Using Exposure Compensation to deliberatey underexpose

[Scheelings]

I think for all intents and purposes, the M8 and M9 work more or less the same - in principle, the technique is applicable to both cameras.

Those are great examples of when I would try to employ this technique - low light with movement. A great effort considering it was handheld!

Maybe a bit off topic, but I figured the purpose of this thread is to get a properly exposed image in low light conditions - so while I had my M8(I have no experience with the M9)
I found that I could stay at base iso of 160 and push process up to three stops in LR and still get more than acceptable results. I would usually shoot wide open at f1.9 at 1/30th, just enough to not encounter motion blur. The M8 is very capable, but the shutter sound and weight made me sell it ultimately.

Did anybody say anything different?😕

See post # 18

Ah - yes I see. Somebody introduced Auto-ISO. I think we agree.

Every digital camera has a native or base ISO, when using the base ISO the capture analogue signal is not boosted and hence you got very little or no noise and maximum dynamic range.

When you increase the ISO beyond the base level or underexpose (the same thing), the analogue signal is boosted and the amount of light captured is reduced, this results in noise but far worse is the loss of dynamic range, which means loss of tonal range, color and detail.

Think of it this way. If the base ISO is a large bucket that needs a lot water to fill, ISO 400 is a bucket two times smaller than the ISO 100 bucket. Two times less light on the sensor means two times less dynamic range.


My explanation is not very good, but essentially the point is to stay at base ISO with your digital camera unless you have no other choice... Here are some videos for better explanation of base or native ISO:
