Light source


this may interest some of you.

While testing for exposure time with a friend, we realise that something was
let say bizarre and we decided to test our light source. We exposed for 1/10
our standard exposure time to obtain  a mid to light gray. We made the test
print the same size as our usual prints using no transparent materal.

As soon as we could see the result, (carbon print) we where stunned, there
where major differences in tone all over the print and all sort of
undesirable artefacts.

We where using a point source and decided to try an UV tube bed instead and
of course we will make another test just in case.

The lesson learn from our experience may be useful to others and I thought
we should share it with you.
