Can I use the vibration reduction on my lens when shooting in fully automatic?

I have a nikon D60 and a 18-105 mm lens. By shooting in automatic I mean fully both on camera and lens.

Added (1). I'm shooting friends wedding and I'm a nervous wreck so i know there will be camera shake.

Added (2). I'm doing this a a favour for a friend who would otherwise have no photograhy. I'm an hobby photographer who mainly shoots animals and landscapes. So this is change.

Yes. Use it only when needed, as it drains out the battery very fast and it is not needed when shooting at high shutter speed.

Wedding photography was always my least favourite subject, you only have one chance so I know what your going through.

Where possible use a tripod, this will eliminate any camera shake (and you can be in the picture too by using the self timer). Turn anti shake off when using a tripod as it can sometimes add blur when the camera is fixed.

Use as wide an aperture as you can (try Aperture priority for this) then you are guaranteed that the shutter speed will be as fast as it can be. This will reduce Depth of Field particularly when use close up to your subject so keep an eye on where the camera is focusing.

Turn the ISO up to 400 or even 800 if the light is dim, interiors for example, this will increase noise, but at least you'll have a decent start image with less camera shake, better a slightly noisy image which can be sorted in post processing than an image with camera shake which can't.

Shoot in RAW, then you can adjust for most deficiencies in your shots, but it will make work for you, you can always use the RAW + Jpeg option then you have both, this helps with any high ISO pictures you have as you can reduce or even eliminate noise.

Things you can't alter in post processing are pictures that are out of focus, pictures where the (usually) sky is burnt out, pictures where the shadows have gone to black, this last one is where RAW can come to your rescue.

Photograph everything, with practise you can get a break as you learn when your needed and when you can just disappear for a while, but for someone without this experience just photograph everything, it's amazing how often that 'off the cuff' shot is the keeper.

For group shots carry a whistle, it's an old idea, but it does work, just before taking the shot give a blast on your whistle, the unexpected loud noise, everybody will be looking at the camera and everybody will have their eyes open, keep the camera rolling as this often leads to some hilarity which are good shots too.

Try to enjoy your day, I know it's difficult directing people when necessary whilst trying to concentrate on your photography, you never know it could be a new career for you.
