There's been discussion elsewhere on the forum about how to demosaic images that come down as raw pixel values from cameras with Bayer filters, but I have not been able to do this myself and am looking for some help. What do you folks recommend to demosaic images? I'm a Windows user...
In this post Damia recommended ImageJ with the Debayer plugin. I downloaded ImageJ (now Fiji) from here and the Debayer plugin from here as well as the PDS Reader plugin from here. Trying the Debayer plugin on a raw MSL image, the following error appeared in the console, and I'm not sure what to do to solve the problem; can anybody help?

bad class file: ZipFileIndexFileObject[D:\CloudStation\Pictures\Fiji.app\java\win64\jdk1.8.0_66\jre\lib\rt.jar(java/lang/Object.class)] class file has wrong version 52.0, should be 50.0 Looks like the program expects version 50.0 rather than the more recent version 52.0 of java. You may be able to download the older version and put it in the correct folder to make the program happy.... (non-expert advise). -------------------- |

Is there a way to do it in PhotoShop (v. CS5, Mac)?

Emily,
The free IRIS package looks like it has a good solution in the form of it's 'Convert a CFA image' command: http://www.astrosurf.com/buil/iris/tutorial3/doc13_us.htm -------------------- |

To be fully compliant with the MMM cameras, apply the 5x5 kernel as described in the SIS, Appendix D.
This works well only with the lossless PDS EDRs. Lossy compressed JPGs result in a color cast. |

Yes! Hadn't tested it myself, so it was somewhat of a stab in the dark ... but I'm glad it worked!

IRIS works for Windows only. Is there something for Mac users?
