v1.8.53

• If the image was overexposed, returning to normal, stable values could take many frames to recover. Fix that.
• Introduce a new method to calculate day and night luminance references. Previously, if the image was slightly underexposed, your day/night reference luminance values could be incorrect, resulting in your reference photo being out of the range of reference values.
• Show estimated photo luminance on the main VIEW screen during timelapse. In short, it is an analogue of exposure compensation in your camera. VIEW tries to ramp this value from -1.5 at night by default, to 0.
  
• Add histogram and photo luminance values to "Exposure" and "Capture."
  
• Various fixes

v1.8.52

1.8.52

• Implemented a new method for calculating the histogram. Past experiences highlighted many overexposed timelapses due to incorrect histogram calculations, leading to failures in actual highlights protection algorithms. Day and night luminance calculations are now more precise, based on the YUV colorspace formula. Adjust your luminance references accordingly for day and night.
• Revised the sunrise ramping algorithm. Previously, the algorithm sometimes hesitated to adjust to the increasing light levels in the mornings. It has been modified to ramp faster towards brighter conditions.
• Enhanced camera exposure values in balance mode (S=A=I). If previous change in one direction was of the same parameter, then the opposite direction change will be of the same parameter. Except iso in up direction, we want it to ramp as quickly as possible.
  For instance, transitioning to darkness with the previous algorithm: 6s 5.6f, 8s 5.6f(s), 8s 4f(a), 10s 4f(s) -> transitioning light -> 10s 5.6f(a) -> transitioning dark -> 12s 5.6f(s). Notice that the shutter and aperture change sequentially, which can lead to a peculiar situation where you may end up with a longer shutter speed instead of a wider aperture at night.
  The new algorithm will maintain the adjusted parameter sequence: 6s 5.6f, 8s 5.6f(s), 8s 4f(a), 10s 4f(s) -> transitioning light -> 8s 4f(s) -> transitioning dark -> 10s 4f(s). Notice that the aperture remains unchanged as the EV decreases and increases.
• In balance mode (S=A=I), ISO will consistently be the last parameter to change when transitioning to darker settings and the first parameter to adjust when transitioning to brighter settings.
