Metering for your midtones means that you want to make sure there is an even distribution of light hitting your subject/light meter. I simply place the light meter directly in front of my subject at a 90-degree angle to me, which means it’s about at a 45-degree angle to my light source. This means that it’s getting an even reading of the light.

To meter for your shadows, which is what I recommend for film shooters, take your light meter and face it away from your light. Your light meter should still be in front of your subject, but the bulb should be facing into the shadows, or the darkest part of your image. This will ensure that the shadows are properly exposed and your negative will have the proper density.

For digital photographers, I recommend metering for your highlights. To do this, put your light meter in front of your subject and instead of facing it directly towards you, face it towards the light. This will get an accurate reading for the brightest part of your image to make sure you don’t blow the highlights or get a hot spot on your image.

I always meter with the bulb out. Some photographers suggest metering with your bulb in so that it doesn’t pick up the ambient light. But for the way that I meter, I want to get a reading that includes ambient light as well, so I meter with my bulb out.
