 RAW development performed by OM Workspace is called **PC RAW processing** because it is performed by the PC. With some Olympus cameras it is possibile to perform the so called **USB RAW processing**, i.e. the processing is performed by the camera graphic processor (generally the Olympus TruePic) via the USB cable. The camera must be turned on and switched to the **RAW/Control** mode (see the picture of the USB menu on the right). Unfortunately the E-M10 is not capable of such mode. RAW development performed by OM Workspace is called **PC RAW processing** because it is performed by the PC.

 For the Olympus E-M10 the thumbnail embedded into a RAW file is a JPEG file with a resolution of **3200 x 2400** pixels and about **1 Mb** in size (you can extract if using the ''dcraw'' program). For the Olympus E-M10 the thumbnail embedded into a RAW file is a JPEG file with a resolution of **3200 x 2400** pixels and about **1 Mb** in size (you can extract if using the ''dcraw'' program).

 +I made a simple test opening a RAW file and **changing the white balance** from the in-camera preset to //shade//, no other changes were applied to the image. The image is then saved with JPEG quality 98 and //best quality// subsampling. Here it is a 8x zoom detail, compared with the in-camera JPEG. As you can see the **noise reduction** applied in-camera is significantly higher than the one used by RawTherapee:
