stitching question

oh wise and learned ones:bow

camera is a Kodax DX 6490. I set up the tripod. I had it level. I had it on "Auto".

(and yes, I need to learn how to adjust the contrast to match the frames)

the problem: the frames do not match exactly. so to get this one, I matched the top of the far mountains. you can see the mismatch in close.

the question. how do I get them to match next time? My guess is to set manually and have the same focus. or :doh use the "mountain" icon for "far" to keep the focus the same.

thanks

Good question. I can see what the problem is. A secondary problem is that by having it on Auto, the exposure is going to change as the scene changes and thus the light levels change. Interesting challenge.

Sorry I can't help, I've never tried panoramic stitching.:D.

Maybe you could try manually focusing on infinity. On a bright day, you'll have a small (high f-stop) aperature, so most of the shot will be in focus anyway.

And if you have the camera on Manual, you can set one exposure for the entire shot.

Here's what I would do...

First off, Brighten up image 2 a bit til it fits in about right. Do the same to image 4. I'm counting left to right here.

Don't worry about the sharp edges. You'll fix it next.

Now...you need to start using layer masks to blend. Follow the technique listed here. You will never -EVER- look at Photoshop the same way after reading and doing this. Then use the technique to soften the edges of the frames. This should make the blend more seamless.

If that doesn't work check this thread for software that can do it for ya...

thank you. I was guessing I had the focus off by using the "Auto".

Photoshop CS does it, as does Photoshop Elements. The job they do automatically is pretty darn good.

And when shooting you have to make sure that nothing changes from shot to shot. You can do this with manual mode, or you may be able to lock exposure/focus with your camera from shot to shot.

My Canon S1 has a "stitch" mode, and combined with the software it comes with it promises to stitch panoramas automatically. I've only used it once a few months ago, and came up with this:

Now obviously I didn't touch this other than to let the software run on auto, so it's crooked and could use some levels, etc. But this was 8 or 9 frames handheld.

The reason I bring this up is that until I read this thread, I never really thought about how much would go into making a panorama manually. Buddy, I think your first attempt is really good for being manual! And you've made me curious to see if I can make a good panorama next time I have a suitable view. Thanks for posting this thread and giving me something else to try!

For some reason, that link doesn't seem to be working for me, DJ. I tried cutting and pasting without any luck.

Let's try this...

Did this one work?
