Over the past couple of years I have probably spent as much time fiddling with the mechanics of cameras as actually shooting. I get into obsessions about what should be possible, work on it, test it, and before long get fired up by something else. The Neretta is a product of this process.

It’s a box camera – an empty black box with a film holder at one end and a lens at the other. Nothing precious, no fancy gizmos. However, since the negatives are 4”x5” it is a practical and tolerant device to use in the field.
The principle is as simple as possible ... wide-angle lenses display great depth of field, and with a wide enough lens you can use the aperture alone to control the focus. Just like the oldest box cameras really, only now with advanced lens technology and fast modern emulsions you can handhold and capture the action. The camera lacks subtlety, but it can be built very easily – a matter of hours if you’re handy with woodworking tools. The only major expense is to find a good lens and to feed it with film.
The camera box originated as a 4x5 pinhole several years ago, and it was a lucky accident that I made the focal length 90mm, long before I actually had such a lens. I use a 90mm Schneider Kreuznach Angulon f.6.8 lens made in 1964. These are fairly common in good condition and at reasonable prices. It gives ample coverage on 4x5, has speeds from 1s to /500, as well as B and T, and stops down to f.45.
The plane of sharp focus is set at 3 metres by the position of the lensboard. A different make of lens might require a shim under the lens or a thinner lensboard to achieve the same. The zone of focus is dictated by the aperture. At f.22, everything between approximately 1.5 metres and infinity is in focus.

It’s more fun than a Holga (probably cheaper, too) but there the comparison ends. With a good lens and the right film, this camera can give you the ultimate in image sharpness if you want it. And you don’t have to focus the camera, just stop down the lens. :D
I used limewood (aka linden or basswood) to make the Neretta because it’s a smooth hardwood. It’s quite easy to work with glues and screws and can usually be found at craft or hobby suppliers in cut strips and sheets. Harder woods, like cherry, mahogany, or walnut, also make very fine cameras, but they are denser than lime, heavier, and a little harder to work and finish. Balsa wood is too weak and lets too much light through.
Some parts, like the view finder and side grip, were picked up second hand. Other bits and pieces, like the cold shoe and the tripod socket, were salvaged from scrap 35mm camera bodies.
The Neretta weighs around 2 lbs, less than a kilo when loaded, most of the weight being the grip and film holder. One of the things that I like most about the camera is its light weight, especially if you compare it with lugging around a Speed or Crown Graphic. It may not be as versatile as an MPP, but then there’s also far less to go wrong. And there are very few cameras around that you can convert from lens to pinhole in a matter of seconds.
Neretta doesn’t have an established meaning. Neretto in Italian means bold-face print, but the feminine of the word doesn’t exist (well, till now) though I’ve discovered that a few people have used the name for their cats !! Translated it might be “cute little black thing” which came about as the first box was black.

If you do a Flickr (http://www.flickr.com/search/?q=neretta&w=all) search you'll find a few shots taken with a Neretta, built by others who have shown an interest. (Just ignore the cats.) The instructions are available for purchase if you contact me directly.
