I'm interested in nitrogen burst agitation, and what advantages there are to this form of development if any for B&W 4x5 film development. I am considering this form of development due to the need to develop high quanities of film, somewhere between 25 to 100 sheets per darkroom session. My questions involve whether nitrogen systems maintain constant flow or intermittent per a normal inversion schedule? I have the capabilites to construct such a system but require input as to nitrogen header and outlet sizes, rate of flow, and timing if necessary. I also have a question as to film spacing. Developer replenishment will be manual at first, but I can develop a semi automatic system.(posted 8524 days ago)If the above is impractical, would a simple liquid pump system suffice? My idea is for a table top system using stainless clip hangers. I am not interested in Jobo, tube or tray development. Any practical ideas or paths for research are appreciated.
