If you’ve avoided the common problems when shooting photos for a panorama, stitching should be easy. There are numerous panorama programs available, many of them free, and you probably received one with your camera.
Most programs operate in the same way, but experience has shown various strengths and weaknesses to many of them. For instance, some programs are better than others at creating a more uniform image, but will have trouble generating a flat horizon. Some programs have limitations on the various patterns they can stitch besides vertical and horizontal lines. But in the end, trusting the automatic programming should deliver good results most of the time.
What to do when the result isn’t good?
A good understanding of the stitching process helps. As stated before, most programs look for recognisable features arranged in a triangle on two pictures stitched together. Sometimes the software cannot find those features, but you can almost always manually select them.
The exact way to accomplish this will vary from program to program. When doing so, try to select features that:
- Offer good contrast with their surroundings
- Are, as much as possible, equally distant from the place the picture was taken
- Are in focus
- Are as distant from each other as possible, and do not form a line
After that, a little practice to better understand the particularities of each program should be all that’s needed!
