Lightmeter is very much still relevant today. We are still getting exposure value for a recording media, just the media have change that all. During the past in studio you can not do without a studio flash light meter. In a studio flash light meter make it easier for us to get the right exposure in a studio woking enviroment. What I had experience with the new digital media, in outdoor situation we need the lightmeter even more. If you want to have good exposure to ensure you have best informention on your picture as the digital media latitude or tolerance is very small (1 and half stop compare to 3 stop on film). Some of us like to trust our LCD when looking for exposure confirmation on our camera's LCD. :nono: It is a sure way, only if you calibrated the LCD well. Otherwise how many of us go back after a photography session only to find to our pictures are not right after we download our stuff.
It's the type of different metering devices and methods out there, is what you have to decide which is more accurate. They are mainly two type of meters, the incident or the reflected one. The common point in any meter s' design is to meter one standard which is the 18% grey or zone V in the zone system.
The ones on our DLSR or film cameras are reflected one. But in order to get the best out of a reflected meter need a photographer who are good in metering. Mainly he or she need to need how to meter the subject right to get his or her desired end result. As there are many different shades of exposure or zones as in the zone system that can trick a reflected meter. A method is commonly use is to meter things that are zone V or 18% grey. Herence the Kodak 18% grey card a cheap but effective metering assiting
tool. Then there are expert who know how use a spot meter. A spot meter is very much like a sniper rifle and the camera meter no matter how smart a camera maker like you to think their meter are it is a shot gun. If you are not a markmen use the shot gun first :bsmilie: untill you learn euongh to shoot well, then snipe rilfe?
Then there are incident ones, they are the ones with the white hemisphere on them. These need you to go up close and personal to the subject to meter them. But they are the most accurate one when use correctly. It will meter 18% grey or zone V on the subject without even need of using a kodak 18% grey card.
Now a day of two in one and three in one stuff. So are the design of hand held meters. Now you can get a incident and reflected meter in one. It not how big it is but how you use it. :sweatsm: I hope this helpful to you
