Help for correction

Sun Mar 07, 2021 8:41 am

Hi,
This picture was rejected by first screener for : Dark, Low contrast and Underexposed.

https://imgproc.airliners.net/photos/ai ... b1d1b0c9c9

I need your opinions to make some correction.

Thanks

PL

This is a tricky one; I'd agree with the screener but if you increase exposure/brightness, the sky might become too bright and even more color will be lost. The light conditions just weren't in your favor and photo editing won't fix that.

Thank you for your reply. I made the same observation as you and I'm not good enough to correct it on post treatment. Never mind.

Hello Philippe,

The image is underexposed.

I took a look at the image in Photoshop. If you drag the right end of the histogram over from the current 255 to about 230 it should brighten up the aircraft without blowing out the sky. As a matter of fact, I selected the "auto contrast" function and it did a nice adjustment as well.

Regards,

Jehan

Wouldn't this chiefly brighten up the sky rather than the a/c itself?

I tried what I described n Photoshop Elements and it seemed to work.

So did I and to me it seemed that the increase in exposure for the sky is larger than for the aircraft. Because, if I'm not mistaken, with the right slider you just brighten up the lighter parts of the image (in this case the sky) rathern than the darker/shadowed parts (in this case most of the aircraft). Therefore I'm not sure it is an actual improvement but it might be worth a shot :).
