#Photo image enhancement
On May 10, as everyone will remember, there was an annular eclipse of
the sun. The path of annularity went through Toronto where I live so
my wife and I took the day off in the hope of photographing this once
in a lifetime event.
To avoid eye damage, we tracked the progress with a pin-hole camera
and used a page behind the viewer to indicate when the camera was
properly aimed. I thought that exposure could be done using the
"auto" setting on her little Ricoh. In that lay the misfortune. The
pictures were over-exposed. The "ring of fire" became the circle of
fire. The sun on our slides looks like every day Sol!
However, there is SOME contrast there and I had an idea which prompts
me to post this message. Can one do the following?:
Digitize the picture to get an IFF image.
Use a paint program (or write a little C-utility) to fill in the centre of
what should have been the dark area pixel by pixel.
Prepare new slides of the result.
If the Amiga is ever used for such computer enhancement, this surely
would be a classic application. These pictures threatened never to be
taken at all as the sun flirted with cloud cover throughout the
eclipse period. In fact, a really dramatic picture could have
resulted: the "ring of fire" right next to a billowing thunderhead.
So you see my dilemma. Instead of a great picture, I have a lousy one
which might be rescueable. I am confident that I can perform the IFF
image enhancement stage. My question is two fold:
Does the equipment to go from analog slide to IFF and back exist and if so,
what is it called?
If such exists, is there such a commercial venture as a digitizing service
whom one could get to do the hardware part of this for a fee? One suspects that
such equipment would be too expensive to unless one is doing more that touching
up the occasional picture.?
Any ideas anyone can give would be much appreciated.
Cheers!
