iPhone XR delight for low-light photography: Experts

New Delhi, Nov 4: If you are looking to get that perfect low-light shot this Diwali, the newly-launched iPhone XR is capable of beating all other camera-centric smartphones, say experts.

According to Bengaluru-based photographer Ashish Parmar, the iPhone XR has a wide-angle lens – a 26mm f/1.8 lens – for portraits.

“The iPhone XR emulates the Portrait Mode effect entirely with software designed to recognise human faces. This means it’s really great at creating the Portrait Mode effect with people,” Parmar told IANS.

“You can also shoot quite close to your subject in Portrait Mode with iPhone XR (no “Move farther away” warning), he suggested.

On the single-lens iPhone XR, portraits are shot with its fixed 26mm lens, so the field-of-view is quite a bit wider and the image compression is reduced.

“The same new Smart HDR technology on this year’s iPhone XS is also available on the iPhone XR. This means better dynamic range in everything you shoot,” Parmar said.

Shooting in low-light can be tricky and needs steady hands.

“Look for brighter colours or spots which are receiving light and lock you AE/AF on that area. You will expose for a better lit part of the image and avoid making your image grainy,” suggested Parmar.

If you are shooting moving subjects like fireworks, shoot on LIVE mode as this allows to edit or convert images and make it a long exposure shot with smooth transitions.

“Performance will vary, but I think it’s safe to say the iPhone XR battery life is the best we’ve had in an iPhone yet,” said Parmar.

For Mumbai-based travel blogger and photographer Siddhartha Joshi, the iPhone XR camera sensor features deeper, larger pixels.

“Deeper to improve image fidelity and larger to allow more light to hit the sensor. The result? Even better low-light photos,” Joshi told IANS.

According to him, the camera is focused on portraits of people.

“I feel that it’s also really quick with finding faces and locking on them. This makes clicking portraits of people faster and a joy with the device,” said Joshi.
Portrait photography isn’t just about having a great subject.

“It’s also about having a great background. Also, make sure that your subject wears a colour different from the surrounding elements. Otherwise, your subject will blend into the background,” suggested Joshi.

Apple Watch future models to use micro-LED display: Report

Micro LED has the double advantage of offering less power consumption than the current Apple Watch screens, and of being thinner, too.

San Francisco, Aug 12 : Apple is reportedly planning to use a micro-LED display instead of an OLED panel in its future Apple Watch.

Apple could be using the MicroLED Display panel for the seventh-generation Apple Watch.

However, the upcoming Apple Watch, the sixth-generation model, will continue to have an OLED panel, reports DigiTimes.

Apple is investing around $330 million in the Taiwan-based company for a micro-LED factory that will manufacture displays for future iPhones, iPads, MacBooks, and other devices from Apple.

According to the report, Lee Biing-jye, chairman of Epistar which is the largest LED manufacturer in Taiwan, said that smartwatches will become the first major applications of Micro-LED. But the time for mass adoption may be 3-4 years.

A watch’s 300 x 300 pixels would require around 300,000 micro LEDs, he was quoted as saying.

Micro LED has the double advantage of offering less power consumption than the current Apple Watch screens, and of being thinner, too.

The main barrier to adoption is the micro-LED manufacturing process, which is complicated – glass substrates are used which need a lot of testing.

TikTok monitored device data in violation of Google policies: Report

While it is not clear why TikTok used the tactic to collect device data, it could be linked with its advertising goals.

San Francisco, Aug 12 : TikTok secretly collected device data for months via its Android app using a technique that Google prohibits developers from using without consent of users, The Wall Street Journal reported.

Although the practice came to an end in November, the finding could add to the woes of the short video-sharing platform which is facing threat of a ban in the US over its data protection practices.

TikTok’s Android app tracked MAC (media access control) addresses — unique hardware identifiers for networked devices — for at least 15 months over 2018-19, according to the WSJ report on Tuesday.

TikTok managed to hide the tactic through an “unusual added layer of encryption”, according to the report.

The short video-sharing platform owned by Chinese unicorn ByteDance reportedly took advantage of a security hole to collect the data.

It is not known if iOS users also fell prey to such tactics which were banned several years ago by both Google and Apple.

When the Journal reached for a reaction, TikTok said that MAC addresses are not collected by the current version of the app.

While it is not clear why TikTok used the tactic to collect device data, it could be linked with its advertising goals.

While Google did not comment on the loophole, it said that it was investigating the finding.

The news of TikTok collecting MAC addresses of Android users comes after iOS 14 revealed that the app was accessing iPhone clipboards more than necessary, Android Authority reported.

The finding comes in the same month the US President issued an executive order, prohibiting transactions by any entity in the country with its Chinese owner within 45 day.

TikTok was among the 59 apps that India banned in June.

Twitter testing automatic translation for tweets

If the primary language of the user is set to English within Twitter, all other Tweets in different languages will have a Translate button.

TWITTER

San Francisco, Aug 12 : Twitter has kicked off a test with a small group of users across iOS and Android in Brazil that automatically translates tweets that are in a language they may not be able to read.

“To make it easier to understand the conversations you follow on Twitter, we’re experiencing an automatic translation for Tweets in other languages that appear on your homepage,” the company said in a statement.

The translation is already a feature of Twitter, but it’s not automatic. The platform currently supports inline translations, so users can click on any tweet written in a different language to translate it.

If the primary language of the user is set to English within Twitter, all other Tweets in different languages will have a Translate button.

However, with the new feature, users in Brazil will see English-language tweets that have been automatically translated to Brazilian Portuguese, rather than having to manually opt to translate it themselves.

Twitter is also working on a new feature where the users will be able to view retweets with quotes (formerly known as retweets with comments) on each of their posts.

The ‘quote retweets’ will now appear as “Quotes” under tweets, with their own counter, similar to how the number of retweets and likes are displayed.
