  • JPG Sky Artifact Removal

    Hey folks, Any suggestions for removing artifacts in the sky areas? I have Photoshop CS5 and rarely use layers. I do a lot of selecting areas and working that way. Any suggestions or tutorials. Thanks,,,,,,,,Steve

    1) would need to see examples to know exactly what you are talking about
    2) if they were not natively in the scene/image, best way to 'remove' things is to avoid them being there in the first place.

      Hello Steve,
      Humbly I would try my contribution here:


      I've addressed this issue a number of times on this forum, appealed a number of rejected photos with JPEG-Compression artifacts, investigate this phenomenon on the web, approached Canon corp. UK advisers, thereafter with a help of a scientist expert of light-photons who is working in a High-Tech co., and the conclusion learnt is this:

      The basic of this phenomenon is light-heat differentials, measured by Kelvin-Numbers, when greater than 8000 (on hot sky) would create radiant-spots i.e. artifacts on the "sky" space of the picture and /or upon the outlines of the plane fuselage (compression by itself would also happened when there is too much/extensive crop of the original picture).

      I do PP only with Canon-DPP, do not apply any further process – and yet, most of my "summer photos" of planes have some sort of artifacts.
      I do not know of any software that can remove artifacts.
      So, as Dana stated – try to avoid them, take photos on early mornings. Reckon it occurred mostly in late spring through summer – especially if you live in a hot country, Israel is my home-base.

      Hope I managed to clarify by a bit.

        Hey Steve, just an opinion.

        Sometimes i do experience some of them...I usually use Lightroom's Masking tool and do about 40 plus everytime (Should do the job)

        If they are in the image originally, like what Dana said, would be advisible to avoid it instead.

        Hope this helps

          Hi Steve, can you show an example of a photo of yours that has the issue? For the purposes of our hobby here avoiding JPEG compression is usually a matter of dialing back noise reduction and making sure to save at max available quality at all stages of capture and processing. Fixing a photo with compressed sky is possible but it's usually better (faster, better results, less likely to create other problems) to go back to the beginning and re-process without introducing the compression.

          Regards,

          Alex

            Thanks for the help and information guys. There are a million ways to somewhat reduce the artifacts, but I'd like to completely remove the whole mess with a blur or something like selecting the sky and adding color or something. Anyway, Thanks for the info. Check this picture and the sky area. Click image for larger version
