why do my plane shots keep getting rejected with "grainy, soft"?

    What am I doing wrong? Every time I upload a plane shot taken in good weather it gets rejected with "soft, grainy". here is a shot:


    [​IMG]

    The original is here (in case something is wrong with that ...)

    This is only one of many examples. So, is it:
    -my camera (Nikon D90)?
    -my lens (18-200 at 120mm with VR, could it be smudged?)
    -autofocus bad (on all of them)?
    -my lousy postprocessing? (gimp, high-pass-filter)

    Out of 20 submitted photos only 2 have been accepted, I'd really like any pointers on what I'm doing wrong, or how I can tell if an image is "soft". it looks fine to me *sigh*

    I assume by rejected, you are talking about stock photography?

    First, I would look at the stock site and post up your question there. Each stock site has different levels and ideas of what is acceptable. Actually, each reviewer has a different level of what they think is acceptable. So the best people to answer why its rejected are those on the stock site (either in a forum or what not).

    Did you look at them at a 100% crop and see if you can see any grainynesss in the sky or some softness in the plane? When you do post up on the stock site, make sure you post the uploaded image AND a 100% crop a section of the image.

    I think I'm seeing some noise in the sky, around the areas where there are clouds and some slight loss of sharpness on the back edges of the plane, along the wings and tail

    I actually mean planespotters.net, a site to upload plane shots. I'm not sure what a stock site is but I'm fairly sure it's something different.

    Yes, the sky (and bits of the plane) look a little grainy. But it's either that or an soft aircraft which is also not good.

    I'd really be interested if the original shot is bad or if I just suck at post processing!

    Could be the post processing. What have you tried doing to it?

    I've tried sharpening it. I've tried several variations of the unsharp mask and he high pass filter. they all end up being sof + grainy. how do you sharpen an image so it doesn't end up too grainy?

    Have you looked at a 100% crop of the image?

    When its loaded in Photoshop or what not, zoom in to 100% and see the level of sharpness / grainyness

    yes, I zoomed into 100% and yes it's grainy

    my question is what can I do about it? because either it's too grainy or too soft.

    is it the bad photo, or am i just crap at sharpening it? what am i doing wrong?

    What ISO are you shooting at?

    A super-zoom lens like that, will not be as good as a pro level zoom or a prime (non zoom) lens. I've heard that the 18-200 Nikon is one of the better lenses in that class...but it's far below the quality of something like the 70-200mm F2.8 VR.
