Dark Frame Subtraction
< Raw parameters < Main Menu
Controls the application of the Dark Frame Subtraction feature of the Camera to a RAW shot.
Dark Frame Subtraction is a function used to reduce the effects of sensor noise when the
exposure time is 1.3 seconds or longer.
•
Auto
–
Performs a DFS on exposures 1.3 seconds or longer.
•
Off
–
Never performs a DFS.
•
On
–
Always performs a DFS.
By always performing a dark-frame subtraction the noise caused by the hot-pixels will be
removed from any image. There will be an increase in processing time.
Only First RAW in Series
Enable [
•
] / Disable [ ]
When shooting in continuous mode, this will only create a RAW
capture for the first image. Subsequent images will not have
RAW captures. This allows rapid continuous shooting.
RAW File in Dir with JPEG
Enable [
•
] / Disable [ ]
Saves RAW files in the same folder as the JPEG files. If disabled
then RAW files are always saved in the 100CANON folder.
RAW File Prefix
[CRW_, SND_, IMG_]
< Raw parameters < Main Menu
CHDK lets you name RAW files with any combination of the standard prefixes IMG_, CRW_,
SND. If you are going to process the RAW files with DNG4PS-2 then setting a prefix of IMG_
will allow DNG4PS-2 to retrieve EXIF data from the accompanying JPEG.
RAW File Extension
[.CRW, .CR2, .THM, .WAV, .JPG]
Set the extension to be used on RAW files, so the files are visible when you connect the camera
via USB. (
See:
Downloading via USB, on
page 46.
)
RAW subtract extension
[.CRW, .CR2, .THM, .WAV, .JPG]
Using more than one extension with the same prefix can cause a problem with USB listing.
