So I have seen lots of people, via the internet, shooting tethered. What is that? Well, here's what it looks like.
Forgive the quick and dirty (GIMP'd) image on the laptop.
What happens is the image you shoot goes directly to a file on your computer almost instantly after taking the shot. This seems to be especially useful for portraits... it is a controlled environment, and you want to ensure you have a well lit, sharply focused shot.
The benefit is that the computer screen gives you a larger viewing area than your LCD on the back of your camera and a more accurate idea of what this end-product really looks like. In addition, your subjects can then come over to the computer and actually see what you have shot as well.
I want to try this with a load of portraits at the ward party this weekend.
So how do you do it?
Well, I use Bridge and a Mac. As I was reading yesterday, it appeared that I needed system 10.5. But after a trial with my 10.4 system at home... it works flawless.
Set your camera (on Nikon it is in the Set up menu; down to USB; select PTP (there are 2 options on mine... one is mass storage and the other PTP).
Plug in your camera via USB to your computer.
Then open Automator which is found in Applications folder. You will need to download this little file which allows your computer to see grab those files from the camera and it will put them in your picture folder.
Open Bridge and select to view the picture folder.
You will see the pictures come onto the screen as you shoot. So cool!
By the way, it still stores the pictures on your camera as well as sending them to the computer instantly and automatically.
If you use Lightroom
If you use Aperture
Sorry, I didn't include PC usage, but I have read that it is equally possible with Windows
