When I’m not at the computer writing R code, I can often be found at the computer processing photographs. Or at the computer browsing Twitter, which is how I came across Stuart Humphryes, a digital artist who enhances autochromes. Autochromes are early colour photographs, generated using a process patented by the Lumière brothers in 1903. You can find and download many examples of them online. Stuart uses a variety of software tools to clean, enhance and balance the colours, resulting in bright vivid images that often have a contemporary feel, whilst at the same time retaining the somewhat “dreamy” quality of the original.
Having read that one of his tools uses neural networks, I was keen to discover how easy it is to achieve something similar using freely-available software found online. The answer is “quite easy” – although achieving results as good as Stuart’s is somewhat more difficult. Here’s how I went about it.
