In fact, I think the use of 3D software to build a more real water than Photoshop, but here I would like to introduce a very cool technique to make the mist material, I hope it will help you.
1, the establishment of a new file, width of 300pixels, height of 200pixels, the background is black
2, here I first use the shape tool to build water area, click the "U" button, draw a rectangular selection area.
3, select the menu edit>transform>perspective, as shown in the image deformation.
4, the interesting part begins, builds a new layer, this layer will use the brush to add the mist effect. Click the "B" key to select the Brush tool, find the name splatter brush, and select 59pixels as shown on the edge of the rectangle.
5, and then add some blur effect, select Menu Filter>blur>gaussian Blur, set to 8, this will make you brush the edge of the painting with the rectangle very good integration.
6, to build a new layer, use the same steps above, just the color of the brush to choose a lighter color, I use the color for #0099ff, select this bright blue for the foreground color and then increase the brush effect, and then reduce this layer of transparency to 25, good, as shown in the results.
7, on the level board click the Blending properties to open the Layer mixer panel, select Drop Shadow use the default value plus shadow effect, select Bevel Emboss and then set as shown in the figure.
8, the water mist material finishes! How do you compare the effect with the picture? Of course you can also add layers and add different colours to give the water mist a better depth.
Look, is there a tropical coolness in Hawaii that adds such water mist to the picture? Oh, see you next time!
