·         Class Schedule Handed out – Check out Head on Exhibit in Sydney

Head On Photo Festival, is the world's second largest festival. Now in its third year, it features a wide range of photography across all genres with over 150 events at 100 venues. The 2011 festival was a resounding success for everyone who participated: galleries and other venues, photographers, Head On partners and the viewing public. The festival was opened by Mark Tedeschi QC and attracted widespread media coverage.

Events are spread across Sydney from the CBD extending, north, south, east and west. Aside from traditional venues such as art galleries and museums, exhibitions and events were set in less formal venues such as cafes, pubs and Centennial Park. Most events are free of charge and include indoors and outdoors exhibitions, workshops, artists’ talks, open studios and a 2 day seminar. With the diverse range of venues, events and photography, Head On Photo Festival offered something for everyone.

At the heart of the festival is Head On Portrait Prize which is the nation’s major innovative showcase for Australian portrait photography, reflecting a diverse cross-section of new and traditional photographic practices. It is the most critically acclaimed photographic portrait competition in Australia.

With the launch of the inaugural Head On Photo Festival in May 2010, the vibrant and cosmopolitan global city of Sydney finally gained a photography festival. Sydney is now firmly placed on the global photography scene alongside Perth, Brisbane and Ballarat who all have established festivals.

·         History – Camera Controls – Exposure

·         330BC Aristotle wrote of the suns image projected through a hole in a subject

·         1000AD Alhazen creates the Pin hole camera – camera obscura

·         1267 Roger Bacon writes about the Camera Obscura

·         1490 Leonardo Da Vinci describes a Camera Obscura in detail

·         1558 Giovani Battista della Porta suggests the camera obscura’s use as a drawing aid, he installs a mirror and lens making it sharper and brighter

·         Check out Alex Hogg’s pin hole camera on facebook

·         There is a camera obscura located at the national museum, which is a great way to help you understand the process

·         David Hockney’s book on the camera obscura is a great one to read

·         The first “photo” of camera image was taken by Neipce and it was an 8 hour exposure

·         Aperture is the hole or opening, different sized apertures vary the exposure

·         Shutter is the beginning and end of an exposure – focal plane shutter or Behind the lens or leaf shutter

·         Diaphragm is a mechanism

·         Aperture – hole or opening

·         F.  – size of the opening

·         F number – is the number representing the size of the opening

·         F.16 RULE

ISO 100

Aperture f.16                                                     = perfect exposure on a sunny day

Shutter 1/125  

·         Large f number – small aperture – less light

·         Small f number – large aperture – more light

·         Typical Range – 1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32

1 x 1.4

5.6 – 4 = 2 as much light

5.6 – 8 = half as much light

·         Shutter is a mechanism

·         Shutter speed = length of time

·         1/60 = 60 on the camera

·         Typical Range – 1, 2, 4, 8, 15, 30, 60, 125, 250, 500

·         Each step changes the exposure by a factor of 2

·         Exposure = total amount of light captured exposure can also be used in place of the word photograph

·         Exposure = time (shutter speed) x intensity (aperture)

·         Research Assignment handed out

·         DP review or call/email your favourite photographer to help you choose a lens

·         Introduction – Why this lens, Rationale, I chose this lens because of this this photographers work ect

·         What are the functions, why does a low aperture suit your photography?

·         Include a photo of the lens and photos it can take

·         5 prices call and haggle the price – 2^nd hand and new prices

·         Buy the reference book from CIT

·         10-12 point size

·         REFERENCE YOUR PICTURES

·         TASK FOR TODAY

·         6 images to begin – in pairs take your first 3 photos of the other person as such

·         Correctly exposed 5.6

·         Over exposed 4                                   keep your shutter speed the same change your aperture

·         Under exposed 8

·         Next 3 images

·         Correctly exposed 125

·         Over exposed 60                              keep your aperture the same change your shutter

·         Under exposed

·         Record your results and blog them with a small amount of technical info underneath

This image taken at f5 1/80 ISO800 is over exposed

This image taken at f8 1/80 ISO800 is exposed correctly

This image taken at f11 1/80 ISO800 is under exposed

This image taken at f8 1/80 ISO800 is exposed correctly

This image taken at f8 1/125 ISO800 is under exposed

 

This image taken at f8 1/30 ISO800 is over exposed

This image is back lit

This image is front on lit (creates a flat look)

This image has only a small amount of light present on the right hand side, making most of her face in shadow

This image is nicely lit with the light come on an angle and nicely lighting her face giving it a shapely look

Some other pictures i took

Ten Questions Task

Question One: What are the two ways exposure is controlled? And what are some other factors that play a role in exposure?

Shutter Speed and Aperture

ISO and White Balance

Question Two: You have an ISO of 400, a shutter speed of 1/125^th second and an f-stop of F5.6. a) I ask you to open up the aperture to let more light in by 2 stops. What would you change your reading to?

b) Now, back at your original setting, close down three stops. What is your setting now?

a) to open up my aperture by 2 stops from f5.6 I would stop down to 2.8.

b) if I closed down three stops from f5.6 I would be at f16

Question Three: What are three ways you can measure exposure?

matrix metering / evaluative metering: metering for the sum of the image, and the strength of light in many areas in the viewfinder.

enter-weighted metering: uses the center focal point to measure the amount of light needed to best expose that part of the image. The size of measurement, often made in millimeters can be set in the menu of your camera. You can choose a broader area to meter, or make the meter a very fine point – like 8mm diameter – which to measure. It will disregard the strength of light in other parts of the image and expose only for the part in the center.

Spot metering: a precise, small area of light measurement, used to target the strength of light on a specific part of the image. On most dSLRs it measures exposure where you place the focal point. There is no need to focus and recompose (which is bad habit if you work in shallow apertures!). Spot metering requires you to know and understand Ansel Adams’ Zone System.

Question Four: If in a given situation ‘correct’ exposure is achieved by using 125 @ f8 at ISO 100, indicate the new shutter speeds required to provide ‘correct’ exposure for the other ISO settings below.

Film Shutter speed Lens aperture

ISO400 f8  - 30

ISO200 f8  - 60

ISO100 f8  - 125

ISO50 f8  - 250

ISO25 f8  - 500

Question Five: If in a given situation ‘correct’ exposure is achieved by using 125 @ f8
at ISO 100, indicate the new f-number required to provide ‘correct’
exposure for the other ISO settings below.

Film Shutter speed Lens aperture

ISO400 125 – f4

ISO200 125 – f5.6

ISO100 125 - f8

ISO50 125 – f11

ISO25 125 – f16

Question Six: When you use a high ISO you get image degradation. With film this is called increasing the size of the grain. With digital we don’t refer to grain, we refer to …………………………………….

Grain is referred to as noise in the digital world

Question Seven: On your camera, what is the difference between AUTO mode and MANUAL mode?

In Auto mode the camera registers the light and makes the decisions for you, in manual mode the photographer makes all the decisions regarding the exposure.

Question Eight: All in-camera meters try to render the scene as a mid-tone. So if the mid-toned scene is rendered appropriately, what will happen to the light toned scene (white)? And the dark toned scene (black)?

Question Nine: What type of metering do built-in camera meters use?

Question Ten: If you are using ISO200 how more light sensitive will your exposure be if you change this to ISO400? (HINT: This is equivalent to 1 stop)

If you change your ISO from 200 to 400 your camera becomes 1 stop more light sensitive.
