RICOH LENS A16 24-85 mm : Details on picture quality modes and image size.

The file size of a still image is determined by a combination of its picture quality mode and image size. There are three picture quality modes depending on the compression ratio used – Normal mode (N), Fine mode (F), and RAW mode (RAW). For a movie, you can select the movie size.

Normal mode (N) An image is compressed higher, then the file size becomes small.
Fine mode (F) An image is compressed lower, then the file size becomes large. This is a higher quality than Normal mode.
RAW mode (RAW) The RAW images are the files recorded as RAW data, that the camera captures but without any image processing in the camera. A JPEG file associated with a DNG file is recorded at the same time. DNG files can be developed and edited in a computer with the application software that is compatible with the DNG file format.
For Windows, the Irodio Photo & Video Studio comes with the package, which allows you to do some simple editing of a DNG file.
For Macintosh, use the software commercially available that supports the DNG format (No software for DNG comes with the package).

Picture Quality Mode and Image Size

The picture quality and image size varies depending on the camera unit attached. The chart below shows in case of GXR with RICOH LENS A16 24-85mm F3.5-F5.5.

Note

Shooting in RAW mode

Although JPEG images have a small file size, the image quality is decreased by compression. RAW images are not compressed. This increases file size, but avoid the loss of picture quality associated with compression.

Some settings cannot be used in RAW mode. See the FAQ below for the details.
