Assignment 4 - Light

Requirement
8 images

Assignment
Pick 1 object. Use any type of light. Produce a small portfolio, showing the following attributes of the object

  • Shape - outline with the minimum of detail visible but isolated from background
  • Form - 3 dimensional properties modelled using shadows and depth
  • Texture - nature of surface using a pattern of small hard shadows (consider level of diffusion and angle of light)
  • Colour - colour of object as strongly as possible
  • Other - object in any other interesting, unusual or attractive lighting

Turkana Man
The Turkana are one of Kenya's minority tribes (800,000 strong). Semi-nomadic, they live in the harsh climate of the north west of the country. They use their animals - goats and camels - as a source of milk and meat. Their god is both the creator of the world and the distributor of blessings. Each day one must seek to find the blessings of life—water, food, livestock, wives, children—in a manner that appeases the ancestral spirits and is in harmony with the peace within the community.

I bought this clay statute of Turkana Man on a visit to Kenya in 1994 to explore a job offer. I didn't take the job, a turning point in my own life and that of my family. Turkana Man has enjoyed the same display spot in our house for nearly 20 years. When I see it, it reminds me of that seminal moment. To everyone else it is just another piece of African tourist art.

Tutor feedback

General comments
Easy to take light for granted, especially when conditions  are unspectacular (e.g. outside golden hour), yet it is the key ingredient that creates atmosphere in photos.

The work shows a good understanding of the brief and controlled use of light. Also, important  to choose a subject that has meaning. 

Key learning points

  • Backgrounds: Whilst the lighting effects are satisfactory, some of the backgrounds are not. Backgrounds affect the quality of the image too
  • Elevation of camera in relation to eyes: Most of the viewpoints are slightly above the bust: potential to make image seem small and even risks condescension (looking down). Take some images from below the eye line. This should make the bust seem more powerful and imposing.
Blog
2 pointers
  • Text is short and technical, perhaps OK for this exercise but you would improve the blog by describing how choice of composition changes the meaning of the portraits
  • Make more connection between Influences - Reaction - Creativity, i.e. your photography reading and the work of photographers - your thinking - your photos.
 


Shape

Side view.
Statue was backlit through a white nylon shower curtain
at an angle acute enough to reveal a small amount of detail 
around the eye, to add interest

One of the best shots. Real silhouette because some of the detail retained. Background isn't distracting in this instance: impression perhaps of being inside a tent.
Rear view.
Figurine was backlit by flash with a yellow plastic  diffuser
over the head and fired through a photo tent.
Setting the flash at a 30 degree angle to the camera 
kept some of the detail at the edge

Worst photo in set! 3 faults: 1. Colour cast detracts from image. 2. Back view is uninteresting. 3. Un-ironed backcloth takes too much attention away from the subject. Replace it. 
However, if you use this image, improve it by: 1. Remove cast in PS, 2. Use Gaussian Blur to disguise the creases on the cloth, 3. Dodge in greater detail in towards the right hand edge (else use a brush at 10% opacity on a 50% Gray layer set at Overlay blending model to paint detail in or out as needed)

Form


Three quarter view.
Bust was inside a photo tent lit by a tungsten lamp 
left (closer) and right to show the contours of the face
Composition delivers brief well. However, background is un-ironed! People will notice. No creases in any professional photographer's portraits.

Front view.
The statute was lit overhead by diffused flash 
supported by a white board reflector (to the left)
against a yellow towel. The shadow around
the high cheek bones givens the image
its depth
Composition also delivers brief but in a different way. Eye contact with front fired flash. Hard shadows around the eyes work well. But: 1. 'Plank' shadow below nose doesn't: use a reflector to raise detail. 2. Backdrop is clearly a domestic towel and this  automatically 'colours' the reading of this image: use a clean, large sheet of white or black paper/ cloth, or perhaps create a background that enhances African culture.

Texture


Side view.
Lit by diffused flash to left with white reflector in front
pointed at right hand side of head. Background is
several layers of polythene wrapped around a cardboard frame.
The relatively hard light reveals the most
significant detail
Raking light reveals texture. Suggestion: remove the necklace, a distraction at the bottom of the frame?

Rear view.
The bust is lit by two tungsten lamps, one left and 
the other right. This throws up the surface
detail, includingthe inscription

Better rear view image than Shape#2 above. Best background: even, no distractions, says nothing!

Colour


Front view.
Filling the frame with the face against a
neutral white background highlights the
mud brown colour of the statue

Framing and focus on eyes work, but effect is slightly soft. Shows terracotta colour well, but remove the fragment of necklace as a distraction.

Front view.
The background of a complementary 
colour, Turquoise (wrapping
paper glued to cardboard sheet), provides
the contrast to reveal the colour of the 
figurine
Colour background is not out of place in an African background. Less confrontational eye contact compared with Colour #1. Even so, blue and terracotta work against each other in a way that a deep red or yellow would not. Consider replacing this image by the last one in this post. 


Images 'on the bench'

These images made the short list but didn't get picked


Shape
More interesting than those selected
but too far away from the assignment instructions
Lens flare would probably be seen as a fault
rather than a mood enhancer

Texture

Print was disappointing
Print was also disappointing

Form

Low lighting creates a tension in image
which I dislike

Colour

Conventional portrait of less
interest than 2 images chosen in this category
A candidate for inclusion in assignment? Works as Form as well as Colour. If so, reduce glare in RAW Conversion by dialing down the highlights.

Photographic Lighting - Shiny Surfaces (4.5e)


Requirement
4 to 10 images

Purpose
To learn how best to shoot objects with shiny to mirror-like surfaces

Technical learning
  • Photographing shiny surfaces, like chrome or silver, present special challenges

Exercise instructions

  • Pick an object with a very shiny surface
  • Place it against a suitable background (e.g. black velvet) on the floor
  • Set up your camera on a tripod (so as to avoid a reflection of the camera on the object)
  • Place a light close to the camera
  • Take a photograph for reference
  • Obtain a large sheet of tracing paper and roll into a cone so that the small end fits around the camera lens and the wider end around the subject (but not visible in the viewfinder)
  • Observe the difference and take a second image
  • Experiment with different (a) lighting positions, (b) distances and (c) camera angles

Images and review
An inheritance from my uncle. Shot in a Photo Tent on a piece of black acrylic and a black card background. Light sources were 2 photo tungsten lamps. 1 lamp stayed in the same position during the 6 shots, at 90 degrees to the camera left. The other lamp was moved into different positions, as described below.


Cufflinks

Photographic Lighting - Concentrating Light (4.5d)

Requirement
Several images

Purpose
To experiment with the effect of concentrating light on the subject and creating shadow around it

Technical learning
  • Concentrating light on part of a scene can be achieved in 3 ways: (a) use a dish reflector with a tungsten lamp or flash unit, (b) fit a snoot to a light source, and (c) block light falling onto the scene (with a black card)
  • You can create a DIY snoot by rolling black card into a conical shape and taping it to a flash unit

Exercise instructions
  • Experiment with concentrating light on a scene using an improvised snoot and black card to block part of the scene

Images and review
Made a DIY snoot from A4 black craft foam rolled into a cylinder around the flash head and held together with duck tape. Cost 51p. Cheapest piece of useful photo gear yet!

Paint pots on garage shelf


Snoot pointed upwards and 45 degrees from
left to create an impression of a high shelf
Odds and ends

Snoot pointed moderately downwards
towards the front of the shelf
to bring the focus onto the metal
tray and its contents
Green Jerry Can


Snoot pointed into mouth of plastic
jerry can to give the plastic a
luminous green glow
as well as show the traces of dried
petrol from use
