well it all depends on the orignal pic, if this was shot RAW then definitely it should be possible. That's a basic case of underexposure of dark tones and your question makes me really think you need to read a bit more about how to read the histogram. Once you manage to learn how to read it and its information then you would make a huge step forward to avoid contrast rejection.
For the Dash8 here above, the issue is actually to upload it. Such picture in such light conditions will never be acceptable for JP, light is just too bad and by selecting which picture you upload or not you could greatly improve your acceptance ratio as wqell.
Cheers

Hi Alex
ok, this probably could not be corrected in PP, or at least I would not know how to do it.

Hi,
See the left part of histogram, it shows a very important underexposure of dark tones.
Regards
Alex

Oh yes. it was only to reiterate that the problem of too much ..... remains a mystery almost irresolvable to me

Feel free to message me if you would like me to edit a photo.

ok tnks Brian.
Yes I use photoshop CC 2018 but I think the steps are the same. I will try to apply this method as soon as I understand it well.

In Photoshop CS, when you are adjusting the histogram for brightness and contrast (and you will often see a comment in the forum or in a rejection to "check and adjust the luminosity histogram" when you get a Dark/Under and/or Contrast rejection, especially from me) then you should be using the luminosity histogram rather than the default RGB histogram that you see when you go to Image....Adjustments....Levels .
......................................
The luminosity histogram can be found in "Window....Histogram". Select this option and park it in a corner of the screen. Click the middle tab named Histogram and using the drop down find and select Luminosity.
You cannot work directly on this histogram.....
...so now you need to go to "Image....Adjustments....Levels" where you can make adjustments. Make sure that you have RGB selected here. You will see three arrows on the baseline of the graph. The left side arrow adjusts the dark tones, the middle arrow adjusts the midtones and the right arrow adjusts the highlights.
You might also see that the two graphs are a different shape and may well have different gaps at each end. These gaps indicate missing dark and light tones depending on which end of the graph they are at. You need to drag the relevant arrow in to touch the graph where it meets the baseline. Make the adjustments on the RGB graph but watch the effect on the Luminosity graph. Setting the left and right side of the luminosity histogram will set optimum contrast. You may have to adjust the midtones as well especially if you have deep shadows or bright highlights but this is a personal judgement for you to make.
So, remember, when you process use the Luminosity Histogram to set optimum brightness and contrast.Last edited by brianw999; 2018-11-15, 10:00.

Even the histogram is not always helpful. Say in the pic you have some green bush very close to you and then the plane much further away and in the fog. If you are cose enough to the bush, your histogram can still be fine, while the plane is still in the fog.
