Lesson #10. How to draw a Metal Tubes And Wires

Create a new image, 250x250 pixels. As the main background color choose a dark gray. Now create a new layer and with the Pen tool or Paintbrush draw a line form the desired width 15 pixels.
Such a curve, I think, not difficult to draw. Should look as shown.
Call the layer "Wire"

Make a copy layer Wire by dragging its icon on the New Layer button (New Layer). Rename the new layer in the "Cut Wire".

Now hide the layer Wire, clicking on the icon in the Layers panel on the eyes (Layers). This layer is useful to us later.

Now select the Eraser tool (Eraser), define the size of the brush within 5 pixels, and with it will give the type of curve shown in the figure.

Hold Ctrl, click on the invisible layer of Wire in the Layers panel.

Thus to create a selection, not taking into account the transparency of the layer "Wire".

We move then to the panel channels and a Save selection as channel - button.

Our next step is to rename the new Channel in the "Wire Bevel". Done!

Apply to the Channel "Wire Bevel" filter Gaussian Blur (Filter > Blur > Gaussian Blur) with the option Radius first 9 pixels, and then 6, then 3 pixels, and finally 1 pixel.

Apply now to release AutoLevels, Ctrl + Shift + L, and look what happened. ... We are almost done.

Let's get back to the panel layers, and while holding Ctrl click on the layer "Cut Wire", to select its transparency. Then again, turn to the panel Channels, click on the channel "Wire Bevel", press D, to reset the color, inverse the selection using the keyboard shortcut Ctrl + Shift + I, and in the end, Clear selection, press Del.

Remove the selection - Ctrl + D.

Let's go back to the panel "layers" and will make the active layer "Cut Wire".

Then open the dialog box Lightning Effects (Filter > Render > Lighting Effects).

Now - the main thing. Create a white Directional light from top to bottom - from the upper right corner - as shown in the picture. Then, create a blue light directed towards the bottom up - from the bottom left.

Define the following parameters:
Gloss: 100 Shiny
Material: -100 Plastic
Exposure: 39
Ambience: -21

Setup Texture Channel to the position of "Wire Bevel" and determine its height of 15.

Now set the direction of illumination in such a way as to achieve the most desired effect.
Finally, make visible the layer "Wire". Once again, click on it, hold Ctrl, to make the selection.

To make a line of 1 pixel is thinner, inverse the selection - Ctrl + Shift + I, then go to Select> Modify> Expand, enter a value of 1 pixel, Clear Selection - Del and remove it using Ctrl + D.
And the last step: Filter> Render> Lighting Effects.

Setup Texture Channel on the Wire Transparency.

Click OK, added at the discretion of Shadow (Drop Shadow), and all - ready!

Highlight the desired contour, fill the blue color (Shift + F5). Increase the radius of the allocation of [Select> Modify> Expand] to six pixels.

Create a new layer and fill the existing allocation of its white color (Shift + F5). Add noise [Filter> Noise> Add Noise] with values:
Amount: 280
Distribution: uniform
Monochromatic: checked

Photoshop Lesson #8: Detalisation

With the help of selection you need to create a region for work. Fill the selected area with any color that you want. I choose a light brown color.

In order to give your selection some depth, use a dark airbrush and gently shadow the one side of selected area. Use a light airbrush and enlight the other side.

Now choose any texture that you want from your own collection, and apply it on top. Set the transparency to 50-60%.

I'm usually create a new layer and then draw a set of thin lines and blur them, so they add a vintage-look to image. Then I start to shadow their edges with the help of dark airbrush tool.

That's how it looks like after using dark airbrush tool.

Now, simply combine layers and duplicate the resulting layer. You'll probably need to do a little bit more work on the image, but it should look something like this.

Photoshop Lesson #7: How to draw a silver ring

Create a new image (width and height must be multiples of two in fact you'll see why. Also you should change the image mode to RGB). Fill the background in black. Now take the ruler markers at the top and left and place them in the center of the image. You should get a cross in the picture. Create a new layer.

Select "Elliptical Marquee tool", and then move your mouse above the place where the lines cross. Press and hold ALT + SHIFT keys, and then create a circle. Fill it with gray color. Repeat this, but make a second circle a slightly smaller diameter. Now, press DEL to cut the smaller diameter. Cancel the selection by pressing CTRL-D. You result should be a gray ring.

Press CTRL key and click on the layer where the ring is located. This step will mark up filled region of the ring. Go to [Select> Save selection]. Leave it settings default and click "ok". With the selected ring, go to the "Channels" and create a new channel. Leave the channel name default too. Fill the selected area in white, and deselect the choice(CTRL-D). Now you'll need to apply a blur filter [Filter> Blur> Guassian blur]. At the first pass use the filter 4, then 3 and then then 2.

Now go back to layer with a ring. Go to [Select> Load selection] to load the previously selected area. Go to [Filter> Render> Lighting effects]. In the "Texture channel", select your blur channel (it usually has a name "Alfa 2"). Other settigs are:
Intensity: 35
Focus: 69
Gloss: 69
Material: 69
Exposure: 0
Ambience: 8
Height: 80

In order to smooth the edges of your ring, press the CTRL-key and click on this layer in Layers list. Go to [Select> modify> Contract]. Select 1, and then click OK. Now invert the selection and press the DEL-key. You can also remove the "cross" because you don't need it anymore. Go to [Image> Adjust> Curves]. In order to get a realistic "silver effect" set the curves as shown on the picture below:

Now we need to add some color to our ring. Go to [Image> Adjust> Hue / Saturation]. For example a light yellow tint will create the effect of golden ring. This how-to can be used to create not only rings.
