Preparation of photographs

As I forgot to mention this earlier in week one, I am writing down how I prepare my photographs here.
The first step of the head modelling is to take pictures of both front and left view. Use the lens correction under filter to correct the images. Play around with it until I get it straight enough and have symmetry on both sides of the face.

 

At the end, merge two images together and adjust the position with the ruler (see details in the early note).
