Post screening

Hi!
Reject - Underexposed
https://imgproc.airliners.net/photos/ai ... 99d18e7469

Underexposed - in my understanding is a dark photo. But I don't understand the dark / normal criterion. This photo was taken at dusk and the live "picture" in eyes was much darker. I usually focused on the histogram but it doesn’t work here, the photos are already unnaturally lightened, in light colors there are already losses. How to determine when the photo underexposed, and when normal?

Thanks!

There is room for improvement on the right side of the histogram.

Could use a bit of additional contrast but does not look blurry to me.

There are screeners on this site who see the whole world as blurry.

If you don’t like the site, stop using it. Complaining in forums that aren’t yours is just wrong.

Blurriness varies from screener to screener, monitor to monitor. Screeners are human, and some humans see things differently than other humans.

You don’t like uploading/using this site? Move to another one, no ones going to stop you.

I don't find the fueslage/nose blurry, but not sure of the winglet. Probably a benefit of the doubt for me.

Looks a bit overexposed and a little marginal. Soft tiles. Otherwise passable for me I think.

Thx.
I absolutely agree with "overexposed" but I had to turn up after "underexposed". Sometimes I don't really understand this game. ) There is still some problem of oversharp when reducing the resolution of the image. What is the best way to avoid this?

I find that if you reduce image size in steps it tends to mute the oversharpening. e.g. full size --->1600 pix; 1600 pix --->1200 pix.

Please explain what is "underexposed". This is a constant cause of rejection.
Is it dark? Is it dark in the shadows? Is this a low contrast?
I uploaded such a photo - underexposed
https://imgproc.airliners.net/photos/ai ... 4d40f5d0bc

OK. I thought this was a dark photo, but here it’s heavily lit up with losses in the light, a day was made from the pre-sunset evening, but still "underexposes".

'Underexposed' it s a little misleading as, even with a better exposure, the light is simply against you. One for the personal collection only I feel (perhaps the screener should have put a note to that effect?).

The light falls to the left of the plane, this can be seen by the reflection of light, just a dark livery against a brighter sky. But maybe you're right, sometimes interest disappears to continue.

Runway аligned - reject CCW
https://imgproc.airliners.net/photos/ai ... ad8a211119

Vertical mast aligned - reject CW
https://imgproc.airliners.net/photos/ai ... 32244cc71f

What to focus on when aligning?

What is the "Quality" problem? Is the photo acceptable with this light and contrast condition?

Nothing - it's whatever "feels" level. Same as vertical centering. Which is probably a bit low on both these.

A few of those buildings suggest CCW needed but others are fine — they don't look like the best structures to judge level. I think you definitely overdid it with the second image — perhaps only 0.1 degrees of rotation required.

Seems a bit harsh looking at some images that made it in over the last few days...
