Sorry to dig up an old thread...I am learning how to do nice pano shots but have failed...Basically I get pictures that look like fisheye pic and need details on how to eliminate these distortions.
I am using Canon's 18-200mm, if I rem correctly I am using the 18mm focal length. So I am wondering if the problem lies partly with the lens and how can I reduce such problems if I want to use at 18mm.
Thank you guys so much. I have a 3 way head btw.
Hi,
Your pictures are curving because of a number of reasons:
- you've probably taken too many pictures (start with 3 or 4)
- You're shooting end to end or 180 degrees of semi-circular pano shooting which will always produce a curve
- strange angles occur because you're probably not in the middle of your pano shoot and the layout you use to stitch your panos may not have been right (play around with auto, perspective, cylindrical, spherical, collage, reposition in Photoshop or a stitching program)
- you will always experience distortion with whatever lens that you use if you don't do any lens correction in Photoshop (for most of your pictures you'll probably need to adjust the geometric distortion)
I've done a lot of panos but I'm a bit different because I don't normally use a tripod:
Here's an example of a curving scene that I didn't correct mainly because I used the wrong method (shot too many and end-to-end) and it wasn't the right place for a pano (sloping hills) :
I think I got lucky with these shots because:
- I tried not to shoot too many for stitching
- Stood really still and held the camera steadily while shooting in a smooth and consistent manner
- Overlap each picture, some say 20% others say 1/3, it doesn't matter just overlap a little bit for each shot just not too much
- Always shoot in portrait view not landscape
I agree that if you have a tripod and a pano head then you will have a more consistent result (ie. flatter). I only just bought a tripod and have used it sparingly for my last trip, not sure if it's worth carrying the thing because of its weight and bulk so I will probably still rely on my old habits for pano shooting unless I'm shooting at night.
