Since some time I am experimenting with DRI/HDR techniques suitable for my landscape purposes.
Hereby I want to show my first positive result ...
- the aim is to find a technique which relults are moreless eaqual to using a ND-grad for landscape photography.
The problem I have with my Lee ND-grad filter system is, that it is unhandy, needs space, need several filters to carry and take care of them, doesn't fit (perfectly) on all lenses.
The bigger problem is, that I cannot use it for panorama stiching.
- problems with DRI/HDR software processing I had so far:
one needs a tripod, very time-consuming when combined with panorama stiching, ugly halos, unnatural tone mapping
The technique of the following shot is:
- the photograph is stiched together from ~25 (landscape format) frames
- each row of photographs has a different shutter speed
- up row is 1/360 @f5.6, down row is 1/80 @f5.6 (inbetween 1/250, 1/125, 1/100)
- that's it, everything else (perfect blending the layers) handles the stiching software
advantages of this technique:
- no tripod needed
- no ND-grad filter system needed
- no HDR/DRI software needed
- amazing IQ through panorama stiching
- natural looking results
Cheers
Tobias

Thanks excellent Tobias - but still I did not totally get it how you made it...
How come one does not see horizontal stripes then?

It's because the stiching software does a perfect job blending the
rows of frames with each other.
it's called: blending option "smartblend"
The key is to do much overlapping inbetween the rows (vertically), horizontally a normal pono-shooting-overlapping is ok.
The shot was rendered in 2 min., ...

Do you use Photoshop for stitching or a stand-alone stitching software? I've used Photoshop a LOT with some good (and some decided NOT good) results, but have not yet tried others.
your idea to use different shutter speeds is one I've never tried. Have you tried using different apertures in stitched photos?

I tried it, but there's actually no use doing it.
What is really like is to shoot (let's call it) Multi-Focus-Panoramas.
#9 from this series is one of it:
(I shot with f5.6, because of lack of light, but it looks like done on f16)

I think it's time to write the "advanced guide for panorama stiching" to summarize the techniques which I found out and use ...
