Zoom burst photography is an abstract photography technique that is achieved by zooming your lens in or out whilst the exposure is being taken.
To get the desired effect, you'll need your Tamron zoom lens and a tripod, to keep the image steady. This will also allow you to have your hands free to smoothly control the zoom. You'll also need a remote cable release to eliminate any shake caused by pressing the shutter. If you don't have one, then use the self timer setting on your camera. Using the flash on your camera or an external flash gun can help to add sharpness and freeze the image too.
The key to success with this technique is to get the amount of zoom burst right. If the zoom is too obvious then it may disguise the subject. If you don't zoom enough, then the image won't have the desired effect. You don't want your exposire to be too long, otherwise your shots will be overexpoesd, but it needs to be long enough to enable you to create the zoom effect.
To create the effect you can zoom in or out, most people choose to zoom out. Press the shutter and wait for a while, around half to three quarters of the exposure should do it, and then you need to zoom out in a smooth and fast manner. Leaving the image to develop for half to three quarters of the exposure beforehand allows some definition to be captured in the image before the zoom is added.
Use a small aperture, and an ISO of 100 or 200 for the best results. If you find that your images come out overexposed, it's probably best not to make the exposure time shorter as this will make it more difficult to fit the zoom in. Fit a polarising filter or ND filter instead and try again.
It's then quick and easy to see on the screen if your attempt worked, if it didn't you can try again straight away. Experiment with the shutter speed and zoom timing until you find something that works for you and your subject.
