Long exposures can be hit or miss. To improve the hit rate, I:
- Use in camera long exposure noise reduction
- Use a solid tripod or camera support (rock, log, table, etc) and a remote shutter release
- Start with no filter on
- Find the focus point and use auto focus
- Turn off Auto-focus (or just turn off focus on shutter release to start with or just manual focus)
- Use aperture priority mode and dial in the ISO and f/stop to what you want
- Go to full manual mode
- Set the shutter speed to bulb mode
- Use a smart phone App to calculate a new exposure time using the original metered shutter speed
- Put the filter on and time out your exposure using the App data
- Note that if you use in camera noise reduction, the camera will need to process the data for a time ~ equal to the exposure time
Have fun. If I haven't done long exposure in a while, I will practice a shot or two at home before leaving on a trip.
