    Yesterday I picked up an Opemus 5 with colorhead. Until now I have used an old Opemus standand fully equiped with aftermarked filterholder beneath the lens. I'm used to do splitfilter printing with that and have no experience or knowledge with colorheads at all. I know this is the photo equivalent to jumping out of an aeroplane without checking if you have parachute first.
    I do know the max contrast is about 4 with the colorhead but is there anything other than that I should be aware of when printing with this head.
    Is the difference between the old condensertype and the "new" one large when it comes to results eg. sharpness, gradiation etc ?
    Regards Søren

    Colorhead

    Soeren-I have an excellent article from Photo-Techniques magazine that will help you to integrate using a color head for B+W papers. PM me with your address and I'll copy it and send it off to you today in the post!

    Spit printing with a colour head:


    1) Low grade is max yellow

    2) Highest grade is max magenta

    That's it.

    How do you know the head will only hit grade 4? Have you tested it?

    No I haven't tested it since I only got it yesterday but acording the material I have read so far eg. Ilford and Forte paper spec sheets it only reach grade 4. Hmm now I am in doubt, does it reach 4.5 or even 5 ?
    Ok if it hits grade 5 thats only added bonus for me :smile:
