    I'm currently trying to experiment with stitching photos together, to form a wider view (obviously haha). I was wondering whether people would mind posting examples of their own stitching efforts?

    Here's a few more that I've done over the last year....

    Fairoaks Airport - Surrey
    [​IMG]
    Larger image here (427kb). The full image is made up of 6 images, and is around 25,000 pixels wide at 300dpi, so was a bit large for here! There are still some joins visible, and I have used quite a high level of compression to get the file size down, which has affected the quality somewhat.

    Holmbury Hill - Surrey
    [​IMG]
    Larger image here (480kb). The image covers over 270 degrees (north round to west) and is taken from an old iron age fort in the Surrey Hills. I forget how many images it was made from, but it was around 9 or 10.

    Pitch Hill - Surrey
    [​IMG]
    Larger image here (212kb). Pitch Hill is the next hill across from Holmbury Hill above. Apologies for the still 'obvious' join to the left hand side of this image.

    Friday Street - Surrey
    [​IMG]
    Larger image here (300kb).

    Larger image here (231kb).

    Friday street is a small hamlet set in the Surrey Hills to the west of Dorking, with a rather nice pub, The Stephan Langton, if you happen to round that way. The images are made up of 3 and 4 photos respectively.

    I recently became interested in stitching... I still have much to learn! It's fun to experiment - I've been using a free software progrm called hugin to stitch the images and then Photoshop to tweak them. I haven't had a chance to Photoshop this one yet, but what the heck - it'll do for now. ;) It's easy to see the places that the stitching sotware misses that you have to tweak, but it's most likely operator error. After Photoshop it's difficult to see the joints. I would have liked to do vertical shots to get more of the city line, but I didn't have the right tripod with me that trip.

    This image is made from 5 images of Dundas Square in downtown Toronto on a rainy and foggy day last week... Exposures were 1 sec at 200 ISO on a D50.

    I'm not to bad with my photoshop skills, but I havn't mastered the art of stitching.
    When you take the photograps in a series... Do you pan? OR use a tripod and rotate slightly for each shot?

    Tripod. If you pan...you will only get a blurry image.

    There are special 'panoramic' cameras that do actually pan as they record the image...but I think that the lens has to pan while the film is stationary...which isn't possible with a regular camera.

    Also, here is a good tip for stitching. Use your camera in portrait orientation (vertical)...and over lap your shots by 1/2 or 1/3. There is more barrel distortion at the ends of the frame (top and bottom in portrait)...it's easier to stitch the long edges together.

    Cool, cheers I'll test it out.
    I guess using an ultra wide angle lens doesn't help. Seems to distort the edges a bit more than usual.

    Using a short focal length causes a lot of distortion, and some stitching programs that read exif data will not even attempt to merge photos that have short focal lengths.

    Using a tripod makes for better results, but if you do make sure it is level in all planes.

    Just been looking for a Panoramic photo tutorial and came across this thread.

    This is the best I could get from Photoshop so far.

    Just Google "Panoguide" The best site I've found to help. You will need the proper head on your tripod to do it correctly.
