Conversation about optimizing long exposures
  •  Question A pin-sharp 40MP telephoto long-exposure, impressive technique Aristeas! I often struggle with taking stable shots with the camera pointing upwards (I believe that the vibration damping profile of most tripods is not optimised for such a position), any tips? Many thanks, Julesvernex2 (talk) 09:21, 14 December 2021 (UTC)[reply]
  •  Comment Thank you, Julesvernex2! I would be glad to share any special tips but I am sorry I do not know anything special. This photo was even taken with a simple Sirui tripod, so the tripod cannot be the reason ;–). However, for such shots I (1) always use “Electronic curtain first” to eliminate shutter shock before the exposure, (2) deactivate the stabilizers in lens and camera (they are not necessary for tripod shots and sometimes ruin them), (3) never extend the centre column of the tripod as that makes the tripod more unstable, (4) stabilise the tripod even more by hanging my backpack on the load hook at the bottom, (5) use a remote shutter release, (6) make several exposures and select the best one later, (7) wait quite long between these individual exposures to get rid of any vibrations. With wide-angle and normal lenses, I often avoid the tripod completely: I drape my jacket on the floor (or on a church pew) and place the camera directly on it. Best, --Aristeas (talk) 11:24, 14 December 2021 (UTC)[reply]
  • This is great stuff Aristeas! I do these seven things, with the notable exception of #5: instead of a remote shutter release, I use the self-timer function. That may well be the issue, as probably those 5-10 seconds are not enough to stabilise the camera/tripod when it is precariously pointing upwards... will try out a shutter release instead, cheers!
On #4, I found that using a bungee cord to hang the backpack is useful on windy days, as it allows the backpack to touch the floor rather than swinging with the wind --Julesvernex2 (talk) 12:25, 14 December 2021 (UTC)[reply]
  • It’s very good that you emphasize that point, Julesvernex2; it is often missing from the instructions, e.g. from my list ;–). When the backpack is swinging with the wind, the tripod suffers from additional vibrations; so the backpack (or whatever) must somewhat touch the ground. – A possible item (8) would be: Put something like a bean bag or sandbag on top of the camera; this stabilizes the whole installation further. (Yes, it actually does!) However, this is difficult or impossible when the camera is pointing upwards, so it does not help in the situation we are discussing here. --Aristeas (talk) 13:15, 14 December 2021 (UTC)[reply]
  • Uuuu, interesting, I'll try that on a 250mm night shot from my balcony that has been eluding me! When using a lens with a tripod collar, I assume that the sandbag goes over the lens rather than the camera, so it weights down on the tripod head? --Julesvernex2 (talk) 13:30, 14 December 2021 (UTC)[reply]
  • Yes, exactly; the bag should be over the tripod collar. (And, naturally, the sand bag must be completely tight. And the combination of camera, lens, and bag must not be too heavy for the tripod.) --Aristeas (talk) 18:30, 14 December 2021 (UTC)[reply]
  • Supplement, at Julesvernex2: I have added the hints in the parentheses not for you – I know that they will be obvious for you, just as for any experienced photographer –, but just to be on the save side if someone with less experience reads our conversation – I don’t want to be blamed for a camera and/or lens damaged by sand trickling down from a porous sand bag, etc. ;–). --Aristeas (talk) 10:40, 15 December 2021 (UTC)[reply]
  • Aristeas, I'm glad you did! While I have so far managed to steer clear of sand-related incidents, I have made plenty of other blunders, including: taking apart an old Zeiss Jena lens and not being able to get it working properly again; and crashing a drone into a river :) --Julesvernex2 (talk) 11:06, 15 December 2021 (UTC)[reply]
