    It's not as much fun as making one yourself :-)

    If you end up getting a commercial box, it's worth taking the time to insert the optional glass overlay. It cleans easier, can be cut on and will prove more durable than the composite sheets. I've got a small 8X10 portable Testrite that is handy for taking out to a work table to spread out projects. I also am building one into my darkroom countertop as I'm accustomed to using at work. That way, the area serves a dual purpose and is always in the right spot in the darkroom.

    I found an 11x17" X-Ray Viewer at the local landfill.. Working tubes and all.
    At my previous job they had one built out of wood and frosted plexiglass with fluorescent tubes inside.. Really simple but it worked just fine! Plus you can build it to your own dimensions!

    Also, if you plan to judge color balance on transparencies, be sure that you find a light source with a high CRI (color rendition index) and a color temperature of 5000K to 5500K. Manufacturers of flourescent lamps often indicate that with a model number that includes the number 50 or 5000 in the name, like the GE Chroma50. Regular "daylight" flourescents are _not_ what you want for judging color. I'd give you more specifics if I knew the Australian market. There are even some 5500K LED light bars available on the web, which I plan to use on the next small lightbox I make. www.superbrightleds.com

    I agree with Lee L about judging color with daylight fluoros. We judged little childrens smiles on Portra 120 NC, not color.

    Those LED lightbars look like a great idea, please let us know how it works out!

    Sometimes you can find a good light table from a local printer going full direct to plate output. I've got one thats about 24"x36". It was a pain finding a good spot for it in the darkroom but a glass top table can be used for many different things.

    Nicole,
    Use "garden flourescents" they are 5500K plus and very near to noon day
    sun light at 6000K

    Instead of a lightbox, consider placing a piece of tracing paper @ 20 cents behind the neg sheet and holding up to the light.

    For a more up market version, get a couple of 12v 12 inch flouruescent automotive work lamps and put them behind the tracing paper. That's better than a light box :-)

    Nicole,

    Last year I built a light box based roughly on ideas I got in the book Build Your Own Darkroom by Lista Duren and Will McDonald (ISBN 0-936262-04-4). The plans are outlined in Chapter 8. I modified my dimensions significantly (20.5"L x 15.5"W x 6"H) and the light layout to accommodate easily found fluorescent light size and types. I used two (2) 16” Phillips Natural Light tubes and a mirror type Mylar auto tinting film as the reflector material inside the box (aluminum foil is not recommended). The top surface is white translucent acrylic. It turned out to be a great size light box that can handle 36+ slide selections very nicely yet remain very portable. What surprised me is the cost was almost $50 (including bulbs!). As a DYI project I thought it would be less expensive. I will try to post a simple picture below …Andrew
