Step 1: Set up space
In Aperture go to File>New>Project, name it, then hit OK. Set up your camera close enough to the computer so your USB cable will reach.
Step 2: Start session
When you’re ready to shoot, connect your USB cable to the camera, then the computer, and switch on your camera. Go to File>Tether>Start Session.
Step 3: Tether Settings
In the Tether Settings there are many things that can be changed, or you can just start a session. It’s wise to set Store Files to In the Aperture Library.
Step 4: Customise name
Change Version Name to Custom Name with Index, and type a name. Add Metadata, like your name, to the empty fields. Check the Show HUD box.
Step 5: Select camera
Click Start Session in the bottom- right, and the HUD (heads-up display) will appear. Select your camera from the Camera drop-down at the top of the HUD.
Step 6: Capture images
Click Capture, and your camera will take a picture. Moments later it will appear in Aperture. Keep clicking Capture until you’ve got what you need.
Step 7: Check as you go
Double-click an image to see it full size, and click on the Loupe to examine details close-up. Click Browser in the top-right to go back.
Step 8: Reframing
Reframe the shot and keep pressing Capture until you get exactly what you want. Click on the Loupe to examine details in images without expanding them.
Step 9: Stop Session
When you have everything you need, click Stop Session. If you need to disconnect and start a new session, images will still be captured to this project.
