Bayer pattern for Canon EOS 60Da

[dayers]

I have a new 60Da and I have been unable to find out what bayer pattern it uses. Can anyone help me out?

Thanks,

Dave

While I can't answer the question, why don't you take a normal picture (street, tree, flower, ...) and try the different debayering patterns that PI has? It should not take more than 3 tries to find out.

Good suggestion. I assume that the difference using various patterns will be obvious. I will report back and hopefully save other the need to do this.

If you are debayering "fits" files, check the orientation of the image. If you are using the "bottom-left" convention for the origin of coordinates of these files, debayering will throw wrong results.

pretty sure it's the same as all other canon cameras. RGGB if i'm not mistaken. and carlos is right, if the fits reader direction is backwards to the way the fits was written, it will never debayer properly.

You are right, it is RGGB. I sheepishly must report that the answer has been before my very eyes. When an image is loaded, the Process Console has a line, "Filter pattern: RGGB".

Now my question for you guys is how can I know if it doesn't debayer properly?

Thanks for all your help.

How will you know? The tone will be all wrong for nebulae and the stars will be pinkish or greenish. Just use the ScreenTransferFunction.

I have a 60d which pretty much is the same camera except for the infrared filter i believe, I have taken earthbound images which i then loaded the raw images into pixinsight which automatically debayered with RGGB. I compared the colours to the real world subject colours and they were correct hope this helps.

Thanks to all for your help and observations. It turns out that what got me off track was not knowing that I had to edit preferences for Format Explorer > DSLR_RAW to check the Create RAW Bayer CFA box to let me load my .CR2 images correctly. From that point it became pretty obvious at which point images should be debayered, i.e., when ready to go from Gray to RGB.

And just for the record, the bayer pattern is in fact RGGB for the Canon EOS 60Da, as Gary stated.
