DESCRIPTION1st lesson The Art of Night Photography, George Brown College, summer 2012
<ul><li> 1. Night and Low Light Photography TeacherPaul Ti l l</li></ul> <p> 2. 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 doesnt work with night photography. 3. 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. 4. 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. 5. Course Outcomes36. Understand their toolbox and what is available to help them for night and low light photography egImage 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. 6. How is night different from day3 Less Light3 Different directions of light3 Mixed light (different colours)3 And perhaps most importantof all 7. HIGH CONTRAST3 Often (but not always)3 Brighter highlights3 Darker shadows3 Light sources in photo 8. So less light means3 Slower shutter speeds (keepthose hands steady)3 Wider apertures (carefulyouve got it in focus)3 Higher ISOs (could be lots ofnoise and sometimes its notas nice as film grain) 9. Shutter SpeedsThe briefer the exposure the less the..3 blurring from subject motionand3 the blurring from our shakeyhands 10. The longer the focal length ofthe lens 3 The more problem our shakey hands cause 11. Hand held exposures3 For Dx sensors1/(focal legnthX1.5)=exposure timeExample 1/(200mmX1.5)=1/300second For full frame sensors1/focal legnth)=exposure timeExample 1/200mm=1/200 second 12. But VR (vubration reduction)3 Will allow you to hand hold for2-4 times as long3For a full frame camera with a 200mm lens 1/100 sec to 1/50sec3Doesnt do a thing for subject motion 13. 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 14. Stopping Motion3 A good guide but it depends onhow close to you are to the object.3 The closer it is the faster it goes3 (Its about degrees per second notk.p.h.) 15. Techniques for holding camera steady.3 Stop3 Hold camera with both hands3 Breath out and squeeze the shutterrelease3 Brace hands and body against solidobject3 Put camera against solid object3 A tripod 16. Surpise Quiz3 The faster some thing goes3 The longer the shutter speed(slowshutter speed)3 The shorter the shutter speed(fastshutter speed) 17. F stops start making sense3 F stops3 Are fractions.3f 2 is really1/2 and f4 is really 1/43 Thats why f 4 is a smaller hole than f 23 But the bigger the number the biggerthe depth of field 18. ISO3 400 ISO is twice as sensitive as200 ISO3 But the bigger the ISO the biggerthe noise3 And the less the resolution 19. So different colours oflight mean3 Do I set the colour temperature orlet the camera do its auto thing3 The colour is probably going to beweird in a part of the picture3 Maybe I can fix it in thecomputer.3 There is a answer but first 20. High contrast means3 Might clip the highlights(do itas little as you can really justfor bright lights in the picture)3 I think its better to clip theshadows(were used to notseeing really dark things) 21. Expose for thehighlights3 Check the histogram3 And 22. SHOOT RAW3 Keeps every bit of goodnessthe sensor caughtand 23. And3 And bracket3 If its a static subject we can do aHDR (high dynamic range) photo-a photograph which is made up ofthe two or more differentexposures of the same subject. 24. What do we photographat night3 Well um, night3 The way things look at night(maybe things we dont usuallythink of as night photographysubjects-flowers, swimming pools,birds, statues, parks,supermarkets, rain, thunderstorms,ice cream (my daughter Alicesidea) 25. Things we make happen at nightLight trails, light painting,multiple flash, long exposures,the motion of things 26. And things that mostly happen at night3 Live concerts3 Buskers3 Sports3 CNE and Theme parks3 Neon3 Restuarants and Clubs 27. Night of Dread3 The annual Halloween paradefrom Dufferin Grove Park 28. Winter PanoramasIllustrating some very mixed light sources 29. Live Music3 Illustrating the challenges andcharms of different venues</p>
