Hi everybody,
Last night, I see a beautiful sky and fortunately I just have my tripod and Fuji XT-1 with 18-135 zoom with me. So I decide to take my first shot at night.
I was slightly disappointed by a strange artefact I saw on my picture and I decide to ask the question to the expert of this forum...
When I put maximum clarity on my shots (and it's also noticeable without), I see a light circle on the picture much more noticeable in the thumbnail or when you are far from your screen.
Don't look at the image quality, it was just test shot.
EXIF : 18mm 15 sec f3.5 iso 3200
Anybody knows why this circle appears ?
