Key Challenges: Very Low Lighting Without Flash Photography
Many of us are used to taking photographs under a lighted environment, and even if lighting conditions is not ideal, we would pull out our flashes.
At Night Safari, the lighting condition is far less than sufficient, which is obviously the case as the ambient lighting needs to fit the night environment for these nocturnal creatures. In addition, flash is prohibited as the bright light from the flashes may blind these nocturnal wild life.
Exactly how low or bad is the lighting condition? Just imagine with the widest aperture (F/2.8) used on ISO 25600, the camera would meter shutter speed in Aperture Priority (AP) mode to be within the range of 1/6 seconds to 1/30 seconds in most of the scenes.
Perhaps the consoling part is that these nocturnal creatures are pretty still or moving fairly slowly, which does not make it worse for the low shutter speed.

Techniques to Take Better Pictures Under Very Low Light Condition Without Flashes
Fast Lenses with Widest Aperture
Go for the lens that can give the widest aperture (i.e. smallest F-number) - will need all the lights that can get onto the sensor, hopefully without need to compensate too much on ISO and shutter speed.
With the aperture wide-open, start stepping up the ISO until a sufficient shutter speed can be metered by the camera. If the "normal" ISO range could not get you the right exposure, then ISO expansion may need to be enabled from your camera's menu so that an extended range of ISO can be used. High ISO will produce a lot of noise in the photographs taken.
Note: High ISO will produce a lot of noise in the photographs taken. So, you may want to enable high ISO noise reduction from your camera's menu if using high ISO.
Exposure Compensation (EV)
If the speed is deemed to be still too low to hand-hold the camera, set the exposure compensation down a stop if using Aperture Priority (AP) mode. Doing so will increase the shutter speed a little. The exposure can be compensated back during the post-processing.
If the shutter speed is relatively low and you do not have a good steady hand for hand-holding the camera, then using a tripod will help to prevent shakes which will result in a blur photograph taken. I've taken all Night Safari on hand-held - if I can do it, so can you :)
Anyway, a good way to gauge whether the shutter speed is fast enough to 'ignore' any slight mini movement is to check that the shutter speed is faster than the inverse focal length used i.e. if focal length is 200mm, any shutter speed lower than 1/200 seconds has higher chances to pick up any slight mini movement caused due to hand-holding the camera or mirror flipping action when camera shutter opens.
Manual Focusing May Still Be a Problem
In most of the scenes, I find that the camera was unable to automatically focus on the subject due to the extremely low light condition and I had to switch to manual focus. However, I still find that manual focusing can still be very difficult to my eyes in the dark.
If you ever run into the same problem, you may want to try out the following technique by using the AF-assist beam firing from the Flash (note: without firing off the flash).
- Attach and turn ON the flash on the camera.
- Access the camera menu and ensure that the 'AF-assist Beam Firing' is turned ON. This will enable the flash to 'fire' some red light whenever the trigger is half-pressed.
- Since flash is not allowed, the 'Flash-Firing' option in the camera menu needs to be turned OFF. This is very important, if not the flash will just go off and you will have the park attendants coming after you.
- Switch the lens focusing mode back to auto-focus mode. Now, just half-press the shutter button and the Flash will 'fire' off some red low light which will help the camera to focus on the subject.
Shoot In RAW
High noise, exposure compensation, etc ... these are strong reasons why you should be shooting in RAW so as to maximize the need for adjustments to the taken photographs during post-processing.
Other Things to Note
- Go for the 'Live Show' - lighting conditions are way much better (see picture below). You may want to note that the 'Live Show' is only available on Friday, Saturday and Public Holidays.
- Park attendants are all over the place, and you will have no chance to use flash. They will chase after you if you do so :) Please do not use flash to protect these nocturnal wild life.
- It is almost close to impossible to take good pictures during a tram ride (i.e. low light, slow shutter speed and moving). You can try but best thing is to sit back and enjoy the ride experience.
- There is strong 'dung stench' at certain part of the tram ride, and the women behind me simply throw up. Bring mask or medicated oil if you cannot take strong stench :)
