Hi everyone. Answers given number by number (separately) will be appreciated.
Expanation: I am photographing old -- 1941 -- documents, including one created with a blue typewriter ribbon on slightly yellowed but high quality rag bond paper. Files will be JPG Fine, not RAW. BOTH typewriter blue ink and paper yellowing must be faithfully rendered at around 500% enlargement on a calibrated computer monitor, and with custom color prints. The printer staff says their machines give maximum true rendering from JPGs in a PDF, and I do not have to convert the files to CMYK.
So, the questions:
1. The usual way indicating how warm or cold flashtube output will be is "color temperature" --- but is "color rendering index" also specified somewhere in Nikon's data stash, or available from a factory tech rep via their website chat?
2. I have an SB 600 and an SB 500. I will NOT be using the SB 500's LED option. Aside from output power, is the color spectrum of the flashtubes identical?
3. If not, and you happen to know the precise spectral difference --- either as color temperature OR color rendering index -- can you please include that in your answer?
Thank you in advance, as the cliché goes. (BTW, if further info is needed from me, I must be away from this forum until around 7 PM Eastern US time.)
