<div dir="ltr">We have 2 entries in bugzilla about this topic to look which area have been focused while shot. The first deal is to read metadata where camera store this information.

This way is used in Darktable. This way is slow of course because whole pixels images must be parsed. </div><div><br></div><div><a href="https://bugs.kde.org/show_bug.cgi?id=314022">https://bugs.kde.org/show_bug.cgi?id=314022</a><br></div><div><br></div><div>As we have already an algorithm to detect blur image, the second point will be easy to implement i think.

<br>
I wonder if it's possible to automatically detect (and maybe mark) the area which is reasonably well in focus of an image, with digikam or maybe with other tools. Any ideas?<br>
<br>
Thank you for your inputs.<br>
