What is this fascination that so many people have here to tell others how they should be taking their photos? I do this so you should... I don't find this useful so you mustn't.

The pic below was taken on a recent trip to India. It was night and the crowd in the boats were lit only by the lights from the shore. Exposure was 1/30 sec, f/2.8, ISO 6400. River Ganges after dark

Best wishes

If shooting raw & using a camera with an Exmor sensor with low read noise and low FPN, this LV 2 shot could have been taken at ISO400 or ISO 800 and boosting it in PP with a raw converter where you can apply big boosts (here 4 stops if you took the shot at ISO400), and which doesn't try and optimsie when you adjust the rendered image brightness (ie. use RawTherapee instead of LR).

Shooting this way would have preserved 4 stops of headroom, because individual sensels are much less likely to have reached FWC, When boosting in PP you could have then have fiddled with the TRC and had a better chance of rendering the bright lit areas. Think of it as much superior highlight recovery method.

BTW, is the haze in the brighter areas smoke/incense, air pollution or lens glare?
