1. DACC Basic Photography Film, filters and digital – Week 3

2. Filters for Black and White Film  Filters in B & W darken opposite colors  Filters in B & W lighten complimentary colors  Filters have a filter factor number to adjust the exposure

3. Filters and Filter Factors  Filter Factor exposure increase similar to stop settings  Yellow filter (K12) – filter factor of 2, increase exposure 1 stop  #15 Orange ff-4 - +2 stops  #25 red ff-8 +3 stops  Green #58 ff-6 - +2.5 stops

4. Filter Effects

6. Real World Examples – Yellow Filter

7. Real World Examples – Red Filter

8. Filters for Color  Filter factor usually less important - -use the ttl meter  Filters for color correction, special effects and reduce reflection  Digital – Camera has built in “White Balances”  Most important filter – the UV filter

9. Polarizing Filter  Generally has a filter factor of 12 = 3.5 stops  Reduces reflection  Adds saturation to color  Also used in B & W

10. Polarizing Filter – Different planes

11. Color Correction – FLD Filter or Florescent White Balance

12. Color Correction for Tungsten - 80A filter

13. Late or early light & shadows - #85 filter or Shade White Balance

14. Close-Up Filters  Usually comes in +1, +2 and +4 magnification  Can be “stacked” for greater magnification  No Exposure compensation needed  Not as Sharp as an true Macro lens

15. Filters for Special Effects  Star Filters  Graduated filters  Prism Filters  Matte Boxes

16. Film  Different Film Speeds  Different Color Balances – Daylight, Tungsten – Type L  Digital Utilizes “White Balance”

17. Films Available  Color Negative C4-1 Process  Fuji, Kodak, Agfa  Films available from 100 to 1600 ASA  E-6 Slide Films  50 to 800 ASA  Slide film processing  Black & White Films  Kodak and Ilford  Films available from 50 ASA to 3200 ASA  Black & White Processing

18. Higher speed – more grain

19. Film Size  Traditional - 110 - 126 - 35mm - 120 - 4x5 - 8x10  Digital - MEGAPIXELS - The more the better!

20. Digital Auto Settings

21. Advanced Modes  P – Program Mode  Tv – Shutter Speed Priority  Av – Aperture Priority  M – Both Shutter and Aperture set manually  A-DEP – An aperture priority where camera sets f-stop according to the subject

22. White Balance Setting Available

23. And then there’s times when you might want to leave the white balance at daylight…

24. Shooting RAW Format  PROS  RAW Format allows to make color corrections in post processing.  RAW Format allows to make incredible corrections to highlights and shadow areas.  CONS  Photos will be huge file sizes – at least 4 times larger.  Need to have RAW converter program  Can be very time consuming
