The human eye can see 12 exposures of light, while cameras typically only capture 5 exposures set by the user or auto mode, missing details in shadows and highlights. To capture the full range of exposures, the document recommends taking multiple photos of the same scene at different exposures and combining them, either through dedicated HDR software or layering in Photoshop, to produce an image with the same range of tones and details visible to the human eye.

High Dynamic Range Photos
- 4. The human eye can see about 12 different exposures of light:
- 5. But a camera only sees about 5 exposures:
- 6. These 5 exposures are set by you (or the camera’s Auto mode!):
- 7. These 5 exposures are set by you (or the camera’s Auto mode!):
- 8. You can’t pick up the extreme detail in the shadows and highlights:

- 10. Take three photos at different exposures:
- 11. Take two or more photos at different exposures:
- 12. Take two or more photos at different exposures:

- 15. Take two or more photos at different exposures: There is a way to get the same result using a single RAW photo – but that’s for another day
- 20. True HDR needs to use 281 trillion colours (16 bit) To discourage professional photographers using PSE, Adobe limits it to a mere 16 million colours (8 bit)! But luckily it can be faked… GEEK ALERT!
- 21. There’s free (and paid for) software that will do the job for you: HDR Photomatix HDR Fusion …and others …or use layers and blending modes in Photoshop…
