Check this shot and a 100% crop of the top of the sail.

Now that's better.

... and that's interesting ... umm.

...and what exactly did you find interesting?
I was thinking that the edges look slightly fuzzy and the contrast is
soft. Here by way of comparison is a photograph I took some years ago
when I first got my D300
https://www.dropbox.com/s/usuksr9zjd...C1038.jpg?dl=0
and here is a 100% crop of the same image.

Now I am somewhat baffled that you find my windsurfer shot above in anyway
comparable to your postage stamp size kite shot.

Postage stamp?

I was refering to the kite, which is less than postage stamp size regardless
of your crop.

I misunderstood you. I thought you were referring to the image as a
whole.

The microscopic kite was lost in that sea of blue.

I picked the kite image as as a convenient example, as the string was
a single sharply delineated object so narrow that any blurring of the
edges would be immediately visible. I included the full image only to
show where 100% crop came from. The point I was trying to make was
that the unprocessed kite image seemed to be sharper than top of the
sail in your image.

....er, OK.

That is an artifact of Dropbox.

I don’t seem to get DB artifacts which shrink kites. Strangely enough I
don’t get any DB introduced artifacts of any type.

You should be able to down load the file.

Yup!

When I do that I get a full height image. On my screen the 100% shot is
180 x 165.

Strange? Your original downloads as a 6MB, 2848x4288 @ 300dpi, jpg.
Your 100% crop downloads from DB as a 656KB, 1056x1152 @ 300 dpi jpg.

ISO200, f/11, 1/400, 16-85mm



Here is a different example from the same shoot, with a 100% crop.

That is sharper. There is a fuzzy edge to part of the sail but I suspect
that has been caused by highspeed flutter.

...and if it is a kite shot you need, there were kite surfers there, so
here is one which can provide a more meaningful comparison with a 100% crop.

I picked the kite photo because the way the camera was able to resolve
the full length of what was not a particularly large cord, which was
probably less than 1/3 of the diameter of the cords used by the kite
surfers in your shot.

...and that makes for a nice abstractish line in the sky.

At the time I was most interested in the curve in the line caused by
the wind shear.

....and a pleasing curve it was.


No processing has been done other than converting from NEF to JPG.

Would it have mattered, given that the original target was so small?

I can't understand your comment about that, particularly because
Dropbox seems to have removed the EXIF data.

Nope! All the EXIF data was complete DB removed nothing. Here is what I got
after downloading your 100% crop.

https://www.dropbox.com/s/vui0lq9vhhjghr0/screenshot_338.jpg?

Here is what I got when I tried to access the EXIF of the Dropbox
image using Firefox.
https://www.dropbox.com/s/cy1csuvrm2s8k8k/Kite.jpg?dl=0
Normally I get the full EXIF.

Interesting. That must be a Firefox/Mozilla thing DB has removed nothing, and
even you have been able to get full EXIF at some time or another. I had no
problem using Safari on my Mac.

Just for the Hell of it I also checked the full EXIF
usinghttp://exif.regex.info/exif.cgi and it seems that processed, or not
your image shows a definging correction applied:
Defringe Purple Hue Lo: 30
Defringe Purple Hue Hi: 70
Defringe Green Hue Lo: 40
Defringe Green Hue Hi: 40

Then I guess there was sharpening applied in-camera to show:
Sharpen Radius: +1.0
Sharpen Detail: 25
Sharpen Edge Masking: 0
Sharpness: 40

Color Noise Reduction: 25


I considered your target to be the kite, and that was resolved so small in
both the original, and the 100% crop that determining sharpness of that kite
image to be near impossible. Therefore my thought that no amount of post
processing would have made a difference.

And still it was sharp.

The line was sharp, the kite was something less than sharp.
