Les gares métro / RER Masséna (maquette) original : 3400x1200,
réduit 1/4, rogné 

rectilinear 150° (6000x1500); don't know why PT color correction is so
bad. Note the image is blurred on the sides but not distorted (Thales'
theorem!).as you can see by measuring the distances between the quarrels.

Enblend did better, once again.

Il faudra bien que j'achète un pied gradué, un jour...
