    Thank you dlowwa.
    Yes, it doesn't come as a surprise, but I was not able to see this problem in many other photos. But this is MY fault, of course

    Meanwhile, I was trying some intervention on the photos, opening the 1200px jpeg with ACR (using Bridge) and adjusting white balance.
    Do you think I'm addressing the problem properly?

    Thank you very much, and I hope this post doesn't infringe the 24h rule, since I was not asking for a pre-screening in the previous one

    I got a bunch of rejections for the photos I uploaded recently. I got rejection for the photos I was more confident about (!) and for which I did not ask for a pre-screening.
    All the rejections are for Bad Color (Over/Under Saturation, Hue) which evidently is the cliff I'm not able to address in my workflow.

    Some of the rejected photos are these (please note that I'm not asking for a pre-screening, since they have already been rejected in this version):
    [ATTACH=CONFIG]27612[/ATTACH] [ATTACH=CONFIG]27613[/ATTACH] [ATTACH=CONFIG]27614[/ATTACH]

    For this photo, I also received the comment "yellow too strong":
    [ATTACH=CONFIG]27615[/ATTACH] [ATTACH=CONFIG]27616[/ATTACH]

    I am really not able to point out and set the correct hue. I'm not using LR for aviation photos and I could surely use it to balance whites, but first of all I need to be able to see which color is wrong, and evidently this is not my case. In some of these photos I can recognize the whites have a shade of color in it (but often I'm not really able to tell of which color), while others look white to me (e.g. EI-DEC).

    Could you please point out to some forum discussion or tutorial in which it is explained how to deal with hue problems? I found this: https://forums.jetphotos.com/showthr...-contrast-help but is this the way? In the above histogram, should I have applied some modifications to the white balance in order to shift left the red bar on the right, and this would have corrected the yellow cast?

    If this is the way, is there a regulation that can be used directly in PS and not in ACR or LR?

    Thank you in advance.

    Thank you, dlowwa! I have gone through the whole batch of photos I took yesterday to get rid of the remaining dirt, which I did not see with my checking tool (Filter -> Adjustments -> Equalize in PS6) but that was visible with the jetphotos upload tool. I have fixed the problems (hopefully) and put #3 in my private collection.

    If you don't mind, I have some other, specific doubts for some of the photos I took yesterday:

    [ATTACH=CONFIG]27295[/ATTACH] [ATTACH=CONFIG]27296[/ATTACH] [ATTACH=CONFIG]27297[/ATTACH] [ATTACH=CONFIG]27298[/ATTACH] [ATTACH=CONFIG]27299[/ATTACH]

    1. I have left more empty space than usual to include the whole easyjet and the whole tower in the background. Is this crop acceptable?
    2. Is heat haze acceptable here?
    3. Is contrast ok?
    4. Is contrast ok?
    5. There is a straight line in the sky just above the fuselage, parallel to it, which at a first glance seemed a halo to me when I checked the result, but it is there also in the original file... Should I get rid of it like dust spots, or is it a product of the airplane vs. the air, and so a normal occurence?

    Thank you very very much for your help.
    1. borderline heat haze. centering ok.
    2. borderline heat haze/overprocessed (editing halos)
    3. borderline color (yellow)
    4. color
    5. borderline color. looks like cloud above fuselage, so should be fine.

    Hi Sergio,

    I'm not a screener, but this is just an assumption on what the screeners will possibly point out.

    1. Noisy, underexposed, slight CCW rotation, oversharpened.
    2. Oversharpened, borderline noise, contrast, just a touch more exposure.
    3. Heat Haze, Contrast, tiny bit of CCW rotation
    4. Contrast, overcast type of shot, can't get away from a rejection on that..
    5. Slight touch more exposure, but looks acceptable to me.

    Like I mentioned above, I'm not a screener, this is just what I see. It can be different from what the screener points out.

    The indoor photos have cut highlights in the histogram, but it is due to the light from outside in the windows. Is this a problem?

    1 & 4. borderline contrast/overexposed
    2. soft
    3. motive (identifiable faces)
    5. soft, centering

    The 330, borderline backlit and needs a 0.2 CW rotation.
    737, light looks ok but I would crop it a bit tighter, there's a bit too much empty space in front and back of the plane
    The helicopter looks ok
    The ramp shot has a very dull light and most of the frame is empty so motive wise it wouldn't be accepted.

    Hope it helps
    Alex
    It helps a lot, as usual. Thanks!

    This category is to be selected for old planes (anything that was not built after 1970, or where the production started before 1970), planes that are no longer in regular service and planes in museums. Also, replicas of vintage aircraft need the "vintage" category.
    Thank you Alex. Damn, while checking the guidelines I saw "warbird" and missed "vintage"

    Btw, may I still ask an opinion about this batch? Thank you!

    In your opinion, is the next photo acceptable and which category should I select? (It's Shanghai Pudong before dawn, I thought to upload it as ramp):
