greenspun.com : LUSENET : Large format photography : One Thread

Hi all gentlements,

I usually shoot 2 identical exposure for backup pupose, but when the first one process fine, if I throw away the backup, will I need it in the future? To keep it, a very well library kind of system is need to organize them. I just don't know how to treat these backup exposure, if u have the same experience, can u give me some suggestion?

Thank you so much. Chin.

Keep the second good exposure as insurance in the event the first is damaged while making a print or scan.

My method of organization is to simply keep them adjacent in my slide library. They have consecutive transparency numbers, and the same caption in my data base.

Are you shooting transparencies or black & white? I usually shoot 2 identical sheets of B&W so that if after processing the first, I discover that I need to increase or reduce contrast, I can subject the second sheet to a different development and make a more printable negative. If the the first develops to my satisfaction (which is the case most of the time), I simply develop sheet #2 the same way and keep it as an extra in a separate file that I store elswhere in my facility. This way, if the unexpected happens, there's a chance I may still own a negative that's useable!

Thank you for all your response.

Robert, I shoot transperancy. To save money, I havn't develop the 2nd exposure if the 1st one is fine. Looks like 2 out of 2 people (100%) will develop both, may be I should consider that too.

Keep them both...you never know what's going to happen to them down the road....if you have 2 good exposures, commit one to your "deep/ long term file" and use the other for all your prints, dupes etc. The filed version becomes the "master", the other becomes the "surrogate"...this is the cornerstone for the type of system you'd use in an archive.....same with b/w....every time you actually USE a CT or a neg, a little teeny bit of it's life decreases.....this system is also good because with sheet film, there's always a chance of a stary hair or dust speck....alot of times that extra sheet will be a life- saver...FWIW, this is basically how we shoot & file. 90% of the time, we'll run both sheets (but we do it in-house) because we do alot of patron services in the form of printed materials....everything is sent out under loan forms and agreements, with replacement fines....but even if something is lost, the money fined will not replace the CT or the work that went into it.....so, having the spare & never using it unless you have to, that's the cheapest form of insurance you can have....

Since you know perfectly what the 2nd copy will look like, why not adding elements like for example a full moon or whatever with a double exposure..

I'm speaking about transparencies. You never have enough of a good thing. If your image was great, process the backup. You'll be happy to have it if your first original gets lost or damaged. You can carry it around and show it off, and not worry. You could file it with a stock agency. If you didn't like your image, don't process the backup. Personally I have three distinct files: first picks, backups of first pics, second picks.

In case this additional $1.5 to process your 4x5 backup sounds expensive, remember that a 4x5 duplicate costs $30.

With all u guys comment, I think I will process those scene that I am satisfied with, and throw away the others.

Roberto's idea is pretty interesting too, I will consider to add something to the unsatified shots.

Thank you all guys! Chin.
