Tools is that it will handle a tilted camera. The horizon in your panorama is curved downwards at the sides because of the downwards tilt of the camera. Pano Tools will enable you to correct the curved horizon and get vertical features vertical. Pano Tools is not the easiest stitcher to use but it's very versatile. If you want to give it a try, see the beginners tutorial at http://homepage.dtn.ntl.com/j.houghton/pttute.htm .

Hi

The water was the only thing I knew the photo was stiched.

On photoshop: Use the lasso tool highlite the lighter water, go to levels, slide the leveler until the light water was as dark as the darker water. And keep on doing that until everything is equalized.

Thats about all you have to do. Make it darker not lighter using levels.
