This is a case where the BW definitely emphasizes the blown highlights. Overall, excellent conversion.

Hi, Cal.

Are you sure that your monitor is adjusted properly? I don't see any blown highlights at all in this photo.

I copied the mailbox image to my PC and loaded it into Paint Shop Pro. Unsurprisingly, all the obviously white patches. e.g., the path at the left & the tops of the mailboxes show RGB of 255, 255, 255, using the eyedropper tool.They're blown.

By contrast, over on the right, the white louvres and their surrounds, and parts of the wall do show tone, and they have lower RGB figures.

I did this because I've just changed my monitor for a flat screen LCD one. I got fed up of thumping the old VDU every half hour when it went blue. My only criticism ofthe new one is that the brightness depends on my degree of slump in my chair. I'm therefore worried I'm not seeing what everyone else sees.

I've adjusted it using test charts with step wedges and dozens of colour shades, so that it agrees with my printer when I'm looking straight at the middle.

Yes, butthe colour version is better. The blown highlights on the mailboxes might well have been what the eye could have seen at the time, and seem quite realisticin both versions, but the path has got blown in the conversion.

The path/steps on the left have some shades of tone in colourand not in the monochrome. This is just the sort of issue that's defeated me throughout this challenge in most of my (mercifully unposted) attempts. I kept hitting the same problem and usually gave up.

Hi ho, Alan T
