Question from a Reader Via Email on Night HDR Photography
I went to do a night hdr the other night and I guess that because the scene is very dark I would need more over exposures than under right? What I noticed with my camera (Canon 7D) is that there was no difference to the picture from +2 EV and +3 because they were both 30 second exposures. Now here comes my point / confusion, I set the camera to BULB mode and took some shots, one at 60 seconds, another at 120 seconds, another at 180 seconds, right up to 5 minutes which made a difference, but how do I know what EV they are because it doesn’t say and Photomatix wants to know these values? I remember you stating in a previous email that you play with the settings in manual mode and bracket from that prefered exposure. The scene I had didnt have much light in it, unlike the one that you linked me to the other week, which brings me on to another question and that would be, does night HDR only work where the subject is a cityscape which has lights from the city and cars etc…. My scene was of a light house, only the lighthouse doesnt have lights because its not in use. I was at this scene around 11pm, so it was pretty dark.
