Nice burnt highlights. Glad to see that histogram is doing well for you.

Not the site, but that particular server, so I've replaced the image:

If you saw what DSLR images Roger posts to his site you would say "nice
burnt shadows".

Thanks for reposting, John.

All the detail in the foliage at the back is lost - possibly due to the
noise reduction.  Nice photo, though.

Cheers,
David

It is a nice *scene*, but as David notes, the foliage has lost a large
amount of detail, and as Mr Strat notes, the highlights are a touch
over (although that isn't a big deal)..

It is not a technically good image - even at the reduced size, the
foliage is clearly (heh!) mush, and detail is completely obliterated
in the darker areas (ie almost all of the background).  A large print
of that image would not be a good idea.  Yet a DSLR, competently
handled, would have sailed through this test with flying colours.  Pun
intended..

That type of low-contrast fine detail is a indeed a tough test for
digitals - especially small sensored ones - and this one has failed
the test.

To get better results, you could use a better camera (O:, but if that
isn't an option:

- shoot in RAW.  That way you do not lose any more detail to jpeg
compression or noise reduction (depending on the camera), and also you
will improve the dynamic range - this scene clearly needs all the
dynamic range it can get.

- watch your post-proc very carefully.  *Selective* noise reduction
can help (ie *don't* apply NR to foliage areas!), and also watch any
gamma/brightness/contrast adjustments - working in 16-bit, at least
initially, may also help.

Just trying to help...  In a couple of years time, assuming you get
good at this imaging stuff, come back and re-visit this image...  At
the moment I think you may be a little emotionally attached.  (O:*

(* I'm allowed to be unkind if I put a smiley there - John said.)

And just to show I'm not *all* mouth... here's an example of an image
with a similarly wide (probably wider) contrast range, shot on a
similar (but, imo, better) prosumer
:
http://www.marktphoto.com/examples/pano2_small.jpg

(Note -it's a *large* panoramic image - 1.4Mb jpg...)

It was shot in RAW, and I (crudely!) used selective noise reduction.
Note the foliage detail in the dark areas compared to John's.  Yes,
it's somewhat *noisy* detail, but it's .. *there*.

I am very happy to post a full-resolution crop if anyone wants one.

Thank you.

What this actually shows is the limitation of 8-bit JPEG on the very
wide luminance range reducing luminance resolution in shadows, limited
depth of field from the wide aperture I used to focus on just the
fountain, additional JPEG compression for hosting, and the effect of
direct sun on the lens (flare).

The image might have been a little better technically if I had used RAW
instead of JPEG Fine, but that would be due to the greater luminosity
resolution of RAW as compared to 8-bit JPEG and reduced loss of detail
from JPEG compression, not noise reduction processing (which was turned
down to Low). JPEG Fine did quite well nonetheless.

Totally different image, and too shrunk to make any real assessment
possible.  Don't you have anything else?

No, it's a crap photograph of a nice scene.  It would be ok if better
composed, and if it didn't have total MUSH for a background.  The fact
you can't see the mush, speaks volumes.

No, of course not, dear.  Two people comment on it, but you are of
course a better judge, seeing it's your image, and you're not like
'biased' or nuthin.

What a great comeback - you should use it more often....

What a pile of unadulterated crap.  Anyone with more than a couple of
weeks of post-proc experience will easily be able to avoid the
overcontrasty look and the lost highlights and shadows *provisding the
oiriginal is up to it.  If it isn't, you only have yourself and the
camera to blame.  The only other person who makes this sort of claim
about using 8-bit JPG's is Douglas MacDonald.  You're in good company
there.

And I love the HYPOCRISY - elsewhere you are talking about the need to
post a 7Mb jpg image to keep the quality up, but here, the hosting
compression is at fault.  Hahah!!

Oh.  That's very clear then.   So you say it *was* you and the camera
at fault.  Glad we sorted that, finally.  Er, except it wasn't...  (O:

More malware and popups?  No thanks.  Get a clue about image hosting.

Wow!

How did you get the background to look so ... muddy?

I can't reproduce that 'look'...
