Scannerless Digital Capture and Processing of Negative Film Photographs

Remember the film era? It’s demise began setting-in roughly two decades ago, and about all that’s left is a reduced stable of good scanning hardware and those millions of negatives in countless personal and institutional collections that many people really intend to “do something about” – “one of these days”. The problem is that the truly high quality film scanners of yesteryear are discontinued or cost a small fortune, those that hit the resale market are also expensive, and those that people own will become increasingly difficult to service as time marches onward, parts become scare and experienced technicians retire or pass on. The “digital revolution” from capture to print has taken-over in a remarkably short period of time.

The technology that won’t be disappearing any time soon is that useful for photographing the film media with a digital camera and processing the files with imaging software. While there’s nothing new about this idea, Mark and Todd decided that given the latest equipment and software now on the market, it could be worthwhile revisiting this approach. They invested considerable time and effort (and some money) exploring fresh approaches, and as a result have achieved their objective of developing two workflows that produce truly good results with little work. The focus of their research is on colour and black and white negatives; however the same techniques could be used for positives without the inversion step.

While the camera-based approach is easy enough in principle, in practice there are numerous factors to deal with, and those inform the content of the article. We are providing it HERE as a PDF download, because it has 36 pages and contains much information that will provide off-line guidance to those who try implementing these techniques.

The article opens with a discussion of camera equipment and set-ups for this kind of “macro-photography”. Key considerations include cameras, camera and media set-up, magnification, lens specifications and quality, media flatness, vibration, lighting and its impact on grain and defect reproduction, focusing, and exposure. Mark and Todd each have different set-ups, but they do the same things. A “novel” feature of Mark’s set-up is the use of the new 24 MP Sony a6000 mirrorless APS-C camera equipped with the new Zeiss Touit 50mm “Makro” lens and the Sony “Play Memories” remote control utility for iPhone. Todd is using a time-tested Canon DSLR 5D Mark II full-frame camera with Canon Macro lens. Todd’s light source is an electronic flash and diffusion glass, Mark’s is a light table providing near-neutral diffuse lighting.

Following the discussion of set-up and exposure, Mark and Todd each demonstrate and explain their post-capture processing approaches, which are different; but again, both delivering fine results. Mark approached the research by asking himself how to develop synergy by combining the strengths of several applications, each of which was designed to address one or more of the workflow requirements at hand, such as creating linear TIFF files from raw files and inverting negatives to positives. Todd approached it by asking himself how he could tame everybody’s favorite 800 lb. gorilla, “Photoshop”, to produce good results as painlessly as possible.

Mark describes a workflow using two applications: “MakeTiff” (ColorPerfect), followed by SilverFast HDR8 (LaserSoft Imaging AG). Todd describes a total workflow self-contained within Adobe Photoshop CC. Todd provided a Photoshop Action (download links below) to take users quickly through the first four steps of his procedure. Both of these discussions take the negative capture through raw conversion, negative to positive inversion, and tone and hue adjustments – all that’s needed to make the photo pretty close to print-ready.

We do not provide any judgment about which approach we think is “better”, because they both work well; readers simply need to decide for themselves which to use – we think based largely on personal preference and the software they either already use or wish to acquire. Digital imaging is rich in options and ways of combining the strengths of various products to produce good outcomes. This article is surely not exhaustive, but we have tried various combinations of techniques and software and what we present here is what we decided worked best in terms of quality, speed and convenience.

Regardless of the approach used, the resulting image files can of course be purposed to one’s preferred medium for print, web or device viewing.

Post-Scriptum: (Mark speaking);

The downloadable article is a technical piece with no mention of costs, or costs relative to results for different options, say between cameras, between software, between scanners and cameras. That is intentional because there are very many options for implementing these approaches and their costs will vary by user because much depends on what one posseses to start with, added to which – comparing relative cost with relative quality of outcomes is doubly difficult for the same reasons. As well, the range of options is a moving target. Just while this research was underway, Epson launched a new higher-end prosumer photographic scanner – the V800 or V850 Pro for less than $1000, which the company says embodies significant improvement over their already not-so-slouchy V750 Pro. The macro-lens alone for my Sony a6000 that I used for the camera scans in this article costs about $1000. Which solution is a better expenditure of $1000? Stay tuned.

Mark has been making photographs for the past six decades and started adopting a digital workflow in 1999 first with scanning film, then going fully digital in 2004. He has worked with a considerable range of software, equipment and techniques over the years, accumulated substantial experience as an author, educator and communicator in several fields and is a frequent contributor to the Luminous-Landscape website. Mark developed a particular interest in film scanning and authored the ebook “Scanning Workflows with SilverFast 8, SilverFast HDR, Adobe Photoshop Lightroom and Adobe Photoshop” available on the SilverFast website. In his “other life” (the one that pays for the photography), Mark is a retiree from the World Bank Group and now a consultant in electric power development.
