Don’t Miss Out on the Perfect Solar Eclipse Photo: Tips on Taking Pictures Today
Take these steps to minimize potential damage to your camera or phone lens, and get a great photo.
Today’s solar eclipse is the talk of the town. During its trip across North America, the total eclipse will hit parts of Mexico, a long diagonal stripe across the US and a stretch of eastern Canada. It’ll be quite the event, especially since the next total solar eclipse to hit North America won’t happen until August 2044.Â
Nearly half of the US population lives within a 200-mile drive of the event, giving many people a chance to catch a glimpse or a photo.
Remember, you must wear solar eclipse glasses if you’re looking up during the eclipse. While the sun will be completely hidden behind the moon for a few minutes, the rest of the eclipse will be just as harmful to human vision as it would be if you stared at the sun on any other day. So you’ll want to make sure that your solar glasses will protect your eyes while you watch.

You’ll want to protect your camera and its lenses, too, if you’re among the throngs who’ll be aiming a smartphone or DSLR at the sun in hopes of capturing that perfect image to share on social media of the last total solar eclipse in the US for the next 20 years.
Here are a few things to know before pointing your sensitive and expensive devices at the giant fireball in the sky.Â
Taking photos of the solar eclipse with a smartphone
A great many solar eclipse photos are likely to come from smartphones, given that just about everyone has one and that many are packed with very capable cameras.Â
First things first, you’ll want to pick up a solar filter. You don’t need anything fancy. You can buy little solar lenses that you can physically hold in front of your phone camera lens for a little over $10. In a pinch, you could use one of the lenses from a pair of paper solar eclipse glasses to achieve the same effect.Â
In general, your phone’s auto mode should take care of most of the heavy lifting. Phone makers have spent tons of time tuning the cameras to the appropriate settings to take the best possible picture. If you want to take matters into your own hands, you can always switch to manual mode — but do spend a bit of time before the eclipse familiarizing yourself with those settings.Â
A few other helpful tips:
- Turn off your flash. Once totality hits, you’ll be taking pictures essentially at night and your flash isn’t going to help. Plus, it can annoy people around you.
- Only use zoom if your phone is equipped with an optical zoom lens like the Galaxy S24 Ultra or the iPhone 15. Check your phone model to see if yours comes equipped with it. Using digital zoom will reduce resolution and make the image look blocky and unappealing.Â
- Most modern smartphones feature a burst shot mode. The crown jewel of eclipse photography, the diamond ring, is only visible for a split-second and a burst shot mode will give you better odds of capturing it than if you try to time it yourself.Â
- Practice. Taking good pictures of the sun is no easy task and you don’t want to spend the entire time fiddling with your smartphone camera settings.
- Google also recommends bringing a portable battery bank. Camera use is a huge battery drain, and you may need some extra juice.Â
Taking photos of the solar eclipse with a DSLR
Many of the rules for smartphone photography also apply if you plan on taking a DSLR or mirrorless camera to the event. The steps to get there are slightly different. Smartphones can use virtually any solar filter, but cameras require something that’ll fit on the end of your camera’s lens barrel since it’s very difficult to hold a filter while taking a picture with a regular camera.Â
You may think you need a UV filter for solar photography. In reality, you’ll want an ND (neutral density) filter. ND filters reduce the amount of light coming into the lens the same way solar eclipse glasses reduce the amount of light coming into your eyes. K&F Concepts has a good one designed specifically for celestial photography.Â
The next factor is size. Filters come in various sizes and the size you need depends on what lens you own. Check the barrel of your lens. You’ll want to find the ø symbol with a number next to it. That number is the millimeter size you need.Â
If your lens doesn’t have that measurement on it, you can find the measurements on the box the lens came in or on the manufacturer’s website. If you get an incorrectly sized filter, it won’t fit on your camera properly, so make sure you look before you leap since ND filters can get quite expensive.Â
Once you obtain a solar filter, the same general tips apply to a regular camera. Practice photographing the sun over the weekend before the eclipse so you can dial in your preferred settings. Use burst mode to capture the diamond ring, bring spare batteries, and make sure your equipment is in order before the event.Â
Camera owners may also want to consider bringing multiple lenses to get different types of pictures, and you should definitely bring a tripod if you’re planning on long exposure shots, or just for stability in general. (A remote shutter release helps as well.) If you’re comfortable with it, shooting in raw image format can also produce some amazing results after some editing.Â
Can I take photos of the solar eclipse without a filter?
