  • Getting Started with HDR Photography

    1. 1. Getting Started With HDRPhotographyStanton Champion@spchampionspchampion@gmail.comflickr.com/spchampion500px.com/spchampionstantonchampion.com
    2. 2. HDR = High Dynamic Range
    3. 3. Why High Dynamic Range Your camera captures a range of light for an exposure, but it has limits If your subject is outside this limited light range, your camera can’t capture it
    4. 4. HDR Compresses the Dynamic RangeTake several photos and use software to compress the dynamic range so that it can be displayed or printed
    5. 5. What Do You Need?You: Basic knowledge of photography  Controlling Exposure  Shutter  ISO  Aperture  Histogram An Imagination
    6. 6. What Do You Need?Digital Camera: Anything with manual exposure control RAW support is preferable (but not required)  JPGs are not ideal for HDR, but usable in a pinch Exposure bracketing is nice to have
    7. 7. What Do You Need?Software: HDR software  Photomatix (most popular)  HDR Efex Pro  Photoshop  Topaz Adjust A DAM like Lightroom, Aperture, or Capture One is very helpful Photoshop is very nice to have for post-editing
    8. 8. Take 1* or more photos of a subject * - Yes, you can do HDR with just 1 photo. Topaz Adjust is a great tool for this. theo0023 on Flickr
    9. 9. Typically, take 3 – 7 photos of the same scene Each photo has a different exposure Minimize camera movement between exposures
    10. 10. Why take more exposures?HDR narrows the dynamic rangeHistograms get shifted & stretched, for better or for worseMore Data & More Range = Cleaner Results
    11. 11. Avoid movement in the framebetween or during your exposuresMovement can create an effect called “ghosting” which is often unattractive Bandit Queen on Flickr
    12. 12. EditingDownload the photos from your camera  Tagging  CategorizationDo not edit and crop yet
    13. 13. Editing Apply Lens Correction and Noise Reduction to all photos Need the photos to be similar for HDR transformation Do not apply any other edits!  Cropping  Sharpening  Color tweaking  Cleanup  Etc.
    14. 14. Export to HDR ApplicationConvert to TIFF and import all photos into your HDR app
    15. 15. And Then… So Many Controls Photomatix can be a bit daunting… Trial & Error can yield compelling effects The right answer is the one that expresses your creative vision!
    16. 16. Use Available Presets Try different presets to learn the controls Great way to artistically explore a photo
    17. 17. More Help Getting StartedProcess controls the HDR develop mode  Tone Mapping can be more surreal  Exposure Fusion is a little tamer
    18. 18. In Tonemap mode… More or Less HDR Effect Scene Contrast Makes the Lighting Surreal
    19. 19. Cleanup AfterwardsUse Photoshop to Cleanup Remove ghosting Remove HDR artifactsNow You Can Edit: Cropping Color Tweaking Noise Reduction Sharpening
    20. 20. Stuff to Avoid – NoiseHDR can take darker areas and brighten them, revealing a lot of noiseNoise is the devil  Get to know noise reduction software  Shoot at low ISO
    21. 21. Stuff to Avoid – Halos Don’t push contrast so much that dark objects develop “halos” against bright backgrounds AdamSelwood on Flickr
    22. 22. Stuff to Avoid – Contrast Inversion Bright stuff becomes dark & dark stuff becomes bright Sunlit clouds are darker than the stonesAlexandre Buisse & Luminous Landscape
    23. 23. Resources – Stuck in CustomsTrey Ratcliff  Full time HDR photographer  Fantastic HDR tutorialshttp://www.stuckincustoms.com/
