September 01, 2005
In the previous entry I gave a few rules for taking photographs for panoramas. Specifically:
- Use a manual exposure to ensure exposure is even across the whole set.
- Use a tripod to keep the point of view consistent and the horizon level.
This was taken on auto, and hand held. I obviously wasn't paying too much attention to keeping the camera level and look what autostitch has done to the waterline in an attempt to match everything up. You could water ski on that lake without a boat (reminds me of a joke about an Irish waterskier:-)
If you straighten up all the pieces first (some of them needed rotating by 3 degrees to get them level), then you get a much better result:
The waterline is much straighter now, but the exposure still varies a lot between segments. I could also manually tweak the exposure to match them all up before stitching them together to make it work even better.
(By the way, the ghostly child is the result of him moving between shots. I haven't got around to fixing that yet!!)
It is much better, though, to get it all right from the beginning. This one was taken with the camera on manual, and mounted on a tripod. The exposure is even across the whole panorama and the waterline is level. And no manual fiddling involved first:
The first one (in its two versions) was taken from Rowardennan Forest on the east shore of Loch Lomond, the second from Firkin Point on the west shore, both this last weekend. The mountain in the second one is Ben Lomond itself.
