Hi.

I was uploading six panoramic images that are all stitched together from many frames, 5-50 frames(see details with each image). All taken in March 2006.

1) 2) 3)

4) 5) 6)

Can you pick out the one you like and the one you don't like?
Comments are appreciated.
You can click on the thumbnails to see them at 640 pix in my dpc portfolio and also see the images larger here.
Best viewed on a monitor in a dark room.. ;-)

Thanks,
Amason

WoW!!! These are amazing!

I Love number 4! Great shots!
 04/21/2006 07:00:46 PM · #3
I'd love to see #4 in a bigger size, it looks VERY promising, indeed!!!!
 04/21/2006 07:01:07 PM · #4
By *far* #4 (Norðurljós) is my fave. An outstanding pano. I assume the light on the mountain peaks is from a setting moon?

#3 is my least-liked among the group.

#4 is by far the best to my eyes. They all are competent work, but for me only #4 actually sings, and it sings very brightly indeed.

#1 is my favorite, then #4. these are rad.

I really number 4 also, but I think 6 is my favorite. These are beautiful!
 04/22/2006 03:54:50 AM · #8
They are all great. I like best nr 1 and least-liked nr 3
 04/22/2006 06:09:02 AM · #9
Wow! Great shots! I like 'em all, in this order of preference: 4, 1, 3, 2, 6, 5.

I really like your images. I'm very interested in hearing more detail about your experiences stitching panoramas, especially #1 since I did something similar with a 30 image three horizontal row one recently and it was a lot of work using CS2. Much of the work was fixing contrast and color blending.

Autopan Pro does a super job with blending compared to CS2.

In my experiment Autopano Pro (trial version 1.2 beta) had these main issues:
1-Distortion
2-Bluring of merged sections from some of the merged images
3-Less major merge issues resulting in ghosting and mismatches

How do you reduce image distortion? It is my biggest problem with Autopano Pro and I can't figure out how to deal with it though have no problem at all in CS2. How do you prevent or reduce blurry sections of the merge image? Both these are almost impossible to correct after the merge. I presume that you correct remaining mismatches manually with the healing tool or cloning.

#4: Magic Moment is just glorious! Great work on all, but I really love the ethereal feel of this one. Just gorgeous!

These are unbelievable. #4 is also my favorite. Well done.
 04/22/2006 12:21:03 PM · #13
number 4 is deff the best.

Yes, I use cloning, healing brush etc. I haven't noticed a problem with blurry sections, when I shoot the images I try to overlap pretty much, especially when using wide lens. On 17mm I overlap around 2/3, using only 1/3 to the sides and if I'm taking it in 2-3 rows on 17mm, then I overlap vertically about 2/3 also the final is maybe 1 and 2/3rd of a frame. When using normal lens or the 60mm that I used in some of the images I overlap around 1/3rd. There must be enough detail in the stitching area on every two frames side by side for the stitching. I have also stitched many photos in 2-3 parts when I got in trouble.

For those who don't know it.. Same settings should be used for all of the shots that are ment to stitch together for one image, same white balance (can be changed afterwards when using raw format), same focus setting (manual focus and do not zoom between frames), same aperture, same iso and same shutter speed. That means that all of the frames should be taken at exactly same settings. If you use raw you have to convert all of the images with exact same settings, not auto!
And... you should avoid using polarizing filter! Also when taking many frames outdoors for stitching later, be very quick when changing views between frames, that is very important because the light often changes.
I had that problem when taking the 50 frames with image #1, there was a moonlight and clouds were sometimes going infront of the moon so the light changed a lot, I tried to wait and take some frames again but in the end I had one part of the stitched image brighter than the rest, I used the tools in Photoshop trying to fix that.

I haven't been using Autopano Pro very long, but I really like it so far...

Sounds like you and I have done some of the same things to images for fixing. I've also cropped sections from original frames and pasted them into the panorama over hard to fix merge defects and that works very well too. At the sizes we've displayed them on the web most defects don't show up, but they have to be right for prints.

I overlap my images by about 1/3rd which is what CS2 documentation suggests. As far as merge mismatching is concerned both have about the same amount but they come out in different ways.

I've tried out Hugin, PTGiu, Autostitch and now AutoPano Pro as well. Of those I like Autopano Pro best so far. It is easier to use than the others and I've gotten it closer to the right perspective. But I'd chose CS2 over any of them if the contrast and color blending worked better.

You should check out PTAssembler with Enblend and Autopano as a plugin working together. That is probably one of the better methods for panorama stitching.

Autopano Pro is great for its simplicity as a standalone program but not as good alone as the other working together.

I've also heard that Autopano Pro and PTAssembler work well together, I haven't dug into how or why... PTAssembler used first, then rendered with Autopano Pro.

Some people wanted to see the images larger, maybe they didn't see the link. For those who wanted to see them larger, here are #1 and #4 at 1000 pixels wide (as also linked to):

#1


#4

I'm gonna have to get up a little extra gumption to try that. I did find a web reference how those three things are supposed to work together. I just don't want to put a lot of effort into another method where I get a distorted output for less than 120 degree panoramas. I don't mind extra work if I can get undistorted results. I don't know how to do that.
