I could never get the hang of DarkTable, and instead use rawtherapee.<p>Mostly I like rawtherapee because it can be pointed at a directory of .CR2&#x2F;raw files, be used to filter them, convert them, and makes zero attempts to be an image-manager.  I don&#x27;t want to import my images into a collection, or tag them, etc.  Instead I use a filesystem hierarchy for that purpose:<p><pre><code>    Images&#x2F;2015&#x2F;
    Images&#x2F;2015&#x2F;10&#x2F;
    Images&#x2F;2015&#x2F;10&#x2F;15-Helsinki-Sunset
</code></pre>
Each of my &quot;event&quot; directories contains RAW, JPG, and thumbs.  That in combination with the year&#x2F;mon&#x2F;day-title directories lets me find things very easily.
