Re: Panorama Trials and Tribulations (warning very wide images)

So my simple pano was just 6 shots. These 6 in fact. The overlap was only about 25% so I had nothing to discard and had to use the middle 50% of each shot. Images 2 and 3 clearly show how turning the camera has affected the percieved angle of the roads and the last 2 show the same effect with the wall even though the overlap was a bit more generous.

Re: Panorama Trials and Tribulations (warning very wide images)

I like to create the web based panos such as
http://www.w9259.co.uk/Arches%20NP%2...arches1_1.html

select the web link and then use the icons to navigate around and zoom in the image.

I use the crudest of techniques - lots of images merged in Photoshop or Lightroom and then processed in Pano2VR.

Re: Panorama Trials and Tribulations (warning very wide images)

I do a lot of panoramas and have done for many years (1981 with an OM-1!).
I have a set of tick-offs.
I usually use a tripod and get it set up as level as possible.
Try not to use wide angle focal lengths, 17mm in MFT at most , preferably the long side of 25mm.
Always use portrait format (gives you more foreground to work with). Aperture priority, focus point somewhere about 10-20m into picture (post processing will crop out the really close stuff).
WB usually takes care of itself.
30% minimum overlap.
Swing through the whole view to check what you want or not, this also tells you where you are going if hand holding (and if handholding 'unwind' yourself).
I haven't bothered with nodal points for years and have never had a problem.
Try for a finished image no more than 8 to 1 otherwise its too long.
In post processing if the option of cylindrical or spherical format is offered I usually take cylindrical as this reduces distortion.
If you want a real challenge try a vertical panorama. I have probably done less than 10.
If I find out how to upload images I'll stick a couple on.

Duncan, thanks for the tips. When I took these shots I hadn't given much thought as to how to maximise their effectiveness and just assumed the Olypus software would do exactly what I wanted.

Nice panoramas Alf.

Perhaps I was being a bit ambitious with a 6 shot pano and 25% overlap but I rarely do panoramas and have yet to learn its limitations.

Re: Panorama Trials and Tribulations (warning very wide images)

I have copied with permission the photos by OM USER and did a stitch using Affinity Photo.

With this, I did a pincushion correction. ie, I push the center bulge back. I did not correct the slant and by the time I cropped the wave off and the slant, there wasn't much left.



Same photo same stitching but this time, I corrected the waves individually. then I rotated the image clockwise just a few degrees, then using the wrap function, I stretch the photo slightly at the 2 ends..

These look very good with regards to matching the tones, white balance, and brightness. Much better than I managed manually. The centre looks very good in #1. I like the 2nd one better overall (really this is down to that path out of the car park looking a bit straighter) although I notice a slight blip where the roads in the forground bend a bit sharpish. I streched the ends on mine a little as well, just to bring the people back into the usual shape.

It was only a 5 min job. I am still learning what I can do with the software and your photos cam in handy.

now that you mentioned it, I think it's caused by the straightening.
