    Hi people. I recently took delivery of a sexy new Gitzo so I've been having a long-awaited crack at some long-exposures. I'm reasonably happy with what I've been getting so far, but they're by no means perfect so some feedback and suggestions on technique and stuff would be appreciated!

    Basic camera settings are RAW with long exposure NR on, pre-set white balance, manual focus, base sensitivity and 2sec delay.

  2. Some of the exposures might be a little bit too long perhaps. I would try keeping the same exposure but closing down the aperture further to increase the star effect of the point light sources. In the colour versions it is interesting to see what I assume is the different colour casts created by the various types of lighting. I wonder how the camera's auto white balance measures a scene like this.

    BTW I don't really know know what Gitzo is, but I'm assuming that it is v. cool

    Yeah, probably a bit too long...the 2nd one in particular seems rather plain/dull. Not much pop for a long exposure shot.

    Thanks! Yes I agree that the photos with lights are over-exposed... Interestingly enough, they all read about +1ev on the GH2's meter, which seems about right and shows how accurate it is, even for manual lenses and 1min exposures!

    The lighting was very tricky indeed. The council uses coloured 'mood' lighting through this area, which is fine, except that have a heap of different colours, from the yellow streetlights to green, blue and red highlights... Nightmare for WB :confused:
