FOR EAXAMPLE WE ARE INSIDE BUS

OPTION A
I see Your face there where Your face is right now ( fresh position ) ?


.Me
.i

.i Vo = ABSOLUTE ZERO

.You

OR

OPTION B
I see Your face there where Your face was in past ( light need short time for propagation )


I see Your face there where Your face was in past = I will register lower Intensity


The Inverse Square Law and Practical Photography

> source School Of Digital Photography: The Inverse Square Law and Practical Photography

So in the previous article, The Inverse Square Law of Light, we discussed the theory, now let us take a look at how we put what we have learned to practice. We are now clear that the power of the light will be inversely proportional to the square of the distance.

Let us see how the inverse square law affects Exposure.



It is clear from the above diagram that the strobe has its maximum output in close ranges, but its intensity falls off quickly as the distance increases.



Ok what is the reason that I see Your face in old position ?
Can I use brightness to evaluate motion ?



different between stationary situation and motion ???

stationary sytuation

SUN -----------------------Earth

motion
p1...p2...p3...p4...p5...SUN -----------------------Earth ------> motion






ABOVE MICHELSON MORLEY BRIGHTNESS VERSION !!!
BELOW CONSEQUENCE FOR EINSTEIN
