| Jasper Lake Panorama |
At the left hand side, you can see some bighorn sheep, but most of them were on the road or at the other side of the road. On the other lakeshore, just right of the center, you can see a freight train. That was one thing I did not take into consideration when I started taking the photos. I was not aware of it before the train blew the horns, I was so focussed on taking photos.
I had to resize the picture significantly to 3109 * 512 pixels, it was way too large for uploading to ipernity.The stitched photo was made of 12 handheld portrait oriented shots (JPEGs), camera was set to manual exposure. File size is 16509 * 2719 px (44 Megapixels), compessed TIFF file is approx. 170 MB.
Stitching was done with Hugin, GIMP was used for resizing, no post processing.

I have been on a business trip this week, there was no access to the internet at my customer's site. My apologies for the late reply...
There are different ways to do it, probably the best way is to use a tripod and a special tripod head for panoramic shots. I even found a how-to to build your own panoramic head for 10$ on worth1000.com.
I usually do not carry a tripod around so my way is use freehand shots:
- look for a scene without too many foreground objects, moving objects etc. that avoids strange effects like ghost objects etc.
- set camera to Aperture priority mode and try to find out what the fastest shutter speed is (half-press shutter at different positions and look at the meter readings)
- set camera to manual exposure mode and enter the combination of shutter speed and aperture
- manual focus, no zooming between frames of course!
- no polarizer, otherwise you will end up with a very strange sky
- if you hold the camera in portrait orientation, you will end up with more vertical pixels, so the final panorama will be higher compared to landscape orientation, but you need more shots. As the horizon will not be at the same position in all frames,it is easier to crop if the frames are portrait oriented.
- I guess most people shoot from left to right., so do I. My experience is that it's better to point the body towards the right end of the scene. Then I rotate my body to the left and rotate right with every shot. This reduces the tension in your body instead of increasing it.
- I try to overlap the frames by 10 to 20 percent, that makes stitching easier
- I am using Hugin for stitching, it is quite easy to use (there is an assistant - load images - adjust frames - generate image) and the results look good to me. And it's free...
- I use GIMP for post processing
Carstenpro replies:
For this I overlap by more than 50% usually. So you do not only have shared points each following picture but to the next one and sometimes one after as well. With a digital cam number of images is almost no problem. For orientation I use the AF points of my cam. This way it's easy to keep the horizon (almost) straight without a special tripod head and to get an even distribution of pictures.
And one another thing: depending on the scene it might be sensible to fix the white balance setting. Else the colours might change over the pano...
Paprikaplains replies:
I haven't tried 50% overlay or even more, distortion is probably a good reason to give it a try.
I don't own a DSLR, so I use my EVF and turn on the grid, this usually helps a bit. In manual focus mode, the AF indicator becomes a circle and this is not helpful at all.
Manual white balance is a good point, although I did not have any issues with it before. You can also use RAW mode to get around white balance issues. I usally don't do it because it takes about 7 seconds to store the file, that's too much for a longer sequence of photos.
Carstenpro replies:
Actually pano's are almost the only occasion when I turn on RAW+JPEG, because I do not want to have to convert all the images necessarily. But I could... ;)
Annjin replies:
Very interesting to read how to do it ... and impressive work I must say! Now I'm even more impressed over your panorama, knowing the work behind it. Thanks again, enjoyed reading about the process a lot, perhaps I'll give it a try when the rain has stopped ;)
Paprikaplains replies:
Simply open the window, take some telephoto shots of the building at the other side of the street and start stitching...
And you can even do "vertical panoramas" :-)
Annjin replies:
though my neighbours might find me a bit strange hanging out of my window pointing a tele lens at their house, I'll give it a try... fun to try new things .. !!!
thanks again, I read Carsten's post too and I'm still learning new stuff :)

A photobook is probably a good idea, I just started selecting and editing some photos from Canada for this purpose.

out of 4 pics for you Dieter. I am not sure I can remember the whole path.
