    newby question

    I've a somewhat dated text on digital images, in spanish, and it states that one determinant of pixel quality is "exactitude geometrica" translated as geometric precision or exactness. Help, What does this refer to? Thanks for any help, jondavid

    Possibly zooming in very large on your computer screen then checking for any 'duff pixels' ?

    This one had me beat for a second, and I was thinking there was something lost in the translation from Spanish - so I did a little digging, and found this:

    "Geometrical Accuracy

    Geometrical or spatial accuracy is related to the number of pixel locations on the sensor and the ability of the lens to match the sensor resolution. Interpolation will not improve geometrical accuracy as it cannot create what was not captured."

    Hope that helps?!?!?

    'Duff' usually means no good

    It is possible to get some pixels which are 'dead' or 'hot' and don't work properly. Not usually a problem if just the odd one but could be noticeable if there was a larger cluster.
