The most effective way to combat the problem is to shoot with a manual lens. This may be an old lens made by the manufacturer of your camera or a modern third-party option from the likes of Samyang or Tokina But when shooting a sequence of images for time-lapse, that difference becomes noticeable as flicker because of the ever so slight variation in exposure. The problem here is that each time the aperture stops down to take a shot, the exact amount it closes down to is imperceptibly different each time, which makes no difference when shooting generally. We’ve already discussed flicker, and one of the other causes of flicker is autofocus lenses. And if your camera has a built-in intervalometer you won’t even need a shutter remote with one built in. The great thing about time-lapse photography is that it can be as simple or complicated as you like, so at the basic end there’s very little you actually need beyond a camera, kit lens and tripod. More advanced software can remove this, but there’s also another way of reducing this problem and it all comes down to the lens you use. One of the problems with aperture priority is that if there are flashing lights or quick changes in brightness between one shot to the next, the camera will be fooled into under and overexposure which will ultimately result in flicker.įlicker is when the brightness of frames is slightly different so that when the time-lapse is played back as a video you see a flicker. When shooting in this mode you’ll need to set the necessary amount of exposure compensation if required. This is the mode where you set ISO and aperture, and the camera sets the appropriate shutter speed for a correct exposure. The second, and easier, option is to shoot in aperture priority mode. An advanced version of this is where you shoot a day to night scene and make minor adjustments to shutter speed and ISO as the scene gradually darkens. The first is to put the camera into manual mode so that exposure is fixed and any brightening or darkening of the scene will be picked up. You can reduce the likelihood of these inconsistencies by choosing as low an f-number as possible for your sequence.There are two main options for shooting mode when shooting a time-lapse. This is caused by minute inconsistencies in the aperture size in each exposure, and can occur even when you are using the exact same f-number in each shot. Another potential hazard is known as aperture flicker. The longer your exposure, the more risk you run of flicker – that is, fluctuations of light between exposures – spoiling your shots. ![]() If you’re shooting the progress of crawling kudzu, give it one or two minutes of exposure. As a rule, try to match your exposure time to the subject: slow moving natural phenomena require a slightly longer exposure, while rapidly moving subjects can be captured with one or two seconds. Keep the interval of time between shots consistent, or your sequence will appear jumpy and choppy. Your f-number, shutter speed and white balance should all be manually set by you, the artist. Once recorded, this process can be repeated automatically a huge time-saver.īe sure to select manual settings on your camera in order to avoid inconsistencies between exposures, or flicker. Use Actions to record all the commands used during photo editing. Both Windows and Mac users also have several software options, depending on the type of camera. Some cameras have built-in intervalometers, but if yours doesn’t, external ones are available for less than $150. Extra-long exposures can provide interesting effects in a time-lapse sequence, like streaks of light created by passing cars. An intervalometer can also allow you to take long exposures, up to several hours. In addition to being tedious, taking each frame manually is almost impossible to do at perfectly consistent intervals without mechanical or electronic help, and as a result, your sequence will be jumpy and choppy. If you are shooting without one, you will have to manually trigger each exposure at specific points in time. An intervalometer, or interval timer, as the name suggests, is a device programmed to set off the camera shutter at specific intervals of time. A DSLR with an intervalometer will save you a lot of headache. Having chosen a camera, the next thing that needs to be taken into account is shooting at set intervals. ![]()
