Smile Sharpening help

http://www.railpictures.net/viewreje...41&key=3949384

This was rejected for being under sharpened. I have spent a fair amount of time trying to improve the "sharpness" of the image with no real luck. Sharpening is a real art. The image does not look particularly unsharp to me, the original file seems acceptably sharp, although it is not one of those images where the sharpness jumps out at you. The engines look okay to me, but the bulkhead flats do look a bit strange. I think it is the lighting more than anything. So I'm looking for opinions and help. This is not a great picture but I though it might be a useful learning experience.

Thanks in advance.

John

If you sharpen those flats more, they will go more wacky. Do some selective sharpening, maybe in this case selecting most of the frame but not the loads, and see how that goes.

It is sharp enough for me too. Sometimes RP likes them crispy.

Thanks Januz. Since posting I went back and played with the original large tif file. First I looked at it at the actual pixels level. Pretty sharp. The problem with the flatcar loads is simply the lumber mill logos make them "busy". Then I sharpened it until those little zigzags started showing up, and then backed off. Then I went through the process of converting to a jpg and resharpened. Then I compared it with the version I submitted. I cannot see any difference. If anything I like the older version better. Like you said, maybe the folks at RP like extra crispy....which is fine when you have lots of contrast to work with. The light does not always cooperate. And since it is a pretty basic wedgie, the bar is high. But how many pix of the CB&SNS do they have? Especially with the sun out. C'est la vie.

Took a shot at sharpening just the frame. I can't really tell the difference, but maybe it is better. One of the fascinating things about all this, and its kinda like tasting fine wine, some folks see or taste differences that I'm just totally oblivious to.

That's a nice shot of some classic power. Looks great to my old eyes and on my laptop. I guess you must need a reference quality monitor to see the difference. Do the screeners use a CRT monitor for screening images? Just curious.
