Re: X-Trans is NOT Random
In reply to rattymouse, Sep 9, 2012

As a mathematician who spent years studying randomness I can verify that it is not random! It is actually upsetting to see companies abusing the use of these terms.

The only thing I would say is that randomness is related to complexity (in some advanced theories) so maybe they mean that it is a bit more complex to process?

BTW, I do not understand the rude reply from another member of the forum. Completely unnecessary. Rattymouse have you upset people in the past and now they shoot for no reason?

Fujifilm keeps reffering to the X-Trans sensor's layout as random. For example:

"The unique random arrangement of the [X-Tran's] colour filter array is also highly effective in enhancing noise separation in high-sensitivity photography."

This is nonsense. Anyone who looks at the X-Trans sensor can see that it is made up of a repeating/ pattern of RGB. In other worse, if you see one unit (pixel) of the sensor, you can "draw" the whole sensor, over and over and over again. If the sensor were truly random, you would not know what the next unit would look like. The X-Trans is not at all random, it just has a different layout than the Bayer pattern.
