I am try to model my daughter in 3d what is the best method. Step by step. Specifically modeling/ sculpting the face. How do I use a refrence image the right to get the right proportions.
Well, you’d begin as any sculptor would – by carefully noting the proportions of the head and the placement of features. I had a sculptor friend who routinely used a board with a graph-paper grid on it, and a “selfie-stick like” camera mount opposite. He would place this around a person’s or a figure’s head (or, whatever he was sculpting) and take reference photographs – at a glance he could now see, say, “the nose is 3.75 inches below the top of the head and extends out 1.1 inches.” And, so on. He placed the same grid-frame beside the sculpture as he worked on it. Did very nice work.
In Blender you can of course put a photograph as a “backdrop” behind the modeling screen to use as a reference, but if so you need to take some care that the proportions correspond correctly.
first you need to get use to blender tools
getting photorealist 3D model is very difficult and must be almost an advance user - so need a lot of practice
and Head are so hard to get right in 3D too!
but wish you good lock
