    A few basic printing questions

    Today i printed a 6x7 negative and have a few basic printing questions. The exposure was at f11 for 10 seconds and also i had to burn the left side for an additional 10 seconds because the lens was inadequate for a 6x7 negative. At first i thought the negative was popping up or down because of the blurry light on the left hand side but i realized it must be the lens. Im using a 75mm Nikon EL-Nikkor and need to get a 90mm or 100mm to cover a 6x7. Are all Nikon lenses of the same sharpness if its a 75mm, 90mm, or 100mm? Is the contrast to much in this print? I like contrast! The film is Adox developed in Rodinal, printed on Ilford rc paper with no contrast filter used while enlarging.

    Thanks..

    On top of a bit longer lens, you must make sure the easel is centered to the lens, negative, condensors and bulbs or you will see fall off as you print indicates.

    Here is a print before the burning was done. Left side issue must be due to the lens on covering a 6x7 negative, am i correct?

    I never had this issue with 35mm, 6x6 or 645.. This only happened with 6x7 and its on both sides of the negative. The print dose not show the right side because i cropped the right side off.

    I think you have some alignment issues happening. Using a 75mm lens would show slight fall off in the corners equally, not offset as your print shows. You need to check that the condensors are aligned as well as the negative carrier and lens.

    Are you cropping the image using the easel?

    I cropped it on the easel. How would i go by adjusting the condensers? Im using a beseler mcrx. When i first received the enlarger i removed the condensers from the metal tube to clean them because they were filthy and i put them back in the order they were removed. I believe they are held down by a snap ring.

    hi cantore

    sometimes enlargers have a secondary condenser, or a different configuration for different format films.
    i have a little durst m601 and you are supposed to change the square condensers when doing 6x6,
    and with the omega d3v ( sort of ) there is a condenser i am supposed to slide under the lamp house
    and above the big condenser lenses ... maybe someone with the same one or knowledge of yours
    can comment about the max. format it is capable of taking, without fall off ( like you are getting ).
    ( i know nothing about besslers )

    nice print btw !

    Bob, Jnan & Rick... Thanks you guys for the advice! I fell like an idiot right now! I made such a rookie mistake and if yous want to hold me down and kick me a few times i deserve it. Yes i moved the easel because i liked the composition of the image the way its in the print. I also did that another time also with a 6x7 neg which made me think it was the format/lens combo. The print is of the lower left side of the negative.. You guys are great and i really appreciate all your help.. I think i will go and put my head under the pillow for a while

    Good Evening, Cantore,

    I also have a 75mm El Nikkor and use a Beseler MCR-X enlarger. That lens will NOT cover a 6 x 7 negative adequately, although it will come close if everything is well centered. You do need to have the condensers set properly to be sure light covers the entire negative; I've added a mark about 1/2 inch above the 2 1/4 x 3 1/4 mark on the scale for use in printing 6 x 7 negatives. Setting the condensers at the 2 1/4 x 3 1/4 mark would cause no problem, just very slightly less-concentrated light--a matter of no practical consequence.

    Konical
