    ah.. great advice . For sure I will, I'm just trying to save your time for (more) important things.
    I've tried to learn a few things to avoid sending all files to pre-screening. But yes, my own screening process, has some (lots of) flaws ...and fails often.
    So understanding the process and having a proof method to verify it is essential.
    Thanks again for your time and help ... and I'll send the next batch for pre-screening
    Honestly, it's no issue checking one or two images once in a while, especially if you are specific about your concerns. It's the guys who constantly post the max 5 images every 24 hours with only comments 'pre-screening please' that start to get on my nerves a bit

    Yes, looking at the two images, I can see and understand "Tint green/cyan" effect.. which looks also less saturated.
    The difficulty to me is to judge that amount or to identify the problem to start with.
    The color balance changes due to time, weather, angle conditions... so sometimes whites are whites, reds are reds but sometimes they have a bit of washed tones..
    .. and that's where probably my problem resides... identify "washed tons/non natural tones" due to brightness/saturation or due to a slight color shift.
    These particularly photos were taken at mid day, plaint o sun shine... < 20ºC , but nonless, no infinity visibility... so I don't known, maybe some color haze/tone wash
    Ok, let's see if I can take more attention to whites... and maybe de-saturate a bit the photos.
    thx again

    Easy way to tell is by looking at the fuselage and/or sky, which both appear off in the original submission. If you have issues with color blindness, this may be much more difficult to detect, but otherwise it's something that should be very easy to resolve by simply adjusting the color balance.

    Is there a (scientific) way to identify : if there's a Tint color issue ?

    Found the problem, is it (usually) recoverable ? are the above fixable ?

    Hi dlowwa, I'm assuming you are back, and enjoyed some great vacations.
    How about these, from a foggy morning ? are they acceptable ?
    Thx for your time and help
    1, 2, 4 very likely contrast rejections; 3 likely dark rejection.

    I realized also that the background/sky isn't the best , to flat for my taste... not enough sparse clouds ... but better dawns will come
    So, here's another try, with the normal out of the camera light.
    Are these closer ?

    PS: Sorry for asking you to review such boring photos.. I'll promise that I won't bore you in the next couple of weeks. Skip my post, have fun , pretend you still are in 1985 ... no wifi in sight

    well.. I'm getting "dark" photos, even on photos that supposed to be dark ... I'm still in the bottom of the learning curve here.
    thx

    How about these two ?

    #1) Trying to align using the fence poles... it would be impossible, because not all of the, are in sync... ( looks like a rolling effect )
    So I choose to align by the tiny roof top, plus the "horizon" of the runway.

    #2) again the poles "aren't in sync" , so I aligned them using the roff top, plus some trees ( the palm tree )

    Horizon should be ok on first one; second has conflicting verticals, but I'd rely more on the structure in the background than the fence, in which case is also looks ok to me.
