For industrial photos, probably true. I was wondering about for
instance the mainline advertising industry. Think Photo District
News.

Not for professionals, but I understand slightly insane amateurs are
kludging up large format cameras. They are using scanners in place of
the film. So they have a large ( maybe 8.5 inch by 14 inch ) " film
". And can use tilts and such to get exactly what they want as a
photo.

The disadvantage is of course time. No stop action photos using a
scanner as film.

And then there are the astronomers who use software to stack up images
to increase light sensitivity without losing resolution.

I built an astronomical camera into an instrument that detected very
faint infrared from abnormal conditions using minutes-long exposures.
The software that came with it subtracted out a reference exposure
with the shutter closed to cancel out hot pixels. That application
didn't require gamma correction.
