GeBng to know you
¡ How long have you been taking photos?
¡ What do you like to photograph?
¡ What equipment do you have?
¡ What would you like to learn in this workshop?
3
Metering
¡ What is metering?
¡ Different metering modes: ¡ Matrix ¡ Centre-‐weighted ¡ Spot
4
Focusing
¡ Manual focusing
¡ Auto focusing
¡ Focal point
5
Focal point and metering
¡ The focal point determines/influences the meter reading
¡ SelecIng the area to meter
¡ Locking exposure
¡ SelecIng the focal point
¡ Locking focus
6
Exposure: backlit subjects
7
Two ways to expose the backlit subject ¡ Focus on subject
¡ Lock exposure
¡ Re-‐compose
¡ Take the photo
¡ Recommended:
¡ Use spot metering
¡ Focus on subject
¡ Take the photo
8
Exposure compensaIon
¡ The camera can record a range of tones between pure black and pure white
¡ The histogram shows the tones which are in the photograph
9
Tones: black, grey, white
10
Exposure compensaIon
¡ So, the camera can record a range of tones between pure black and pure white
¡ But, the camera assumes that the subject is mid-‐grey
11
Exposure compensaIon
¡ Accordingly, snow will appear grey, not white ¡ Over-‐expose ( + compensaIon)
¡ And coal will appear grey, not black ¡ Under-‐expose (-‐ compensaIon)
12
Exposure compensaIon
¡ The camera assumes that the subject is mid-‐grey
¡ Early evening sky a^er sunset: deep blue
¡ The camera will overexpose and ‘wash out’ colour ¡ -‐ exposure compensaIon to deepen the sky
13
ISO ¡ SensiIvity of the sensor
¡ 100, 200, 400, 800, 1600 … 12,800 …
¡ ISO, aperture and shufer speed
¡ Shoot at the lowest ISO possible (image quality)
¡ Changing ISO manually
¡ Auto ISO
14
ISO: low light ¡ Greater depth of field = smaller apertures (e.g. f/11, f/16)
¡ Smaller apertures require the shufer to be open for longer
¡ Slower shufer speed increases the risk of hand shake (blurring)
¡ SoluIon?
¡ Increase ISO
¡ Tip: use auto ISO and set minimum shufer speed
¡ Allows photographer to vary aperture (dof) without blur
15
ISO: low light ¡ But!
¡ Higher ISO (e.g. 800, 1600) = ‘noise’
¡ ‘Noise’ is a grainy effect in the image
¡ Tip: use the lowest ISO possible (e.g. 400 rather than 800)
¡ With higher ISO: reduce noise in ediIng
16
ISO: low light
¡ For long exposures
¡ Use a tripod
¡ Set ISO to lowest seBng
¡ Double check ISO is not set to auto!
17
Basic ediIng
¡ File type and size
¡ Exposure
¡ ComposiIon: cropping
¡ So^ware
18
Basic ediIng: File type and size
¡ File type ¡ JPEG and RAW
¡ Shoot the best quality and largest size ¡ RAW ¡ JPEG: Fine and Large ¡ But think about capacity
¡ Save in JPEG original size
19
Basic ediIng: exposure
¡ Recovering clipped areas
¡ Lightening shadows
¡ AdjusIng brightness
¡ Increasing contrast
¡ But remember: don’t go too far!

Basic ediIng: composiIon ¡ Cropping ¡ If the scene or portrait is perfectly composed, no cropping necessary
¡ Fill the frame! ¡ But, we do not always have the luxury of Ime to compose, shoot, review and recompose
¡ Be aware: cropping throws away pixels and reduces prinIng size
