Am I over-sharpening?
 

Some shots from the Richmond Hill Winter Carnival, 2006/02/04. No
snow, but it was overcast, and the Panasonic FZ5 is not known as a great
low-light camera. Where it does have an advantage is the 10X optical
zoom lens. The pond shots were taken from quite a distance. I took
quite a few shots, and made a bunch of awful beginner's mistakes. Some
shots came out OK, especially after working on them with Gimp (free
Photoshop-like program). The ones that weren't totally embarressing are
up at...

I tried out "sharpening" on the images. Certainly looks different.
As a beginner, I don't know whether the sharpening is too much. That's
my main question about these shots.

They don't look over-sharpened to me.

If you can see "halos" around objects,
you've over-sharpened -- but I don't
see that here.

To me, the original sized images do look excessively sharpened, for
example:

but if I was viewing on my old CRT monitor rather than my current LCD
monitor (without the focus problems of the CRT), I would probably have
said it was OK.

Too much sharpening will result in appearance of a white 'aura' around
objects. If you don't reach that point, you probably haven't sharpened
too much.

They look just right to me on my LCD but I guess some might judge them as a
little overdone.

I'm using a 19" CRT, and I don't think I'll be switching to LCD soon.
I usually shoot images at 2048x1536 and work on them in that size. I
bin them down to 1024x768 for web display near the end. This cuts down
ISO noise as opposed to shooting at 1024x768.

In linux, you can set up custom modelines to give custom resolutions.
I can push my card+monitor combo to 2128x1702 (YES!). This just barely
holds a 2048x1536 image plus the image window and status bar.

When you can get an LCD at that resolution without taking out a
mortgage, I'll consider an LCD.

They look fine to me.

The photos look ok to me on my CRT monitor.

Well, as you imply large LCD are already here - IBM have a 9.2MP display:

But I wasn't suggesting that you change, as you seem to have inferred,
simply that the LCD will present a sharper picture, and therefore what
might look OK on a CRT could look oversharpened on an LCD.

(On the CRT, the electron beam hitting the screen has a finite size, and
therefore each pixel will be blurred a little. I would expect that when
running your CRT at 2128 x 1720, the individual pixels are not as clearly
resolved as at 1024 x 768, for example.)

I'm looking at them on a 1600 x 1200 21" LCD,
and they look fine to me, sharpening-wise.

The closest thing I can see to a sharpening
artifact is the bass player's left leg in
image #55804450.

Like I say, I've seen far worse.
