The Verge - The real story of the iPhone 18 Pro's camera | The Vergecast

发布时间:   原节目
《The VergeCast》播客由杰克·卡斯特罗纳基斯主持,大卫·阿梅尔担任客座主持。节目开始时,他们介绍了播客新一季《Version History》的最新进展,本季主题为“返校季”。节目将涵盖俄勒冈小道、高射投影仪和“每个孩子一台笔记本电脑”倡议等话题,预告片中还幽默地将TI-84+计算器描绘成一台“游戏机”。 主要讨论很快转向了苹果的iPhone 18 Pro。杰克和大卫与艾莉森·约翰逊一起,对智能手机摄像头“大谈特谈”。在深入技术细节之前,他们提到了苹果首席执行官约翰·特纳斯最近在艾美奖颁奖典礼上的公开亮相,并将他“摇滚明星般的风范”以及与人们的互动(甚至用iPhone 18 Pro自拍)与蒂姆·库克更为内敛的公众形象进行了对比。 iPhone 18 Pro 的摄像头得到了详细的解析。尽管苹果将可变光圈作为一项重大升级来强调,但艾莉森和大卫认为底层软件改进更为重要。这些改进包括原生相机应用中增强的“专业控制”,允许手动调整,例如长达一秒的长曝光和白平衡,以及重新设计的图像处理流程。大卫解释了信噪比的概念,以及更大的光圈(如iPhone 18 Pro)意味着更多的光线数据,从而减少了对过度锐化等激进计算摄影的需求。这使得画面色彩“不那么塑料感”,看起来更自然,即使在 HEIF 模式下也是如此。艾莉森也注意到她的 JPEG 照片中出现了这些积极变化。他们讨论了可变光圈的实用性,认为对于微型传感器来说,它通常可以忽略不计,但承认其对未来更大传感器的潜力。扩展的摄影风格也得到了讨论,其中提供了纹理和颗粒选项,大卫表示希望能够进行更精细的颗粒控制。 节目探讨了一项旨在打击人工智能伪造的新“参考图像技术”。该功能允许用户在像素级别对图像进行加密签名,从而创建出照片从传感器输出时的“数字底片”版本。该过程目前很复杂,需要特定的相机模式并与私有云计算进行交互,并且文件大小会翻倍。虽然对于需要证明真实性的摄影记者很有用,但它不适合日常使用,被视为早期的“概念验证”。大卫和艾莉森都强调了该功能的自愿性质及其仅限于 iPhone 生态系统的局限性,并将其与 C2PA 或谷歌 SynthID 等行业标准进行了对比。展望未来,艾莉森希望主摄像头能配备 1 英寸传感器和有趣的附加长焦镜头,而大卫则希望改进低光和天文摄影功能,并提到了苹果目前在更大光圈方面的努力。大卫还推测了 iPhone 的接力功能,认为它支持拥有多部 iPhone 的想法,例如用 iPhone 18 Pro 拍照,用 iPhone Duo 进行日常使用。 对话随后转向了“AI 安全危机”。The Verge 的高级 AI 记者海登·菲尔德讨论了最近因 Anthropic 研究员雅各布·考克森发布推文,警告 AI 有可能在十年内杀死所有人而引发的公众恐慌。海登解释说,由于最近涉及 OpenAI 和 Hugging Face 的网络攻击,引发了人们对 AI 系统“失控”的担忧,这条信息引起了共鸣。大卫质疑 AI 实验室的责任,将其比作狗咬人后狗主人的责任。海登表示同意,指出公司经常使用被动语态来推卸责任。讨论还涉及安全警告是否仅仅是营销炒作;海登表示,尽管强大的 AI 具有营销优势,但失控的系统对企业客户不利,这表明存在真正的担忧。 Anthropic 首席执行官达里奥·阿莫代伊回应了一篇博文,提议“放缓 AI 发展的前沿速度”,建议设立嵌入式评估员、达成国家和国际协议。OpenAI 的山姆·阿尔特曼迅速表示支持。海登的报告强调了此前第三方审计的局限性,例如 OpenAI 对 Hugging Face 事件进行的为期六天、仅限七个问题的审查。她指出,虽然嵌入式评估员获得访问权限是向前迈出的一步,但公司仍控制着范围,且该过程在很大程度上是自愿的,形成了“囚徒困境”,每个实验室都有动机秘密超越其他实验室。中国的影响和缺乏健全的外部监管也被讨论为复杂因素,这使得“负面新闻”成为目前为数不多的问责机制之一。 快速问答环节开始时,提到了一个关于 Waymo 的奇特事件:两名青少年在乘坐 Waymo 时携带一支幽灵枪被捕,这违反了 Waymo 的服务条款,也可能违反了枪支法律。Waymo 联系了执法部门。这引发了一场讨论,涉及自动驾驶汽车中未知的监控程度、这些系统如何检测和报告违规行为的透明度不足,以及随着自动驾驶交通日益普及所需的社会转变。Waymo 的声明表示,他们使用自动化技术检测枪支等违规行为,并可能联系执法部门。 接下来,大卫讨论了“电子阅读器革命”,重点介绍了新款 Boox Palma 3。这款智能手机形状的电子阅读器,以其时尚的铝制机身和运行 Android 16 而脱颖而出,这与之前型号的老旧 Android 版本相比是一项重大升级。该设备售价 339 美元,配备 128GB 存储空间和大容量电池,旨在提供优质的电子阅读体验,并支持手写笔。大卫指出,电子阅读器市场竞争日益激烈,像 XTE Inc 这样的公司也发布了紧凑型设备。 最后,艾莉森展示了两款“小巧可爱的相机”:Camp Snap 110D 和富士 Instax Pal 2。Camp Snap 110D 是一款数码相机,造型模仿复古 110 胶片相机,以其独特的低保真美学而闻名,并提供“梦想甜筒”和半透明版本等有趣的颜色。Instax Pal 2 是一款宽而窄的拍立得相机,配备 LCD 顶部取景器和 USB-C 端口,可直接传输到手机,这是对出了名差劲的相机应用的回应。这两款相机都迎合了“不好但迷人”的数字摄影趋势,以低于复古数码相机的成本提供复古外观。

The VergeCast, hosted by Jake Kastronakis with guest host David Amell, opened with updates on the podcast's new season of "Version History," themed "Back to School." Episodes will cover topics like the Oregon Trail, overhead projectors, and the One Laptop Per Child initiative, with a trailer highlighting a humorous take on the TI-84+ calculator as a "game console." The main discussion quickly turned to Apple's iPhone 18 Pro. Jake and David were joined by Allison Johnson to "geek out" about smartphone cameras. Before diving into the technicals, they noted Apple CEO John Ternus's recent public appearance at the Emmys, contrasting his "rock star vibe" and engagement with people (even taking selfies with the iPhone 18 Pro) with the more reserved public persona of Tim Cook. The iPhone 18 Pro's camera received a detailed breakdown. While Apple highlighted the variable aperture as a major upgrade, Allison and David suggested that underlying software improvements were more significant. These included enhanced "pro controls" in the native camera app, allowing for manual adjustments like long exposure up to a second and white balance, and a re-engineered image pipeline. David explained the concept of signal-to-noise ratio and how a larger aperture (like the iPhone 18 Pro's) means more light data, reducing the need for aggressive computational photography like excessive sharpening. This results in "less plasticky" and more natural-looking colors, even in HEIF mode. Allison also noted these positive changes in her JPEG photos. They debated the utility of the variable aperture, concluding it's often negligible for tiny sensors but acknowledged its potential for future, larger sensors. The expanded photographic styles, offering options for texture and grain, were also discussed, with David noting a desire for finer grain control. A new "reference image technology" designed to combat AI fakes was explored. This feature allows users to cryptographically