Human eyes can be damaged in seconds when staring at the sun — and the same is true for eyes looking through an unprotected camera lens at the eclipse. Camera lenses themselves are a bit more resilient. They might be able to handle the occasional sun photograph, but the longer and more frequently the camera is pointed at the sun, the more likely it is that damage will occur.
This can happen in a variety of ways, including damage to the lens, camera internals and mounting hardware. Camera lenses are essentially fancy and expensive magnifying glasses, and anyone who used a standard magnifying glass to concentrate sunbeams as a kid already knows how dangerous it can be for things on the other side of the sunbeam.Â
You may be able to get away with the occasional snap of the sun with an unprotected camera without damage as long as it’s quick and it’s not a long-exposure shot (and you’re not looking directly at it yourself). However, given how expensive cameras, camera lenses and smartphones are, better to err on the side of caution and use a solar filter.Â
In addition to safety, the solar filter can also help you take more effective pictures of the sun. Cameras — especially smartphone cameras — often have a rough time with super bright lights like the sun. A solar filter will reduce the brightness so you’ll be able to get much cleaner pictures of the eclipse.Â
During the brief moment of totality, you might consider removing your solar filter. Everything will be so dark that it’ll be unnecessary, and it’ll help if you want a good shot of the corona. Just make sure to put it back on if you want photos as the eclipse wanes.Â
Don’t forget to actually watch the eclipse
This is the last total solar eclipse to run through North America until 2044. It’s a once-in-a-generation event, unless you plan on traveling to Russia in 2026 or Egypt in 2027. Remember to put the camera down at some point and enjoy the moment. A celestial event like this doesn’t happen every day.Â
While it is a singular event for us here on Earth, astronauts on the ISS will have three total opportunities to watch it.
If you live in the path of the solar eclipse, you’re also encouraged to leave pets indoors with lights on and shutters closed as the transition to nighttime in the middle of the day can cause stress to animals. And systems that run on solar power may experience significant impacts on solar generation, so that’s another thing to keep in mind.Â

OpenAI chief Sam Altman outlines why the AI sector is urging a slowdown: risk of losing control
Sam Altman and Dario Amodei call for a measured pace in AI development, proposing safety frameworks and international coordination to avoid losing control, while U.S. and Chinese tensions underscore the urgency.
OpenAI’s Sam Altman offered the most thorough remarks to date on potential AI safety frameworks, following his alignment with Anthropic’s Dario Amodei and Elon Musk in urging a temporary slowdown of the sector. Tensions surrounding AI safety have surged after an Anthropic researcher resigned last week, claiming that developers feared the technology could “cause humanity’s demise by the end of the decade,” a warning that spurred similar alarm among OpenAI staff and other lab members. The leaders of major AI firms have recently shown uncommon agreement, as Altman and Musk jointly endorsed Amodei’s essay calling for a measured pace in advancing the most powerful AI models. AI‑related stock prices fell on Monday as investors reacted to the statements, while U.S. President Donald Trump rejected the CEOs’ caution on Sunday, arguing that a slowdown would hinder America’s dominance in AI compared with China. Sam Altman outlines two potential disastrous outcomes for AI development. Altman stated in a late‑night X post that a federal framework establishing uniform safety standards for frontier AI is welcome, emphasizing that “no level of American competitive pressure can excuse reckless behavior.” He warned that AI advancement might lead to loss of control over future outcomes and could concentrate excessive power in the hands of a single individual or corporation. At the same time, Washington legislators are rushing to respond to demands for regulatory safeguards. The developments occur as Anthropic and OpenAI prepare for what could be historic initial public offerings, with Altman stating in a Fortune interview on Saturday that the companies will not pursue an IPO in 2026. Amodei’s three‑step plan. A primary safety concern involves models gaining the capacity to enhance their own performance, a process called recursive self‑improvement (RSI). He noted that since early summer AI has been progressing rapidly, largely because AI systems are now capable of creating the next generation of AI themselves. He warned that without oversight, the technology could outpace our capacity to comprehend and control it, making careful, possibly restrained, development essential. He outlined a three‑step approach designed to slow development while preserving commercial benefits and maintaining the United States’ competitive edge in AI. The plan calls for every frontier AI company to provide external evaluators with access comparable to that of employees — a