Well, by Tomas' message I understand that if you "cancel" vignetting the input will be unmodified in the output. In nona.txt I read: # Vm vignetting correction mode (default 5): # 0: no vignetting correction # 1: radial vignetting correction (see Va, Vb, Vc, Vd options) # 2: flatfield vignetting correction (see Vf option) # 4: proportional correction: i_new = i / corr. # # default is additive correction: i_new = i + corr so you have to put a Vm0 in a Hugin project file.
Indeed, in your email from the last 28th you tell us that the pto file has lines like: *i w640 h512 f0 v17 Ra0 Rb0 Rc0 Rd0 Re0 Eev0 Er0 Eb0 r0 p-0.82153530183907 y-33.6586917800566 TrX0 TrY0 TrZ0 Tpy0 Tpp0 j0 a0 b0 c0 d0 e0 g0 t0 Va1 Vb0 Vc0 Vd0 Vx0 Vy0 Vm5 n"000_encoded.png"* So change Vm5 to Vm0 and let's see if now the results are what you expect to be. regards Luís Henrique Em qua., 30 de jun. de 2021 às 13:07, Álvaro Huertas < [email protected]> escreveu: > > > El martes, 29 de junio de 2021 a las 17:13:07 UTC+2, T.
