brush tool with complete details


Brief introduction of brush tool

 Brush tool is a  painting tool. Click Here!It works like a traditional drawing tool by applying the colour using strokes.Click Here! It’s located in the standard Tool Bar and its default shortcut Click Here! is the letter B.
The Brush Tool works by adding a shaped mark on a layer, and if you continue pressing the mouse button or the pen on a tablet, several marks will be added creating a stroke until you release the pressure. Click Here! The essentials options for the brush tool are: Brush Tip Shape, Blending Mode, Opacity and Flow. Click Here! You must understand those concepts before moving forward with the advanced settings.Click Here!
Photoshop includes several built-in presets, that are in fact pre-made brushes ready to use.


Use Of Brush 

This is the most Click Here! basic option for any Photoshop User, the Brush Tip settings allow you to modify the way to add colours on a Photoshop document using the Brush Tool.Click Here! By clicking on the Brush Preset Picker Click Here! in the default Options Panel you will see several built-in presets. On many of the presets you can easily adjust two very important values:
Master Diameter increases or decreases the size of the brush tip. The default shortcuts to increase or decrease Click Here! are the Left Bracket key and the Right Bracket key respectively. Photoshop CS4 enables a dynamic way of doing it by Ctr + Option (Mac) + Click or Alt + Right Click (Win) and Drag.Click Here!
Hardness increases or decreases the brush tip’s border strength, 0% means a really soft border (colour fades out) and 100% a precise border.Click Here! The shortcuts to increase or decrease hardness percentage are the Left Bracket key and the Right Bracket key respectively. In CS4 you can dynamically modify this value by Ctr + Option + Shift (Mac) + Click or Alt + Shift + Right Click (Win) and Drag.Click Here!
You can even combine Click Here! Foreground and Background colours (we will see this feature forward). Most of the time the colour that is applied by using the brush tip is the Foreground Colour.Click Here!


Picker Contextual Menu/Use

There are Click Here! many useful tools at the Brush Preset Picker menu including Create a New Click Here! Preset, Edit it, and Delete. Then there are some options to Click Here!display the list of brushes in the Preset Picker panel, below there are several examples of this. Besides, you can easily Manage the Brush list by loading, saving and replacing brushes in the list, or Append one of the existing Brush collections. We will see more about preset creation shortly.


Brush Blending Modes

Each time you paint Click Here! something using the Brush Tool you can chose a Blending Mode for the stroke. A Blending Mode is a way to mix the Click Here! colours with the object(s) behind them using several mathematical formula's working over the RGB values of each pixel. Let’s try some of them.Click Here!





Modes: Normal, Dissolve, Behind and Clear

Let’s review some of the basic Blending Modes.
  • The first  Click Here!  on the list is the Normal Mode,  Click Here!  which paints the colour as is without applying any transformation to the colour pixels.
  • The Dissolve Mode adds some noise at the edge of the brush stroke.
  • Behind Mode paints behind  Click Here! an existing stroke even if they are both on the same layer.
  • By using the Clear Mode you can delete a section of an existing stroke.


More Blending Modes

The Following Click Here! Blending modes are just theClick Here! same that can be applied to the Layers, below you can see some examples of blending modes, and some applications. They are fairly useful for adding colour to objects Click Here! (Darken, Multiply, Overlay) or add some lights (Lighten, Colour Dodge). You have a lot to experiment with here, no matter how many years you have been using Photoshop, you never stop learning about Blending Modes.


Opacity

The Opacity Click Here! Value is a percentage of transparency,Click Here! 100% means a full colour stroke, a small percentage means a more transparent painting. Click Here!

3. Flow

The Flow value is a percentage that sets the rate of colour applied. Each time you press the mouse button the amount of colour applied is controlled by the Flow Click Here! percentage, besides it cannot exceed the Opacity percentage unless you click again in the same place.



Brushes Panel

The Brushes Panel is the right place to create, Click Here!edit, save and load a particular brush behaviour or Click Here! Brush Preset. You can customise several things here like the brush tip shape, scattering, opacity jitter, flow jitter, Background/Foreground jitter, configure controls for each variation and more.
To show the Brushes Panel go to Window > Brushes, or press the F5 key. You need to select the Brush Tool on the Tools Panel to enable the Brush Preset options.
As you can see, as soon as you show the Click Here! Brushes Panel you can click over the Brush Presets option on the left and then in the main area a list of all the active brushes. Try them before moving forward in this guide, paint some random strokes using different presets and see what happens. Next we’ll create a Custom Brush, and apply several variations to it.Click Here!

