I have made a tiled tiff image and i was thinking about using it for converting raw data to A3 600X600Dpi images using jpeg compression. In the tiff specification it said that tiled tiffs are ideal for large dpi images using jpeg compression.

I think the comment points to the fact that for images that are natural targets for the

JPEG compression method, tiled TIFF files may be better suited.

Take your average photograph: A rectangle (tile) of pixels in the middle of the sky,

the sea, the grass, a wall, etc. contains a lot of redundancy, given that all the pixels

are of very similar color.

A strip, covering the scene from the left end to the right one, will be less uniform.
