I'd like to invite you all to my exhibition! It'll be starting on Friday 13th March and it's in... Beijing... So I guess not many of you will be coming along then :E If you do happen to be around Beijing then give me a shout and I'll send you directions!
What may still be of interest to you guys though is the panoramic shot. I took a shot of Harbin in winter which will run the entire length of the gallery - we were going for 7 meters but there was something on the way in the wall, so we had to settle for 4.6m. Even though I have a monster-resolution a900 this is something that you can all do - the point of panoramic stitching is that you make up for the lack of resolution by combining lots and lots of shots together. Here's what it looks like:
and the other shots in the exhibition.
Pano stitching is really easy. To start off with you need to lock EVERYTHING. Start off by locking your zoom setting - changing focal lengths throughout the sequence is going to screw things up. Lock your exposure (shutter speed, aperture, ISO) and if you're shooting JPG lock your white balance - in RAW you can set this afterwards. Finally lock your angles on your tripod - when you pan your tripod you want to make sure that you don't pan across and up, or up and to the side. Move the tripod in one axis only.
Set your focal length to encompass a much wider view than you want to end up with - what you'll find is that you get 'black corners' - areas where the camera misses the scene. If you're not careful you'll be using the clone tool to re-create a lot of these.
Finally, go home and stitch it all together using some software. I used to be a huge fan of Serif's Panoplus3, but unfortunately it won't output larger than a (frankly pathetic) 10,000 pixels. PS4 won't merge images correctly and is a bit fiddly - no preview for your panorama stitch type. So I've settled for PTGUI.
Give it a crack peeps - it's dead easy and you'll even get some good results hand-held.
