Gimp: How to Use the Paths Tool, Change the Background and Combine Multiple Images.


In this Gimp Workshop we will see an easy
way how to use the paths tool, and create a nice picture of a fairy under a magnifying glass. The download links for the images are in the description. We will start by going to file, open and then
open the photo of the flowers, which will be our background. Then we go back to file and now to open as
layers. Here we click the image of the magnifier glass. We are asked if we want to convert this image to RGB working space. Click convert. This image is bigger then the flower background, which is our current canvas. Go to the menu bar, click image and hit fit
canvas to layers, so we can see the whole layer of the magnifying glass. Now we go to layer, transparency and hit add alpha channel, so we can add transparency to this layer. Activate the paths tool, zoom in by pressing the Ctrl key and, turning the mouse wheel, and place the first node. We start by making a rough path around the magnifying glass, and will edit this later on. Click the next node. When we press the space bar we can move the image by moving the mouse without clicking. When we let go of the space bar we have the paths tool again. And with Ctrl+Z we can undo the previous action. In this way we go ahead until we are close
to our starting point. Now we hover over the starting point and press the Ctrl key. When the cursor shows a connecting sign, we can click and we have a closed path. In the tool options we click edit and then
we can place new nodes on the path between the previous ones. Each of these nodes we can move and edit. By dragging the handles we can edit that side of the path line. In this way we can make a very precise path, and create smooth curves. Once you get the hang of it, its not so difficult. And in this simple and very precise manner,
we can make our path around the magnifier glass. When the outside edge is done, we click in
the tool options on design, and start clicking nodes on the inside of the magnifier, in the same way as we did the outside. First we roughly make a path. When we are at the starting point, place the
cursor inside this point, and press the Ctrl key, and when we see the connect sign, we click and have our path closed. Then we click on edit again and fine tune
the path by clicking nodes in between the already placed nodes and move and edit them. Here too we can also use the handles. When we are done, we go to view, zoom and click fit image in window. Then go to the tool options and click the
button selection from path. Go to select and click invert. Go back to select and click feather. Feather the selection with 5 pixels and click okay. Go to edit and click clear. Back to select and hit none. And there we have our background simple and precise removed with the paths tool. Activate the scale tool. Click in the image. Lock the little chain icon, so our proportions stay intact when we scale our image. Now make the magnifying glass a bit bigger. By placing the cursor in the little center
circle we can drag, and move the whole layer to where ever we want. I think just outside the center makes a nice
composition. When we feel its okay, we click scale. In the next step we will add a flower under
the magnifying glass. Go to file, open as layers and open the image of the daisy. Select the paths tool again and click in the
tool options on design. Here to we will first make a rough selection. Zoom in and out by pressing the Ctrl key and
turning the mouse wheel. Make sure to place the nodes just inside the edge of the flower. Use Ctrl+Z to undo on or more previous actions. Press the space bar to change the cursor into
the move tool, and move the mouse without clicking. When we have encircled the flower, we place
the cursor on the first node, press the Ctrl key and when we see the connection sign, we click and close the path. Check the edit option. Now we make our nodes in between the already
placed nodes, and edit them so we get smooth curves. Here too we can also use and move the handles. Finished? Go to view, zoom and click fit image in window. Click in the menu bar on layer, then transparency
and here click add alpha chanel. Then we click, in the tool options, selection
from path. Go to select, and click invert, Back to select
and now to feather. Feather the selection with 5 pixels again
and click okay. Go to edit and click clear. Back to select and hit none. Now we click on the green, downwards pointing
arrow in the layers panel, to lower this layer one place in the layers stack, so it is placed under our magnifying glass. Click the move tool, and check the option
move the active layer. The path is no longer visible. Then move the daisy under the magnifying glass. Be sure to place it not to high, so we have
room for our fairy. The size is good as it is. Now it is time for our fairy to make her entrance. Go to file, open as layers, and open the PNG
image of the fairy. Here the back ground already is transparent. As you can see, this layer is exactly where
we want it to be, that is below the magnifier glass and above the daisy. But its of course way to big. Activate the scale tool. Click in the image. Make the fairy layer invisible by clicking
the eye and scale the fairy. Again, when we place the cursor in the little
center circle, we can, by click and drag, move the fairy. Satisfied? Click scale and make the layer visible again. Reduce the opacity to around 30. Then go to the toolbox and activate the eraser
tool. Make the size 30. Then zoom in to the feet and legs of the fairy. Here we are going to erase them so that the
white of the leaves of the daisy becomes visible. Follow the outline of the white leaves which
shine through the daisy. When we have gone to far, we press the Alt
key, and then we can paint some back. When we let go of the Alt key, we can continue erasing. If we are not sure where to erase, we can
make the fairy layer temporarily invisible, to have a good look where the white of the
leaves is. Make the layer visible again. When we think its okay, we make the opacity
of the fairy 100 again click view, zoom, fit image in window, now it really looks as if the fairy is sitting on the daisy. Go to the toolbox and click the crop tool. Check the option fixed aspect ratio and fill
in 16:9. Now crop the image. By click and drag inside the image we can
move the selected area. Then click in one of the corners to apply. By clicking on the little zoom icon in the top right, we can maximize our image. Select the ellipse select tool and make a
round selection exactly on top of the edge of the magnifier glass. By click and drag the handles and or corners,
we can adjust the circle. Go to select and click invert, go to edit
and click clear. Select the daisy layer. Hit edit and then clear, Hit select and here
click none. We have now removed everything that fell outside
the magnifying glass. Make a new layer by clicking on the new layer
icon. Name it reflection and click okay. Hold the shift key down and hit the green upwards
pointing arrow, so this new layer is placed on top of the layer stack. Select the paths tool again, and check the
option design. Click one, two, three nodes on the left side
of the glass, as shown in the video, and place the cursor in the first node again. Press Ctrl and click to close the path. Do more or less the same at the right side
of the glass. Then click the edit option. Now place nodes in between, starting left
on the outside, then the inside, and make soft curves in the long lines of both paths. Do the same on the right side, again first
the outside line. Then we click selection from path. No need to feather this selection. Click on a random tool in the toolbox, so
the path is no longer visible. Go to edit and click fill with background color, which is white. Go to select and click none. Reduce the opacity of this layer so we have
two natural looking reflections in the glass. We are almost there now. Select the flower background layer. Then go to filters, blur and gaussian blur. Make the blur radius 30 and click okay. And there we have it, a fairy who thought
she was hidden in a field of daisys. I hope you have fun with this tutorial. Please like and please subscribe to support
