  • Clone Stamp & Bad Postprocessing

    Hello!
    I've been having a few rejects specially on this "Bad Postprocessing" thing. Kinda annoying sometimes, since my workflow is pretty much the same for most of the pictures.

    I've been using the Clone Stamp tool to get rid of dust spots. This tool tend to mess up the sky (leaving those weird circles and stains). However, the image only appears messed up when equalized.
    The more you try to fix it, the more worn out the sky will look. Despite this, the regular view of the image is OK, and the sky is fine aswell. The problem only pops up when equalizing.

    So why are pictures being rejected for a problem that is only appearing when equalizing the picture? Same goes for halos around buildings or tails. Some can't be seen when the image is normal.
    Pic looks fine when in normal view, but looks weird when equalized. Well, the equalized version isn't the one which will be displayed in database, so why even bother? That's actually what I wonder.

    Anyway, hope to see some answers soon.

    Many thanks and best regards!

    We will only reject a photo, if the fault is visible in the unequalized photo. Equalizing a photo helps to make sure, that I as screener really am seeing a dust spot (for example) and not something different, which should lead to a rejection.

    BTW, it's just a matter of learning how to use the clone stamp tool properly.

      Please provide some examples of the rejections so you can get the answers to your questions.

        Many thanks! That was helpful, i'll try to pay more attention to the clone stamp usage.

        Here's a recent one, rejected due to "Digital Manipulation" (odd rejection reason for me, but anyway... lol)
        When equalizing the pic, there's indeed a circle of the clone stamp tool at the sky. However, I swear I can't see it in normal version. The sky look perfect to me.

          Maybe you can't see it, but I don't need to equalize the photo to see those patterns.

              Instead of using the clone tool, try to use the spot healing brush. I always use it to remove dirt and dust and I've never had a problem.

                  I was about to say the same thing... clone stamp is bad. Use the spot healing brush instead as it makes a much better job of integrating/blending the pixels around it.

                    Out of curiosity: does anybody know what can cause halo to appear all around the plane like this, on the original image (not the edited file)???

                    I don't use any setting "out of place" on my camera (for example: D-Lighting, shadow enhancement systems, etc), and halos still appear from time to time.

                    They are pretty annoying TBH, because some can barely be seen on the regular unequalized pic, but will lead to a rejection anyway

                      Generally, they are caused by using the shadows/highlights tool in photoshop. I've heard D-lighting on some Nikon cameras will cause them, though it's never caused them for me(turning D-lighting off is still a good idea though). Another thing that can cause them is something like clarity or dehaze in photoshop or your camera's picture control settings. I used to have a lot of trouble halos, but they went away when I stopped using the shadows/highlights tool and when I set clarity to zero in picture control settings.

                        but i'm not talking about postprocessing issues. Some pictures simply come out of the camera already sporting halos, even with D-Lighting and other stuff turned off.

                          Very unlikely to see such halos on the raw file (not jpeg). Best to post a link to one of your images that you think has such halos.

                            As I said, it's likely due to clarity or some other setting in picture control, which is in camera. It was pretty annoying for me until I found out that the solution was in the picture control menu.
