The image you see in the preview is taken from the working profile's color space and converted into the monitor profile's color space, if a monitor profile is loaded, or into sRGB if one is not. These tools are marked in the interface with a '1:1' icon next to the tool's name.

Note that the effects of some tools are only accurately visible when you are zoomed in to 1:1 (100%) or more. The preview will show you the effect of all the adjustments you make.

This preview is generated from the actual raw data by processing it according to the settings either you manually set, or those that are stored in the processing profile used when opening that photo, as specified in ' Preferences > Image Processing > Default Processing Profile'. The central panel holds a preview of your photo. You can switch to ' Multiple Editor Tabs Mode' (METM) by going to ' Preferences > General > Layout', however each Editor tab will require a specific amount of RAM relative to the image size and the tools you use, and also the Filmstrip is hidden in this mode, so we recommend you first give SETM a try. By default RawTherapee is in ' Single Editor Tab Mode, Vertical Tabs' (SETM) which is more memory-efficient and lets you use the Filmstrip (described below).

The Image Editor tab is where you tweak your photos. 2.3.1 Red, Green, Blue and Luminosity Preview Modes.2.1 Eek! My Raw Photo Looks Different than the Camera JPEG.
