Sharpening
Posted: Sat Oct 07, 2006 10:06 pm
Hi - I have been having a bit of a problem with a new nikkor, or maybe it is with the D200
I noticed the new lens was not producing sharp images. I mean sharp when you zoomed in playback on the D200 and not sharp on screen when downloaded.
Then I noticed in Preview on the Mac that, if I applied the sharpening slider to the mid-point, what I thought were pretty ordinary eyes on my subjects became as sharp as diamonds! The same thing happened in Nikon's Picture Project and in iPhoto, and in Adobe Lightroom - yeah, I've been checking around!
Is this normal? the D200 was set to normal sharpening. I banged it up to max sharpening, but the results were much the same - the best, the sharpest images were produced on the computer screen by moving the sharpening slider.
True, when the sharpening is applied, the images really pop. Having noticed this (I am quite a novice at digital photography) I went back and checked what I had thought were sharp images taken on the D200 with a 35mm f2 and a 70-210 f4.
Lo and behold they responded the same way - became really sharp! so I am now wondering about my lenses and the whole digital thing.
Another unusual thing has happened. When I save a sharpened image in some of these programs - it reverts to an unsharpened state! even with a different file name. And it does not appear, when uploaded to a web site or sent as an email attachment, to be as sharp as when I sharpened it on screen. What gives?
has anyone else been down this path?
many thanks
Dan
