so your 7 studio lights are meter this and btw its a projected backdrop image. its a single exposure.
That is all I need - thank for the clarification!
-
Well it is useful, the exposure is important because knowing the scene luminosity values coming off of various surfaces is needed for me to know how the exposure will vary based and how I want those values to be stored with in my raw file for later processing (mainly the clipping point)
This is even in situations when using strobes

that was a quote from lee Jay

Discuss Exposure ? out of camera jpegs for test images.
Does fill flash/ flash (call it what you like) change exposure, that is the discussion
for the nerds. godox 685s 1/16th power 2 feet from subject now calculate the lux/sec (what ever you want to call it) that is useful for the capture of the image.

Not obvious to me...
Looking that picture you can not say if he's measuring constant light or flash ( or ambient and flash light together ) or is he only posing to do it. -

Still you can't say what he's measuring. The title of the picture, "Use of a light meter for portrait cinematography in a Turkish music video set", is hint to continuous light but what if he's acting using flashes?
MINOLTA AUTOMETER IIIF can do both.
-
Sure it did for the area that captured the image of just the flower the exposure did change, did the fill flash change the exposure over the entire image no
-
Is it not? My understanding of LV is that 'LV' is 'Luminance value' and is the meter reading - the one that you'd see behind the needle on an analogue meter such as a Weston. So far as I now, the only camera settings that would affect it is how you have the meter configured, eg spot, average. centre wighted, evaluative, etc - all of which will affect which parts of the scene the meter reads and how it evaluates them.
-
but do they take ISO into that valuation ?
-
So how would you express that in relation to the exif data this forum site displays.
-
I like this article
-
Why is this important, you must think that if it is not shown within the exif data then it really did not happen
We know the exposure is different for the flower in between the shots, on film there would be different densities in the negative, to change the density would we not have to alter the exposure for that area. With digital we know that the exposure was altered because more light was captured as shown in the raw, or where the image processing that created the image placed that flower within the tonal range of the image. -
scene luminance measurement is basically useless in the field when establishing exposure settings after reading this article, its up to the photographer. which is probably why camera companies and the like dont take scene luminance into account as a measurement to establish a suitable exposure.

Ok the penny has dropped. and i conceive defeat . well sort of
conclusion: exposure = shutter, t stop, and scene luminance which is displayed by the histogram now we have practical picture (pun) to work off.
come on guys you have dropped the ball explaining the concept to the limited scientific minds. 😎
My fees are cheap if you want to quote my conclusion. 😁

Finally.... 😴😴😴
