That depends on how much you are willing to take the camera apart.
If you didn't want to touch it, then you would have to use a solenoid to push the button. That would probably need some drive electronics similar to driving a motor.
If you can take the camera apart then you could replace the switch with a relay. Small relays can be driven directly from a microcontroller. The switch may be more complex than just one switch. Maybe a half-press focuses and a full-press takes the picture. So you might need more than one relay, or maybe one relay with more than one pole. You wont know until you look.
Almost certainly, the switch drives a voltage input (or more than one) on a microcontroller in the camera. So if you traced the signal back you should be able to drive that voltage input directly from your microcontroller. You may have to get into some very small surface mount components.
To remotely trigger your digital camera using a remote camera trigger, you need to connect the remote trigger to your camera and then press the button on the remote trigger to take a photo from a distance. This allows you to capture images without physically touching the camera.
Digital cameras can be operated remotely using a remote control by connecting the remote control to the camera through wireless technology, such as infrared or Bluetooth. The remote control sends signals to the camera to trigger functions like taking a photo or adjusting settings without physically touching the camera.

You can remotely trigger a camera flash by using a remote trigger device that connects to your camera and flash unit wirelessly. This device allows you to activate the flash from a distance, without physically pressing the camera's shutter button.
For a Canon digital camera, a 50mm camera lens is just about right. You can also use other lenses depending on what kind of digital camera you are using.
Answering "How do you transfer photos from a digital camera to your email in box using a USB connection from camera to shared computer?"
Film Camera is the correct answer.
If you are using the Sony Cyber-shot, it just means Digital Still Camera!
