In the simulation of X‐ray section topographs by the means of a computer some problems occur concerning the representation of the photographic image. The grey scales used in the case of electron microscopy may not be applied to the case of X‐ray topographs. We have studied a new grey scale and we have adapted the levels of intensity to the specific case of X‐rays. Experimental and theoretical results are in good agreement but it is shown that quantitative measurements on photographic plates may be quite delicate.
