    I got a lot of truble with the contrast issue. Today I was with very dramatic weather taking some pictuers.

    Please could you give me feedback if there are acceptable (with contrast) and also with other issue.

    First two don't have issues with contrast; the third I would consider borderline.

    Mostly correct, although the histogram can often (but not always) give a good indication of what will be acceptable.

    There is strong enough light on the aircraft that I don't think contrast would be too much of an issue, although there are other problems present.

    thanks for the explanation. (also for removing the links, I won't blame someone at all or point out).
    I think I understand now a bit more, but It's still difficult to judge.

    Is that more or less the point?

    Usually, but not always. Certainly images taken in overcast conditions will be more challenging to get accepted.

But why is the contrast in those two pictures fine? there is no tool to judge the contrast, it's a visual decision? I really like to understand because the most rejection are due to contrast.

    I've removed the links, since it's considered bad form to bring up the work of others who are not directly involved in the discussion. Yes, both of those are somewhat lacking in contrast, but if you had checked a little further, you would have noticed both were first images of those particular regs., for which we are a little more lenient.

    thanks for the reply.

    But I don't get the point of 'Too much or too little contrast.'
    It mean's the sky is too dark?

    Is there any further information on the forum? What do I have to pay attention? What do I have to do to get the needed contrast?

    I really like to understand what screeners are looking at and what they judge for the contrast issue.

    Thanks again for mor help and informations.
    It means there is a lack of clear contrast between parts of the image. Usually this is due to flat/overcast light (as in your image), but yes, could be due to washed out/bright sky, or other things. Sometimes it is easily fixable, but in this case, due to the poor light conditions I mentioned before, it would be much more challenging, if at all possible.

    As you can tell by the unbalanced histogram, the light is very flat. Under/overexposure has nothing to do with it. The flat light is caused by the overcast conditions, and will be very difficult to fix with editing.

    What do I have to adjust for 'undersharpen (soft)' as rejection reason. I have no idea what to improve. Is there a description? What does it mean actually? Not sharp? To less contrast?

    The picture are for example here:

    Thanks a lot for advice.

    Hoi.

    "Undersharpened-Soft" does indeed mean that the image is not sharp.
    So you have to sharpen the images to make them acceptable.
    #1 can be acceptable with a better edit
    #2 blurry tail and soft lettering in the front - this can not be fixed to be honest
    #3 same as #1 - probably acceptable with a better edit. Make sure to copy the dust spot below the engine out, otherwise that can lead to an rejection too.

    Have a good day!
