Thanks for your usage of this app, here is steps to use this app.

 I also developed another app which can hide your preview screen, and generate a fake screen when you take picture or video with your camera; you can search the key word "silent spy camera" or check with this website http://myspycamera.appspot.com or send email to me if you want this app.

1. After you install PrivateCamera, and open it first time, there will be an introduction page to introduce our program, you can start this app to take pictures, and all your picture will be stored in sdcard/Pictures/my_camera/, and you also can hide other data, and all other data will be stored in sdcard/Pictures/my_others/

2. After read the introduction page, you can open the app and set your password, Notice if you have not set any password, any body can peek your pictures, so DO set a password, otherwise you do not need this APP :).

3. Then you can take your picture by pressing with the "center button" or "camera button" or "enter button" or press the camera button in this app's screen if you have no keyboard.

4. And after taking picture, all the picture will be stored in sdcard/my_camera/ with fake picture like below:

5. How to get your original picture? Enter the PrivateCamera, and press MENU, and use "Export your private image", then all your original picture will be shown in sdcard/Pictures/my_camera:

6. Notice: Please "Hide your private picture" after you export them.

7. You also can hide your other data with "Protect other data"
