Kit lenses that are sold with most consumer-grade DSLR cameras have small apertures (f4 to f8). Cameras with larger sensors can achieve longer focal lengths and subsequently better background blur. Sensor size: A small sensor has a short focal length and wide angle of view.To blur the background, use a long focal-length lens or a good variable-focus-length lens and zoom in on your subject. Zooming in on a subject narrows the angle of view and makes the focal length longer, resulting in more background blur. Focal length: A short focal length has a wide angle of view which keeps details in focus both in the foreground and the background.Distance from your subject: Moving closer to and focusing tightly on your subject and ensuring the background is far away from your subject make it easier to achieve a blurred background.The lower the f-value, the softer the background blur. When using a large aperture, the shutter speed should be faster to prevent the photo from being over-exposed. Larger apertures have smaller f-values and allow more light to reach the camera sensor. Aperture: Specified by an f-value or f-stops.Two of the three iOS 16 updates so far have focused on the iPhone 14 range, and this is unprecedented in my experience.The following aspects majorly affect the blurriness of background clutter: These are just a fraction of the issues buyers of iPhone 14 models have reported so far, but the focus on its newest phones again in iOS 16.0.3 does show Apple is aware of their buggy nature. Problems addressed included delayed call and app notifications, low microphone volume during CarPlay calls and sluggish camera performance. Second, Apple has released iOS 16.0.3, which predominantly features fixes for iPhone 14 models. This is an interesting insight, given the current problems with Crash Detection on rollercoasters, and leads me to believe that we’ll see significantly fewer false positives as Apple improves the algorithm. Interestingly, Drance revealed that Crash Detection had not activated for her during a minor fender bender because “we don't want to be doing a lot of false calls to 9-1-1 when they're not necessary." He said the company also worked with the Department of Transportation and NHTSA (National Highway Traffic Safety Administration) to understand which types of crashes are the leading causes of injury. Huang explained that Apple tested Crash Detection by placing iPhones “in many different places throughout the car - on the dummies and the car itself” while collecting raw data from cameras and pressure sensors. Your speed change, combined with the impact force, combined with the pressure change, combined with the sound level, it's all a pretty dynamic algorithm.” Depending how fast the traveling speed was earlier, determines what signals we have to see later on, as well. “It's hard to say how many of these things have to trigger, because it's not a straight equation. "There's no silver bullet, in terms of activating crash detection," admitted Ron Huang. First, Apple executives have spoken to TechCrunch about Crash Detection. As more and more iPhone 14 models are sold, this problem will only increase.ġ0/11 Update: two significant updates for iPhone 14 owners have occurred in the last 24 hours. Īpple also responded to the WSJ’s finding, telling the publication that “the technology provides peace of mind, and Apple will continue to improve it over time.” In the meantime, some rollercoaster owners are already warning users to turn on Airplane Mode on their phones and smartwatches before rides.Īpple’s pledge to improve Crash Detection is welcome and urgent. Despite this, subsequent tests have found the feature to have varying levels of accuracy - something Apple has defended. The report claims that at least six incidents have now been recorded of iPhone 14 models raising false alarms on the rides.Ĭrash Detection uses a combination of velocity, pressure, G-Force, GPS and volume measurements to limit errors, and Apple claims it tested the feature with over a million hours of car crash data and real-world driving analysis. The Wall Street Journal reports that some iPhone 14 models are triggering Crash Detection mode and automatically calling emergency services when used on roller coasters. #Pro lens blur update#iOS 16.1, a bigger update that also adds new features, should arrive by the end of the month.ġ0/10 Update: owners of Apple’s iPhone 14 range are reporting further problems, this time with Apple’s new ‘Crash Detection’ feature, which is exclusive to the new models. Brownlee also said he has been suffering from the CarPlay issues previously reported.Īpple is expected to release iOS 16.0.3 shortly, its third dedicated bug fix in less than a month. Replies to Brownlee’s tweet include plenty of other problems, such as Control Centre glitches and autofocus issues, but they appear more isolated.
