    Using Kodak Black-White Darkroom Dataguide

    Would appreciate the insight of experienced Kodak DataGuide Users.

    I'm have the 1979 Black-and-White Darkroom Dataguide
    Edition 6

    On Page 5 The Table of Development Numbers.
    Why are some numbers Light Grey while others Orange Brown vs normal BLACK?

    On Page 7 The Developing Dial
    What is the purpose of the Orange Brown "P" to the left of the dial Triangle Pointer?

    Thanks in advance

    My copy is older than your's and doesn't have most of the features you're speaking of.
    For the development number table, the black is probably the recommended combination, and the grey other possibilities. At least, that's the way it's presented in mine, but mine doesn't have anything in Orange.
    No "P" on the developing dial on mine either.
    There should be explanations of all that in the text though.

    Maybe if you can post some pictures?

    I have the same version

    On Page 5 The Table of Development Numbers.

    I can't find any explanation

    On Page 7 The Developing Dial

    The P is for push processing. See the middle of Page 10


    So I'm 1 for 2.

    There have been several revisions since then to reflect changes in films.

    I suggest that you look up some info on the internet.

    OK - I figured out the colored numbers in the table on page 5

    See pages 12 and 13 on controlling film contrast and go though the example on the top of page 13. Note the statement "Development number from the table is 36 1/2, and the color is blue". You use the corresponding color from the tables below (luminance range, flare) to match the color from page 5.

    Kodak had it all figured out, huh? Man I wish I could go into the time tunnel and be a fly on the way at the Kodak premises back in the day. Probably busier than an ant hill.

    I would second this! I have the same old books, but it is so easy to get current information.

    And, from a reliable source.

    That's for sure! My Dad had all the Kodak booklets, and the information in them is phenomenal. So far as I can tell, NONE of the other photo manufactures came even close to these publications. Sure wish Kodak was like the old days - but then - the world moves on.

    I tell myself if won't be like that in heaven. It's about all I've got.