sign images at the pixel level, creating a "digital negative" version of a photo as it came off the sensor. The process is currently complex, requiring specific camera modes and interaction with a private cloud compute, and doubles the file size. While useful for photojournalists needing to prove authenticity, it's not practical for everyday use and is seen as an early "proof of concept." David and Allison both highlighted the voluntary nature of the feature and its limitation to the iPhone ecosystem, contrasting it with industry-wide standards like C2PA or Google's SynthID. Looking ahead, Allison wished for a 1-inch main camera sensor and fun attachment telephoto lenses, while David hoped for improved low-light and astrophotography capabilities, noting Apple's current efforts with wider apertures. David also speculated on the iPhone handoff feature, suggesting it supports the idea of owning multiple iPhones, like an iPhone 18 Pro for cameras and an iPhone Duo for general use. The conversation then shifted to the "AI safety meltdown." Hayden Field, The Verge's senior AI reporter, discussed the recent public freak-out spurred by Anthropic researcher Jacob Coxon's tweet warning of AI's potential to kill everyone within a decade. Hayden explained that this message resonated due to recent cyberattacks involving OpenAI and Hugging Face, which raised concerns about AI systems "going rogue." David questioned the responsibility of AI labs, drawing an analogy to a dog owner whose dog bites someone. Hayden agreed, noting that companies often use passive language to deflect responsibility. The discussion also touched on whether the safety warnings were mere marketing hype; Hayden suggested that while there's a marketing benefit to powerful AI, uncontrolled systems are bad for enterprise clients, indicating genuine concern. Dario Amodei, Anthropic's CEO, responded with a blog post proposing to "pace the frontier" of AI development, suggesting embedded evaluators, national, and international agreements. Sam Altman of OpenAI quickly echoed support. Hayden's report highlighted the limitations of previous third-party audits, such as OpenAI's six-day, seven-question-limited review of the Hugging Face incident. She noted that while embedded evaluators gaining access is a step forward, the companies still control the scope, and the process remains largely voluntary, creating a "prisoner's dilemma" where each lab is incentivized to secretly outpace others. The specter of China and the lack of robust external regulation were also discussed as complicating factors, making "bad press" one of the few current mechanisms of accountability. The lightning round began with a curious incident involving Waymo: two teenagers were arrested after riding in a Waymo with a ghost gun, violating both Waymo's terms of service and potentially gun laws. The Waymo contacted law enforcement. This sparked a discussion on the unknown extent of monitoring in autonomous vehicles, the lack of transparency about how these systems detect and report violations, and the societal shift needed as autonomous transport becomes more common. Waymo's statement indicated they use automated technology to detect violations like firearms and may contact law enforcement. Next, David discussed the "e-reader revolution," highlighting the new Boox Palma 3. This device, a smartphone-shaped e-reader, stands out for its sleek aluminum body and runs Android 16, a significant upgrade from previous models' older Android versions. Priced at $339 with 128GB of storage and a large battery, it aims for a premium e-reading experience, also supporting a stylus. David noted the burgeoning competition in the e-reader market, with companies like XTE Inc also releasing compact devices. Finally, Allison presented two "tiny, adorable cameras": the Camp Snap 110D and the Fujifilm Instax Pal 2. The Camp Snap 110D is a digital camera styled after vintage 110 film cameras, known for their unique, lo-fi aesthetic, and comes in fun colors like "Dreamsicle" and translucent editions. The Instax Pal 2 is a wide, narrow instant camera with an LCD top-level viewfinder and a USB-C port for direct transfer to phones, a response to notoriously poor camera apps. Both cameras tap into a trend for "bad but charming" digital photography, offering a retro look at a lower cost than vintage digicams.
