The View can also be controlled from a web-based app on any device with a web browser. You can program the View with its intuitive menu but I prefer to use the free TL+View app (iOS and Android) to program, monitor, and even override my time-lapse sequences. (See below to learn how to edit a varying White Balance with Timelapse+ Studio.) Since I always shoot in Raw I leave the white balance set to Auto (AWB) and edit the values in post-processing. This initial setup will ensure that the sequence will not be overexposed. To shoot a day-to-night sequence, one sets the camera to the lowest ISO and the appropriate shutter speed, making sure that no highlights are clipped. It writes image files to either the camera memory card or to an SD card in the unit itself. The View works with many camera models from Nikon, Canon, Sony, Panasonic, Fuji and Olympus, and works with most motion control systems for shoot-move-shoot functionality and motion keyrame integration. It sits on the camera hot shoe and is connected to the camera via a USB cable (simultaneous multi-camera control is supported via an optional USB port). The View has an internal battery which can be recharged via a Micro-B USB cable connected to a power device or AC outlet adapter. With the Timelapse+ View you can correctly expose the first frame of a sequence and let its auto ramping mode do the rest of the work. At the same time, the View ignores transient sources of light such as headlights. ![]() Then it predicts the correct exposure for the next frame and sets it accordingly on the camera. The View is an intervalometer and exposure ramper that uses algorithms to analyze the last several exposures and determine how the lighting conditions are changing. ![]() Consequently, a lot of trial and error might be required. For changes involving the Sun and the Moon, this light curve will depend on the day of the year and your latitude on Earth. Some devices require that you know beforehand how the light is going to change as a function of time (that is, a light curve) and program the device accordingly. (Nikon D700 and Nikkor 14-24mm F2.8) Timelapse+ View (the hardware)Īll that hassle and limitation can be eliminated with the use of an exposure ramper, a device that progressively changes the exposure according to the lighting conditions. I optimized the exposure to correctly capture the night sky, but as a result the afternoon and morning sequences were completely overexposed. These time-lapse sequences illustrate the challenge that the Timelapse+ View aims to solve. (More on how to do this in the Timelapse+ Studio for Non-Ramped Sequences section below.) I would then try to salvage as many evening and morning twilight frames as possible by reducing the exposure value and recovering highlight information in post-processing. The sequence would start completely overexposed but would become correctly exposed as it got darker. ![]() Whenever I needed to leave my camera unattended I would expose for the nighttime conditions (mainly considering the Moon's brightness) and start my time-lapse sequence before sunset. I started photographing astronomical observatories 12 years ago. It retails for $399 and it includes Timelapse+ Studio, a Lightroom plugin for processing the timelapse sequences. That's where the Timelapse+ View intervalometer, a device designed to automate day-to-night time-lapse sequences, comes in. It's also unlikely that your camera's Auto Exposure mode will give you proper results, especially during low light conditions. For example, sequences shot during periods of time covering sunrises, sunsets, moonrises and moonsets are difficult because a single set of exposure parameters won't work for the entire sequence. ![]() Even if you're only a casual time-lapse photographer then you probably know how challenging it can be to shoot a time-lapse sequence that involves drastic changes in lighting conditions.
