Two Reds/half stop difference

[Michael Carn]

We recently upgraded our two cameras (748 and 1281) to B16. Set them up in the studio for a colour chart test and there was a half a stop difference on the same setup with the same lens with the in camera readings.

Any ideas?

Black balance?

 

[Seth Larney]

Yeah, what Cail said? :umm:

Black balance?

did you mean black shading ?

 

[Mike Burke]

Black balance?

How would black balance/shading affect sensitivity?
Are the shutter values the same?

 

[Antoine Baumann]

what "in camera readings"?

thanks,

Maybe use "restore" on both cameras to be absolutely sure that they are both back to factory presets, then check the side by side again.

I think Black Shading is the reason here.

I think Black Shading is the reason here.

Isn`t the reason we have black shading in the first place to calibrate each individual sensor photosite, because they can vary in sensitivity due to the manufacturing process, even across a single sensor? Wouldn`t that therefore mean a given sensor could have a higher average sensitivity compared to another? I would perform another blackshading anyway
