TV | shutter speed

March 10, 2018

Let’s move on in the camera training with the mode TV (Time Value). On some cameras this mode is also called S. This mode is needed when you are going to shoot objects which are moving fast or just aren’t staying still. Let’s say a football match or if you are on a concert. The Shutter Speed defines how long the lens will be able to collect light. If you are shooting outsite at daylight you can set your Shutter Speed short as there is enough light to take the photo.

Let me explain the values a bit. If your TV value is set to 1/1000 it means that the lens will be able to collect light for a millisecond (0.0001 second). Which is a pretty short time. It’s okay if you’re outside but let’s say there’s a birthday party of your friend in the evening. Then 1/1000 won’t be anough time for the lens to collect enough light the make the photo acceptable. You will only get a plain black photo. Set your Shutter Speed to 1/125 (0.008 seconds), give your lens more time to get enough light and you will have a beautiful photo with all your friends smiling on it. The problem here is that the more you give time to the lens to collect light, the lesser the object may move in front of the camera.

.Here’s an example different Shutter Speed and it’s effect on moving objects:

Now a high Shutter Speed time combined with moving objects isn’t always bad. There are effects you have pretty sure seen already. For example the photos you see of a dark street with light tails. You can do this by setting the Shutter Speed to, let’s say 15 seconds and you capture a street where cars drive by. The camera will only capture the light of the cars and you will get that beautiful effect. Same goes for waterfalls. Ever seen a picture where a waterfall looks like wadding? That’s how you do it. Long Shutter Speed and a tripod to make the rest of the image, which isn’t moving, look sharp.
