Further to my posts on getting a large format enlarger and converting it to use an LED light source, here are some scans of some actual prints produced! The first is one which I'm optimistically calling 'normal' contrast uses both the blue and green LEDs on together. It does appear normal to me: The next print I made was with just the blue LEDs. As can be seen, the contrast is higher: And with only the green LEDs being used, contrast is lower: The negative is 5" x 4" and is one of four I took on the first trip out with my home made camera a few years ago (yes, I only owned two film holders at the time!). It is not particularly exciting but is adequate to test the enlarger out. Prints are 10" x 8" on Ilford MG IV. Steve.
