A method of producing information from at least one camera image of an object comprising the steps: A) recording raw image data of the at least one camera image, B) evaluating the raw image data of the at least one camera image in a plurality of evaluation steps (401, 402, 403), wherein in at least one of the plurality of evaluation steps (401, 402, 403) the raw image data of the at least one camera image or image data derived from the raw image data of the at least one camera image are processed by means of a mathematical linkage with each other in such a way that combination image data are produced, C) deriving the information from the combination image data, D) outputting the information, E) determining (200, 210) an actual measure for a data quality of the raw image data of at least one camera image prior to or after at least one of the plurality of evaluation steps in step B), F) determining (300, 310) a deviation between the actual measure for the data quality and a target measure for the data quality of the raw image data of at least one camera image, and G) again recording all raw image data of those camera images, for which the deviation determined in step F) is greater than a predetermined threshold value and again performing at least one evaluation step from step B) and steps C) to F) either until the deviation determined in step F) for the raw image data of all camera images from the plurality of camera images is less than the threshold value or until a predetermined termination condition is fulfilled, wherein the method is a holographic method, characterised in that the method includes the step illuminating the object with electromagnetic radiation with exactly one discrete wavelength or a plurality of discrete wavelengths, wherein the combination data represent a holographic image and the produced information includes a spatial phase distribution of the electromagnetic radiation of precisely one respective wavelength or a spatial distribution of a synthetic phase of the electromagnetic radiation with the plurality of discrete wavelengths, that is at least reflected or scattered by the object, and wherein the actual measure for the data quality of the raw image data is selected from a group which comprises parameters of a phase shift operation on the combination data, a correlation between the combination data of the object and the combination data of a reference object and an average amplitude of the combination data, a contrast of a known structure of the object in the combination data.
