![]() The C-41 process, as the developing standard for color negatives provides relatively constant results, as long as developing times and temperatures are being met. Why doesn't ColorNeg contain any characterizations for black and white films then? We will provide you with an astonishing side by side comparison on the next page that will prove our point visually. The negative effects are less obvious here than they would be for color images since monochromes as such mean a greater degree of abstraction from a natural representation of a scene. Photoshop's incorrect approach in calculating inverse pixels will inevitably lead to inferior monochrome conversions. If you are interested in a complete mathematical analysis of this issue please feel free to study our technical report Negative to Positive. What this boils down to is that Photoshop subtracts where it really should divide. The addition / subtraction of such density values equals the multiplication / division of intensity values. Assuming we are working with a linear scan in Photoshop the invert command is being applied directly to intensity values, while it should be applied to density values instead. What is additive instead for photographic film are densities. For this method to be correct the negative's intensities would have to be additive which they are not. Photoshop's invert command will subtract the value that is to be inverted from the maximum value possible. What really is to blame for the inferior quality in inverting negatives using Photoshop are wrong calculations. Any such mask can be removed easily enough. Why not simply convert monochrome negatives using Photoshop?Īs we have illustrated before, the assumption that a color negative's orange mask is to blame for inferior conversions in Photoshop is wrong. The combination of traditional black and white negative film with ColorNeg, multiple pigmented inks and the best fine art printing papers available offers more control over your imaging process than ever. These positives can then be edited further to suit your artistic needs and finally be printed using cutting edge fine art printing technologies. ColorNeg allows you to convert your valuable monochrome negatives into perfect positive images exerting the maximum of control in the process. Among our users many professional photographers use ColorNeg also, or even exclusively, for their black and white work. ColorNeg is the ideal tool for working with your monochrome negatives in PhotoshopĮven though ColorNeg has primarily been developed to convert color negatives it is also ideally suited for working with black and white material.
