Your picture per se isnt under-exposed; only parts of it are. Be careful changing exposure as you can then lose the colour saturation too. Have you got an EV setting on your camera?

I've adjusted levels and dodged/burned key areas to lift the relief and add lightness to the appropriate areas, and add the missing drama.

All-in-all, it's down to personal preference what pleases the eye.

PS: I didnt realise there was a church smack in the middle of your picture until I started to adjust the levels.

lol snapper now i have four for the price of one !

lol after all these four edits, i just relise there is a van at the bottom of the road !

Too right, still like yours but I also like the one Jack R has done as it retains the feel which I guess is why you took it in the first place.
