Very recently I’ve been experimenting a little with RawTherapee for my raw file conversion. I used it quite some time ago but have come to appreciate it much more recently, presumably as I’ve learned to understand a lot more about digital photo processing. There is not much that it doesn’t do. This particular photo has been sharpened a little bit using RL Deconvolution rather than the somewhat traditional Unsharp Mask. From what I’ve read, rather than specifically targeting edge contrast like Unsharp Mask does, deconvolution mitigates effects such as blurring caused by anti-alias filters which results in less of a ‘halo effect’ around edges and more of a ‘film like’ sharpness which looks far more natural. I’m sure it’s supported by most (all) non-free raw conversion sw. Other tools that I use like Digikam have other strings in their bow such as the ‘Refocus’ sharpening algorithm. I’ve found this to be pretty good in the past but I compared this versus RT’s RL Deconvolution on a PNG of this image and there was absolutely no comparison as to which looked better – certainly in my opinion anyway.