Creating a Brush Tip from an Image

One of the most powerful features of  Photoshop  Click Here! is the ability to create custom brushes from scratch using any image as a source. This time we’ll make a brush using this image of a nice leaf.

Step 1

Open your image in Photoshop, and double-click on the "Background" Layer in the layers palette to make it editable. Then Go to the Channels Click Here! panel (go to Window > Channel) and duplicate any of them (you can duplicate a channel by dragging the layer over the Create New Channel button at the bottom). I’m choosing the Green this time, then hide the other channels for awhile.
Then, With the "Green copy" channel selected hit Command + I to invert the colours, Then adjust the levels a little bit to make the leaf whiter. Finally, hit Command (Ctr) + A to select the entire image, hit command (Ctr) + C to copy the "Green copy" channel to the Click Here! clipboard and then delete it. Remember to turn on the visibility of the RGB channel before moving forward.



Step 2

Go back to the Click Here! Layers Panel, select the only  layer and go to Layer > Layer Mask > Reveal All. Switch to the Channels panel again and select the Layer Mask  Click Here!  channel added at the bottom. There hit Command (Ctr) + V to paste the clipboard, and that’s it. Now go back to the Layers panel to see how it looks.



Step 3

Now add some Click Here! adjustments to the leaf, go Click Here! to Window > Adjustments to show the Adjustments panel. First add a Black and White > High Contrast Red Filter, and then a Levels adjustment using the values shown in the Click Here! image below. Finally, select the three layers, and merge them by Click Here!pressing Command (Ctr) + E.
Then using the Transform Controls, re size and rotate the leaf as you wish, the only restriction is that the image cannot exceed the 2500 by 2500 pixels in size. Finally, Command (Ctr) + Click on the merged Layer miniature to select the leaf contour, and go to Edit > Define Brush Preset, type some name and voila a brand new brush tip ready to customise.Click Here!


Step 4

Once you’ve created the tip Click Here! shape, you will see it in the Brushes Panel. You can select the brand new brush and Click Here! paint some spots to see how it actually looksClick Here!.






Create a Brush Preset

Now we’ll review all Click Here! the possible variations of a brush preset, from the brush tip to colour jitters and pressure controls. The first thing that you should do by creating a Brush preset is select a brush tip from the library or, as in this case, start working Click Here! with a custom brush tip. The Lock icon next to a brush attribute retains the setting even when you change your tip or preset.

Brush Tip Shape

The first thing that you can customise is the brush tip.
  1. The Diameter value is a pixel measured size of the Brush Tip, Click Here!  cannot be bigger than the tip image.
  2. The Flip Axis check boxes flip the tip on its respective axis, X or Y (Horizontally or Vertically) or even both.
  3. The Angle value rotates the brush by the desired degrees.
  4. Roundness defines the elliptical roundness of the brush tip where 100% is a perfect circle.
  5. The Spacing is the percentage of  Click Here!  space between images when you draw a stroke on the canvas, using a mouse or a pen tablet. The larger the percentage, the bigger space between colour spots.
  6. Finally, you can edit the Hardness value  Click Here!  of the tip. Anyway custom Brushes created from an image cannot modify its Hardness value, but it will work with the default round tip for instance. Click Here!


Shape Dynamics

Shape dynamics Click Here! enables several options to handle randomness of Size, Click Here!Angle, Roundness and Flip Axis values.Click Here! The larger the percentage, the more random the result. Every Jitter can be controlled using a proper hardware device like a Graphic Tablet.


Control

Many brush behaviours like Guttering and Click Here! Scattering can be controlled by setting one of the options Click Here! of the Control drop down. There are five Control options that you can use:
  1. Off means no control will be applied.
  2. Fade Control  Click Here!  fades the brush stroke from the initial diameter to the minimum value in a custom number of Steps (i.e. 25 steps in the image below). Click Here!
  3. Pen Pressure  Click Here!  Varies the brush diameter by using the pen pressure values provided by the external device (a graphic tablet). Pen Tilt and Stylus Wheel works the same way but using the hardware’s tilt and stylus wheel values. Click Here!


Scattering

Scattering (1) determines Click Here! the  amount and placement of brush marks in a stroke. The higher the scattering percentage the more distribution of marks. Click Here!The Both Axes check box enables the scattering in both X and Y axis, deselecting Click Here! this option means the scattering will be perpendicular to the stroke direction.
The Count slider (2) specifies the Click Here! number of brush marks, a large number means many marks. Count Jitter (3) adds some Randomness to the amount of marks on a stroke. Remember you can apply the Control Click Here! options for Scatter and Count Jitter as well as in Shape Dynamics.Click Here!



