For the sake of this article IвЂ™m also calling this interpolation since it has an impact on the original data of recorded luminance values. Note that IвЂ™m also referring to the addition of color through the CFA as вЂinterpolationвЂ™, which some may argue this is not strictly interpolation.

The interpolations indicated in the red callouts cannot be avoidedВ in both color and black and white workflows with a full color sensor. There are various interpolations in the pure color process that are inevitable to produce a color photograph.It is for this reason that a photographer working in black and white only, will benefit the most of a sensor that has no CFA and no interpolations will be part of the entire process. Therefore it has its flaws that become more critical around edges of a photo and also in areas in an image where colors abruptly change. Despite the fact that demosaicking algorithms are very intelligent, it still is just an algorithm that can make very well educated and accurate guesses. This implies that a color sensor will always miss 2/3 of the information per pixel that will later be guessed! The set of data, containing the red, blue and green data and the luminance values is the actual RAW data file and demosaicking is the process that takes place when we run a RAW file through the RAW converter in Photoshop for example. The discarded blue and green components will later be added through a demosaicking process that interpolates the missing colors to make up for a full color image. If for example light hits the red filter, it will only let through the red color component of that light and will discard the blue and green information. In a Bayer filter there are always more green than red and blue filters since green filters are more sensitive, just like the human eye is more receptive for green. Each colored filter represents a pixel on a sensor and are literally placed on top of a pixel. The Bayer filter is a physical layer placed on top of a CCD or CMOS photo sensor, containing a grid with a pattern of red, green and blue filters that can identify the various different wavelengths that represent the various colors. This articleВ is all about the technical reasons for a correct approach to black and white photography. The article in front of you can be read without reading part 1 of this guide, but I would highly recommend reading part 1В for a better understanding of the artistic reasons behind black and white photography. In another articleВ I wrote how you can combine the best or most valuable aspects of black and white photography with some of the most valuable characteristics of color, namely by working with split tones in a black and white photograph. On the other hand, colors can add to the symbolism and mood in a photograph, which is a way of communicating a message in a photograph, necessary for it to be called art. Black and white is the ideal medium to create and perceive depth since itвЂ™s the art of working with luminosity differences to create a meaningful photograph. Furthermore an elementary difference between color and black and white is that you can only perceive dimensional depth correctly when your view isnвЂ™t distracted by colors. ItвЂ™s best to apply borders only when youвЂ™ve settled on the final picture size and aspect ratio since you wonвЂ™t be able to crop the picture later without losing some of the border.In part 1 of this guide, вЂIn Defense of Black and White PhotographyвЂ™, I wrote about why black and white photography could be used, and gave an overview of the artistic pros and cons of black and white photography compared to color photography.В One of the conclusions in part 1 is that black and white photography is one step away from reality, which is a way of achieving beauty, necessary for art. The Image Borders section has a range of plain, film like or rough edged print border effects which you can choose from the drop-down menu and adjust with the sliders. ItвЂ™s not unlike using the graduated filters you get in some other programs. Burning the top edge is a great way to add a sky darkening effect, and burning the base is a great way to balance up the composition if you do. You can darken (burn) the top and bottom and left and right edges individually or all together. You can achieve more controlled and creative вЂdodging and burningвЂ™ using the Burn Edges section. Vignettes can effectively simulate the appearance of old lenses, negatives or prints. The Vignette panel offers a range of preset corner darkening or lightening effects, but you can also control these manually. You can also adjust the вЂpaper hueвЂ™ and вЂsilver hueвЂ™ separately to create split toning effects. The Toning section offers a large range of preset toning effects, from Sepia to Selenium and many more. This is the last adjustments panel, but it covers a lot of things, not just the finishing touches.
