![]() To run the PhotoFlow plug-in on this image, go to the "Filters" menu and select "Filters -> PhotoFlow. The starting point is an existing image opened in GIMP. It is therefore possible for example to adjust the luminance of the image without changing the color components, or to adjust the color saturation in a way that is more natural and pleasing than in RGB. This panorama was obtained from the combination of six views, each consisting of three bracketed shots at -1EV, 0EV. To explain my workflow I will use the image below as an example. The goal of this tutorial is to show how to create a sort-of-HDR panoramic image using only Free and Open Source tools. In order to start the GIMP AppImage and let it find and use PhotoFlow for opening the RAW files and/or run as a filter on the existing layer data, open a terminal and type the following: export PHOTOFLOWPATHHOME/Applications/photoflow.AppImage HOME/Applications/gimp. The Lab colorspace (or better CIELab) is an alternative representation of the pixel data that, unlike RGB, separates the luminance information from the color information. Creating panoramas with Hugin and PhotoFlow. One of the possibilities offered by the PhotoFlow GIMP plug-in is to apply non-destructive edits in Lab colorspace to any GIMP layer. Having difficulty playing this video Click here and let us know. This screencast explains the details of how to run the GIMP AppImage and briefly introduces the tools that are provided with it. GIMP - Let A Photo Flow Into The Camera - English. The most simple way to use GIMP in combination with the PhotoFlow plug-in under Linux is to download and run the AppImage package that is hosted on the web site. It means that PhotoFlow can be used directly within GIMP, to open and process RAW images as well as to apply non-destructive editing to any GIMP layer. Every aspect of the RAW processing can at this point be modified and tweaked, or new adjustment layers added to further edit the RAW image.Since a while PhotoFlow is also available in the form of a GIMP plug-in. The plug-in will in this case read the name of the input RAW file as well as the value of all the RAW processing parameters from the meta-data stored in the GIMP image, and will restore the RAW processing in the state as it was when the image was sent to GIMP. Let’s choose for the moment the first option, Edit current. ![]() The file-photoflow plug-in calls the PhotoFlow editor to process. If the configuration meta-data is found in the selected layer, the PhotoFlow filter gives you the choice between starting a new edit (corresponding to the Create new option, in which case the input pixels will be taken from the selected layer and the output will be sent to a new layer above the selected one) or continue editing the current layer (corresponding to the Edit current option, in which case the input pixels will be taken from the layer below the selected one and the output will replace the contents of the selected layer). PhFGimp is a set of plug-ins that allow to invoke the PhotoFlow editor directly from GIMP. What does this mean? When the plug-in sends the pixel data back to GIMP, it also saves the editing configuration as a meta-data blob in the GIMP image structure, so that it can be retrieved when the same layer is edited again with the plug-in. The PhotoFlow interface will open up with two pre-loaded layers, one for loading the RAW image and the second one which applies the RAW processing: Instead of opening the file directly, GIMP will call the PhotoFlow plug-in and pass the file name to it. The loading plug-in is very easy to use: launch GIMP, go to File → Open, select a RAW file from disk and hit the Open button. a filter plug-in that can be used to process a selected layer and output the modified image into a new layer, pretty much like the well known G’MIC plug-in.an image loading plug-in that is used by to open and process RAW images. ![]() PhotoFlow currently provides two types of plug-ins: ![]() The text is still work-in-progress and not yet complete, however I would appreciate any early feedback on what is already written, so that I can tweak the rest of the text according to the comments and suggestions already received… The PhotoFlow GIMP plug-in This topic is intended to be a draft for a blog post or article about the usage of the PhotoFlow GIMP plug-in.
