[REQ] saving Metadata in PNG

[Zom-B]

Hey Guys...

Saving some Infos inside the PNG Files would be nice I think.
From standart Data like Artist to Render like Infos Indigo version, Rendertime Mutaions...

Here you can find a Chunk overview

Perhapes this free command Line Prog PNGCRUSH may be interesting too!

Yes a great idea... but for camera data and film we will first
have to get some units into Indigo ...
as long as i can't set an exact amount on light .. like Watt or Watt/m² .. it's pretty heavy to come up with a correct exposure system..

the system i use right now in M2I is only quite Ok when using
sky... with emitters i'm pretty lost as nothing seems to fit..

If we would have some units we could do some tests comparing
with Maxwell assuming that their exposure system is physically
correct ...

cheers
