Originally posted by normhead It's not the meter being used. It's the fact that they've learned to interpret what the meter is telling them. With the EV controls on a TTL meter, you can do the same. Learn to interpret based on circumstances. -2 for a sunset, +2 for backlit in snow. Etc. etc. The idea that you can't expose appropriately with a TTL meter is nonsense.
I wore out my Lunasix 3, although it lasted me 30 years, buy the time it was done, so was my need for a hand held meter.
Being able to chimp and check exposures with histograms was the last straw.
These days, the only excuse for using a hand held meter is your camera doesn't have one built in.
No one said you can't use TTL, but it's a kludge. All that faffing about with +/- EV compensation for white snow, black dance theatre backgrounds, dark shrubs, and bright clouds is the photographer trying to correct for the errors made by the TTL system. EV compensation is the photographer's attempt to estimate the incident light from a reflected light meter reading off something of roughly-known reflectance.
People with a lot of photographic experience know that the TTL meter is sometimes wrong, know when its likely to be wrong, know the reflectances of different materials, and know how to correct the TTL measurement of reflected light to get a proper exposure based on the incident light.
It's the beginner who thinks that their camera's TTL meter is the voice of the gods who becomes mislead and wonders why they got gray snow, gloomy beaches, and blown-out clouds and ballerinas. Some of them switch to spot metering and get even crazier results because no one ever told them what TTL metering was doing and why it can make mistakes.
That said, modern TTL meters have gotten a lot better through the use of matrix sensors and clever algorithms that often automagically correct for scenes that are not the proverbial middle gray. At one level, that's great for a lot of shooting. At another level, it reinforces that idea that the TTL meter is always right. It's now right a lot more often but it's still wrong sometimes and the automagical EV compensation inside the matrix reading algorithm makes it a bit harder to know how much manual EV compensation to add.
Chimping, live view, and histograms are certainly one modern solution although that won't help the OP who's talking about film cameras such as the Leica M6.
