Yet another mistake!
I loaded the 4x5 b+w sheet film incorrectly -- the wrong way round ie., back to front! This is something that I have never done before. I cannot explain how made this mistake.
I do have an image after processing the film in Rodinal, but the image quality is poor. There is little detail in the blacks. To my suprise there was vignetting in both the upper corners, despite using a recessed lens board and a wide angle bellows.
The particular subject is the railway yard at Quorn in South Australia. It is early cloudless morning during the winter months. The camera a 5x4 Sinar F1 monorail, the lens was a Schneider-Kreuznach 75mm f.5.6 Super Angulon, and the sheet film was Ilford FP4 Plus. Though the camera is a monorail it is light enough for field use, which is how I use it.
