For example, 250 Illuminance diff would equal about 0.33 EV. These values are relative to the exposure value. If your image exposure change too slow, decrease Illuminance diff. If your image exposure changes too quickly, increase Illuminance diff. Illuminance diff actually control speed of this transitions. ![]() If they are too bright then it is necessary to decrease it. If they are too bright then it is necessary to increase it.įor Night to Day transitions, if the daytime photos are too dark, it is necessary to increase the Day Illuminance Modifier value. But in the some scenarios or when you want to take pictures in environments with different light levels, it may be necessary to use these values.įor Day to Night transitions, if night photos are too dark, it is necessary to decrease the Night Illuminance Modifier value. Under normal conditions, these values do not need to be touched. We have also advanced parameters screen which includes Night Illuminance Modifier, Day Illuminance Modifier and Illuminance diff. Range: This screen will be used to define the limits for Shutter Speed, ISO and Aperture values and their priority. You can find the recommended interval values below: Interval: This parameter defines the duration between the starting points of each frame exposure. If you set the frame number to 0, this will mean that the time-lapse will continue until you stop it. You can set the frame number up to 65543. If you choose Manual Mode, Range Parameter s will be enabled so that you can define the limits for Shutter Speed, ISO and Aperture values and their priority.įrame:This parameter defines how many photos will be taken. When Auto Mode is selected, Flex will decide over Shutter Speed, ISO and Aperture parameters and their priority according to light level changes. Type: You can switch between Manual Mode and Auto Mode using this parameter. Set the camera settings in order to get a correctly exposed image. Then set your shutter speed so that your frame is exposed properly. Set your ISO to the lowest possible (e.g, 100). First set your aperture the lowest possible (e.g., f/2.8, f4.0) Make sure White Balance (color temperature) is not set to auto. Make sure your camera is in Manual mode. ![]() But make sure your shot is properly focused. Turn off “ Image Stabilization” and “ Auto Focus” before starting your time lapse. Note: The best time to start your timelapse session would be half or one hour before sunset and sunrise time according to your location. Thanks to this flow, night-day-night transitions are extremely smooth. According to the difference, the aperture, ISO and shutter speed values of the camera are changed, in order to take photos with the same EV value as the reference photo. ![]() Then, it calculates the new EV value using the reference photo. Holy Grail mode of Flex takes the first photo and sets the reference value. The Holy Grail time-lapse mode ensures that every photo in timelapse shots is properly exposed and properly ramped (changing smoothly) between any setting changes. While shooting Holy Grail Time-lapse, there is a need for a way to keep the exposure correct as the light constantly changes. Otherwise, the photos taken can be too bright or too dark.Įxposure in cameras is a complex term that depends on multiple parameters such as shutter speed, ISO and aperture. For this reason, exposure settings need to be changed dynamically during sunrise and sunset shots. ![]() As the ambient light is constantly changing during this process, the amount of light hitting the camera's sensor also changes. Holy Grail Time-lapse is the version of standard time-lapse photography during day-to-night or night-to-day transitions.
