RawTherapee Portable Photoshop Software

RawTherapee Portable is a complex and feature-rich software utility designed specifically in order to help you process raw images directly from your digital camera.

Installation is not a prerequisite, as this is the portable counterpart of RawTherapee. You can easily copy the program files to any location on the hard disk and run the tool from there, by simply clicking the executable. Aside from that, you can drop the aforementioned files to a USB flash drive and use RawTherapee Portable on any computer you have access to.


It is important to mention here that the Windows registry and Start menu/screen are not going to be altered by this app.

The straightforward interface is comprised of a folder structure, a tabbed panel from which to choose the image editing tools, and a preview window.

You can save pictures to PNG, JPG, and TIF formats with different compression values, modify the exposure levels, highlight reconstruction, enable shadows and highlights, adjust the light, contrast, and chromaticity.

You can tinker with the image and edge sharpness, micro and simple contrast, simple and impulse noise reduction, RGB curves (Red, Green, Blue), vibrancy, channels, and HSV. There are also simple options, such as cropping, resizing, rotating, and distorting photos.

When you finish editing, all you need to do in order to save the picture to your hard drive is to choose the output folder and click the “Start Processing” button.
