A great amount of patience? Running it under FluxBox, which consumes

I made mine from a series of frames I shot covering our trip into the
harbor at Victoria, Canada, (on a ferry). They covered 3-5 miles of
shoreline.
This doesn't really sound like a focus stack to me. Are we talking
about the same thing? I'm not talking about exposure blending with
enblend, but focus stacking with enfuse. I think focus stacks may need
more memory, because they have to look at the neighbourhood of all
pixels to determine the local contrast, which is used as a weighting
criterion. I know that I could have gone 8-bit but chose not to. And
of course I could have chopped the thing up into several smaller
partial images - there's always a way. Currently, it takes a lot of
finessing to do stuff like that, and that's one reason why I'm
developing the scripting interface. When I did the image I was talking
about, it didn't rerally take long, but it took massive amounts of
memory, and when I used larger source images, enfuse simply failed
with a bad alloc. I have an idea what I could have done on top of what
I did to manage with consuming less memory - alas, right now I can't
try it out because the AC adapter of my laptop gave up yesterday...
No, definitely not a focus stack. I'm sure doing things with focus
stacks would use much more memory. I was just talking about producing a
750MB panorama.
I've done a couple of HDR images, I don't know if they consume memory at
the rate of a focus stack.
Question: were you running the enfuse stage from command line? I don't
remember if you said so. I had to do that once before I doubled the
memory in the laptop.
