Hi all,
I want to get the values of exposure offset and gamma correction from the adjustment layer exposure.

I would really appreciate any thoughts/suggestions on the matter.

Thanks all.

There are probably 5 forum regulars with the advanced knowledge and experience of Action Manager coding who can answer this question... And I'm not one of them.

It is a fine display of communication. I'm here to learn. When I don't know something, I investigate for learning and sometimes to help.

I am enriched by the answers of people like you and I learn when someone asks and I look for the answer, if I don't know it.

I am always grateful to those who use elegance to explain my mistakes to me.

I wish that I could help and I am always impressed when one of the forum members with such knowledge posts with this esoteric information.

Add a new adjustment layer and set values = Pretty easy (script or action)

I hope that by bumping this discussion that it appears on the radar of somebody that does know.

Edit: A couple of example topics showing that this isn't a trivial request to "get" the value of "something".

Con el valor de exposición ajustas a tu gusto las altas luces. Con el de gamma , los tonos medios.

Vienes a ser como ajustar el Brillo, p.ej., pero con él se afecta toda la imagen, mientras que en tu caso sólo ajustas la parte derecha del histograma, altas luces, y con gamma su zona central, medios tonos. Son ajustes selectivos, afectando parcialmente a la imagen según uses uno u otro, y a tu modo
