Thread: Comparison of cost?

  1. #1

    Default Comparison of cost?

    Which would be cheaper?
    1>using 800 pushed to 2400 and then developed by push processing?
    2>buying 2400 flim straight.
    Using colour negs in both case.

    think the cost is ard $3.50 for pushing each stop

    not sure what's the price of a 2400 film or if there is one

    never seen 2400 film...
    maybe you are confused...

    one stop mean multiplying by 2...
    800 x 2 = 1600....one stop
    1600 x 2 = 3200 one stop...

    therefore 800 to 3200 is pushing 2 stops

    maybe you multiplied 800 x 3 = 2400? push 3 stops? thats incorrect.

    based on this rule, how did you process your 800-2400 push? because the lab does not push inbetween stops.... either 1 or 2.

    Never heard of 2400 film before. Anyhow, think it really depends on the lab which you got to for develping. How much do they charge for push processing?

    Well, I've got certain amount of success underexposing Press 800 film by one stop. The lab corrected the unexposure pretty well for me.

    The cheapest of all options would be to just set your ISO to 3200 (thereby underexposing your whole roll by 2 stops) and then ask the (pro) lab to process normally (i.e. at ISO 800), but take special care in correcting the underexposure.

    Most negatives have pretty wide latitudes of +/- 1-2 stops and should be able to handle the underexposure pretty well.

    If you want a sample try seeing this. Underexposured by 1 stop (set to EI 1600 with ISO 800 film). But the compression is pretty bad so the graininess cannot be judged accurately.
