I am curious about those ghost-like concentric circles in the sky background. happened to one of my landscape photos too. Can someone explain this phenomenon? Mine was taken with a Canon.
In my case, that's banding artifact due to high software compression. I exported from Lightroom with a size limiter of some ridiculously small size. Fm website may have further compressed it. I have the original file and it's perfectly fine.
In real practice, I see banding in video when using a camera with a small color space. There's only so many shades of blue that the camera can understand so you'll notice the bands in the sky. Eg Panasonic Gh4 with a depth of 8bit vs the gh5 with 10bit In practice, it's barely noticeable and hasn't been a concern for me. But if one were to pixle peep, you can notice it in video and picture. I'm sure someone inderstands this stuff alot more than I, maybe they can chime in. dalite wrote:

So how does one fix that problem?My original, like yours is also OK. What to do in PP?...Show more →
I think FM let's you post up to 4mb? Try to export to that size. I share the full res images with the clients so it's not a problem for me.

Hey, I just got this lens. You mentioned an EFCS issue causing bokeh problems? Can you explain what you mean by that? I was under the impression there's no reason to ever really turn EFCS off.
