In contrast, AutoRamp uses it’s own bulb timer with precision bulb times, and can adjust the camera by 1/1000 f-stop increments: 1.000, 1.001, 1.002. It will use certain preset times: 1 second, 1.3 seconds, 1.6, 2, 2.5, 3.2, 4 and so on. For example, a camera in Program mode changes settings in clunky ⅓ f-stop intervals.

In non-tech speak, that means the software is automatically optimizing exposure in the most precise f-stop intervals your camera will allow. With location information, AutoRamp calculates how fast the sun is moving, and can predict how much brighter or darker the next image should be.ĪutoRamp stands for Automatic exposure with bulb Ramping. If you specify your GPS coordinates, AutoRamp can additionally use knowledge of the sun’s position to reliably follow rapid changes in lighting at sunrise and sunset. Also, the software turns control over to you, so you can adjust the sensitivity of AutoRamp’s history stabilization. By calculating exposure from an average, AutoRamp stabilizes your time-lapse and protects it from sudden swings in brightness. AutoRamp uses an advanced algorithm to analyze a brightness history of previously captured images, and determines the optimal exposure settings for the next image. When in Program mode, your camera determines the exposure settings at the instant you touch the shutter button, which is bad news for your time-lapse when lighting is changing. AutoRamp solves this and other lighting problems - sunrises, passing cloud cover, shadows and so on - by determining the optimal settings for your camera, and then changing the camera exposure in precise, smooth increments.
Because of this, your time-lapse has a distracting flicker in brightness between frames.
As the sun sets and the sky darkens, your camera reacts by changing exposures in big ⅓ f-stop intervals. For example, a classic problem when creating high quality time-lapse footage is achieving a smooth lighting transition at sunset. AutoRamp is unique to GBTimelapse 3.1, and unlike any other software product on the market.ĪutoRamp is designed to dramatically minimize flicker when ambient lighting conditions are in flux. In this post, I explain more about AutoRamp, and the technical aspects that make it such a singular, precise and valuable tool for your time-lapse work. In the previous blog post, I announced the release of GBTimelapse 3.1, now with a powerful new feature called AutoRamp.
