Processing tank option for 4x5 dry plates

For those of you who own or are interested in the Stearman Press SP-445 film developing tank, Stearman Press has released 4x5 glass plate holders which allow you to develop two plates at a time in the SP-445.  The plate holders are available at https://shop.stearmanpress.com/products/4x5-plate-holders-pair

I have worked with Stearman Press over the past couple of months to perfect these plate holders, testing out prototype holders and verifying that development in the SP-445 delivers perfect results.

This is a GREAT accessory which avoids the need to tray develop 4x5 plates in a darkroom, allowing you the convenience of developing plates at your kitchen sink... just like you would sheet film!  I now exclusively develop my own 4x5 plates in the SP-445, and really appreciate the convenience as well as the ability to use my favorite washing technique:  The Ilford archival wash method described here under the "Spiral tank processing method" section (I omit the PhotoFlo step).
