Saniya (a dietitian) came in for a new headshot recently.
(Note: I'm aware we prefer the 'hair part' open to the camera-side, client wanted this angle after reviewing shots early on, so we shot most of the session this way).

1) Shot on an APS-C camera (Fujifilm XPro 3 + 56mm f.12 --> ~85mm full frame equivalent).

2) Monitor calibrated with datacolor Spyder.

3) 2x 1x4 length Godox fl150rs + an Apurture light below camera.
