Canon PowerShot G15 review
Generally, the evaluative metering system performed well with a clear emphasis on making sure that the foreground subject of a scene is bright and well exposed. My only complaint is that the camera tends to create bright skies with little detail, as will be discussed in the Dynamic Range section. I found that when taking landscape images, I had to use spot or centreweighted metering and take a reading from close to the brightest point in the sky to make sure there was very little burnt-out detail. This did, of course, mean having to push the shadows, but there was enough detail to be able to do this, and by using lower sensitivities not too much noise was introduced.
At other times a quick turn of the exposure compensation dial was all that was needed to reduce the exposure, from between -0.3 and -1EV. In many ways, this ability to change the exposure using the compensation dial is one of the G15's best features. After all, when the exposure is correct there is no problem, but when it needs adjusting, having the option to do it very quickly via a dedicated wheel, rather than fiddling around with buttons and dials on the rear of the cameras, is a real bonus.
