There are two gradient types or settings

 One of the basic techniques is the use of the gradient tool. If you want to ungroup multiple layers, just type Shift-Command-G or Shift-Control-G.. To decrease opacity, just drag the white Opacity Stop. This midpoint can be used to adjust smoothness of the gradient by simply dragging it the left or to the right.You can make your own gradient and add it to the pre-defined gradients by saving it and setting the style scale and angle of your gradient. A gradient tool is used to edit or modify a part or the entire layer of an image.

There are two gradient types or settings, solid and noise. its color fades so you will be able to see the layers below.Different locations for gradient include Adjustment Layer, Fill Layer, Layer Styles Menus and Tool Options Bar. Fading is done by swiping across the pixels.Before you can use the gradient tool, convert first the background layer to a regular layer. Solid is a gradient generated algorithmically, while noise is from RGB values. It is located in the tool bar and there is a window provided to customize your gradient. Choose any gradient style and make sure that the gradient layer is transparent. 

There is also the gradient blending modes for foreground and background colors. If you drag it to the left the smoothness of the gradient is increased and when you drag it to the right the smoothness decreases. Double click the gradient layer and choose new gradient style. Then, create a gradient layer. There is a small diamond that appears between the stop markers called the Gradient Midpoint. You can have your foreground transparent.The Gradient Editor dialog, which can be extracted when you click the gradient itself, is used to modify gradient. The transition between color bands can be determined by adjusting the smoothness. 

Drag the top Opacity Stop if you want to lengthen the opaque portion of the gradient. Just double click the tool bar Gear Powder Metal Parts in the color picker to change the color of the foreground or background. If you want to modify you're your work, use the Gradient Editor.To edit multiple layers, group them first by selecting them and then type Command-G or Control-G.Different gradient shapes include diamond, reflected, linear, etc. Short strokes result to sharper gradient and long strokes result to smoother gradient. Solid gradient is used for manually set colors, while noise is for numerous color bands.There are different ways in eliminating opacity on images
