"(...) What Problem(s) Does The Achromatic Solve – and Create?
For institutions and researchers who require the highest levels of resolution, who don't need full colour, who need to be able to record into the infra-red, as well as those who have the need to record images at very specific optical frequencies, a camera such as the Achromatic fills the bill.
For landscape and nature photographers it is the answer to a question that many knowledgeable photographers who work in B&W have been asking – why can't we have the optical purity of a monochrome camera and regain the resolution lost to the Bayer pattern filtering?
If you used to (or still do) shoot B&W film then you know that you can use certain filters in front of the lens to create desired pictorial effects. A red or orange filter to darken blue skies and make clouds stand out, a green filter to lighten foliage, and so forth.
But, for those that shoot digital in colour and then convert to monochrome during processing, this isn't necessary, because we can use controls such as Channel Mixer in Photoshop, or the Grayscale Mixer in Lightroom to vary the luminance levels of various colour channels and achieve much the same effect.
With the Achromatic back we're back to the same field practice as when we shot B&W film (....)
