Rating based on quality or content? Ideas, comments?

Johnny
While rating pictures I always struggle to be consistent, mainly because
I am struggling whether to rate the picture for it's quality or it's
content.

In particular considering that the quantity of digital images have
increased drastically the last few years, making the differentiation of
quality and content less acute - there is normally a quite good quality
picture that also represents the situation or motive it is intended to
capture. However, earlier years albums have fewer pictures, of sometimes
quite poor quality to be frank, but the rarer the picture and content,
the more precious in a way, so I'd like to rate "content" as high, while
rating "quality" as poor.

Does anyone else recognize this, and if so, how do you deal with it?

Now, I could probably do a separate tag structure for this, but it would
be ideal to have two separate star-ratings, and e.g. pass through the
collection, using C-[1-5] for quality rating and (maybe) M-[1-5] for
content rating.

I am looking forward to hear fellow Digikam users opinions and ideas!

Cheers!

I try and rate on content, and delete if quality is insufficient. So for me,
there would no need to go back every so often to adjust the 'quality' tags
(which is what your system would require). Also, a borderline quality that is
kept, has value, so wouldn't be deleted anyway, why complicate things with two
ratings (I'm not a professional, so no problems related to selling pictures)?

In digiKam 2.0.0, i introduce Color Label Tags. With this, you can use
it in your workflow to indentify quickly good and bad items.

Look there for details :

I have some scanned photos managed in Digikam as well, e.g. a photo of
my great-grandfather as a child, however the quality is pretty
bad. Rather, compared to some of the latest diving pictures I took last
vacation with great macro and vivid colors (after some touh-up in Gimp),
the quality could be said to be horrible. However, diving photos (and
other recently taken pictures), I have loads of, while old (e.g. family)
picutes, I have very few.

> So for me, there would no need to go back every so often to adjust the

No, on the contrary. My great-grandfathers photo would simply rate 1 on
quality, but 5 on content. However, the diving pictures would rate 3-5
on quality, and 1-3 on content (except that close-up of the mandible of
the great white maybe...)

> Also, a borderline quality that is kept, has value, so wouldn't be
> deleted anyway, why complicate things with two ratings
Agree, but even if it is not deleted, it is not easily identifiable. I
sometimes want to see my pictures with precious content (e.g. reunions)
and at other times with great quality (e.g. showing off :)), and
sometimes both (for printing that family album).

> (I'm not a professional, so no problems related to selling pictures)
Concur!


Thinking about it, it is similar to a risk register; one one axis you
have the probability, and on the other the consequency. For pictures
this analogy would be quality - content, where pictures in the lower
left corners are candidates for deletion and the upper right ones are
for the albums.


 Quality
          |                  Few lucky
          |   Awesome pics     shots
          |      here
          |
          |
          |
          |
          |  Crap          Precious
          |  Here           pics here
          +-----------------------
                                 Content


Sorry, I am going off on a tangent here...

This looks interesting indeed, but it is not exactly what I
envisioned. Having thought a few seconds more, maybe a scheme with
custom ratings could be useful? I jotted down a reply to Viëtor, but
that seems to have gotten stuck somewhere, but I like the idea of
something number based. If any number of custom rating criterias could
be used (i.e. in the database have several rating tables on different
citeria and allow switching between), and use a custom accelerator key
for different ratings, like the C-u (this could possibly already be done
with 2.0 by assigning keys?).

One could then create unions and/or cuts of different ratings, i.e. as
my preference would be simply content and quality something like:

quality

      | Show-off        Lucky/Great
      |   photos          shots
      |
      |
      |
      |
      | Awful          Memorable
      | shots           shots
      +------------------------
                                content

E.g. lower left are candidates for the bin, upper right will go in the
photo-book for printing.

Again, I am rambling, but this seemed a good idea at the time...

Re: Rating based on quality or content? Ideas, comments?

Bugzilla from rogersjd@gmail.com
To the OP: great topic here! I have the same goals (uniform rating
across years of albums) and same problems (my photography skills
improve and quantity goes up, changing the thresholds). I have a rare
shot of a pygmy owl in the wild that may be the only picture I ever
get of said creature in my lifetime, but it's camera-shake blurred
with poor light. Then I have a stunning picture with beautiful vivid
color of an.. ugh.. robin. How to rate these? :-)

So I for one like the idea of maybe two rating fields that would be
fairly common to all, i.e. quality and content ratings. The above
graph is 2D, so the lower left ratings are 1/1; lower right 1/5, upper
right 5/5, etc. But then for those who want other criterion beyond the
common quality/content ratings, the ability to have custom rating
fields would be neat. It would be like a tag that could be assigned a
value, perhaps with customizable number of degradations.

Sounds like this would be an interesting feature. The problem with
tags is that they are inherently binary, either the photo has the tag
or not. You could do a poor-man's version by making tags content1,
content2, etc. The only problem is that it's not as easy to filter by
a threshold like the star rating, and you would need to OR all tags
you want to display.

I also set out to do the same thing early on, using tags. This was because I was getting a lot of poor shots of rare birds. I wanted to flag them as good shots, because they were worth keeping, but wanted a sub score to rate them to find the best of them.

The colour labels should help a lot, and I'd try them when they become available rather than suggest alternatives.

It's good to hear others have the same workflow, and that it's being addressed.

Perhaps are you talking about Pick Label Tags (similar than LightRoom,
Aperture and Bibble.

There is an entry in bugzilla :

https://bugs.kde.org/show_bug.cgi?id=241847

When Color Labels will be done (90% complete), i will implement Pick
Labels in digiKam 2.0.0

Yes. I implemented Tags Keyboard Shortcuts since 2.0.0 beta2

No, I think this is a different concept.

I like the idea of linear tags! After all, that is what the star rating is
anyhow, a linear tag with a user-defined tag name (e.g. quality,
content or whatever is in the raters mind).

If one would generalise all tags to 2D, normal tags have a lower bound
of 0 and an upper bound of 1 (i.e. binary as today), and star ratings
have a lower bound of 0 and upper of 5. If tags had customistable lower
and upper bounds, with a default of being binary, any tag could be set
as with a custom span, and 2D, 3D or any other -D sets could be flexibly
selected.

E.g. a photo of my garden could be tagged "nature 2/5", while the shot
from the amazons is tagged "nature 5/5"; a picture of a car in the
street may be rated "cars 1/3" while that of an F1 car in the pit stop
"cars 3/3" (as an example of flexible use only, not to be seen as a
suggestion!).

That would be great for generalisation, however the only use I can see
personally is to differentiate quality and content rating, so two linear
tags (star ratings) would suffice.

Hello everyone,
Please, when implementing these ideas keep in mind that our photos don't stay just in our digikam libraries, but sometimes they go also in Lightroom and Aperture (...)  libraries, since there is people (like me) working with other people or with different OSes...

I'd really like that any metadata I added to a set of shots using Digikam will ben visible also with other software, so we don't marginalize ourselves.
At the moment the situation is really nice: at least on a friend's of mine Aperture (didn't try other software) you can see every information you added using digikam, and it's cool.
Please, keep in mind this need, and don't implement too incompatible metadata...

regards
gerlos

Sure, this is a priority.

But we need to know where these softwares store these information.
Typicially it's in XMP namespace, but where and which encoding ?

As i have Aperture installed on my macbook, i can check it for Apple,
but i cannot test with all photo management softwares.

it's a good help for digiKam team if users can send images with right
tags set in metadata, to check import into digiKam.

For the export (digiKam to another software), it's another story. But
in all case, we have now a clean implementation which is easy to
adjust for all case...
