Assignment 4: ‘Lighting Techniques’ Amended

The key issues raised by my tutor were:

  • There were a couple of colour balance issues but nothing too bad. I would revisit the images for colour and texture before printing to make sure your colour balance is correct. At the moment the first colour image has a blue/magenta cast, the second a yellow cast, the first texture image a yellow/green/cyan cast and the last texture image looks a little dark.

I have gone back over my prints and corrected these issues and am much happier with the results.

Colour:

colour black

colour white

 

In both shots, regardless of the colour of backdrop the alterations have made the many different shades of wood much more apparent.

Texture:

texture white

Again this was more of a colour issue, and the alterations have greatly improved the shot.

My camera was producing some very unusual shutter speeds, and this was not in fact a result of my conversions. I have however, revised all speeds to a more understandable display as rightfully suggested by my tutor. (At the time of shooting I was very confused by the readings I was seeing on the LCD screen.) The amendments are:

Colour:

White – 0.1 seconds

Black – 0.6 seconds

Form:

White – 2.5 seconds

Black – 3 seconds

Shape:

White – 0.6 seconds

Black – 0.6 seconds

Texture:

White – 0.4 seconds

Black – 0.6 seconds

Assignment 4: Applying Lighting Techniques

For this assignment I am required to produce a series of images of a subject using either natural light or lighting from a studio type setting. The objective was to demonstrate Form, Texture, Shape and Colour.

Form – How 3 dimensional an object is.

Texture – The surface detail of an object.

Shape – The outline/edges of an object.

Colour – Self explanatory.

I decided on using studio lighting and a photographic cube. The handbook requires that we take 8 images, 2 for each category. I decided to shoot 1 of each on a black backdrop, and one of each on white.

Colour:

colour white

 

F.22, 10/80 sec, ISO 2200.

For this image I used 2 photographic lights – one positioned at the top left of the subject, and a diffused light overhead. I also used the flash on my camera lighting up the subject from the front. The camera flash was also diffused as to not create a strong harsh light – as this would make it difficult to observe the different shades of wood. I felt that in order to demonstrate colour against a white backdrop I required several lights to bring out the multiple colours of wood.

F.36 10/16 sec ISO 2000

Using a black backdrop instantly enabled me to demonstrate colour far easier than with the white backdrop as the subjects colour stands out more. For this shot I used an overhead diffused light, and a diffused flashgun positioned to the left of the subject. (The flashgun was approx 3 feet from subject.) The angle of the camera removes any kind of form, and makes the stripes of colour one of the most obvious factors. By using a secondary light source from the left it renders the right side of the subject in a slight shadow – enhancing the darker parts of wood.

Form:

form white

F.22, 25/10 sec, ISO 100

To demonstrate form I had already decided that I did not want to include the whole object, but rather show form using a section of object and its shadow. The lighting here was fairly straightforward – I used 2 strong photographic lights, positioned at the bottom left of the object. The whole object is not visible, yet you can identify its form from the shadow.

F.36, 30/10 sec, ISO 220

One of the strongest ways to demonstrate form in photography is to include shadows. For this image I used a strong light, positioned very low to the floor and positioned at the top left. The camera is positioned overhead using a tripod.

Shape:

Shape silh

F.36, 10/16 sec, ISO 3200

Fortunately the object I have chosen to use has an extremely distinguishable shape. Demonstrating shape through using its silhouette is extremely striking. To get a vast amount of strong intense light I used 3 lamps positioned in a row behind the backdrop. I decided to put the object on a black surface to enhance the strong contrast of black and white.

shape black

F.36, 10/16 sec, ISO 3200

For this image I practically reversed the technique used above. I used a soft diffused light slightly off centre to the right to create shadow on the left hand side of the object. By  rotating the camera and creating an upside down view it adds some interest to the image, as I was very aware that my object shape may be holding me back somewhat.

Texture:

texture white

F.22, 10/25 sec, ISO 900

For texture I felt that using a part of the object would be best.  As I was only focusing on one section of the object it made it relatively easy to position my lighting. I used 2 diffused lights at the top left and right of the object, and a diffused light positioned behind me – highlighting the almost ‘pimply’ effect on the wood.

texture black

F.36, 10/16 sec, ISO 3200

Again I wanted to focus on the ‘pimples’ within the wood, and also to highlight the many scratches on the object. In order to see the scratch effect I had to use a strong light positioned to the back right of the object. When the light was diffused it resulted in an image much like the one above, the only way I could capture the scratches was to bump up the intensity of the light source. I noticed that the left hand side which is in shadow also demonstrates texture as the scratches are mildly apparent here too.

Conclusion:

This assignment was initially very straightforward. On paper it seemed much simpler than the previous assignment. However, I faced several obstacles:

Firstly – the object. At first I had picked a chunky silver ring but decided to find another object as the surface was metal and reflected too much light and the object was too small. I then settled on the pyramid object. I was in doubt as to whether I should have chosen an object that was more interestingly shaped, and not symmetrical.

Secondly, upon choosing the pyramid I was fully aware that it contained no prominent or bright colours….so how could I demonstrate colour?! After studying my available light sources and reading back through the handbook I realised that the objective was not to use a colourful object, but to bring out any kind of colour within the object. i.e the different shades of cream/light brown/dark brown. So I decided to pursue with my chosen object.

Throughout the past 3 assignments I have struggled to whittle my images down to the number required and have sometimes had to choose between 100 – 150. With that in mind I was very conscious of only taking pictures that I felt were strong enough to be a contender.

This is also the first assignment that I have shot completely in manual mode. Something that at first I was petrified of, but will now be doing at every opportunity.

I would have liked to have experimented with natural light, but as I was doing most of my work during winter evenings this was a bit of a challenge.

I feel that the pictures I have submitted fit the objectives and I am pleased overall with what I have created. I found it challenging using the object I picked, but wanted to push my comfort zone. I have learnt a great deal through doing these exercises but especially the assignment. Lighting is possibly the most important and effective tool of photography, whether it is studio lighting or natural available light.

Assignment 4 preparation

I’ve been so busy with work at the moment that i’m falling behind on the deadline I set for this assignment. I’ve been fretting over a suitable subject that I feel will demonstrate the 4 main characteristics of; shape, form, texture and colour. I spent the last 3 evenings practically ransacking my flat looking for some interesting pieces of ‘junk’ that will make an interesting subject, but no joy.

I decided on using a very interesting labradorite ring. Labradorite has the most interesting shades of blue/green/ when it catches the light, so I thought I was on to a winner! Unfortunately that wasn’t the case. The ring is not a large subject, and I felt that my subject should be bigger so I can experiment more with the lighting. Also, as it is silver the texture/surface is extremely shiny and even the most diffused lighting  resulted in some degree of glare. For now, it’s back to the drawing board to find another subject.
