Setting Iso Sensitivity - Epson R-D1s User Manual

JPEG is a universal image format that can be viewed on most computers
without using proprietary software. Files saved in JPEG format are
compressed and smaller than those saved in RAW format. They do lose
varying degrees of picture quality when compressed, and are less
suited for postprocessing because resaving a JPEG file further degrades
its quality. JPEG format is fine for viewing on a regular computer screen
and can also produce good quality prints if saved in a high enough
resolution.
Set the image quality as follows:
1. Pull up and hold the image quality/WB lever at the Q position.
2. Rotate the jog dial to select the desired image quality setting on the
status gauge:
Setting Format
R RAW
H JPEG (High)
N JPEG (Normal)
* 13 MB if RAW+JPEG is selected in the RAW Setting. See page 34
for more information.
3. Release the image quality/WB lever.

Setting ISO Sensitivity

The ISO sensitivity setting determines the camera's sensitivity to
available light. As ISO sensitivity is increased, less light is required to
expose an image, which permits faster shutter speeds. This is helpful
for shooting fast moving subjects without blurring, but it also amplifies
any digital noises caught in an image, which can produce a picture with
a grainy appearance.
To set ISO sensitivity, pull up and rotate the outer ring of the shutter
speed dial to select 200, 400, 800, or 1600.
