#Rawtherapee crop image software

Comparing RawTherapee's real neutral image to a pseudo-neutral one from these other programs will expose the differences. Most raw development programs (programs which do read the real raw data instead of just reading the embedded JPEG) apply some processing to it, such as a base tone curve, even at their most neutral settings, thereby making it impossible for users to see the real, untouched contents of their raw photos.It is worth mentioning at this point that if you shoot in 'RAW+JPEG' mode then you could in fact be wasting space on your memory card and gaining nothing for it, as your raw files most likely already contain an embedded JPEG identical to the external one saved in 'RAW+JPEG' mode.

The embedded JPEG image discussed here is stored within the raw file even in just 'RAW' mode! When you open raw files in other software, what you are usually seeing is not the raw data, but the embedded, processed JPEG image! Examples of software which are either incapable of or which in their default settings do not show you the real raw data: IrfanView, XnView, Gwenview, Geeqie, Eye of GNOME, F-Spot, Shotwell, gThumb, etc. Most cameras offer storing photos in one of three modes: 'RAW', 'JPEG', or 'RAW+JPEG'. Some raw files contain as many as three JPEG images differing only in resolution.

When shooting a raw photo, most cameras embed within the raw file a full-resolution JPEG image with tone curves and other adjustments applied.

When your camera (or other raw editing software) processes the raw file it compensates for this by increasing exposure compensation by the same amount. Most cameras also underexpose every photo you take by anywhere from -0.3EV to -1.3EV or more, in order to gain headroom in the highlights. Some cameras, particularly low-end ones and Micro Four-Thirds system, may also apply lens distortion correction to not only fix barrel and pincushion distortion but also to hide dark corners caused by severe vignetting or by the lens hood. Exactly what gets applied depends on the choices made by your camera's engineers and company management, but usually this includes a custom tone curve, saturation boost, sharpening and noise reduction.

Even if you set all the processing features which your camera's firmware allows you to tweak to their neutral, '0' positions, what you see is still not an unprocessed image. It processes the raw image in many ways before presenting you with the histogram and the preview on your camera's display. Your camera does not show you the real raw data when you shoot raw photos.There are three things you must know first to understand what is happening here: In some cases this difference is minute, but in other cases it could be significant - the image could be darker, lack contrast, be less sharp and more noisy. When opening a raw photo you may notice that it looks different from your camera's JPEG, or from what other software show when viewing the same raw photo. When you close the image (which happens automatically if you open a different image or if you close RawTherapee) the current tool settings are automatically saved to a sidecar file as specified in ' Preferences > Image Processing > Processing Profile Handling'.Įek! My Raw Photo Looks Different than the Camera JPEG When opening an image, RawTherapee loads the tool settings from the sidecar file if one exists, else it applies a default sidecar file as specified in ' Preferences > Image Processing > Default Processing Profile'. Note that the effects of some tools are only accurately visible when you are zoomed in to 1:1 (100%) or more these tools are marked in the interface with a '1:1' icon alongside the tool's name. It reflects the adjustments made by the tools in the Toolbox. This preview is generated from raw data if such is available. The central panel shows a preview of the image being edited. 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/VT) which is more memory-efficient and lets you use the Filmstrip (described below). The Image Editor tab is where you tweak your photos. 2.1 Eek! My Raw Photo Looks Different than the Camera JPEG.
