The problem is: They are mostly obscure, incoherrent and only understood by the student himself, and never intended to be read by anyone else. They are not self-contained and only understood if at all in the context of the textbook. http://www.locolomo.org/erik.norgaard/blog/unlocking_the_mobile_market/?ref=rss 2010-08-12 22:33:13 UTC+02 The letter below was sent to the current (2010-2014) EU Comissioner of ICT, Neelie Kroes. Feel free to copy this letter and send to your political representative to add pressure for an open market. Dear Mrs Neelie Kroes: The EU has made progress bringing down costs of roaming by intruding caps and maximum prices, but I think that these initiatives does not attack the core problem: Carriers are locking down their clients. http://www.locolomo.org/erik.norgaard/blog/film_to_digital/theory_in_practice/?ref=rss 2010-06-04 20:21:26 UTC+02 Theory works in practice! Both methods give useful results. I have tried different film types and found that the colours need different exposure depending on the film type. Fuji Superia 200 I tried both methods of using CTB filter as well as bracket exposure on a Fuji Superia 200 film strip, and both methods give good results. http://www.locolomo.org/erik.norgaard/blog/film_to_digital/post_processing/?ref=rss 2010-05-22 20:14:50 UTC+02 For the post-processing I use PhotoShop, but other programs may work as well. Using the CTB filter produces a digital negative that only needs colour correction and be inverted to produce the final image. With bracket exposure, a digital negative is produced merging the colour channels from different exposures. http://www.locolomo.org/erik.norgaard/blog/film_to_digital/film_handling/?ref=rss 2010-05-20 19:32:56 UTC+02 With all the work done, how practical is this solution? The ES-1 slide holder is designed for mounted slides, not for film strips, and handling the film is time consuming. It is difficult to advance the film strip and get the right crop, in particular because the eyesight only shows 95% of the frame, but I found a solution: Defocus slightly to see the entire frame beyond the crop, then advance the strip to the next frame and refocus. http://www.locolomo.org/erik.norgaard/blog/film_to_digital/getting_consistent_results/?ref=rss 2010-05-20 19:31:27 UTC+02 So all is set. With the project ahead, it is important to be consistent with a procedure to ensure the digital photos can be batch processed. It is important to determine the right CTB filter or determine the exposure difference for each colour channel if using the bracket exposure method. And, it is important to note all these data down if the strip need to be retaken or for use with other films of the same type. Needless to say, always shoot in raw at maximum colour depth and maximum resolution. http://www.locolomo.org/erik.norgaard/blog/film_to_digital/light_box/?ref=rss 2010-05-20 19:30:09 UTC+02 The next problem is to get a stable light source of good quality. Daylight would be great if only it would be stable, if the forecast is stable overcast, this is perfect. Otherwise, to avoid any influence from the changing daylight, shut all windows and use a light box. Incandescent light has a good colour rendering, but is very warm and white balance correction may not produce optimal colours. The problem is that incandescent light peaks in the red colour channel, just where we don't want it. http://www.locolomo.org/erik.norgaard/blog/film_to_digital/camera_setup/?ref=rss 2010-05-20 19:28:09 UTC+02 The first problem is to mount the filmstrip in a plane perpendicular to the lens at the right distance. Film strips has a tendency to bend so they must be pressed flat give a sharp image. The film must be kept at a fixed distance perpendicular to the lens. Nikon has a slide copier extension tube, ES-1, designed for mounted slides, but it does not hold unmounted film. Wayne Fulton at Scantips wrote about scanning slides with the Nikon ES-1 extension, but he does not cover how to copy film strips. http://www.locolomo.org/erik.norgaard/blog/film_to_digital/colour_rendition/?ref=rss 2010-05-20 19:27:19 UTC+02 In theory, it should be possible to just shoot a digital photo of each film frame with a macro lens. But, is not as trivial as it may sound. As mentioned, I have thousands of photos, diapositives, colour negatives and black and white negatives. As for diapositives, this is indeed straight forward, all that is needed is a good light source. Colours will then be reproduced correctly with a single exposure. I might need to adjust black and white point a bit, but that's all. http://www.locolomo.org/erik.norgaard/blog/film_to_digital/?ref=rss 2010-05-20 19:23:01 UTC+02 Since I've made the shift from film photography to digital, I have wondered what to do with all my film photos. The more accustomed I get to the digital work flow, the more that box of film negatives becomes a box of lost memories, a black memory hole from which nothing will ever escape. It would be a pain to resign and let my photos from the last 20+ years float away into the past. I have thousands of photos, colour negatives, slides and even black and white negatives.
