Your link doesn't work. Maybe you need to learn how to create a link using the link icon in the post editor. You can't just paste a link into a post like you have as shown below.

your method did the same i have to right click still

Not all browser work the same way. I posted the correct link using the link icon in the post editor in my previous post. Doing it that way it will work in all browsers.

thanks fixed

I'm not so sure.
The very first line, yes the very first line 😄 says:
"A photographic exposure is dependent upon three variables: aperture, shutter speed and ISO."
It should be "A photograph's lightness is dependent upon three variables: aperture, shutter speed and ISO."
I can change ISO without altering the exposure* at all.
* exposure - amount of light that struck the sensor per unit area while the shutter was open
** optimal exposure - the maximum exposure* within dof and motion blur requirements without clipping important highlights.
*** under exposed - more exposure* could have been added with the DOF and blur constraints still being met without clipping important highlights. -
That article then goes on to say
"Aperture + Shutter Speed + ISO = Exposure"
which again is nonsense because I can change ISO without altering the exposure* at all.
That statement should be "Aperture + Shutter Speed + ISO = Image Lightness".
Image lightness and exposure*, although related, are 2 different things.
* exposure - amount of light that struck the sensor per unit area while the shutter was open
** optimal exposure - the maximum exposure* within dof and motion blur requirements without clipping important highlights.
*** under exposed - more exposure* could have been added with the DOF and blur constraints still being met without clipping important highlights. -

If you take out the errors in it.
