What would be the best ISO, shutter speed and whatewer else I need to know if I want to take a nice, crisp picture of kids outdoors+the background blury. I have a 18-105mm lense. Will that work? Thank you!
If you want the background to be out of focus, you will have to shoot with your lens wide open and your kids close to the camera with it at 105 mm setting.
Just use your light meter to get the correct exposure in any case.
