Sometimes you just can't get all you want into one frame. Like the photo above. You could buy a new lens that is even more wide angle but that is expensive and will also drag down the quality of the photo since wide angle lenses are not the best performer. But there is a way that will help you in a lot of situations. Taking several images and then stitch them together. The image above is 4 photos stitch with the software PTGui.
This is a great software specifically made for panoramas and stitching, much better than Photoshop. It is easy to use and helps you blend images together and compensate for exposure differences. But I do really recommend using manual exposure on your camera, no autofocus and stay on the same iso. This helps a lot in post process and will make for a better picture in the end. I won't go into the technique much more since there are endless guides on internet. But there are some pros and cons you might want to think about using this technique. Some you might not think about at first. The Pros are not many but can sometime be important.
- Lightweight, you don't have to carry around an extra wide angle lens
- You often get better quality photo using a normal lens instead of wide angle
- You can stitch together huge images and get several 100 Mega pixel at the end
- If you downsize the photo afterwards you still got better sharpness than normal
- The software will be able to handle small movements as clouds moving
- You can't shoot moving subjects if they cover more than one frame
- Not good for sports
- Harder to compose, since you don't see the finished image in camera
- You must have a reference point in photos, just blue sky and the software will not understand how to put it together
- The files can end up being huge, 2, 4 or 10 GB depending on how many photos you stitch together
- Dusk and dawn you have to be fast since the light changes fast
- You can do it without tripod but it is much easier with one
- Requires a quite powerful computer to edit
- Sensor dust will be repeated all over the image
- You have to check all stitching edges so that they are aligned
- Requires more post processing
- Final file will not be raw
But in the end it is a good technique when you need more field of view than your lenses can do. There is one last thing you might want to consider to. Make sure to keep the raw files. If you want to enter a competition they might want you to send in the raw files to to make sure it is not photoshopped. But try it it's a lot of fun.
