You can also set the desired intensity value directly in the numerical field near the slider.Īt this point, the sky looks approximately as we would like, however the rest of the image also got darker, which is not what we would like to obtain. Instead of moving the control point up again until you find the best result, it is much easier to tune the overall intensity of the adjustment using the correspoinding slider in the top part of the dialog. The picture will most likely be too dark.

You can also set the control point position precisely by putting the X and Y coordinates in the numerical fields below the graph. In the 'curves' configuration dialog, click on the diagonal line of the 'RGB' curves to create a new control point, and then drag the point downwards like in the screenshot below. Step #3: Darken the image with the 'curves' toolĪt this point we are ready to add a 'Curves' adjustment to selectively darken the sky in the image.Īdd again a new layer, this time selecting the 'Curves' tool in the tool selection dialog (see screenshot below). Press the 'OK' button to confirm the changes and close the dialog. For the moment, we set the name of the layer to 'background' and we make sure that the target channel is set to 'RGB' and the blend mode to 'Passthrough', like in the screenshot below. In this case, since the buffer layer does not do any processing, there are few parameters that can be confgured. When the new layer is created, a configuration dialog is immediately opened in order to set the initial values of the various parameters.

Click OK to confirm and close the dialog. You should get something like in the image below. To add a new layer, you have to click on the '+' button at the bottom of the layer list and choose the desired type of layer in the dialog that pops-up. This type of layer does not perform any processing, and is simply used to define a 'label' to a given point in the editing workflow, so that we can refer to it at a later point. In the next step we will create a 'buffer' layer, which we will call 'background'. Once the image is opened, the first thing we have to do is to change the name of the bottom layer: double-click on the name of the layer ('background' in this case) in the list at the right of the image and change the name to 'landscape 1' as shown below, then press the 'OK' button to close the dialog. src/photoflow $HOME/TestImages/landscape1.tif The one that is used in this tutorial is available here, and is called landscape1.tif.Īssuming that you have followed the instructions for building photoflow from sources (otherwise please see here) and that you extracted the testimages.zip file in your home directory, you can open the landscape1.tif image in photoflow like that: $. The final result will look like this: Step #1: open your imageįirst of all you need to open a suitable image. As the mask will be derived directly from the image itself, the sky adjustment will blend seamlessly with the rest of the image. Here the technique is used to darken the sky in a landscape image, without touching the clouds and the ground. In this tutorial we will see how it is possible to apply selective adjustments using specific color channels as masks. Project maintained by aferrero2707 Hosted on GitHub Pages - Theme by mattgraham Back to main page Sky Enhancement Tutorial To run the PhotoFlow plug-in on this image, go to the 'Filters' menu and select 'Filters -> PhotoFlow.A fully non-destructive photo retouching program providing a complete workflow from RAW image development to printing 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. 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. One of the possibilities offered by the PhotoFlow GIMP plug-in is to apply non-destructive edits in Lab colorspace to any GIMP layer.

This screencast explains the details of how to run the GIMP AppImage and briefly introduces the tools that are provided with it.

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. Since a while PhotoFlow is also available in the form of a GIMP plug-in.
