High-dynamic-range imaging (
HDRI or just
HDR) is technique that allow a greater range of luminance between the lightest and darkest areas of an image than current standard digital imaging techniques or photographic methods. This wide dynamic range allows HDR images to more accurately represent the range of intensity levels found in real scenes, ranging from direct sunlight to faint starlight. The two main sources of HDR imagery are computer renderings and merging of multiple photographs, the latter of which in turn are individually referred to as low-dynamic-range (LDR) or standard-dynamic-range (SDR) photographs.
The HDR assignment:
- Find some examples of cool HDR images for your journal.
- Using the exposure compensation mode on your digital camera and take several sets (3 or more) of images of one topic with different exposures (keep your camera steady).
- Take several different landscapes with multiple exposures in different locations.
- Download, print/upload a contact sheet.
- Merge 3+ images into one HDR photo.
- Use Adobe Photoshop to merge together. Then try Photomatix.
- Upload 3 or more of your HDR image to your blog or print and paste into your journal.
