(meteorobs) Greyscaling. a means to measure brightness....Better?

[stange34 at sbcglobal.net]

It would seem that a negative image of a wide-band greyscale,  if it were used on a computer monitor to compare with a meteor or fireball photo could more precisely determine the objects brightness by pre-assigning the reversed greyscale with standard objects of brightness. i.e., full Moon, half, quarter, Antares, etc. which would have been compared on the same monitor at an earlier time.

Any changes in recent changes in contrast & brightness of the monitor would effect both the standards(the reversed greyscale), & the meteor equally. So the calibration would remain unchanged.

The absolute brightness range of a computer monitor is limited. Not nearly so would be a display on a TV or composite monitor. The brightness is closer to actual brilliance of an object.

Reading of the "estimates" in reported meteors & fireballs seems a little loose because it is a momentary view...without benefit of a more accurate comparison to a fixed object and would be an understandable estimate.

But, if the object is captured by a video camera of any kind,  and the image is transfered & projected on a computer or composite monitor.... accuracy should be improved with a fixed(pre-calibrated) scale for comparison. Little help on this subject was found on the internet.

Has any of this been done to make some kind of standardl?
