Just some additional information about setting the exposure slider:
It not only depends on the camera itself, but can also depend on the characteristics of the scene. In the article above, you see a different exposure setting is needed depending whether the subject is in the open daylight or shaded under the tree. The way to do it scientifically is to have a 18% grey card in the shot next to your subject, and you can compare the grey card to the grey border when you turn on the color assessment mode. If you have trouble seeing it, the global color picker in Lab mode can be helpful – the L value should be around 50% if you select the grey card. But normally it is enough to simply adjust the exposure slider until your subject is bright enough to your taste.
You’ll find that on average, your camera’s metering, together with a default bump in exposure from your preset, will give you a reasonable starting point, but camera’s metering can be fooled by scenes with lots of dark tones, or scenes with lots of light tones (like in the snow). So, you may still need to tweak the exposure from the default setting in your preset.
