vignetting on 6x6 with beseler 45 mcrx 75 mm schneider

so the 80 seems to be working in way of i don't see anything on the final print. however, i do still see dark corners while wide open (5.6) on the projection but they're just outside the image area but on the border area (sloppy borders). i'm thinking i shouldn't see that at all because it shouldn't be that tight? maybe something wrong with the enlarger?

it seems the opposite. when I stop down the image circle decreases.

I did not see this post previously. If you really observe what looks like the image circle getting smaller as you stop down that suggests to me that the edges of the light source are the limiting factor, not the lens.

hmm. so does the bulb need to be closer or do i need to do something with the condensers? they all appear to be in the correct position. condensers are belly to belly and look as thought they fit in perfectly.

Most bulb sockets have adjustable positioning, to accommodate for differences in bulb sizes. With the neg carrier in place, adjust the bulb for even illumination on the easel. The small Ilford EM10 meter is perfect, otherwise just eyeball it as best you can.

I don't think the lamp is adjustable in the 45. You might want to double check the condensers.

I don't see anyplace to adjust the bulb unless its hidden and the condensers seem to be in the right position. thanks guys

Are you sure the enlarger head is mounted properly? Having the light source further up or down on the mount than it's supposed to be, it could potentially be the problem.

[thedeuk]

i don't see any other way possible it could be mounted.

Is this a 211 bulb and is that one of the bulbs that the manufacturers have modified the dimensions in recent years?

I did find a manual for the 45m series http://www.jollinger.com/photo/cam-c...eseler_45M.pdf
from this place. http://www.jollinger.com/photo/cam-c...s/manuals.html

Looks non adjustable, but if you aren't using a 212 bulb, it won't be quite correct.
