Task

This week, post 3 photos taken in the theme.  This week: High Dynamic Range! Upload 3 HDRs, not 3 brackets.

Purpose

High: A large quantity
Dynamic: Can be adjusted in real time
Range: The highest and lowest numbers in a set.
Many photo scenarios are impossible to capture in entirety with a single shot. The brilliant sun requires a dark exposure, and the shadowy cave right next to the sun requires a light exposure. However, you can shoot MULTIPLE photos with MULTIPLE exposures (dark, middle, bright). These are called brackets, and measured in Exposure values.
A high dynamic range can be massaged into a “look” also unlocks the full stylistic potential of your Camera Raw files (CR2.) A shot with no lighting design can still be turned into a dazzling and colorful photo.
Also, HDRs can be saved in special 32 bit formats that RETAIN their dynamic qualities. In the same way your eye or camera can be dialed into brighter or darker pictures, a single picture can retain that potency as a .HDR or .EXR. This is a vital part of the game and cinema industry. You can film an actor on a street, shoot an HDR panorama of that spot, and add a CGI robot that’s accurately lit by that environment.

Criteria for Success

Successfully upload 3 HDR images (NOT 3 brackets), either 16 bit tonemaps or 32 bit true HDR images. Winning photos will take advantage of Photoshop’s HDR Pro settings for vibrant colors or true lighting quality that can’t be captured in a single CR2. Save these images as a .EXR, .HDR, or .TIF

Rubric

30 points total.
  • 10 points each for 3 HDR photos.

Knowledge & Skills

In Manual mode, you’ll need to put your camera on the following settings:
  • 2 second timer for the shot time
  • NO AUTO ANYTHING!
  • Use a tripod, or at least have your camera resting on a flat stable surface. That way all 3 photo brackets will be aligned.
  • In the Q menu, go to the setting that looks like -3…..0…..+3 and rotate your camera wheel. This will add extra brackets for a lower and higher exposure

Theme 6: Panorama Submit Assignment Due   Feb 14  by  10:45am   Points   30   Submitting   a website url or a file upload Task Each week, post 6 photos that fit the weekly theme: 3 unedited, and a version of those 3 with edits made in Lightroom or Photoshop.  This week: PANORAMA !   Purpose Panoramas are one of the most jaw-dropping ways to shoot the world around you, but they impose specific technical challenge. Lens choice, stitching software, and learning from your mistakes all play in together for a great panorama.   Criteria for Success Successfully upload TWO panoramas. Since they're made out of a ton of photos, I don't think 3 is needed :P Use jpegs unless otherwise stated in that week’s theme. You can upload your files in a .zip or .7z.

This week's theme: Night photography.  Purpose Night photography brings out some unique challenges. For one thing, it's the ultimate test of your muscle memory! Like a soldier assembling his gun blindfolded, you don't have the luxury of seeing all those camera buttons at night. A good photographer can modify their settings with ease even in pitch darkness.  Second, the total lack of light means uniquely compensating for that with your exposure. If you have a subject (like a person) You might expose them with a flash, followed by a full minute of exposure to get the starry night behind them.  Criteria for Success Your edited and unedited photos will demonstrate 1 or more tec...
