panorama help

[ahmadof]

i'm using stitcher that came with the canon software. it works great for aligning photos correctly... even without tripod. The seams are all visible, however, because of slight color differences between the segments. i.e the sky is slightly more blue in one shot compared the one just beside it. does anyone know how to deal with thos?

I also have had that happen when I have just taken sequential photos and then used the stitcher program to put them together. When I have placed the camera into 'stitch' mode using the mode dial I haven't noticed any difference in the sky color. My camera is the S30. I don't have a lot of panorama experience, but the results when using the camera's stitch mode and then using photo-stitch software to put it together seems to work best for me. I don't use a tripod for this, but its on my wish list. I gave up trying to even out the sky color on the photos that I hadn't used the camera's stitch mode to take.

The more photos you use to stitch together the more gradual the sky and colour will be.
If your panoramic photo is 3-4 photos stitched and you notice a colour change as you mention then try to get the same size pano but use more photos.

I had the same problem.

What worked for me was to ***MAKE SURE*** that ALL of the settings are the same for each of the parts. Same shutter speed, same apeture, and MOST IMPORTANTLY, I manually set the white balance to the same color temperature.

As I thought about it after the fact, it made sense. Since I am taking, in essence, ONE photo, the settings should, of course, be identical.

Having setting exactly the same is not always necessarily true.
There will have to be compensation for lighting as each photo
comes closer to or farther away from sunlight.
Below are photo taken to make up a panorama photo. The first
two identical then exposure changes with the third photo. The forth
being the same as the third.
The final panoramic image is last. As you'll see the pano could
likely have been done in 2-3 photos but the added photos made a
much nicer transistion.

Many automatic cameras have an exposure lock feature for giving each image the same exposure, otherwise use full manual exposure with the same settings. Set the exposure so that it's correct for the brightest part of the scene. This will work for most panoramas, though shooting directly into sun with a 360 degree pano poses special problems.

I've had some luck fixing seams in the sky using the clone stamp and smudge tool in Photoshop. Select one of the more feathery clone brushes and stamp back and forth across the seam. After that, smudge the area a little. Next, do your color adjustments to the sky. This process is more of an art than a science so you might have to practice it a bit. The trick is to break up the line the seam forms. If you can transform the seam into a blury curve, the eye doesn't pick it out as easily as it spots a straight line cutting through sky.

Here is a panorama that had five seams in the sky. Can you spot them now? If you look really close you can, but at a glance they are invisble. It's preferable to shoot panoramas that don't have seams to begin with, but this trick can save an otherwise ruined panorama.

Another way to deal with the problem is to balance the images before stitching by using the Metrix plugin for Photoshop. Free from http://www.panix.com/~jnr . Correcting seams for whatever reason is vastly easier if the stitched panorama is delivered in a layered .PSD file, so that the images are still separately available. This is one of the big advantages of Panorama Tools. However, I note that the stitcher in the new Photoshop CS will be able to do this too.

Thanks for the link John. Good information.

Where do you look to develop panorama pictures with more than three pictures stitched together? My developer (Costco) can only do 3 pictures stitched together. Anything larger and their equipment won't do the job! Thanx.... Tom

i am using PixMaker Pro to do the sticthing and it works great. simple to use. Can go to their website: www.pixaround.com to find out more

Definitely try The Panorama Factory if you're looking at single row panos. I haven't found a better, easier program with results that can touch it.

Did you have costco do the stitching? I put 4 prints together at home and cropped the final at costco for a 12x36 print

Randolph,

Just so you know, you are responding to a 6 year old question. The memeber you are addressing was last active 3 years ago. I doubt s/he will answer you, so don't take it personal.

And
