I made today this pano from a large scene and waterfall. Somehow it is not possible to distinguish scale and distances in the outcome. It looks like a simple 20mm shot. Actually it is stiched from 22 20mm shots Wink
very unsatisfying Smile ... the color version is even worse.







Cheers
Tobias

Perhaps it would give a larger impression if it was stitched in a different projection? Question

for this angle of view, spherical or mercator projection was the only possibility.

I'm not sure what that means but is that why the water seems to be falling at a weird angle?

Looks like the wind is blowing it?

What software are you using? You should be able to select a few others, at the very least equirectangular and rectilinear should never be removed as options...

I would be tempted to try rectilinear, and experiment with different center points and different view angles. You probably won't fit the entire image in, and there will be noticeable perspective stretching in the image, but it is somewhat more natural for a fixed view of a large scene. So it might not do your quality captures justice, but it might give a better sense of the enormity of the view. Wink

@Scheimpflug

Other projection methods don't give natural results at all.
The angle of shooting was too weird ...

True, those projections don't look natural as-is, but try changing the center point and try changing (reducing) the field of view. With the center point where it is, it optimizes the view for the rock cliff on the opposite side, which isn't quite as interesting as the top or especially the bottom of the scene. Wink

The small size of forum or internet viewing is also a hindrance to the perception of scale, as in reality this is a view which would fully fill your peripheral vision. The perspective looks funny when you view the full image, in ANY projection, because unless you print at poster sizes, it is hard to put your eyepoint in the right spot... it's like looking through a peephole viewer on a door, but from a meter away from the door. Our brains just can't figure out what's going on. Wink

So one potential solution to this, to capture the feeling of the location, is to center the view on an area of interest, set the projection to rectilinear to preserve straight lines, and then crop the field of view to a level which gives sufficient detail in your center point (the area of interest). This should then be viewed as large as possible, with the image centered... ie, the view is *not* designed to be zoomed into and scrolled around. Wink


If your stitching software can output an equirectangular image, I could remap it for you to show what I mean. I would just need to know the horizontal and vertical field of view of the rendering in degrees. I might also be able to find an example in one of my panos if it would help.


Also, my apologies if this is more C&C than you wanted... Embarassed It is certainly a beautiful scene, and you did a great job capturing it. Cool

many thanks for your ideas and help !
indeed, the crop which I did was not really "to the point".

Not at all, I appreciate and you make me think a lot Wink
