I would be interested in help ensuring my monitors are properly calibrated. I viewed my last entry on my two Dell 1900FP monitors (both running on the same CPU and a a cruddy ATI Fire GL card, one on analog the other digital), and I didn't see any dust, nor could I see any sheen or details on my backdrop. However, the other day I looked at it on my laptop, and the backdrop sheen and lots of dust were visible. Perhaps this is why it did much worse than I expected. (I didn't fix the dust, even though it was allowed, because I didn't see it!)

Using Adobe Gamma, I have to set the Gamma completely wrong in order to see much more than a fleck or two of dust on the background. I'd be grateful if anyone running the 1900FP could send me your profile. Also, let me know--what do you see, a couple of flecks, or a sea of dust? Can you see the sheen on the black velvet backdrop? (I cannot without abusing the gamma)

Also welcome tips on getting that dust off of my velvet!

Thanks in advance.

Neil,
I can see a few dust specks as well as just a hint of the sheen on the backdrop. This is on my Sont Trinitron CRT, which is reasonably well calibrated.
Interestingly I had the same experience with my "black" entry. I edited it on my main system, and first time I looked at it on my laptop I almost died; it was much grayer on that screen.
My guess is that your Dell monitors are closer to correct than your laptop, just like mine. I really need to go thru gamma settings again on my laptop...

I can see the dust but hardly detracts from the awsome image, well done!

The top is completed black but where the velvet is placed I can see the whole velvet with a lot of dust.

I can see a lot of brush strokes used outside the circle. The camera inside the circle looks a bit gray and looks like a bad composite from a b-movie ;)

Viewing with a Sony Trinitron CRT multiscan 210GS. Recalibrated before viewing the Black challenge and noticed a lot of my older shots suck.

Thanks faidoi. I suspected that others were seeing these exact defects and I think they certainly affected my score. I'm going to re-run my monitor calibration. Do you use hardware calibration, or just software?

Adobe Gamma. Plan on doing it at least every month.

Fritz, on yours I see the foreground texture (almost like a tericloth), but I don't see anything but black outside the circle as reported by Faidoi above. EXCEPT on my laptop. Then I see what Faidoi is talking about. Faidoi, are you sure your monitor is calibrated correctly? I just ran Adobe gamma on it and now both Kirbic's and my photo are more like my desktop.

In any case, it's something for us to watch for, given the different way monitors can be set and how revealing it can be!

Thanks Neil,
I just quickly ran Adobe gamma again, I made a very slight correction, not enough to even notice a difference. I'm calibrated to gamma of 2.2 and 6500K color temperature.
Given my "black" debacle, I will definitely be taking more time on backgrounds that I *think* should be invisible!
Reminds me, I wanted to post another question on my "black" shot; off to post...

When voting on a challenge how does the b&w bar below looking on your monitors? Total separated boxes of colors or smooth graduation?

Lighting near the monitor and how long the monitor has been on will effect the settings correct? Will try recalibrate with sunlight to see if there's a difference tomorrow.

I have turned my LCDs up all the way, they are bright and blinding, but I can't make out differences between the last 4 or 5 black squares unless I set the gamma incorrectly. Can you?
