Testing enlarger lens coverage

When buying enlarger lenses, it is important not only to choose a lens of the right focal length to give the required magnification, but also sufficient coverage to cover the negative without vignetting. The rule of thumb with enlarger lenses is: Focal length Typical coverage 50mm 35mm 75-80mm 6×6 100-110mm 6×9 150mm 5×4″ I decided toContinue reading “Testing enlarger lens coverage”

Another LED upgrade to the De Vere 54

I’ve owned a De Vere 54 enlarger for a few months, and in that time I have modified it several times. First I spruced up the bulb-powered condenser head by converting to diffusion and making it use a halogen reflector lamp. This proved unsatisfactory and I couldn’t get the illumination even enough. Plus it wasContinue reading “Another LED upgrade to the De Vere 54”

Further modifications to the De Vere 54

A few weeks ago I made the jump to large format photography, and upgraded my LPL C7700 medium format enlarger to a De Vere 54 large format. The C7700 is a fairly sophisticated machine from the 1970s/80s, while the 54 is a primitive beast, cast in the fires of Mordor back in 1952. It neededContinue reading “Further modifications to the De Vere 54”

Converting a De Vere 54 condenser enlarger to diffusion

I recently picked up a De Vere 54 enlarger for a bargain price. It’s a 1950s machine, designed to take 5×4″ negatives. In order to use the light most efficiently when making large prints, the enlarger is fitted with a condenser to give parallel illumination to the negative. However, the flip side of a condenserContinue reading “Converting a De Vere 54 condenser enlarger to diffusion”

Enlarger bulbs for the Durst C35

Today I bought and collected a second-hand Durst C35 enlarger. It needed a new bulb, and the manual says very little about bulbs except you must use a MELAMP 55. Users in some forums, including this one, say that compatible bulbs are difficult to find, or expensive. A little research tells me that the correctContinue reading “Enlarger bulbs for the Durst C35”
