Oh boy!
What a topic. First off, Anton "made" U2 like he "made" the looks of so many other bands, Depeche Mode come to my mind but there is also others (Echo and the Bunnymen comes to mind but I'm not sure).
For album art cover, the most profound influence was Vaughan Oliver, who made art covers for the 4AD label which included such acts as Clan of Xymox, Xmal Deutchland, Colorbox, Cocteau Twins but oddly enough, no Dead Can Dance.
But he played with photocopiers.
Besides Corbinj, I don't think that there is any other photographers who made such a lasting impressions. He was the right guy at the right place at the right moment.
Will look into the archives concerning Corbinj, I have an article somewhere
