Like most people I have loads of 35mm slides and negatives from days gone by. Would like to hear of available methods of converting them to digital images for sharing with family/friends. Would prefer the cost to be reasonable.
You can use a scanner, or you can use a camera and a macro lens to rephotograph the film. Both methods have their advantages and disadvantages. Of course, you can also use a service bureau, but good ones are expensive and inexpensive ones are usually AWFUL unless you have really low standards.
I used to run an elaborate film scanning operation in a major school portrait company (from 2000 to 2005, when we were transitioning from film to digital capture at the camera). I also used to run an audiovisual production lab in a corporate setting, where we used slide duplication setups... essentially rephotographing film on film. So... Having done it both ways, I know the pros and cons of each method.
It is difficult to find a flatbed scanner that makes REALLY SHARP scans. But flatbeds DO often have Digital ICE software, which can remove dust spots and surface scratches from some types of film, and other software routines that attempt to restore the original color of faded prints, slides, and negatives. A dedicated film scanner is usually nice and sharp, but also likely to be slow, outdated, incompatible with modern operating systems, and considered obsolete by its manufacturer, unless it is VERY expensive.
Re-photography with a macro lens can yield great results quickly, but generally requires post-processing of raw files for the best quality. It is my preferred method, because I don't have the money for a really good dedicated film scanner, and I already have what I need to copy slides and negatives with my camera and a macro lens. Here is what you need, from one end of the setup to the other:
Digital camera on an adjustable slider
Macro lens capable of copying an area of a slide or negative SMALLER than the slide or negative
Plano-parallel negative carrier or film holder or slide holder or all three
Color accurate light source (PHOTO quality CFL or LED lamp with really even diffusion material in front of it)
Suitable rig to hold it all in alignment
Old slide duplicators such as the Bowens Illumitran 3 can be used. An enlarger color head, inverted, with a film holder over the light source, can be used with a conventional copy stand for the camera setup. Or, you can build your own rig. Photograph the film with the emulsion facing the lens. FLIP the image in post-processing. Then INVERT the image or REVERSE the CURVES. Then crop it. Then adjust color and tonality with every tool that works for you. Much of this can be handled with a Lightroom preset, or a Photoshop Action. Then you tweak, spot, etc.
Whichever method you prefer, I recommend a StaticMaster brush, Ilford Antistaticum cloths, Dust-Off or similar "canned air" and Photographic Solutions PEC-12 film cleaner be parts of your film cleaning toolkit.
