No, cgbg, the primary subject in that picture was the earth, which is illuminated by sunlight. The camera is adjusted to provide detail in the bright area. The region of space that is dark was not the subject, so it was allowed to "black out". This is the very same thing that blacks out the stars in the Apollo pictures taken on the moon. The stars were not the subject, the objects on the moon were. Film, which behaves differently than digital sensors, only has an equivalent exposure latitude if 7 f-stops, or 27, or 1:128. The illumination difference between the lunar surface and a star in a dark sky would be 1:4000 or so.

So, it boils down to what the subject happens to be and the range of illumination.

Against popular belief I personally find discernment of the upmost importance and critical. I personally debunk 99% of what is presented. But there is that 1% I just cannot. I think this is extremely important to support our own honest and intelligent support or lack of support for certain concepts. :)

“The region of space that is dark was not the subject, so it was allowed to “black out”.”

Get it, similar to not being able to see the stars in the sky during a solar eclipse, even with a filter. Or not seeing the stars behind a home because of the porch light.
