On the other hand, the DNG files produced by DNG4PS are about 30 percent
smaller. DNG4PS applies some lossless compression, which the CHDK does
not do—for speed reasons, obviously. But if disk space is an issue, you could
always feed the resulting DNG files into the
Adobe DNG Converter
and
compress them even further! That is actually all the
Adobe DNG Converter
can do for you—in particular, it does not understand the RAW format CRW
produced by the CHDK.
So, yes, I prefer the in-camera creation of DNG files.
4.5.5 In-camera RAW processing
You don’t necessarily need a PC to process RAW files. With the CHDK it is
possible to develop RAW files within the camera. The selected RAW file will
be converted into a JPEG file.
Why should you do this? The advantage is that you can apply some
processing parameters after a shot has been taken, for example
Color
Accent, Color Swap,
one of the choices in
MyColors,
or a different
White
Balance
setting. You can even create different versions from the same RAW
Figure 4-36
The
Settings
dialog of DNG4PS. The
program is able to furnish the resulting
DNG files with the EXIF data found in
the corresponding JPEG files. You must
specify your camera under the tabs
Camera types
and
Camera options
.
