    Perspective Correction in the Darkroom This article defines perspective control in photography and how perspective corrections can be applied in the darkroom.

    The Poor Man’s Halliburton Case I’ve never been satisfied with a single camera case for all the formats I use on camera outings. There’s just not a one-size-fits-all solution for me. For some years now, I’ve taken to DIY camera case customization to accommodate a particular camera kit. As a result, I have multiple cameras…

    My darkroom paper safe has, for decades, been a small DIY wood cabinet with some shelves inside. I have never trusted it to be light tight, so I kept all the paper and test strips stored inside in black plastic envelopes like the ones paper and film are packaged in. The hinged door was held…

    The Availability of High Quality Affordable OC Safelights is Dwindling If you’ve done any safelight shopping these days, you’ve probably noticed that new OC colored darkroom safelights aren’t as plentiful as they once were.

    Most articles that talk about enlarger alignment tell you how to do it, but don’t explain how it can be a never ending battle.  For me and my two Omega D5s, the mechanisms that throw my enlarger out of alignment are drop-away baseboard tabletops and different negative carriers. Quick enlarger re-alignment tweaks take less time…

    If you’ve been involved in darkroom photography very long, you already know that corner-to-corner sharpness of a print made using an enlarger requires a properly aligned enlarger.  That simply means that the negative, lens board, and baseboard are all parallel to each other.  Tools are available to help verify and adjust the alignment of your…

    Have you ever made a big enlargement where the enlarger head was so far above the base board it was impossible or too awkward to reach the enlarger focusing knob while looking through the grain focuser?  I have and decided to find a way to make it easier with a DIY focus extension lever. There…

    Background In my last article, I conducted some temperature tests using the 250W PH213 lamp in the Omega DV Condenser lamphouse.  Omega offered a blower for the DV lamphouse that permitted use of 250W bulb. The Omega part number is 412-020.  I’ve never seen one, but it is listed on the KBH Photografix website. As expected, with…

    Background If you have an Omega 4×5 variable condenser enlarger, you probably know it is common to use 75W and 150W bulbs in them.  These enlarger bulbs are designated #211 and #212, respectively.  Often they are referred to as the PH211 and PH212.  You may also know there is a brighter alternative that will physically…
