Pinhole Camera

When beyond photography you love the magic of images

CURVA-45 changes the rules of pinhole photography

As on Attaphoto standard, the CURVA-45 provides an extraordinary mix of innovation and tradition with the ease of handling typical of the CURVA cameras range. This is the ideal solution for photographers that looking to an alternative with more advanced standards than the classic wooden pinhole cameras. Compactness, strength, reliability and the new system to space the film, supply greater certainties to photographers who are passionate about pinhole photography. The stenopeic holes of CURVA-45 allow excellent light acquisition, which means more defined details with greater acuteness. The CURVA-45 pinhole camera has a focal length of 45mm and is particularly suitable for detail, close-up and portrait photography. With Curva-45 the risk of photos with overexposure spots from inlet stray light is almost zero, thanks to its black camera "BEAM CUT" light reflections are eliminated at the source and can't spoil the photograph. This to shot great quality pinhole photo.

CURVA-45 is much more than just a pinhole

Beyond the limits of pinhole photography

Film feed system with constant tension

pinhole film feed

In the pinhole camera CURVA-45 the film feed system has a mechanism that makes it irreversible and therefore only allows the film to be wound, keeping it always under tension on the anti-scratch rails. This system eliminates the risk of film retraction even after a long period of camera inactivity, keeping the film tensioned and ready to shoot your photos. Once all the images available on the film are finished, the feed system locks and thanks to a disengagement mechanism the film can be rewind.

Constant image spacing for 36 actual photos

The Attaphoto CURVA-45 is the only pinhole on the market that allows on small-format 135 films, to space of 2mm each image. Thanks to the image feed indicator, you can be sure that the film is 36mm advanced from the previous exposure with the addition of 2 mm to create a gap to the next one. With our system you have the possibility of fully exploiting the length of the film and actually obtaining the number of possible images according to the capacity of the film.

Film loaded easily

In the CURVA-45 pinhole, the film loading system is comparable to the loading systems of conventional analog cameras. The winding roller is equipped with a slot for inserting the tab of the film where at the base there is a tooth for dragging the film through its perforations. With this system the film is perfectly secured to the feed system, so it will be enough to insert the film tab in the slot with the care that a perforated hole in the film is inserted into the tooth and then wrap, nothing easier and safer.

Dioptric with pinhole

Attaphoto has developed a system to drill brass sheets of 100µm (0.0039"), this thickness is optimized for the 24x36mm format used by the CURVA-45. Drilling a thin sheets, on which a anti glare oxidation treatment is performed, allows a perfect management of the light, giving well defined photos.

Prismatic Joint Shutter

The CURVA-45 pinhole camera allows easy opening and closing of the dioptric through a prismatic joint shutter made of composite material with a low friction to allow openings and closures without impediments and reducing the risk of moving the camera during shooting. The shutter is provided with a mechanical stop in the opening and closing positions, assisted by magnetic blocks that have the ability to guarantee its opening position even for long exposures. In addition to the magnet, the shutter is equipped with a mechanical screw stop to secure it in the closed position when the camera is transported or unused, this preventing accidental opening that could allow inlet the light into the camera through the pinhole.
