Re: [Openexr-devel] converting from standard 8 bit to Half?

Is there a typical conversion from normal 8 bit images to half that will properly linearize the image so it looks "right" once displayed using the half display conversion? I'm finding my images look too dark once I to through my current process.

Are you currently using an sRGB transfer function to go from 8-bit to half?
