Caires is a good friend living in Santos, 70km from Sao Paulo.
He shoots both film and digital. With medium format he shoots a Pentax 67.
And recently he bought a Linhoff Technik 4×5.
But most interestingly, he used an old Jobo lift to built his own rotary processor, much more elaborated than mine.
He made a short video showing a clever device he invented to invert the rotation of the drum.
