SPOT THE DIFFERENCE<br />
Forget bit depth, compression algorithms and Bayer demosaicing.<br />
All most of us need to know is how the differences between raw<br />
and JPEG affect the photos we take...<br />

RECOVERING<br />
OVEREXPOSURE<br />
How much of a safety net does<br />
raw provide? Our initial frame<br />
(taken with a Nikon D800 set to<br />
Raw+JPEG) was overexposed by<br />
two stops, which has left the sky<br />
looking washed out. Both JPEG and<br />
raw images were fixed in Camera<br />
Raw by dragging down on the<br />
Exposure slider. While by no means<br />
perfect, the raw image retains<br />
detail in the brightest clouds. JPEG +2 OVEREXPOSURE RAW +2 OVEREXPOSURE<br />

RECOVERING<br />
UNDEREXPOSURE<br />
Teasing detail out of underexposed<br />
shadows isn’t too tricky. Here our<br />
initial exposure was four stops<br />
underexposed, leading to a nearblack<br />
image in all but the brightest<br />
areas. Both raw and JPEG images<br />
were fixed in Camera Raw using the<br />
Exposure slider. Although lifting<br />
underexposure has led to increased<br />
noise in both images, the raw image<br />
holds much finer shadow detail. JPEG -4 UNDEREXPOSURE RAW -4 UNDEREXPOSURE
