Photos require rotation to be used effectivly

Once rotated the pictures need to be adjusted to removed effects created from camera

Right click on layer (background) choose create layer from background.

Adjust settings in pop up box according to requirements and select ok

Filter - distort - spherize

Adjust for lens to create flatter image

Select / highlight one picture

Image - canvas size - make canvas 200 percent width

The files need to be merged into a single file to acquire dual manipulation

Select other image

Ctrl + A = Select all

Ctrl + C = Copy selection

Select image with larger canvas size

Ctrl + V = Paste

This will paste the image automatically as a separate layer

Select the move cursor on the left and move the image to the side

Erase extra background from side picture to allow for better visibility using erase tool on appropriate layer

Highlight required areas of picture with area selection tool

Image - crop

Will remove unnecessary background information form pictures and allow easier to manage work space

Take side view picture

Opacity 60% - 70%

Move over forward facing picture

Ctrl + T = Transform mode

Move cursor away from corner of box until rotation icon appears

rotate until aligned best as possible key positions i.e. eye levels

View - show rulers

Move mouse onto ruler (top of work area)

Drag down horizontal guide line to help line up faces

Adjust side face using transform tool until pictures are aligned

(Holding shift while using transform allows scale to be preserved)

Only one half of face is required as final results will be replicated to other side

These blue lines will be used as geometry guidelines

Create new layer

Change colour palette to red

Select brush adjust accordingly

Begin to draw geometry

Geometry refers to polygons

Polygons for 3Ds max topology works bests as quads (four sided 2 dimensional objects)

Task is to cover face in connected quads which follow contours of face

Use guides as aids however do not need to be followed exactly

Below is images of start middle and end of process

Personal preference
Overlayed geometry using straight lines to make sure all geometry lined up + make visualisation easier

Remove older rough version visibility for import
