comment How do histograms handle highlight and shadow clipping?
The bit depth and gamma correction are irrelevant, there's absolutely nothing stopping the camera from looking at the RAW numbers that come out of the ADC and telling the user how close to saturation they are.

comment Is it possible to get an interval precise up to 2 decimal places using a (software) intervalometer?
Sounds like that would completely screw with the plant's phototropism! Fundamentally it's possible, the camera has an internal clock which I would expect to be accurate to 2d.p., alternatively you could use the CPU clock signal or whatever is used to time the frames of a video. You'll probably need to hack the magic lantern source code yourself to do this (if you're lucky you'll just be able to hardcode the interval timer value to 1.82) however keeping the camera and turntable powered on for days at a time seems like a very difficult way to do this compared to building you own DIY turntable.

comment If PNG is Lossless Why Does Difference Blending Mode Show a Difference
PNG-24 is 8 bits per channel, if your image is 16bit then you will see differences if you save as 8bit

comment What features would cause a portrait photographer to choose a DSLR over Mirrorless?
@BBking Portrait lenses aren't any smaller if you're using a full frame mirrorless camera such as the Sony A7, so the larger grip of a DSLR may be beneficial.
