Heat haze, Blurry, Oversharpened??

Just received these 3 reject reasons on this photo. I personally think if this photo can be considered as a blurry and heat haze image, then I believe there are so many accepted pictures have these problems. Also I didn't adjust the sharpness so the sharpness comes directly from the camera, which I don't think it is oversharp. What do you guys think?

It does look blurry and oversharp to compensate in places. Not sure where heat-haze comes into it, though — I know this spot very well and, although the APUs of parked aircraft can be a pain, the effects are immediately recognisable. No heat haze here. Moot point, however, considering the other reasons.

Of course, in some occasions people might increase sharpness in order to reduce the blurry effect, but clearly not this one. As I said, I didn't do anything related to sharpness since the original version looks solid enough.

Furthermore, I can give you an example that really represents Blurry and sadly the photo was accepted.

Danny,

To be fair, you appealed the image earlier today and it was not tagged for heat haze when rejected by the head screeners. Therefore the only issues in question remain the blurry/oversharpened which I support. The window line is blurry and as are the titles with oversharpening evident. There is a haziness by the titles which I'm sure is what drew the initial heat haze rejection.

Hope this helps.

Thank you for your reply

However, I disagree with your conclusion, the light condition in this image is slightly weaker so windows are having some reflection and the outline of the window cannot be compare to those photos in perfect light condition. But this cannot be called blurry because the window part still on focus and solid. I also disagree with the oversharpened rejection since the sharpness of the photo comes directly from the camera. if the origin version of your photo already have enough sharpness, then I couldn't see any reason to adjust this part because the version that comes from the camera usually would be the most natural version. Also, I couldn't see any reason to reduce the sharpness which might cause it soft and blurry.

There is an accepted photo example which I think it is a perfect example of blurry.

I believe the problem with this photo is more serious than mine since many details in this photo looks terribly blurry and the edge of those windows has been deformed due to the heavy heat haze!

I am very disappointed with the screening system because you guys sometimes just let those terrible photos pass the screening but very picky on those decent photos.

I'd agree that the LOT image is questionable but that doesn't detract from the fact that your ANA image is relatively poor, especially considering how many superior shots of the same subject are in the database.

I always say this but it never gains much traction: link the full size original file and we'll be able to see if it's blurry right away. Full res images are unambiguous and flaws are pretty easy to spot.

Rejections happens - it is a part of the game and the proces depends on humans who view things slightly different. The advise Karl has given about linking to the full size original file would be a great option to clear this matter.

The photo does look blurry/ oversharp.
