    Short Enlarging Times

    I keep getting very short enlargimg times, always 3-4 seconds at F/11. Negatives look resonable. Other moving to F/16 is there anything I might have overlooked? Using a Beseler 23C with color head.

    With colour head, you can dial in Cyan which will block some of the light but have no effect on the contrast.

    I will look at that. I almost wonder if the enlarger bulb isn't to bright.

    I have never tried a Beseler, but my Kaiser semi-condenser unit with a 100w 12v halogen lamp would require longer times at given aperture and print size.

    Any of the suggestions already given will work but I can't help d feeling that at the print size and aperture you quote there is no way the correct exposure should be so short. So, yes, have a look at the bulb and if you can get a lower wattage then swap. This will avoid having to use " work arounds"

    At 5x7 print size you'd be down to about 2 secs and even at 3-4 secs you cannot possibly do any dodging

    On a color head just add equal amounts of all three filters which is equivalent to a neutral density filter. For example 30Y+30M+30C.

    Cyan filter blocks red and the paper is insensitive to red; it looks dimmer to your eye but it should have no effect as far as the paper is concerned.
