A Portrait - preparation and planning

I thought I would use the photography in this assignment to improve and learn from the previous projects. Reviewing my learning log again, I noted a number of things that I should aim to do better:-
- In the first project, some of the photos were underexposed. In others, the light was too hard and bright so that the shadows on the face were unattractive. I need to look more carefully at the lighting when using natural daylight.
-  The photographs that I took in October for the Experimenting with Light project look repetitive as the model is looking directly at the lens in every shot. I need to ensure variety so that the model's head is turning slightly away from the lens.
- Some sense of depth in the background, such as the angle of a wall or perspective lines can add to a portrait (may not be necessary to have a narrow angle like Irving Penn's studio portraits).
- Looking again at Chris Markers image in the style of Leonardo Da Vinci, I noticed the hand position of the Mona Lisa. This could be worth trying for similar head and torso or full body portraits.
The objective of this assignment is to produce 5-7 different portraits of the same person from different photographic sessions. I asked my wife to be my model again as this made it easier to accommodate the different photographic session.
My intention was to take portraits in some combination of the following:-

• Formal poses (sitting/standing) and casual poses
• High key and dark & shadowy
• Active or contemplative moods
• Front lit, side lit and back lit
• Facing front, profile, and intermediate head positions
• Close cropped, head and torso, full length etc. 

For this purpose, I had noted several potential locations:-

• I thought I would revisit G-Live Concert Hall as the external walls provide a suitable background. I hoped to improve on the photos that I took at this location in October when the sun was too bright. As the weather is very cold, my wife would be wearing coat, scarf, hat etc which would be good for some full length and head and torso poses.
• I thought I would take some daylight photos in our lounge at home. This would be good for casual poses, maybe seated on a settee or on the floor. Also possibly for dark and shadowy head and shoulders.
• A friend from the Guildford Photography Society has a small studio set up at his home. I arranged to use this for an afternoon, with a view to using the adaptability of photographic lighting. I hoped to use the studio lights to obtain some high key and some shadowy portraits.
• After looking again at Simon Bremner's photograph at the Taylor Wessing exhibition, I thought of going with my wife to a modern cafe in Guildford. This has plain white walls and natural lighting which should be ideal for photography.  

Whilst I had these options in my mind, I left is reasonably open which type of portrait I would take at each location.
