Go Pro Hero 7 Native ISO question

Hey all,

What’s the Native ISO for the 7? And what exactly is the sensor doing when you go up or down in ISO? Is it putting in an ND when you go down in ISO? Is it ever cropping the sensor when you switch ISO’s? Any help would be greatly appreciated.

Re: Go Pro Hero 7 Native ISO question

Hello
As far I know


By default it is adjustable Iso (from 100 to 1000)
You can fix the iso or reduce the range (ex 100 to 400)
I believe you must go to protune menu

But there is a very interesting setting useful if you are filming from inside your car with
Dark area (dashboard) and clear area (windscreen)
By default the iso setting will be medium
I will explain how to put the spot measure on the wind screen

Put your finger on the screen for 2 seconds

A white rectangle will appear ( the area of measure)

Move your finger in the direction of the windscreen

The rectangle will transform in a small square

Move it in the appropriate area !

Your video will be perfect on this area (under exposed for the inside but who cares .. )

The default ISO is variable, ranging between 100 - 1600
ISO up or down is often referred to as the "sensitivity". It's basically how much of a charge each pixel on the sensor gets. The higher the charge, the brighter the pixel. The brighter the pixel the more "excited" it gets. The more excited the pixel, the more noise it makes.

There is no ND involved.

However, the EV does simulate an ND.

No cropping is applied.

Hello Daniel !
ND is for Neutral Density Filter ?
