All adjustments are reflected in the history queue and the user can revert any of the changes at any time. A color histogram is also present offering linear and logarithmic scales, and separate R, G, B and L channels. While the image is opened for editing, the user is provided with a preview window with pan and zoom capabilities. The Editor tab is where the user tweaks photos. Alternatively, it can be used to process photos alongside tweaking new ones, if one has a CPU capable of handling the workload. The queue tab allows one to put exporting photos on hold until done adjusting them in the Editor, so that CPU is fully available to the user while tweaking a photo, instead of processing photos while the user is trying to tweak new ones which could result in a sluggish interface. It can be used to apply a profile, or parts of a profile, to a whole selection of photos in one operation. The browser includes 5-star rating, flagging, and an Exif-based filter. The file browser shows photo thumbnails along with a caption of the shooting information metadata.

RawTherapee provides the user with a file browser, a queue, and an image editing tab. Thus, RawTherapee supports all the formats supported by dcraw.Īdditionally, RawTherapee supports the following image formats:

While reading raw files it relies on the dcraw code, but only for parsing formats, not for processing. RawTherapee can work with both raw files from digital cameras and usual images. These adjustments are then applied during the export process.Īll the internal processing is done in a high precision 32-bit floating point engine. Adjustments made by the user are immediately reflected in the preview image, though they are not physically applied to the opened image but the parameters are saved to a separate sidecar file. RawTherapee involves the concept of non-destructive editing, similar to that of some other raw conversion software.
