Note: if you want to use the tone equalizer with negadoctor, you’ll need to move the tone equalizer module after negadoctor in the pixelpipe, since the tone equalizer is not designed to work with negatives. Some examples of such ICC profiles may be found in the following forum posts: The working profile parameter in darktable’s input color profile module should be set to either linear Rec2020 RGB, or to an ICC profile representing the actual color space of your film emulsion. When developing the scanned/photographed film negatives, it is recommended that you disable any tone mapping modules such as filmic rgb and base curve. your film holder completely obscures the unexposed parts of the film), you can take a separate image of an unexposed part of the film, measure the Dmin parameter from that image, and then paste that setting to the rest of the images from that film. This is required to set the Dmin parameter (see below).
When scanning or photographing your film negative, make sure you include some unexposed part of the film within the captured image. This reference white balance setting can then be made into a style or simply pasted onto the images taken from your film negatives.Īpply the standard or enhanced camera matrix in the input color profile module. You can take a profiling picture of the light source with no film negative in front of it, and then use the “from image area” feature in the white balance module to obtain a reference white-balance setting. “expose-to-the-right”, so that the histogram in your camera touches the right hand side without clipping the image.Įnsure the white balance is correctly set up to compensate for the light source used to illuminate the negative. When taking the photograph, adjust the exposure to fully utilise the entire dynamic range of your camera sensor – i.e. If the image of the negative was obtained using a digital camera, then in order to obtain accurate colors in the final image, you will need to take the following points into consideration: a light table or computer monitor) or off-camera flash. You can obtain an image of a negative using a film scanner, or by photographing it against a white light (e.g.
