Photography Question

What is the best method of metering?


I have read a lot recently about the advantages of incident and reflective light metering, as well as spot metering. With my 35mm camera as well as my SLR digital Canon, I have been taking light readings of the subject and with the exposure lock, using the exposure that the camera's light meter reads. I have also utilized grey cards to get exposure readings. My camera's light reading can be set to evaluative, center weighted or partial. Which is the best setting when you zoom in on a subject to get the best reading? Also, is it better to use a handheld incident or spot meter?

  "Meter for the highlights, and let the shadows fall where they may."
(I remember reading this many years ago, and wish I could remember the source so I could credit the author.)

For in-camera metering, this guideline runs through my head whenever I'm faced with a situation when high-contrast light levels within a scene wreaks havoc with my in-camera meter, and I'm in the field without a hand-held ambient light meter or gray card...(especiallly when shooting macros or tight tele-photos.)

The advantage of incident light metering is that it gives you an average reading of the light falling on the subject, or subjects, and will balance exposure to all light levels. This is where a gray card or hand-held meter can be a real asset. Whenever possible, use these tools to balance exposure.
If you want to use the exposure lock feature on your cameras, lock on to a neutral shade or color within the scene which appears evenly lit..(not too bright or too dark). This exposure setting will be close to what an incident meter or gray card would recommend.

  Thank you so much for your explanation. It seems as if grey card and incident meter readings are preferred over TTL readings. I had been using a gray card for a long time and then found that the camera's meter provides a good reading when I zoom in on a particular area. I think I will use a gray card and compare results.
