      Today we take colour photography for granted. Taking pictures in full, natural colour is so easy that we don’t pause to consider how it all came about. Yet the search for a cheap and simple process of colour photography followed a long and difficult quest with many a wrong turn and dead end.   The Darkroom Like film, printing paper is coated with an emulsion containing light-sensitive compounds. The negative is a reversal of the tones in the original scene. In order to create a positive within a photographic analog environment, a darkroom is necessary, including an enlarger, easel, safelights and processing trays. Unlike film developing, printing photographic enlargements.

      C41 colour film is perceived as a complex process that requires an expensive Jobo or other specialised equipment. Well, Michael Raso and John Fedele from the Film Photography Project are here to show you that this simply isn’t true in their new video using their C41 Home Developing Kit.   E6 is the name for Kodak's entire process for slide film. It can be bought as a kit or the individual chemicals can be bought seperately. It has nothing to do with processing colour negs. You need to buy a kit to process colour negs - it will contain colour dev,bleach,fix etc ie everything in one box to do the job.

    The cameras that were used to make these negatives and photographs used a variety of film formats and sizes, and we can make prints from them all. Some vintage cameras used roll film in sizes ranging from 2 inches up to 3 inches wide, in formats such as , , and Black and white, color, glossy or matte prints are all the same price.   It is certainly possible to develop color negative and color positive film at home, but there are added difficulties to consider. The Cnegative process itself is much more difficult, due to being extremely temperature sensitive, especially without a basis in developing black and white film.

Real film scanners remove it (in Color Negative Mode) by individually varying the exposure (time duration) of the three RGB channels. For color negatives, the blue channel is exposed about x longer (than red), and the green channel is exposed about x longer (than the red channel).

This simulates an analog optical filter. C41 Color. C41 color processing is the most popular film processing technique for colored prints developed by Kodak.

After that, there is a process wherein the bleach converts the silver to silver halide which will be soluble in the fixer. The final step entails a wash, a final stabilizer, and a rinse to form the perfect colored images. One of the issues of digitising negatives using the method that involves taking a photo with a digital camera is that the RAW file will have a colour signature of its own.

This means that the final colour of the processed 'digital negative' will never be true to the film stock, but it will inherit a bit of the colour signature from the digital. Color negatives were printed by the Type C process while transparencies were printed by Type R. Both R and C type prints opened up the color market for professional photographers as they met the basic requirements of allowing user-processing, relative ease of use, relatively lower cost and acceptable color.

Negatives require the image be inverted, easy enough for B&W, but color negatives also require that the orange mask color be balanced out (it is a strong greenish blue when inverted to positive).
