We will use at least two images to complete this lesson. One is an image of the item that you want to tie into a knot (in our case, a nail), and the second will act as a template for tying.
Place both images in one document. Lower Opacity (opacity) layer with a node of up to 60% (can be more or less – depends on the template), so that you can clearly see the layer with the node, and with a nail. Resize the layer with the knot, rotate and place it so that one end of the rope coincides with the nail leg. I marked this area with red lines.
Highlight a nail using your favorite way (Quick mask – quick mask, Pen – pen tool, even Lasso– lasso will be quite suitable for such a simple selection), copy it to a new layer. Slightly push the nail to the side, so that it was more convenient to work with him.
Cut the top of the selected nail and place it so that it coincides with the top of the rope on the template. Tip: we’ll still use this layer with a nail separated from the background, so it’s best to use the function “Copy selection to new layer” (Copy selection to new layer “(Cmd + J / CTRL + J). Thus, you will leave the layer with the nail separated from the background untouched so that you can still cut out of it.
Take a small piece of the nail and place it over the rope. With the tool Deformation (Warp) adjust the nail so that it repeats the shape of the rope – pull the markers and the grid in the direction of the rope. There are three things to remember:
1) Light source. You must add shadows later, but don’t complicate your work. Turn the illuminated side of the nail to the light source, placing its parts along the contour of the knot.
2) Use small nail pieces. The deformation tool is fantastic, but you will make the work much easier (and get the best result) if you use small pieces without distorting them.
3) When you deform a rectangular area (a piece of nail), it is better to start from a horizontal or vertical direction than a diagonal one. Then the markers in the corners will be on a piece of nail during deformation, and not somewhere in space.
Continue this process until you finish the entire node. I was not worried about mixing colors and textures at the junction of the pieces and masking the floors, but I always remembered about the source of light.
It’s time to mask the areas where one piece of nail overlaps another. You can turn off the visibility of the nail layer to access the node layer, which indicates where the docking is taking place. Left-click on the thumbnail of the layer with the CMD / CTRL key held down to select all the pixels on this layer. So it will be easier to mask unnecessary pieces in the necessary places. I marked the overlapping areas in red.
With the tool Magnifier (Zoom Tool) zoom in on the area where the nail pieces are connected to each other. To make the joints invisible, use Stamp (Clone Stamp), Treatment brush(Healing brush tool) and Eraser(Eraser). Since the texture of the nail is not very different in different places, it will be enough to use a soft Eraser, but sometimes you may need to use the Stamp and the Curing brush to achieve the best result.
If you were following the light source during the work, as I warned you, you will notice an area at the top of the node where the lighted side of the nail turns into a darkened one a little unsuccessfully, making it difficult to work with Eraser, Stamped and The treatment brush.
Instead of dealing with cloning tools, you can simply copy a new piece of nail and place it directly on top of another segment, turning the illuminated side upside down (look at the image below, it’s clear what is hard to explain in words).
Apply a gradient mask to a new layer to make a beautiful, smooth transition from one side to the other. You can also use this technique if there are still areas that are difficult to correct using cloning tools.
When all the joints are fixed, you still need to add some shadows to create the illusion that the nail is actually twisted into a knot. If a patterned node is lit like a nail, you can use it to navigate where to place the shadows. I have marked several areas where you need to add shadows. You can use both Dimmer (Burn tool) and dark Brush(Brush) with low Opacity (opacity).
Now hide all layers and use the tool. Stamp(Clone tool) to remove the real nail from the original image. Do not forget to leave the root with which to connect the node.
All that remains is to turn on the visibility of the layer with the nail tied in a knot, and turn off the layers with the original knot and the cut nail from which we took the sections for the knot. Connect the knotted nail with the remaining base and adjust the junction. The robot is ready.
