LUMU 101: SPOT METERING

WHAT IS… SPOT METERING?

Spot metering offers us the ability to measure the correct exposure on a certain fixed point. By measuring the light that is reflected off a chosen surface, it tells the aperture you need, to achieve the 18% (middle) gray level on your selected subject.

 

While spot metering is useful in a variety of scenarios, it’s most common use is when you’re shooting scenes with multiple light levels. For example, when your subject is in a deep shadow, or under a spotlight. Perhaps you are shooting the outside enviroment through a window, or your subject is backlit - the options are endless.

 

LESS IS MORE

But where spot metering really shines is macro photography. Measuring the correct exposure will slightly darken your background, highlighting your macro subject.

Hi,

Just found this and am loving the Spotmeter function.

Had a suggestion to add a memory function that could then average between memory inputs
for zone metering.

Say you take a spot reading of a shadow area, get the reading and hit the memory button
which would then store it in memory. Then take a reading of a bright area, hit the memory
button it then adds that in to memory. Next to the memory button it now reads 2, meaning
there’s two readings in memory. (You could expanded the memory to hold more of course.)
Tap an “Average” button and it automatically averages the two or more readings to give
you an exposure.

Seems like a fairly simple memory and math update to a very useful app.

Another thought is adding a grey scale slider representing the zone system right below the
view window but above the aperture. Middle grey sits dead center and after you take a
reading you could slide the grey scale left or right to get the shutter and aperture scales
to adjust according to the grey that is in the center.

Just some thoughts, or maybe it does this already and I haven’t found it.

Thanks –ron
