Whilst reviewing pictures with "c"ompare, I started to notice that some photographs are different even though they should be the same. Why should they be the same? Same shutter speed, same f-stop, less than a second apart - continuous shooting of a static subject. And indeed, the histogram is different.
Is this the camera's fault or is this Lightroom's fault?
I suppose "fault" is the wrong word to use but in some cases, the sky is quite visibly rendered a darker/lighter hue.
Is this a mechanical problem (slight variation in slow shutter speeds impacting exposure)?
Is this due to the sensor (warm vs cold)?
Or is it that Lightroom decides to render the same scene differently because the inputs are so slightly different and it's like a journey where after you take one right turn, instead of a left, the path is never the same (and thus the destination is always slightly different)?
Or is this just natural for (digital?) photography and that I'm noticing now is only because I've never pixel peeped to this level before?
