If you want to make a similar effect, but also suffer from no 3D software, how to deal with it? In fact, using Photoshop through a few simple steps is completely achievable. In fact, the following example has a lot of space to expand, this article only describes the most important steps of the operation.
1, a new size of 800x800 px canvas, white background. Use the selection tool "Polygon Lasso" to sketch a shape selection, and then create a new layer and fill the selection with light blue on the layer.
2, according to the diagram operation, to just fill the layer using filter filter>distort>shear, make the initial shape of the tentacles.
3. Use the free transform function (ctrl+t) to adjust the shape of the tentacles in the upper step to the right position. Next, use our favorite airbrush tool to brush out the high light and be light. Many methods, the order is not fixed, of course, brush out the effect is not the same, here on the introduction of a relatively simple one. Activate the selection of the Tentacle shape (hold down CTRL and click on the layer in the Layers window), keep the selection, and place the new layer above the tentacle shape layer. Select the Airbrush tool (in PS7.0, Airbrush has been incorporated into the brush function, I think we can still find it. Brush the high light portion of the tentacles on the layer (the high light color uses white) and, as shown, this step suggests layering, which makes the high light part more hierarchical.
4, the high light part is finished, activates the tentacles shape the constituency, creates the new layer above all high light layer, chooses the 50-100 px the airbrush tool, the color uses the darker blue, brushes the edge dark area along the tentacles selection's two edges, then uses the filter filter>blur> Gaussian Blur, depending on the situation, is mainly to make the dark areas more coherent and soft. As shown in the figure
5, at this time the tentacles have been basically formed, to the shape of the tentacles layer layer effect layer Style>drop shadow, there is more three-dimensional, as shown in the picture.
6, of course, only a single tentacles of the very lack of a sense of level, make a few more to see ...
7, if you do not want to use a light background such as white, and to use such as red blue, then you can remove the tentacles shape layer, you will be surprised to find that your tentacles more sense of three-dimensional.
