When shooting subject with low light situation, you got only two options; either to shoot with a flash or to shoot with a slow shutter speed.
With the flash, your subject will be lit well and if the subject is moving then it will be frozen and as a result will be sharp. problem with this is, no time to capture ambient light and cannot capture motion blur.
With the slow shutter speed, you will have enough time capture the ambient light and still subject, what if the subject is moving? you will capture the motion blue, and also the blurry subject.
You can achieve motion blur with sharp subject using "Slow sync flash".
Focal Length : 29 mm, Shutter Speed : 0.6 sec, f stop(Aperture) : f/5.6, ISO : 400, White Balance : Auto
Have you heard of Rear and Front curtain sync or flash?
Rear Curtain sync instructs your camera to fire flash just before closing the shutter. Front Curtain sync instructs your camera to fire when exposure begins or right after shutter opens.
Mount your camera onto the tripod, then lock the focus.. once everything set, put your flash to manual mode and make the power of flash to 1/3. Now put flash to rear sync. Once you click the shutter release button, move your subject, at the end of the exposure camera fires a flash to freeze the subject. Look at the result.
Off camera flash yields better result than the on camera flash, because you can fire the strobe wherever you want. Take a look at the below image, i fired the flash light on top of the subject by using cellphone.
Focal Length : 50 mm, Shutter Speed : 1/160 of a sec, f stop(Aperture) : f/2.8, ISO : 200, White Balance : Auto
Gears you need:
Camera with wide aperture if you are shooting in low light, i used Nikon 50 mm AF 1.8 G lens on my Nikon D3100
Cellphone with flash and an app to fire flash. Free app for Android and iOS
Use your three legged friend tripod to hold camera and you can fire strobe on subject.
Follow these steps:
Put your camera into manual mode.
Focus the subject and move the lens's focusing switch to Manual mode to lock the focus.
Fire the strobe on top the subject, and click your shot. I shot this image at night.
