Posted by HOST on 1/27/2006, 11:36 pm, in reply to "Subject Motion" First, is "shutter lag", the amount of time it take the camera to actually take the photo once you press down on the shutter button. Second is shutter speed - how long the shutter stays open once you press the shutter button. If it takes too long for the camera to take the pic once you press the shutter button, the subject movement can blur, or, you may move the camera slightly during the lag time it takes to take the photo. Many people use their cameras in full "auto" mode, and the camera may not pick a fast enough shutter speed to freeze motion on moving objects. If the shutter speed is too slow and the shutter stays open too long, anything moving will appear blurred. This comes in handy when you want to do something like make moving water appear foamy, but not for kids or pets. Most consumer cameras have these issues to one extent or another. If you want the upmost in speed, the real way to go is a digital SLR (DSLR). DSLRs are much much quicker than consumer cameras in regards to any shutter lag times (almost nonexistant), and they offer full range of shutter speed controls as well. The cheapest right now you can get by with is something like the Nikon D50 which if you shop around you can find for about $650.00. If this is out of your range, you can at least minimize these problems by using a consumer camera that has manual controls for the shutter speed, and use faster shutter speeds for moving subjects. 1/500th to 1/1000th of a second is usually fine for catching stuff like pets and kids - faster if it's a fast action sport, etc. HOST Link: Digital Camera Basics.com
There are two things that will have an effect on subjects like kids and pets.
