@browneyedgirl89. I’m not sure what you mean by being taught to expose with metering, but my point was whether you review the photo, then adjust exposure to taste – or do you just use the built in meter, adjust, then shoot. Say you didn’t have an LCD to review the shot/histogram – would you be able to get close to the same picture using the built in meter alone?
I know this sounds a bit pedantic (it probably is), but in reality the LCD can fool you, especially in bright light. And histograms are only IMHO useful in “double checking” your particular subject that you’ve metered, and only if that subject completely dominates the frame eg. zooming in on grass (“0” ev), or a white dress (+1.7 ev) or a grey card(generally “0”). Check the spike in the histogram, if it correlates to your metered value, then you should be good to go.
Don’t get me wrong, I use the LCD all the time, especially for the “creative” exposures – but it is good to fully understand what the meter is telling you. I know if I was a working pro, especially with heavy flash use, I would have an indecent meter for sure. No guessing, and very consistent. The expo disc is supposed to be very good as well, but of course is no good for flash exposures.
