Startrail timelapse tutorial1/9/2023 ![]() If I want an even longer exposure, I add a neutral density filter, which reduces the amount of light that can reach the sensor.įor the shot below, I tested my composition and exposure with a shutter speed of 1/30 of a second at f/2.8. This aperture is small enough to reduce light, and is the sharpest aperture in my lens. Generally, for long exposures I use an aperture of f/16 for the final shot.

The TriggerTrap app has four basic cable release modes: Simple Cable Release, Press and Hold, Press and Lock and Timed Release. Cable releases, or TriggerTrap and your phone, stop you from physically touching your camera and so keep your images sharp. Even if your shutter speed is 1/30s or faster, pressing the shutter button on your camera can cause it to shake and introduce blur to your images. If you are shooting with a tripod, and especially if you’re shooting with a slow shutter speed, you should use some sort of cable release. The simplest example of this is the app’s cable release modes. Cable Release and Long ExposureĪt its most basic, the TriggerTrap app and dongle let you use your phone to trigger your camera. Depending on what TriggerTrap mode you are using, you may need to set the shutter speed on your camera, or else to set your camera to Bulb and use TriggerTrap to set the exposure time.Īs a general rule, if you are taking a long exposure shot your camera needs to be in bulb and you set the shutter speed using TriggerTrap if you are taking a timelapse, you set the shutter speed on your camera. Either focus the shot using autofocus and then switch your camera to manual focus, or just focus manually.Īperture and ISO are always set, as normal, on your camera. TrigerTrap requires that your camera be in manual focus mode. ![]() Camera Settingsīefore doing anything with TriggerTrap, you need to set your camera up. ![]() To use the TriggerTrap mobile dongle with your camera you’ll need the app. The TriggerTrap app is available for free in the iOS and Android app stores.
