A Day to Night Bulb-Ramped Timelapse
starting at or just before sunset,
with NO ND filters used, and
ending 1 hour past astronomical twilight.
I started at 1/15th of a second at ISO 50 and ended up three hours later at 30 seconds at ISO 3200.
1. Establish your composition.
2. Consider graduated ND filters
3. Set your start exposure in M mode
4. Try to shoot wide open
5. Take a test shot, histogram slightly right-justified
6. CHECK YOUR FOCUS – I like to use Live View at 5x or 10x to do this
7. Be careful not to dislodge your lens if you twisted it halfway off
8. Connect the Promote – Bramp assist cable via PC hotshoe adapter, CN3 shutter cable, and USB cable to your camera.
9. Promote and camera are set as above
10. Make sure you camera is in M mode, and that the camera is set at the ISO and shutter speed you want to START the timelapse at (ISO 50 / 1/15th”)
11. Take your camera out of Live View!
12. Take a few test shots, and CHECK YOUR FOCUS.
13. Pick up the Promote, and enter the Bulb-Ramping menu, you should see this screen:
14. Setup as follows:
–Start Tv (1/15th”) [This should match your test shots]
–Each (15 seconds) [You can make this much smaller, the Promote will ramp up the interval depending on whether you set Setup #18]
–Begin Ramp in (01h00m) [Or, start ramping now depending on how close you are to the begining of dusk/twilight]
–End exposure value (32m – yes, 32 minutes)
–Finish seq in (03h44m) [This is the time the timelapse will stop shooting.]
15. Press “Start” to enter the advanced Bulb-Ramping menu
–ND:(none)
