Re: The lighting is the same...

Instead of using different exposures to get the correct image brightness, wouldn't it make more sense to use the same exposures and to then brighten the darker image on the computer? These high-ISO tests are really about how well different cameras cope when their sensors receive "inadequate" light. When a shot by one of the cameras gets more exposure, i.e., more light on its sensor, how meaningful is a comparison of the resulting photos?

You mean like the way people take photographs? Going out, shooting at a set exposure and then digitally correcting the image brightness later.

We may well add a test that shoots in low light, once we've worked out the fine detail of doing so, but this test is based much more on the fact that most people shoot their images to achieve a particular image brightness, not to use specific settings.
