Is there a way to find out more about the different Holy Grail Algorithms currently on the Unleashed app and what works best for different situations. A tutorial explaining these algorithms would be very helpful.

Hey there mate
So the EV 24hr smoothing works reading directly off your cameras exposure meter, trying to hold 0 ev as the median and ramping the settings around that which you can add + or - EV to compensate it.
This works mostly ok on DSLR’s until sort of blue hour then goes haywire as the light meter can’t read the light change correctly.
Mirrorless works this mode bloody well as it’s reading direct off the sensor itself and gives a more correct reading of the scene.
LRT sunrise and LRT sunset need the usb or secondary connection and they read the luminosity of the taken photo and compare the change in that as light levels change and ramps the settings around that.
LRT Modified sunrise and LRT Modified sunset do the same but if there is a a bright light in the scene they average the exposures abit more so to stop the system making ramp changes often in that situation leading to less flicker.

The LRT modes are definitely the way forward if you have a DSLR and are trying to capture holy grail shots.
You can only choose one and ramp it that way and if you run from say sunset all the way through to sunrise it won’t work.

But that’s excessive for most people 🤣

Anyways Oliver and co can chime in for a more precise explanation.
