I love to photograph panoramics (pans). I have included a recent image on my homepage, which was from a road trip around California - La Selva Beach, Santa Cruz. It gives such a great depth and printed big you can really get to see all the details in the picture. I shot on my Canon 1ds Mark III using the 17-40mm f4 L Canon lens - i like how the wide angle format gives this elongated sense to the photograph.
When I am commissioned for interior work, I like to try and incorporate a pan into the shot list, or if something jumps out at me i shoot it! Like when i photographed the interior of a new music studio in New York BEAT 360 I managed to shoot this:

To get technical - i shoot various fames on a tripod, overlapping about 1/3 of each images with the previous. this allows greater flexibly with the stiching together at post production. I also bracket each exposure 1 stop either side so I have the availability to composite elements into the final image. For example the outside of the windows was shot at a darker exposure and then introduced to the final.
POST PRODUCTION: I retouch most of my own work, to give me lots of creative control - using the obligatory Adobe Photoshop CS4 I use the the command File> Automate> Photomerge to merge the exported .psd files together. This gives a really great effect.
