Wk 7 - Gel lighting

Gel Lighting

Modern gels are thin sheets of polycarbonate or polyester placed in front of lighting.  Gels have limited life, especially in saturated colours. 

We had three tasks to complete for Gel lighting
  • 1) Create a studio portrait utilizing gels to change the colour of the lighting on the background.  The colour on the subject must be neutral

f8, 1/200, ISO 100
We placed two lights in the background, one had a purple gel and the other had blue gel.  The front light was placed on the side of the subject.  I chose to take off the soft box so that the direct light could shine on to my subjects face.  The photographer before me had taken photos with the soft box and it seemed a bit too dark for my liking.  In photoshop the only thing i did was removed some of the blemishes on her face and neck.
  • 2) Create a studio portrait using gels to change the colour of the lighting on your subject.  Keeping the background neurtral

With this photo we moved the lights in front of the subject.  Not so flattering, but shows us what can be achieved by placing gel lighting directly on the subject.  We also moved a light to the back shining on the background
  • 3) Create a studio portrait using gels to change the colour of the lighting on both the subject and background
Gel lighting example

f5.6, 1/200, ISO 100
With this shot we placed light in front and behind the subject.  The red gel was placed on the light behind and the blue gel was placed on the light at the front of the subject.  As you can see the red gel emitted a strong colour.  This could be because the light behind the subject had a higher output then the light in front of the subject.  As the colours merged, the areas where the red gel was not dominant showed up as purple.  This is present at the back of the subject and in her shadow at the front.  

As an experiment a green gel was placed over the blue gel and a yellow gel was placed on the light behind the subject.  The blue is visible in the subjects shadow and behind her.  A dark green covered the front of the subjects face and body.  The yellow cast rim lighting on the side of the subjects arm. 

Although not the best looking photo, this shot illustrates different effects gels can have on a photo.

Portfolio Wk 6 - presentation ideas

My plan for printing this week has been halted because i have two options in mind.  Last week i was really pushing to get some tests prints done so that i could make a decision on which paper to print on.  The four images i chose were ones that i thought signified the vision of my work.  This is to produce images which showed the nature of my subjects.  An embodiment of their personality, from my perspective.  These four images were strong edits i thought, and captured a side to my subjects well, these came out of a natural flow and connection in the studio.  In terms of paper i have chosen the Hammulher paper, mainly because i like the warm tones that it gives to the black and white images.  I also like the defined details in the textures which elevate the photos when they're viewed up close.  The test printing was valuable because i was able to see the images on the prints, which gives me a better perspective as to how the work will be viewed close up.

I got on the buzz of prese…

Wk 2 Depth of field Artist: Sebastiao Salgado

Sebastiao Salgado Is a Brazillian social documentary photographer and photojournalist.  He started taking photographs in his 30s.  Sebastiao Salgado works on long term, self assigned projects.  He devotes years at a time to document the stories of people and places.  Many of his works have been published as books The Other Americas, Sahel, Workers, Migrations and Genesis.  His most famous pictures are of the gold mine in Brazil called Serra Pelada.

Sebastiao has an amazing body of work.  The images i have chosen showcase how he uses Depth of Field to capture the essence of his subjects.


This is an example of wide depth of field.  As we know wide depth of field focus range covers a large area front-to-back.  Depending on a lens camera range this could be from several yards in front of the focus plane to nearly infinity behind.  These types of photos are often associated with landscapes and architectural photography. It is useful to show a multitude of visual elements or characteristi…
