PNLF of all PNe from the e²PN.S survey (black histogram) and its individual fields. The colour-coding of the histograms corresponds to that in Fig. 1. The dashed grey histogram denotes the PNLF from the Surprime-Cam photometry. No completeness corrections have been applied to any of the LFs. The black and grey dotted vertical lines denote the PNLF bright cut-offs corresponding to the distance of M 105 and NGC 3384, respectively.
