I"m a believer in trying to get the results in Camera rather than relying on Software. Which TBH if you"re shooting in the dark you don"t have much choice, & that"as why you don"t see the HDR Photomatix boys in Tunnels shooting multiple shots lol
It"s also hard to compare reports of locations purely on how they"re both lit 7 shot by individuals. And of course as well as by what means of lighting ie we"ve gone from the old Yellow lights of old onto Cree LED units of Blue light onto the cool white we now have today.....well some of us
As for the ? of fully lighting a Tunnel, i like to see the colours and natural features inside, how can you show a tunnel as you see it in total darkness ? all you have is light from the portals and possibly light from any airshafts the tunnel may contain.
Shoot & light it as you want & fuck everyone else (including me
just sharing what i do for my shit
