I scanned quickly for what OS you are running but did not find it; I
run openSUSE 13.1<br>
dK 4.0.0 arrived a few days ago, with all the fixes Gilles reported
that enable multicore.<br>
<br>
Local Contrast and Sharpness tools now blazing fast(by comparison)<br>

I finally had time to locate some of the lousy original photos
I had successfully improved with a couple of other programs,
including, oddly, that Nokia (Windows Phone) Fix. <br>
<br>
Putzed with dK Local Contrast, works beautifully. Just what I
was after. <br>
<br>
I tried to find information and help in the dK PDF, but could
not. Searching online, "local contrast" brings up a lot of
Photoslop entries, but they necessitate using layers and
unsharp mask. So much for the expensive program. If I add
"digikam" to the search, I just keep getting repeats from a
blog posting.<br>
<br>
I'd like to learn how to manually control adjustments for best
results.<br>
<br>
Any further help to be found?<br>
<br>
Oh, yes. Kind of slow, but if I factor in the need to open
another program, rename, shuffle files, Local Contrast is
another dK winner!<br>
<br>
Thanks, Giles (and all others!)<br>

<pre wrap="">digiKam has LocalContrast tool which make the same correction to
image. In fact it emulate pseudo HDR rendering.

<pre wrap="">Background: I've been in digital photography since 2000, decades of film
before and since. I'm certainly familiar with the use of curves to correct
bad photos. But so tedious, and if the photos are snapshots, hard to
justify the time. It appears to me, although I can't prove it, that digital
cameras, discrete or within phones, seem to be doing a much better job
automatically adjusting curves than my old Minolta A2, for instance.
I recently became aware of a new free Canon program, My Image Garden, that
has a much improved Auto-fix than its forerunner. As an example, a backlit
photo processed in MIG will bring up only the shadows while leaving the
normal and highlights alone. It allegedly uses a zone by zone analysis. It
is a terrible program in every other regard, clunky interface, bloated, etc.
But I used it for some recent pics to advantage.
Some of those pictures were originally on my Windows Phone 8, which I had
copied to the HD. Before I deleted them from the phone, I poked around with
the options at that point. I found an auto-fix, pushed the "button," and my
jaw dropped. Literally. A very dark, underexposed shot made perfect! This
feature is within the Nokia programs! It is so good, I can see myself
transferring photos from other sources into the phone for correction! And
it's fast, even so.
I went back through the digiKam manual and looked on screen, and I see the
old standbys there, but nothing like what I've experienced with the above.
Oh, upon lots of research, I found a 2007 $40 program called Photoright that
upon test, seems to be doing similar zone adjustments.
Bottom lines: Are my observations valid? Do you think DK might get
something like this? Oh, yes, all Windows although MIG is available for
Mac.
Thanks, Paul Verizzo
