… is a simple application to help manage offline (as in non-cloud) collections of RAW and processed pictures. It doesn't replace your RAW processor (e.g. Adobe Lightroom, DxO PhotoLab, Capture one, Darktable, etc.) but instead acts as a companion to it, giving a parallel view on all your files.
Corydalis is also an image and movie viewer, designed to work across and understand your entire photo collection; the desktop-only viewers (e.g. Geeqie) are folder-based, not collection-based. This aspect aims to offer a similar experience of viewing your photos and movies as it would be if you stored them in the cloud (but many features are still missing).
Is it for you? If you need/could use:
- help in understanding a large collection of pictures, or
- an image/movie viewer for browsing the pictures stored on your NAS from various web and mobile clients,
Then maybe yes. Although this is very much a work in progress, and has very sharp edges, I use it to analyse my picture collection since ~2013 and as my main image viewer since mid-2017.
On the other hand, if you never shoot RAW, or if all the pictures you take are stored in the cloud, then this is probably/most likely not for you. I personally prefer to manage and be able to browse my pictures without internet access - the entire web interface (fonts, CSS, etc. is served locally, without relying on CDNs).
There is a demo site at demo.corydalis.io, using a few pictures from my own collection; you can use this to see approximately what Corydalis does and how does it look like.
What it doesn't do
It doesn't actually modify your collection in any way. In other words, it's not a "collection manager" (the way e.g. Adobe Lightroom is), but rather is designed to work in conjunction with the actual manager.
Installation and use
You will need stack, a number of common command line utilities, and to read the installation guide. Then read the manual in order to understand what Corydalis shows. You can also see the documentation online at readthedocs.
