X- Speed

Also known as the shutter sync speed, is the maximum speed at which you can take a photo so that the frame is exposed correctly. You can shoot at speeds slower than the sync speed, but what happens if you shoot faster, I ll show you here.

The following photo is the auto exposed photo, no flash.

The one below is at 1/200 shutter speed. The max sync speed is 1/320.

The one below is at 1/320. Notice that there is a subtle difference in the light level, though not very noticeable.

The one below is at 1/400th of a second. Do you see a very thin line of black fringe beginning to show up in the photo?

Next, we go 1/500. The band is more visible now.

Here we go with 1/640. The band takes up about 1/3rd of the frame.

At 1/800th of a second, half of the frame is gone. The flash fires at the first curtain. So, by the time the flash is able to fire and light up the scene, the second curtain has already covered half the sensor.

At 1/1000th of a second, there is no effect of the flash and it as if the shot has been taken at 1/1000 speed without the flash on.

Now, if you are using only the onboard flash, chances are that the camera will not let you go past your sync speed as long as the flash is active. Same with the use of proprietary flashes from Nikon, Canon etc. But sync speed is an issue that must be tackled if using third party non sync flashes (the cheaper variety ones). To ensure that your photos don’t have the two-face kind of a situation, pay due heed to the flash sync speed of your camera.

Last time, X was for X Process.

I wish for all of you to have a wonderful time, be closer to achieving your dreams and making them real, and to having a superb year ahead! Happy New Year!
