developer to move those data around. The easy fluidity of data is
A parent of one of my students sent me the following question:
At Lower School graduation, I took a great photo of a friend of mine
and his son. But it's somewhat out of focus. I want to print it,
but in focus. My intuition tells me that all the various light
rays hit the film -- but not quite in the right place.
So it seems to me that all the data for a good
print must be there on the emulsion. And if I could only bend the
light rays in the printing process (whether before or after it goes
through the negative, I'm not sure), it should be possible to
correct the error and make
the print come out in focus. (After all, they fixed the Hubble

My first thought is that you are seeking an analog solution to a
You're probably right that all the necessary data is there, just
not in the right place. And your photography friends may also be
right that there are no photographic techniques available at the
a digital reality, not an
analog one or we would have had it sooner, I imagine.
Is anyone on this list a knowledgeable photographer who can resolve
this question one way or the other. I'm not sufficiently aware of
the optics of the development process to answer directly.
Is there an optical solution to the focus problem?
Thanks for any help you can give.
