Photomatix Pro 2.2 Help 13

IX - Working in 16-bit mode

16-bit mode refers to image files coded with 16 bits per color channel, i.e. 48 bits per pixel for an RGB

image. Most methods and tools of Photomatix work in 16-bit mode, the two exceptions being the "H&S

- Intensive" combination and the cropping tool.

In addition to combining differently exposed images, Photomatix also offers two tools that process

single 16-bit images.

Tone Mapping available under menu HDRI

48-bit Compression available under menu Utilities

The Tone Mapping tool gives the strongest enhancement of local contrast. However, enhancement of

local details in the shadows often increases noise. The 48-bit Compression tool boosts the shadows

details without the associated noise.

To ensure a low noise level, we recommend exposing for the shadows when taking the RAW image,

i.e. to overexpose your shot. Even though the histogram of your camera may indicate that your

highlights will be lost, you should still be able to recover them during RAW conversion -- unless the

dynamic range of your scene is too high, but then a single RAW will not be sufficient and you would

need to bracket in this case.
