This picture, which was designed by Illustrator, is interesting. The major tool for this picture should be pen tool, and texture effect. The first step may be to create the two hands and the camera. The shape of the hands and the camera are easy to be created by using pen, rectangle and ellipse tools. And then, we can use different colors to make the figures more detailed and clearer. The next step may be to add some wood grain texture to the camera, and another dots texture to the hands and the part of the camera. The last step should be to rotate the whole image.
Yep, several different shape tools to build the camera and lots of use of the pen tool to draw the hands and edit the rectangle that creates the camera. Fill with some textures and color and give it a quick spin with the free transform tool to finish it off.
Oh Yidi, you know the way to my heart. The camera. Yeah total pen tool and some shading. I like the fact that the camera is flipped and distorted. You get lost in a weird circle motion of the image.
