# Converting to a single cel

This section shows you how to convert a single Photoshop 2.5 file to a 3DO cel. Photoshop 2.0 files are also supported. Photoshop grayscale files of any type are not currently supported.

Warning: Converting a file to an uncoded 16-bit cel can cause the program to crash. Choose another cel type.

Follow these steps:

1. Launch Photoshop and open the desired file.

2. Scale or resize to a reasonable size. The standard NTSC screen size, 320 x 240 pixels, is recommended, but a cel can be larger.

3. If necessary, change the file to RGB color.

4. Save the file in Photoshop 2.5 format.

5. Launch 3DO PostPro.

6. From the File menu, select Open and open the desired file. A Document window appears for the selected file.

7. Select Convert to from the Document menu, then pull right and select 3DO cel from the submenu, (see Figure 1).

   Note: The Convert to 3DO Texture option is not currently supported.

8. Select the options for the cel type you want from the Photoshop to Cel dialog, and Click OK. Figure 2 shows the settings for a coded-6 cel.

9. Type the name for the file in the Save As dialog. Using a .cel extension is helpful for future reference. The file is saved as a 3DO cel file.

10. Drag the Document Proxy from the Document window onto the Workbench.

The cel is displayed (see Figure 3).