commitment Anthropic has already made — and urges all such labs to adopt shared safety standards, curb uncontrolled AI acceleration, and coordinate globally. On Saturday, Altman posted on X that he concurred with Amodei’s call for AI firms to “pace the frontier,” adding that adopting independent evaluators with employee‑level access is a worthwhile step and that his company will follow suit. Altman said in a Monday post that consistent regulations to manage frontier risk — such as independent auditors — are valuable, but clarified that “pacing” does not equate to halting progress, which remains swift and ongoing. He concluded that the costs of pacing are justified, asserting that no level of American competitive pressure can excuse reckless actions that let capabilities outpace alignment and monitoring. He noted that governmental assistance will be needed for international coordination, but emphasized that the industry should first act independently. Coordinating AI safety measures and a sector‑wide slowdown with Chinese AI developers will present significant hurdles. The United States and China continue a rivalry for AI supremacy, with tensions rising as Chinese models become increasingly sophisticated and widely adopted. He added that the toughest aspect of his proposal is the possibility that rival nations may decline to adopt similar measures. He noted that the long‑term goal would be collaborative effort to impose a speed limit on AI progress, according to an interview with CBS News’ “Sunday Morning.” He acknowledged that achieving such a limit would be challenging due to strong incentives to get ahead and the military advantages involved, admitting uncertainty about feasibility but urging an attempt. The essay has attracted criticism in China, with state‑owned Global Times stating on Monday that “Amodei’s proposals aim to cast China’s legitimate AI development as a threat and exacerbate U.S.–China confrontation.” China’s Foreign Ministry responded on Monday, labeling the CEOs’ remarks as “fearmongering.”

Novo CEO tells CNBC why drugmaker is rebranding, needs to ‘rethink’ obesity strategy
The Danish drugmaker called the changes the beginning of a new chapter for the company, which faces stiff competition from Eli Lilly.
Novo Nordisk
The Danish drugmaker called the changes the beginning of a new chapter, as it has been grappling with stiff competition from chief rival Eli Lilly
In an exclusive interview with CNBC, Novo CEO Mike Doustdar said the rebrand and culture shift are “part of the same package” for the company to evolve its strategy as it tries to win back customers from Lilly.
“I think there’s no secret that over the last four or five years, the external environment and what has happened to Novo Nordisk has really made us reflect how we need to readjust and rethink about the next decade to come and what shifts are needed in our strategic direction,” he told CNBC.
Doustdar said the “work is cut out for us,” adding that Novo needs to improve several aspects – from research and development and manufacturing to sales and marketing – to be able to compete in the obesity drug market.
Shares of Novo have dropped about 15% this year despite the successful launch of the oral version of Wegovy, which surpassed 3 million prescriptions as of June. The company recently scrapped three trials on an experimental cardiovascular drug. That challenge came as it continues to lag in the obesity space with 38.8% market share compared to Lilly’s 60.9% in the second quarter, according to a Lilly earnings presentation citing IQVIA data.
In a release, Novo also announced a broader company rebrand focused around the phrase “Lasting Health Starts Now,” which promotes the idea that patients should make progress toward long-term well-being immediately rather than later. The company said the marketing is a bid to build relevance and trust with the public and other stakeholders, and bring “breakthrough science closer to people’s daily lives.”
When asked whether the rebrand and cultural overhaul were driven by Novo’s recent market share losses in obesity, Doustdar said the changes were less about competitive setbacks and more about adapting to a dramatically different operating environment.
He said the rapid growth of obesity treatments has transformed Novo’s patient base and shifted the market toward a more consumer-oriented model, where patients move on and off therapies more frequently than in traditional diabetes care. As a result, Doustdar said Novo needs to become more focused on meeting patients where they are, while increasing the speed and clarity of its decision-making to keep pace with the evolving market.
“Our operating environment phenomenally changed compared to just 10 years ago,” he told CNBC.
Novo Nordisk will remain the legal name for the company, according to the release. That original name dates back to the 1989 merger of two competing Danish pharmaceutical companies: Novo Terapeutisk Laboratorium and Nordisk Insulinlaboratorium.
The drugmaker said its corporate culture will be based on a new set of four principles that will help it gain advantages in an increasingly competitive market where more of its products have gone direct-to-consumer.
