I have a Shepherd Light Meter which I intend to use in the studio. I just want to be sure I am using it properly. So, here is it: How to use light meter small by http://bendthelight.me.uk, on Flickr So, I decide to read the light coming directly from the studio light, and so set the meter to "incident" with the little dome covering the sensor. I set the ISO, in this case to 100. I press the flash button on the side which triggers the flash (I have it plugged in to the unit). I read 2 LEDs. I turn the dial to "2" I read off the aperture below (in this case, f2). (measurements are given as 1/125 seconds for shutter) If I have shutter at 1/250 I need to open up by a stop (which would mean going to f1.4?) If I set the shutter at 1/60, say, I need to stop down by a stop (going to f2.8?) So does that sound right? So what if I have 2 lights? Another thing - what if I want to read reflected light? I set it to the reflected setting, but this time read the light coming from, say, a person's face. This would read a combination of more than one light? Another question - If I make a measurement of the face, reflected light, and then make a reading of reflected light from clothing, for instance, and they are different...what do i set? Hopefully there are some folks who can help...I HAVE read the manual, but the manual is about how to take readings, not what to take readings of, or why.
