    Night and low light 3 Night and low light 3 Presentation Transcript

    • Night and Low Light Photography Teacher Paul Ti l l
    • Course Outcomes31. Pre-visualize a photograph with multiple light sources at night after learning, from their own experience gained during the field trips, what does and doesn’t work with night photography.
    • Course Outcomes32. Choose exciting locations based on their gained knowledge of the vast subject matter suitable for night work.33. Use photographic equipment at night with confidence.
    • Course Outcomes34. Work with fundamental night flash techniques such as rear curtain and slow exposure flash35. Choose the proper ISO, exposure time, and aperture to create the image of choice, leading to an individual style and working method.
    • Course Outcomes36. Understand their toolbox and what is available to help them for night and low light photography eg Image Stabilization and the very high ISO ratings available. Be able to make appropriate equipment choices based on knowing the state of the art as it stand right now.
    • How is night different from day3 Less Light3 Different directions of light3 Mixed light (different colours)3 And perhaps most important of all…
    • HIGH CONTRAST3 Often (but not always)3 Brighter highlights3 Darker shadows3 Light sources in photo
    • So less light means3 Slower shutter speeds (keep those hands steady)3 Wider apertures (careful you’ve got it in focus)3 Higher ISOs (could be lots of noise and sometimes it’s not as nice as film grain)
    • Shutter SpeedsThe briefer the exposure the less the..3 blurring from subject motion and3 the blurring from our shakey hands
    • The longer the focal length of the lens 3 The more problem our shakey hands cause
    • Hand held exposures3 For Dx sensors1/(focal legnthX1.5)=exposure timeExample 1/(200mmX1.5)=1/300 second For full frame sensors1/focal legnth)=exposure timeExample 1/200mm=1/200 second
    • But VR (vubration reduction)3 Will allow you to hand hold for 2-4 times as long 3For a full frame camera with a 200mm lens 1/100 sec to 1/50sec 3Doesn’t do a thing for subject motion
    • Stopping Motion3 1/10000 will stop streaming water into individual drops3 1/8000 will stop most any motion3 1/4000 high enough speed to take pictures while walking/ and freeze baseballs ie. 90mph3 1/2000 will stop most motion3 1/1000 will stop bicyclists and runners3 1/500 will freeze a person jumping in the air ie. basketball3 1/250 will stop some motion
    • Stopping Motion3 A good guide but it depends on how close to you are to the object.3 The closer it is the faster it goes3 (It’s about degrees per second not k.p.h.)
    • Techniques for holding camera steady.3 Stop3 Hold camera with both hands3 Breath out and squeeze the shutter release3 Brace hands and body against solid object3 Put camera against solid object3 A tripod
    • Surpise Quiz3 The faster some thing goes3 The longer the shutter speed(slow shutter speed)3 The shorter the shutter speed(fast shutter speed)
    • F stops start making sense3 F stops3 Are fractions.3 f 2 is really1/2 and f4 is really 1/43 That’s why f 4 is a smaller hole than f 23 But the bigger the number the bigger the depth of field
    • ISO3 400 ISO is twice as sensitive as 200 ISO3 But the bigger the ISO the bigger the noise3 And the less the resolution
    • So different colours of light mean3 Do I set the colour temperature or let the camera do it’s auto thing3 The colour is probably going to be weird in a part of the picture3 Maybe I can fix it in the computer….3 There is a answer but first
    • High contrast means3 Might clip the highlights(do it as little as you can really just for bright lights in the picture)3 I think it’s better to clip the shadows(we’re used to not seeing really dark things)
    • Expose for the highlights3 Check the histogram3 And
    • SHOOT RAW3 Keeps every bit of goodness the sensor caughtand
    • And3 And bracket3 If it’s a static subject we can do a HDR (high dynamic range) photo- a photograph which is made up of the two or more different exposures of the same subject.
    • What do we photograph at night3 Well um, night3 The way things look at night (maybe things we don’t usually think of as night photography subjects-flowers, swimming pools, birds, statues, parks, supermarkets, rain, thunderstorms, ice cream (my daughter Alice’s idea)
    • Things we make happen at nightLight trails, light painting,multiple flash, long exposures,the motion of things
    • And things that mostly happen at night3 Live concerts3 Buskers3 Sports3 CNE and Theme parks3 Neon3 Restuarants and Clubs
    • Night of Dread3 The annual Hallowe’en parade from Dufferin Grove Park
    • Winter PanoramasIllustrating some very mixed light sources
    • Live Music3 Illustrating the challenges and charms of different venues
