In photoshop shape dynamic is again and again missing
If you are drawing with brushes.
With the exception of the pen tool, the brush tool is the most versatile tool in Adobe Photoshop's arsenal. There are a multitude of tasks for which you can use the brush tool. including retouching, freehand drawing and stamping. However, in order to truly exhaust the brush tool's potential, you need to understand how to change your brush style, import brushes into your toolbox and make your own brushes.
Changing Your Brush's Size and Shape b> To change your brush's and shape, press the F5 key on your keyboard to open up the brush window. A number of pre-formatted brushes will appear, along with a menu of options you can use to customize your brush. Choose the brush that best fits your preference by clicking on its display square on the right-hand of the brush window. Use the sliding bar under the heading "Master Diameter" to increase or decrease your brush's . You can further change the texture, shape or dynamics, or further stylize your brush, by checking any of the boxes in the brush window's tip shape menu on the left. b> Importing Brushes b> You can download custom brushes from the Internet in variety of styles and shapes. To load a brush set you have downloaded, select the brush tool in the basic toolbar and click the small arrow next to the brush indicator at the top of the screen. Click the arrow next to the indicator to open the brush menu. Choose "Load Brushes." When the file selector opens, choose your new brush file--brush files will always have an .abr extension--and click "Load." Your new brush set will be added to your brush palette. Creating Your Own Brushes b> Before creating your own brush, you need to have an image or freehand drawing that will serve as the basis for your brush. Brushes can be simple or incredibly detailed depending on the image used to create them. To make your brush, open the file containing its design. To make the best brush possible, it may be necessary to tweak the file. If you are using a color image, convert the image to grayscale by choosing the "Image" drop-down menu from the top of the screen and choosing "Mode" and "Grayscale." Select "OK" to discard the color information. Continue to tweak the image by choosing the "Image" drop-down menu again and selecting "Adjustments" and then "Levels." Using the slider bar at the bottom of the screen, adjust the settings until you achieve an image that has a sharp contrast between its black and white portions. Once you are happy with the image, choose the "Edit" drop-down menu from the top menu and "Define Brush Preset." Name the brush in the pop-up window that appears. You can now use your brush and further customize its shape and style by using the basic brush preset manager at the top of the screen. Hope this helps.