Those tenets are innovating with patients as the primary focus, raising the company’s performance to “create greater value for all stakeholders,” setting clearer priorities and simpler workflows and never compromising on patient safety and ethics.
“When you think about strategy, that’s really the the journey you’re taking and the direction you’re setting the company to go forward with,” Doustdar said. “But you also need behaviors. You need a cultural element that allows your colleagues and yourself to really make sure that a strategy gets executed.”
Despite its challenges, Novo has had one significant tailwind this year in the launch of the oral version of Wegovy. On top of its explosive launch, the pill had a head start over a rival weight loss pill from Lilly called Foundayo.
Doustdar said Novo has maintained “a lion’s share” of the oral market even with competition, noting that physicians find the Wegovy pill to be more effective than Lilly’s, with around 17% of weight loss.

Iran Claims It Shot Down U.S. Advanced Drone Near Hormuz as Middle East Tensions Rise
Iran says it shot down an advanced U.S. drone over the Strait of Hormuz amid rising tensions and stalled diplomacy. President Trump linked the conflict to potential oil control, citing the Venezuela deal and predicting lower gas prices if the war ends.
Iran’s military announced it had shot down a sophisticated American drone above the Strait of Hormuz, marking the latest volley in a cycle of warnings and strikes between Tehran and Washington that shows no sign of easing.
The Islamic Revolutionary Guard Corps stated on Monday that its newly unveiled advanced aerospace defense system intercepted and destroyed an advanced MQ‑1 drone over the Hormuz strait, offering no further details about the drone’s mission. The MQ‑1, built by U.S. defense contractor General Atomics, has historically been flown mainly by the U.S. Air Force and the CIA.
The downing comes after a string of Iranian actions targeting U.S. unmanned naval assets in the Gulf, as the conflict, now in its seventh month, continues with little de‑escalation and diplomatic efforts over the vital waterway remain stalled.
On Sunday, President Donald Trump said the United States could keep pressing its campaign against Iran and seize control of its oil, comparing the situation to the agreement Washington reached with Venezuela earlier this year.
“We’ll ultimately get out (of the war), unless we decide to stay and keep the oil like Venezuela,” Trump remarked at the Irish Open golf championship in Ireland. He added that the revenue the U.S. gains from the Venezuela deal — which gave Washington access to about one‑fifth of Venezuela’s oil reserves — has “paid for the war many times.”
Under the August agreement, Venezuela handed over majority U.S. control of more than 65 billion barrels of oil reserves — more than twice the size of America’s own reserves — in exchange for $209 billion deposited into Venezuela’s state treasury. Secretary of State Marco Rubio said the pact would also attract roughly $100 billion in private investment to help revive the Venezuelan economy.
Trump also said on Sunday that he expects the seven‑month Iran war to conclude this year, perhaps after the November midterm elections, and insisted that gasoline prices would “drop like a rock” once the conflict ends.
He stressed that he would only accept the “right deal,” noting that Tehran has been “calling constantly” for peace talks, a claim Iran has previously rejected.
**Stalled Hormuz talks**
A planned meeting in Oman between Gulf states and Iran to discuss possible arrangements for the Strait of Hormuz — the crucial conduit for global oil and gas shipments — was postponed, Omani Foreign Minister Badr Albusaidi said on X on Sunday, citing the need for “consensus.”
Iranian and Gulf officials had been slated to meet on Monday to sign an accord establishing an Iran‑Oman shipping lane through the Strait of Hormuz, although no direct negotiations between the United States and Iran were underway at that time.
Since the war began in February, the Strait of Hormuz has been under an Iranian‑led naval blockade, later joined by U.S. forces, keeping global energy prices elevated.
A June agreement between Washington and Tehran collapsed over disagreements about the waterway, and a recent surge in attacks by Yemen’s Houthi rebels — an ally of Tehran — has given that group leverage over another key chokepoint, the Bab el‑Mandeb.
Vessels deemed non‑compliant are routinely struck by Iranian forces, while the United States periodically launches strikes on the Iranian coast to challenge the Islamic Republic’s hold on the strait.
Oil prices climbed above $100 a barrel again for the first time since May and rose further on Monday after Saudi Arabia shut a major East‑West energy pipeline following damage from Iraqi drones.
U.S. West Texas Intermediate futures gained 2.3% to $102.39 per barrel, and Brent crude, the global benchmark, rose 2.4% to $107.11 per barrel.
