Thanks. I was looking at that again and the close image really stands
on its own. I think the combined image might be too cluttered.
What I've managed to produce so far is too cluttered. The massed detail
of the trees overpowers the icicles.
That said, I'm still trying to figure out how to use this tool. The
images seem to be projected onto a sphere, then aligned, and then
projected back to a plane. That makes sense if the images are part of
a panorama but these images are mostly on top of each other and I had
to do a bunch of roll, yaw, and pitch of the resulting image and I
have no idea why.
First time, I tried using Hugin's align image stack function. That
failed with an error. I think the focus in the two images is so far
apart it can't find any control points between the two.
Second time, I loaded the images, went to the GL preview window, and ran
the Assistant. It gave me an image with the icicles very sharp and the
trees all blurry (because that's how they are in the close image), even
using the Exposure fused from stacks output.
Third time, I gave the far image a second lens, ran the various
alignment steps, and came up with - an image much like what I got the
second time.
The fourth time, I added a mask to the close image, drawing one to
include the biggest of the icicles. That produced an image with that
icicle sharp, and nothing else improved over the previous images. While
you could go through and mask everything you want included in each image
(icicles from close, trees from far)... that's a lot of work and I'm not
sure it would produce anything like what you want.
Fifth time, I removed the mask and set Hugin to output remapped images.
Then I fed them to enfuse using a command line based on what I found at
this URL:
https://macrocam.blogspot.com/2013/09/using-hugin-for-focus-stacking.html
That produced an image combining the focused trees with the focused
icicles. Well, the icicles are sort of focused. There's an odd,
ghost-like sort of look to them, like enfuse sort of fused the in-focus
icicles with their out of focus versions. But it's enough to reinforce
the likelihood that an image combining the two would be cluttered and
crowded.
So I think it /could/ be done, I don't think it should be done. The
close image looks to me like a much stronger image than the far image.
In the far image, the icicles just look like mistakes, that you were
trying to get a picture of the sun-lit trees, and the icicles are just
in the way.
I think this is one case where doing an actual painting combining the
two images could make it work, but even then it might look cluttered.
The focus stacking might work better if you have more focus layers than
just two. Perhaps images with the two dark stumps in the snow are in
focus? Well, maybe not. I see they are in focus in the far image, while
the trees themselves aren't as sharp.
Maybe you could try it with a pinhole could come up with enough depth of
field to get it all in focus?

That made it. It's been awhile since I did a focus stack, will see
how it goes.
That close image is LOVELY!
