Hugin HDR/exposure fusion Techniques

[Anthony G]

Is there an up-to-date tutorial for exposure fusion with Hugin?

In particular methods of control point generation and alignment. All the online tutorials are from 2010 or earlier.

Currently I'm stacking my 3 exposures (-2, 0 +2) and then using the "CPFind (multirow/stack) setting to align all images at once. I'm not sure if there is a better way to do this, but I find the control point generation stage is taking long.

Why, do you expect things to dramatically change since 2010? :)

Don't know a newer tutorial. I prefer to do all the exposure fusion or HDR before stitching them in Hugin. Doing like this you can choose among more tools available, like linux command line tools, Luminance HDR, FDR Tools, PS, enfuse, Photomatix, ...

To align (not necessary if you have used a tripod) you can use align_image_stack, that comes with hugin and is also used by Luminance.

Bests,

I guess I was just trying to keep my workflow as simple as possible. I've got about 20 panoramas to stitch (19 stacks each), and didn't want to spend much time tweaking.

At least in principle, it should be better to fuse after stitching, so that enfuse can follow edges
over boundaries.

In practice, since this take much more RAM, I always do what you do, and fuse before stitching - I shoot using a tripod, so
fusing stacks is easy.
