Well, I used a fisheye lens, so it looks even more "curvy" than it is, but apart from that and the HDR (which affects the contrast and colors, mostly) there are no editing and it appears exactly as it would if you had a 180° vertical vision ^^.
In fact this is a really small room, and I couldn't have captured so much of it without an ultra-wide-angle lens, I guess
Ah I see. But if it were curved like that and small it might even seem a bit more weird especially for people who don't like small spaces. Nonetheless it is an interesting photo. Interesting to me anyway. Have a good weekend.
