During printing a darkroom printer will remove the mask by color filtration. As all three color emulsion layers of a negative film will show different densities, the resulting combined appearance of the film will look orange. It will change the way Negafix is correcting the "Orange Mask". Sometimes this even requires changing towards a direction that initially seems wrong.Īnother important slider is the "Tolerance" slider. If the look of the preview is however not according to my taste, I start moving the slider until I get the look that I want. When setting the exposure slider, I normally start at a value which I think is right for how I exposed the scene. This is not compensating for wrong exposures it is more step towards getting the tonal response curve right. Going to the right the image will however brighten, while moving the slider to the left will darken the image. Generally speaking the exposure slider is not changing scanner exposure its changes the way the information is interpreted. The exposure slider will also compensate for the dense negative that comes from overexposure and will adapt the tone response curve accordingly. Using the exposure slider you can compensate for this. Overexposing Kodak Portra for example normally results in a slight yellow color cast. When we over- or underexposure a scene we have to deal with certain color shifts as the color layers of the emulsion show individual sensitivities. As I often measure for the shadows I probably get even better results with higher settings as the scene was overexposed even stronger due to the method of measuring. As I have used the EI (exposure index) of 200 I should at least select 1.0 with the slider. This slider will shift the profile curves according to the used exposure index. The profiles are the first step towards the final scan. This helps me to get the best results from my scan. NegafixĪfter selecting the scan area first thing I normally do is to select the correct Negafix profile. If large parts of the carrier or holder are included inside the frame chances are that the the colors are not right from the beginning. The red frame will not only determine the scanning area but it will also tell Negafix which pixels to look at. These profiles will ensure a good starting point for your scan. The LaserSoft Imaging engineers have put a lot of effort into this tool and they created film profiles. Negafix is a powerful tool that will take care of negative inversion, contrast and color curves as well as orange mask removal. In order to allow the Negafix algorithms to work correctly we need to make sure that we define the scanning area with the red frame inside the exposed area of the film. Here are the steps I do in Silverfast followed by some tweaking in Adobe Lightroom. I might come up with a special blog post to explain this solution in detail.Īs I have mentioned in my previous post, Silverfast is my dedicated scanner application as will give me the best scans from my Epson scanner. The support compensates for the wrong distance between the lens and the film and provides sharper scans. I now use a Lomography Digitaliza frame with a self made support. During the last month I optimized my mounting solution for the Epson V700 scanner. For scanning at home with a consumer scanner, mounting is crucial. Below you can find a comparison between these two minlab scans and the Epson scan I did later at home after I received my negs back. The lab provided me two scans, a XXL Noritsu scan and a Fuji Frontier XL scan. Scanningīack at home I was very happy how this shot turned out. The strong linear perspective of the composition was chosen to draw the viewer into the scene directly to the iconic tram which was waiting for the first passengers. The Carl Zeiss Planar lens of the Rolleiflex shows an incredible amount of detail and sharpness. I normally rate Portra 400 film at an exposure index of EI 200. The increased exposure time was to compensate for the reciprocality failure of the Kodak Portra 400 film. and I exposed it at f/8 for a little longer than 45 sec. The measured exposure time for the scene was 15 sec. I found this street scene and I was immediately caught by the interesting composition. It was a cold but very beautiful morning in San Francisco and only a few people were on the streets. I had my Rolleiflex 3.5F mounted when I was roaming around the streets. Castro is one of the most colorful and interesting neighborhoods of San Francisco and always worth a visit. I took this image very early in the morning in Castro.
