    Did I over do the contrast with this image? Or does it need more?
    I'm puzzled with this one.



    (I still would prefer the rejection reason to be changed to either too much or too little instead of both).

      There's no reason at all to be puzzled by this because as with previous examples, a look at the histogram tells all.



      Looking at the photo I immediately see slightly light shadows and slightly bright highlights which is precisely what the histogram is showing, so overall the photo is a little bright but it should be correctable editing again from the original. I'm really not joking when I say the key to understanding contrast rejections is understanding the histogram, and learning to read it properly will mean you'll perfectly understand probably 99% of contrast rejections you'll ever get. Most of the information you'll ever really need to understand contrast rejections in written right here in this thread.

      The photo's also quite soft, so again try to look for all possible flaws when you edit and try not to concentrate on just a few.

          Hi Sergi,

          Paul his guide has helped me to overcome this issue you are having (I still get a contrast rejection now and than, but when I do, I see why and am able to fix it (in most cases)).
          Work through this extensive guide a couple of times until you get it.
          Play with the settings to see what happens.

          About your images:

          I assume you are using Photoshop?
          If you open your images there, try the following:

          Open Image |Adjustments | Levels (or press CRTL-L)

          Move the slider in the center to the left until it reads 1,30 (for the A380) and 1,40 (for the A319).
          They will look much brighter (and better), they are now both too dark in my opinion. You may want to try different settings to see what happens.
          Hope this will help you understand these rejections.

            Nice idea!
            Hope this helped, I upload images after correction with levels as you suggested (Photoshop CS3):






            And i correction photo of Croatia (Star Alliance):


            I hope that the photos are better now, what do you think?

              Siegi,
              They look MUCH better now. Can you see the photos look more natural?
              I think they would be probably be ok now. However I will have a proper look later.

                  Much better indeed! Although I feel that the A380 is still a 'tiny bit' too dark. But I'm not a screener.
                  If you want to have a better indication, post your images (before uploading!) in this thread: http://forums.jetphotos.net/showthre...302#post559302

                    Also, please do not upload your photos to the queue to show them here for pre-screening. Upload them to any other photo space, like flickr or imageshack.

                      Thanks anyway LX-A343, but meantime I'll leave the photos queue to JP, it seems if they accept photos and if not then fix again.
                      I do not feel that the A380 a little dark.

                      Regards,

                        The Lufty A319 looks fine but the other two are quite overexposed. My tutorial Ryan linked to places very high importance on using the histogram and doing so will avoid these problems by telling you as soon as you start to blow pixels. The histogram is your friend, so make good use of it.

                          Overexposure? the pictures is no burnt, if too high exposure photos burnt.

                            The histogram really quite strongly disagrees:



                            The line going up the right side of the graph is showing you that parts of the photo are overexposed, the peaks on the left are also showing the shadows are a little too strong. The histogram really is the digital photographers' best friend.

                            Your colour space is also wrong. It's Adobe RGB, which means in certain browsers your images will be viewed with less saturation and contrast than your originals. It should be sRGB for internet use.

                              I understand, thank you, i'm a little worry that the bottom plane (wheels) has a shadow also bottom of the engine shaded.
                              Try as it seems pictures in queue and further on the, each sees a different picture in his opinion.
