Images unfiltered
The Phase One Achromatic+ is a 39 megapixel medium format digital camera back that provides wide spectrum black and white images with an unprecedented high level of accuracy.
| The Achromatic+ is the first commercially available medium format back that is a true replacement for almost all scientific black and white film types at much higher quality and with far more consistency. Traditionally, most camera sensors have a Bayer pattern of individual red, green and blue filters for each pixel. These individual colors are then interpolated through numerous methods to create RGB data for each pixel. The Achromatic+ back is designed to be a black and white only product with no color filters on the sensor. Different configurations, multiple applicationsThe Achromatic+ is supplied in two different configurations. The first configuration includes a permanently mounted IR cut-off filter that is required to allow the sensor record the human visible spectrum. The second version is supplied with no IR cut-off filter and is therefore capable of recording into the visible as well as the infrared and ultraviolet parts of the spectrum using interchangeable filters. |

Achromatic+ for black & white photography
The process of reproducing original black and white prints is extremely difficult with a full color process. The Achromatic+ back can reproduce original black and white with extreme accuracy that requires little or no post-production. The lack of filters on the sensor also provides the advantage of higher resolution. To take advantage of the extra resolving power, high-resolution lenses are required. Reproduction lenses are typically higher resolution thereby allowing the Achromatic+ back to provide the best quality possible. Improved optical performance can be achieved with special spectrum illumination systems, which have been developed for use with this imaging device.
Achromatic+ for scientific applications
For Scientific purposes, filters can be used to restrict the captures to specific wavelengths thereby recording specific information. The use of filters to record the restricted wavelengths also have the safety advantage of allowing researchers to work in full spectrum light. With Infrared film, all visible light had to be removed and the film was extremely difficult to handle and work with. The Achromatic+ back can record infrared in regular daylight or existing light because the optical filters, not the capture medium, defines the range of electro magnetic spectrum recorded. Check the Tech Specs for information on how to operate the Achromatic+ with interchangeable filters.
For instance the Achromatic+ can add value to work in medical and agricultural segments, where organic specimens can be either designed to reflect a specific wave length spectrum or may reflect differently depending on age or growth condition. Similarly the Achromatic+ can add value when working with forensics, quality control and other applications.
New opportunities
Possibly the most unusual and most inspirational value of the Achromatic+ back photographically, is the ability to shoot with no filters and record IR and visible spectrum down to UV. This can lead to images that are truly exciting for Fine-Art photographers.
