Hi Tappers,

This is related, honest!

Wanna have some fun?

For your pinhole cameras lab make up some negative prints of famous persons
which your students may not recognize in the negative. Madonna, Dr. Death
(Kevorkian), M. Monroe, S. Spielberg, for example.

Then after they photograph these with their pinhole cameras they will get
negatives of the negatives and will sometimes recognize the famous persons.

Hi Paul,

Do you have the separate files for the Marilyn and Al images? If so,
would you mind sharing?

Do you have a Photoshop recipe that we can use to create our own? You
know, like maybe morph me into Tom Cruise or some other dude that chicks
dig???

Thanks,

Sam

Hi Urs


Have you seen the image of Albert Einstein that turns into Marilyn
Monroe when viewed at a distance?

One image is done with fine sharp lines the other is drawn with wider
fuzzier lines, at a distance the fine lines lose due to the loss of
resolution and the fuzzy ones take over.?

Check out this workshop I taught a few weeks ago:
