Afternoon and Welcome to the Forum!
The K50 is a perfect camera to take panoramas with. There are not really any special modes or hacks necessary, although some approaches will work better than others.
Basically 2 steps:
- Take the pictures - You can go, right now and take two pictures with about 25% overlap - to start the process off.
- Stitch the pictures - Then take the images (jpgs or raw converted to tiff), down load Microsoft ICE, drag the images into ICE and it will stitch them together and provide you with the result.
Some techniques will help create a better results than others. Some techniques that may help....
- The focus, white balance, aperture and exposure should be constant from frame to frame. This will help maintain a consistent look and not make it appear that two images were stitched together. Now, I have shot a lot of panos in fully automatic (maintained focus) and the stitching program blended them very well.
- You should try to keep the camera level as you shoot the individual frames, otherwise they are walking either up hill or down hiill and you will loose a lot of the scene to cropping the result into a rectangle. Tripods help a lot, but you can shoot handheld. On the topic of tripods, some heads work better than others. For now, I'll just leave it at that.
- When you take a series of frames to be stitched together, you should rotate reasonably carefully around a "nodal" point. There is tons of websites and videos on the topic. You need to get the basics down first, make a few mistakes so that you can better understand the whole process.
- You can shoot horizontal and vertical panos, or a combination - something like a 3 x 3.
- You can shoot a pano with really any lens, wide angle, normal, telephoto, fisheye - whatever.
That is somewhat of a broad brush overview. Lots of material on all of this on the web.
Panoguy will be along shortly.....
