I own a Nikon D600 and my girlfriend owns a Nikon D7000.
Recently we were out doing landscape in broad daylight with our big stoppers. We have the same 10 stop filter and we came across to something I'm not able to understand. Under the exact same circumstances, for a correct exposure I had:
- ISO 50
Exposure compensation. 0
That will give me a correct (right histogram) exposure.
For her to have the same exposure she had to do:
- ISO 100
- Exposure compensation. 0
That is, she had to expose for way longer to have a proper exposure and at s bigger ISO. I though the size of the sensor wouldn't affect the quantity of light needed for an exposure but only the ISO performance.
Is this normal and a result of the sensor size? And if it is not normal... What could be the cause of this behaviour? What should I look at in settings of her camera or mine that justify such a difference in behaviour?
