Hi fellow LF Community!
I've been trying to troubleshoot my Saunders/LPL 4500-II set up - it may be a simple solution, but I've been unfortunately stumped for the last couple of days! Had no issue printing 35mm or 6x7 on my set-up, but once I decided to print my 4x5 negatives I ran into a problem on the enlarger where the light projection is uneven and smaller than the print size. I am unsure if this is a blockage issue related to the negative stage plate or something else. I've included some pictures and measurements below of my set up for context.
To further technically clarify my set-up - this is a Saunders LPL 4500-II. Lens = APO 150mm Rodagon N. I am using a LPL 4x5 anti-newton glass carrier, the negative stage plate is the masking attachment version (for reference - http://store.khbphotografix.com/Mask...Enlargers.html), not the standard negative stage plate (for reference - http://store.khbphotografix.com/Nega...Enlargers.html).
The images I included show the negative, my enlarger set-up, the lens w/lens board, contact sheet/print, print with the light loss where the chin and the top of the head is obscured, the easel (set for a 8x10 print) and another easel shot, but with the negative carrier rotated on the negative stage plate. With the shape of the blockage, I think the problem is with the negative stage plate as you can see in the photograph. From the negative stage plate-to-the-lens board measures ~ 8 5/16 in; Lens Board-to-Lens measures ~ 1 7/8 in and the Lens-to-Paper measures ~20 inches.
This post has the first initial images and my subsequent one will have the rest! Thank you for reading and hope to hear from the community. I hope it's an easy fix and perhaps one that I simply overlooked! Let me know, thanks!
