One of my favorite internet sites is The Online Photographer edited by Mike Johnston. Mike J. is a knowledgeable and entertaining writer on photography both digital and analog. He also will write on other subjects, many of which I also am interested in. One such "off-topic" post was a very useful article on stand-up desks where he outlined the ergonomic and sizing guidelines.
The area allocated to my digital darkroom is cozy- about 7x10ft. The wall opposite the printer was the obvious location for the new desk. The standing area had to be relatively shallow, otherwise it would feel cramped and cluttered. Over the years I learned that a good way to give the feeling of more space is to have the floors free. Luckily, I still had a pair of 12X13 steel squares that I used for the library shelves installed last Summer. There was plenty of 2X12's and 2x8's to use for the top and bottom. The bottom refers to a base support for a pair of Bisley 5 drawer cabinets. I have another pair elsewhere; they are great for storing printing paper, photos, etc.
The expenditures for this project came from shelling out for a new desktop computer. I had been using a Viao laptop for digital photography and to run a Squeezebox Touch. The latter is a little music server that has great audio quality both as an internet radio source (it can access internet stations not available on iTunes), uncompressed CD files and Hi-Res downloads. It can be linked to either a NAS or a computer from either WiFi or ethernet which comes in handy as it's 30 feet away from my desktop. So, a computer that can serve as both a much speedier Photoshop machine and a music source made for a reasonable purchase. My better half is also happy as she needed a more up to date Windows machine.
Here is the new standing desk.
The new arrangement allows for a 4 foot space between the printer and the opposing desk. By placing the computer at the former desk area, I was able to use the existing cables (except for one Ethernet cable for which I'll need to buy an extension).
In addition to providing a standing area to work in, the new arrangement gives a lot more desktop area than the previous location where the desktop now sits.
Hopefully, my back will improve and I'll be more productive.
