Speaking about books, a few time ago I decided to develope my films (B&W and chrome only; no color negative). So I bought the book “Formulario Fotografico” by Reinhard Viebig that brings most known formulas for film development. I got it used and cost me 5 US dollars (shipping included). Back cover is all white.
“Cameras Classicas” by Mario Bock gives technical and historical details of some classic cameras. As far as I know it is the only book in portuguese language about this subject.
But I think he wouldn´t mind if I post a few more pictures I downloaded from his flickr.
Leica M4-P, M3, III and M8 along with more photo books.
I love this picture: The Three Amigos (Rolleiflex 2.8F with Planar 80 mm f/2.8; Wide Rolleiflex with Distagon 55 mm f/4; Tele Rollei with Sonnar 135 mm f/4). Not to mention some Rollei photos behind the cameras.
More info regarding Tele and Wide Rolleiflex here.
And below, more of his Rolleiflex colection. Top shelf: Rolleicord, Rolleiflex 2.8E, 2.8C, 2.8D and another 2.8C. Bottom shelf: Rolleiflex 3.5F with Tele Mutar 1.5x, 3.5E, 3.5D and 3.5A with a very strange focus knob.
More info about all Rollei models here.
