I do not think that agencies will stop retouching photos. I suspect that they will just indicate "Photographie retouchée" on each picture and that's it. Indeed, while the article talks about a "cigarette-packet style warning", I don't think there is any requirement for the warning to be especially prominent. Here is the relevant decree (in French): https://www.legifrance.gouv.fr/affichTexte.do;jsessionid=15021BB425BFE0E2BEFE43A7D44BC750.tpdila09v_1?cidTexte=JORFTEXT000034580217&dateTexte=&oldAction=rechJO&categorieLien=id&idJO=JORFCONT000034579357 https://www.legifrance.gouv.fr/affichTexte.do;jsessionid=150.... The relevant part is Art. R. 2133-5. It just says that the warning should be "easily readable". I think in practice it will just end up as part of the small print that you already find on many ads.