Colour Dynamics

This option Click Here! controls how the colour of paint changes across a stroke. Click Here! The way it works is pretty simple, it just adds some random colour marks in a Click Here!range between both Background and Foreground colours.
  1. The Jitter  Click Here! Percentage defines the randomness between the colours. There you can define a Control for the Jitter, Pen pressure, Fade, Pen Tilt or Stylus Wheel. Click Here!
  2. The Hue Jitter controls  Click Here!  the difference between the Front Colour Hue and the Foreground Colour Hue, the larger the percentage the bigger the difference.
  3. Saturation Jitter defines a percentage by which the Saturation of a stroke varies between Foreground and Background colours,  Click Here!  a larger percentage means a lot of variation of the Saturation.
  4. Brightness Jitter is pretty much the same as the previous, but this works over the Brightness value. A higher percentage means  Click Here! a darker colour increases the difference between front and back colours.
  5. Purity increases or decreases  Click Here!  the saturation of the colour.

Dual Brush

Let’s change the Click Here! brush tip for this one. In theClick Here! following example I’m creating a peculiar brush (1) for an easy explanation of the Dual Brush. This one combines two tips to create a mixed mark. The second brush texture is applied Click Here! within the brush stroke of the primary brush, only the areas where both strokes intersect are painted. You can choose a blending mode to combine the primary tip with Click Here! the second, and all the common brush tips variation shown before.

Texture

Textured brushes Click Here! use a pattern to make strokes look as if they are painted on a textured surface. To paint with a texture, grab one of the textures from the pop-up panel and set a percentage for the pattern Scale. You can Invert the pattern Click Here! colours as well. Let’s review some variations of the ways to use a texture brush.
If the Texture Each Click Here! Tip check box (1) is selected, then each time you paint a mark a new instance of the texture will be applied (consider a brush stroke as many marks). If this is unchecked the texture will remain flowing through the stroke as a whole.Click Here!
The Blending Mode option Click Here! (3) blends the texture with the brush tip colour and Depth (4) will increase or decrease the texture’s contrast creating a depth sensation.
At last some textures enable the Depth Jitter with a variation between Depth and Minimum Depth percentages using a Control (rarely used, but you can experiment with it).




Other Dynamics

There are two Click Here! options here. Opacity Click Here! Jitter adds randomness to each mark’s Opacity, and Flow Jitter will vary the Flow of the stroke. You can add a ControlClick Here! for any of them (Pen Pressure, Fade, Pen Tilt or Stylus Wheel).





More Dynamics

There are five more dynamics on the list:
  1. Noise  Click Here!  will add some noise at the borders of the brush mark.
  2. Wet Edges creates an illusion of watercolour  Click Here! painting, where the borders of the stroke seem darker than the centre.
  3. Airbrush simulates traditional  Click Here!  airbrushing, so a long time pressing the click button means a bigger mark. The Airbrush option corresponds to the Airbrush option in the options bar.
  4. Smoothing, pretty useful wen  Click Here!  you’re painting in a rush, as it produces smoother curves in brush strokes. Great when you’re drawing with a mouse. Click Here!
  5. Finally, Protect  Click Here!  Texture applies the same pattern and scale to all brush presets that have a texture no matter if they have different settings. Click Here!








Create a New Preset Brush

Before or Click Here! after modifying the brush options, you Click Here!can easily save it by going to the Panel Menu and selecting New Brush Preset or clicking over the New Brush Button at the bottom of the Panel. Type a name for it and that’s it!Click Here!
This Brand new brush Click Here! will appear now in the Brushes Panel, but if you reset the brushes library (you’ll see this next) or if there’s a problem Click Here! with the default Photoshop’s Preferences file, your brush will be lost.


Save and Load Brushes Libraries

  1. In order to keep your very own  Click Here! custom brushes you can save as many brush libraries as you want.  Click Here!  Click Save Brushes in the Brushes panel to save the actual set of brushes as an ABR file (you can delete the unnecessary brushes before saving the library by clicking on the Delete icon in the panel). Click Here!
  2. To Load a previously saved  Click Here!  brush library, click on Load Brushes in the Brushes Panel menu, or double-click on the ABR file itself in your file system. Either way will append the library at the bottom of the brushes list active in Photoshop Click Here! .
Besides you can click on  Click Here! Reset Brushes to load the default brushes list, or Replace Brushes to override the active list of brushes with a new one.
