Wk 1 - Bulb Function

Bulb function

is a shutter speed setting which allows for long exposure times (wikipedia).  This function is used when there is not enough light available, such as shooting at night.  When taking photos at night the shutter needs to open longer.

Bulb function task:
Take three photos at 3", 6" and 8" - with your subject moving out of the shot 3/4 of the way through or stand in the shot. It took us a few takes to get this right - especially as it was hard to see her.

These shots were taken outside at night.  Here are some of our pictures taken with the help of my model Pela

Shutter speed: 3.0", f/22

I asked Pela to walk through this photo after 1 second - you can see her shoes 
at the bottom of the shot

Shutter speed: 6.0", f/22
Pela walked through this photo after 3 seconds


Shutter speed 8.0, f/22


I asked Pela to take a step every 2 seconds


Shutter speed 7.0", f/22

Pela started walking through after 3 seconds, 
you can see her figure as well as her shoes at the bottom of the photo
ore time is equivalent to more light, so when you lack light, you can almost always compensate by keeping the shutter open longer. - See more at: http://www.digital-photo-secrets.com/tip/1293/what-is-bulb-mode-where-is-it-used/#sthash.W0aDgO67.dpuf

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…
