Hello everybody,
I have struggled with a lot of halo in my photos.
I have read in many posts that halo effect happens because of heavy sharpening. But in this image, and also some other images with the same problem I have, I did not do any sharpening or post-processing. I opened the raw file in ACR, set the sharpening and noise reduction in details panel all to zero, and this is the result. I have no idea why this happened and how should I overcome the situation.
Fujifilm X-T10, with 18-55mm on 55mm, f22, 15sec, ISO 200
