When shooting photos for a joined up image the most important thing is to plan the shot before hand, by this I mean take the shots for the project, not get home and pick shots taken as individual picture. When taking the shots,
- Set the 2 edges in your mind
- lock the exposure and focus for the whole set of shots, if your on digital take a shot of the middle that’s correctly exposed and focused and lock at that.
- Over lap the shots, the more the merrier.
- Try to pan smoothly, keeping the camera level.
Once done you should be left with a set of shots that should nearly fit together with out any computer help, like these.
The next steps take place on Photoshop CS3, it will differ on other software, but not by too much.
