Tunnel vision in normal parlance is inability to see other than straight ahead. What is not usually implied is that you can’t see much straight ahead either, it’s just a bright spot giving you a direction.

I’ve got myself a new Fuji X-T30. Senility adjoined as a free gift, I forgot to switch uncompressed recording on, so the above is an edited(!) jpeg. Which proves how great the new Fuji sensor really is.

What makes the image work is the leading lines coming together at 13/21 horizontally (golden ratio) and in the middle vertically. And of course the gradations (thank you, Fuji).
