One of the comments on my Free Study entry speaks of 'very noticeable editing problems - haloes everywhere'. I'm a bit confused because the only editing done to this was rotating and cropping and possibly slight use of unsharp mask. And I really can't see the haloes he refers to. I have never had any reason to believe there is a problem with the calibration of my monitor, so I was just wondering who's right here? Can you see the haloes?

My monitor is calibrated, and I can barely make out the smallest of halos on part of the underside of the larger crane. Other than that, I don't see anything....

Maybe the commentor is thinking that the sky rings are halos possibly? I dunno I guess, looks pretty nice to me actually.

There are some very slight halos on the crane and the top of the building. Looking at it at 200% magnification they are just visible on my CRT, and I'd imagine they are somewhat visible on an LCD at 100%.
One issue on the user end is that some LCD monitors have a "sharpness" setting (my wife's does) that at default setting can really make things look oversharp.
Depending on the resizing algorithm used, and the USM settings, you may have introduced the halos. Sometimes what people see as halos are really bright edges of objects; I don't think that's the case here though. Do you recall what radius and amount you used for the USM, and when you applied it? Was the image shot in RAW or JPEG? If JPEG, what is the in-camera sharpness setting?

The key word here is "one"... I think that person might have some strange adjustment on their own monitor or possibly been smoking mind altering substances... no offence intended. :)

Forget about the halo comment. Your low score had more to do with less interesting composition and lack of 'wow' factor more than anything else.

Heh, I sure do agree that the score was not in any large part affected by the presence of the extremely mild halos. I do think, though, that a sharper-appearing final result with no visible halos might be possible here, depending on the original.

I rest my case and I know this is early to do such a thing, but I nominate kirbic as "Mr. Diplomacy, 2007". ;)

Thanks. I wasn't actually questioning the score. It was that one comment that bothered me.

I don't remember my USM settings (if I used them) but they were no more than usual. As for the camera, it only shoots JPEG and there's not that much control over settings. I always have them the same though, and nobody has said anything like this before. Seems like it's a bit of a storm in a teacup anyway if the haloes are only just visible at 200%.

Eloquently stated.

Something really strange is going on here. I just reopened the image to see whether I could see any minor problem, only to be presented with an image with the most awful banding I've ever seen. I closed it and tried again and it's back to normal. This has never happened to me before (not with one of my own images anyway and I wouldn't know with an image I've only seen once). I wonder if something like this could have led to that comment.

On a non pro but calibrated LCD and at 100% are NOT VISIBLE unless u count hat white thingy that looks liek it might be the moon?

Yes, it is the moon. Thanks for the NOT VISIBLE vote.
