Version: 0.9.2-final (using KDE KDE 3.5.8)
Installed from: Ubuntu Packages
I'd like to be able to show statistics about all images in an selected folder (with the ability to select multiple folders at the same time...)
Especially I'm interested about:
- how is the distribution of focal lengths (directly and converted to a normal cameral w/o crop)
=> should I buy a wide angle or an tele next...
- how it the distribution of used aperture
=> can I get the f/4 or do I need an f/2.8 lens next...
There are tools that give me that information through the command line, but integrated in digikam would be great (and doesn't the new database scheme support exactly such an query?)
The new database format used with new 0.10.0 release (KDE4) will store these values.
then I did guess correctly.
So I only want an "histogram" of the information in ImageMetadata for all pictures in the selected folder(s).
Doing a good histogram for this is non-trivial:
According to my experience with a home-brew solution,
the bin-width to be chosen very much depends on the number of entries.
Moreover, it can become very spiked. And a separation according
to lenses would be helpful as well.
Also: where should one put such a statistical information?
Maybe another side-bar could carry the needed plots,
together with a selection of all lenses or specific lenses.

Yes, that's not that easy. If there's no easy way to determine the width (I'd *try* e.g. (max-min)/10 or 20...) it could be made setable.
A custom query could help here. How many pictures have a focal length > 100mm?
> Moreover, it can become very spiked.
Why not? I'm interested in the values and not in an "pretty" histogram...

As an option/filter: yes.
But *I* am mainly interested in all pictures at once (as I want to decide which type of lens I should buy next)

I was thinking of a right click context menu (e.g. named "Statistics") - but an side bar also would be fine.
Having read this conversation at flickr
I thought it would be pretty useful and a nice feature to digikam!
So, here comes my vote for this "bug" errrr wish ;)
I saw this link: http://www.cpr.demon.nl/prog_plotf.html

I thought it would be a nifty feature for digikam, and apparently I'm not alone ;-)

I think this wish would be a nice addition.
But I think that first this wish
should be solved, because for the statistics, the proper 35mm equivalent focal length is needed.
Here is an example of what it could look like :
Here is an utility to do that on your flickr pictures:
Now I have the same question / task as 6 years ago - and the new DB should be working...
What's the status here?
*** Bug 286778 has been marked as a duplicate of this bug. ***
This would be such a nice addition, but think the status is that the information is available in the database, but there's no one working on it.
About what was mentioned in comment #8, it looks like digikam shows the 35mm equivalent focal length in the UI, but it is not stored in the database?

Thank you for the bug report.
