I said you twisted it because you did completely wrong by zooming in LR that is only for viewing purpose but not for photo enlargement. The right way is thru Photoshop Bicubic enlargement.  If you did that correct way you will see the result I showed that is truly untwisted.  I gave the steps that everyone can duplicate.

It's not 'dark magic', it's simply zooming in on the raw data to see what has been recorded.

That is totally wrong way.  As I suggested, try bicubic enlargement in PS.  Again here is 100% cropped between two.  Look how different from yours.  This is the right way to show the real difference.

I'm sorry Peter, but this is just plain wrong.

hehe.  bicubic enlargement in PS is well known the right way in photography world.  You can try bicubic sharper by downsampling 60D files to match to 5D size, lol.  I actually gave 60D a favor by upsampling 5D files.  As someone suggested the best way should be leave at their original size.  However I upsampling 5D files for easier comparison to prevent a delusion that bigger size resolves more details.

If you use any type of enlargement algorithm such as "bicubic sharper" then you are interpolating, or 'inventing', detail that has simply not been recorded by the sensor! LOL!

Check the above link, Bicubic Smoother is for upsampling while Bicubic Sharper is for downsampling.  Anyway photoshop Bicubic enlargement is the best way to enlarge photo while still keep as much details as possible.

Please Peter - stop this rubbish.

If you want to compare which sensor resolves more detail, you can't use a method that interpolates and inserts detail into the image that was not recorded by the sensor.

Try to understand rather than simply arguing all the time!

You are wrong buddy - you need to man up and admit it.

It's becoming clear that he is out of his depth hereand is simply arguing for the sake of arguing.  He is wrong...plain and simple.  Pretty obvious here.
