The reason I left the foreground in was to create a sense of depth? I had the aperture at f22 for this reason also, not sure if it worked. I shot this at 18mm on my kit lens hence the curved horizon!
Yes I noticed that myself about the sun burning through however I didn’t not know how to prevent this when I was editing? I’m not long at photography I got my camera roughly 4 months ago so I’m still learning. I could be wrong but I think those are the Aran Islands!
