Anyone know what software to use in order to stitch images shot at 10mm. There is a couple of packages out there, some use fisheye stitching software others use "normal" software. I am shooting using a pano head but am still getting wierd results using Serif PanoramaPlus 2. It works well with other lenses but not the Canon 10-22mm

Hope someone can help

You can fix the distortion using PTLens then join them.

If you're using shots taken at the 10mm end, they might have too much perspective distortion in them to be stitched together properly without any preparation ( like sorting it out first as mentioned above )

I have stitched lots of stuff together, but haven't tried using 'ultra' wide shots because I never thought it'd work...

Thanks Mad-dogs.
Nik I have seen images created with fisheye lenses stitched together.

Thanks

Panorama Factory does it all for you, including fixing the lens distortion.

Very few stitchers don't...but if you sort them before stitching, you have to remember to build a lot of overlap into the series.

I tend to do that anyway Keith, regardless of focal length.

Oh well, you live and learn...

Seems a bit of a waste of a wide angle / fish eye though, if you are going to get rid of the distortion to stitch them together and get a wide shot..may as well take a load of 'normal' shots and stitch them hadn't you ?

I quite like the 10mm distortion....

I agree Nik and haven't used my 10-20 for stitched shots, but each to their own. Smile

Hello

The point of the fisheye or wide angle is to take less shots for the panorama so that it can be viewed with flash or within a java aptlet. Instead of taking several shots you can take less to create a spherical panorama. Or in the case of a 10-22mm almost spherical. There are spherical images used by property companies who shoot 4 images for a full spherical image. the sigma 8mm fisheyes has a 180 degree view so only 4 images are needed to stitch the entire 360 degree image together.

Stephan, I can't recommend a fisheye for 360 panos. I do virtual tours for a living and one of the selling points of the tours my company does is that we use a specialist pano lens. Using a fisheye causes distortion in the results (lines which are supposed to be straight always look curved) and can also exposure banding, meaning the joins are visible. The only ways to get rid of the distortion are to allow plenty of overlap or sort it out in software, either way means losing part of the image and therefore taking more images in the first place.

Viewing the image using flash or java is nothing to do with how many images go into it, but how big you make the final image. Even then (within reason) the size doesn't effect viewing ability, only download time.

If you are on Mac platform there's Defish - Dr Karl Harrison at www.chem.ox.ac.uk/oxfordtour/tutorial/index.asp uses fisheye lenses to great effect.
