Hi Ian,

Do you have any further information on which Olympus cameras that this update in ACR 5.5 refers to:

Camera Raw 5.5 and Lightroom 2.5 include a correction to the demosaic algorithms for Bayer sensor cameras with unequal green response. Olympus, Panasonic and Sony are among the more popular camera manufacturers affected by this change

It seems to have added the E-P1 to the list of supported cameras for ACR.

I think Invicta is referring to the quote (not sure where that comes from) concerning sensor characteristics apparently pertaining to some Olympus, Panasonic and Sony cameras.

I know Sony and Nikon have experimented with sensors that have two sets of different shades of green bayer filter pixels on the sensor. Kodak have also experimented with half the pixels that would normally have green filters over them actually having clear filters. I wasn't aware that Panasonic used modified green filters in its sensors (which are now also used by Olympus).

Hi Ian, yes I was referring to the sensor characteristics. The info is in the release notes, page 7 at
