Thumbnails allow you to open depicted images after a double-click that launches toolbar and history panels in the opposite corners separately. This menu has seven pages covering general settings, editing background color, layout, doing image editing, file browsing, color management, batch editing, etc. Just access them with the “Preferences” button located in the upper right. To keep the RawTherapee review concise I will not go over all the seven pages of settings where you fully customize your working space to your particular needs. By default, the last opened directory will be visible after startup. After that, give RawTherapee time to process each file and depict miniatures in the central working window. With the first RawTherapee launch the file viewer tab will remain empty until you specify the location of the RAW photos intended for photo editing. Follow the link to the official webpage, select the version for your operating system, download and install RawTherapee. Unlike Photoshop, Lightroom or Capture One Pro, you don’t need to register to launch the RawTherapee download. It is positioned as software for deep color correction and quick cataloging, but you can also find here some advanced tools from Photoshop. RawTherapee is an open-source cross-platform photo editor.
