How to Convert a 2D picture to a 3D Lenticular Print using PSDto3D?

In this example, an image to be processed is a picture of a hot air balloon image, has a clear three-dimensional sense, suitable for stereoscopic processing.

Open the original image in Photoshop. Check the image size. It may need to be modified for the resolution of 75.55 × 8 = 604.4lpi. In this example the document size is very small, so the document size is adjusted for high 6cm, width 8cm, then the size of the image data.

Mark the images of various parts of the stratification. It is divided into 8 layers.

Separate those marked parts.Use the pen tool to do the image matting. Each balloon is selected, then cut; click on button on the lower right corner to create a new layer, and then paste those clipped layers to a new layer.See the picture of original image after separating one layer. Separate other layers according to the process above. Eventually all the layers are separated to the corresponding layer.The clipped part is separated into a new layer, as shown in figure 1.6.

After all the layers are laid, the background will be incomplete. Because in the 3d stereo image, each layer in stereoscopic display will be of left and right displacement. Therefore, in the background, the blank area will be displayed. It is not reasonable, so it needs to complement the blank area.   The method to complement graph is to use the rubber stamp tool. Paste the other similar image to the blank area. In this way, the viewer would not see the unreasonable blank graph, even if the layer has displacement.

Save as PSD format, ready for further process by Psdto3D .

Post processing for stereo image

Import the image above (PSD format) into Psdto3D software.The grating and a lens are not consistent with the actual data. Upon the determination, the actual raster resolution is 75.55lpi, so the grating will be changed into 75.55lpi, lens will be replaced in 8, focus and depth keep the same.WH.performance.mark('step1_rendered');

Set the displacement value for each layer . When the above settings are adjusted, a displacement will be automatically generated. You can adjust a little as per the effect.

Hook line for each single layer. Preview the single layer after each end of hooking line for every layer.

After each layer being hooked line, observe effects combining with the preview, and make adjustment to achieve a desired effect. Preview the results.

Output the final three-dimensional image.

Now, we have finished the process of 2D to 3D conversion. Output the image to a paper, covered with the grating, and you can achieve the stereo sense on the vision.
