I've got this wierd urge to do it in colour. For me the very idea of using colour film is wierd -) I just checked the cheap 4x5 colour film is a chunk. Worse I'm not sure I trust this new supplier. His prices seem good but then the website he tells me is right up to date show Agfa APX 25 film. Doing this in 120 would be cheaper. B&W 4x5 film is a fraction of the cost of 4x5 colour.
