Selecting the Retrieval Tone Curve (USB controller only)
Images are stored on the controller’s
internal hard drive in 16-bit raw mode
(as though you had selected the “None
14-bit” tone curve in the Tone panel).
When you retrieve the images to the
host computer you choose whether to
keep them in raw mode, or apply a tone
curve, and choose whether you want 8
or 16-bits per channel in the retrieved
file.
None . The image is retrieved and
stored as 16-bits/channel without any
tone curve applied. This is a raw image,
exactly the same as shooting an image
with the “None 14-bit” tone curve. The 8/16-bits radio buttons are set to 16-bits and inactive in this
mode.
Saved with scan . The tone curve in effect when the image was captured is applied to the stored
raw file. Initially the 8 Bits or 16 Bits radio buttons are set to the same setting used to capture the
image. So, if the image was originally shot as an 8-bit per color original, the 8 Bits button will be
selected. You may change this setting by clicking on the desired number of bits per color button, 8
Bits
or 16 Bits, before clicking the Retrieve button.
From tone panel . The image is retrieved and the tone curve currently in effect in the Tone panel is
applied. The default setting will be 8 Bits or 16 Bits per color, depending on the setting of the 16 Bits
button on the Tone panel. Thus, if the Tone panel’s 16 Bits button is highlighted, the 16 Bits radio
button in the File Manager will be checked. You may change this at any time prior to clicking the
Retrieve
button.
This option allows you to change the tone curve to a different one than the original image
capture. This feature allows you to retrieve an image with different tone curves applied, or
to remove any tone curve and retrieve a “raw” image for archival purposes.
DNG . This is a raw image format supported by Adobe. The image will be retrieved in the DNG
format (a variant of TIFF) and when double-clicked will open in Adobe Camera Raw. DNG images
are always retrieved as 16 Bits per color.
