Summary

The video, hosted by Shayne Mostyn, delves into the evolution of astrophotography using iPhones, culminating in a hands-on test of the (hypothetical) iPhone 18 Pro Max. Mostyn begins by humorously referencing his journey from testing the iPhone 11 Pro’s initial Night Mode—a “pretty exciting” introduction—through the subsequent 12, 13, 14 (which significantly improved after an iOS update), and 15 Pro Max models. Each iteration brought noticeable enhancements, with the iPhone 15 Pro Max previously lauded for its “mint” astrophotography capabilities. The iPhone 18 Pro Max is presented as a pivotal moment, as Apple has now officially embraced and promoted astrophotography as a key feature.

Central to the iPhone 18 Pro Max’s advancements are its rumored larger sensor, promising better low-light performance, and a new variable aperture. Historically, iPhones operated with a wide-open aperture (around f/1.8), but the 18 Pro Max allows users to select between f/1.48, f/1.8, f/2.8, and f/4. Mostyn explains that the iPhone’s computational photography excels by taking multiple 10-second exposures within a 30-second capture, intelligently focusing and exposing across these shots to ensure sharpness in both foreground and distant stars. Due to unexpected cloudy weather affecting his planned rock outcrop composition, Mostyn adapted by testing the different aperture settings on a tripod with a subtly lit foreground tree, aiming to evaluate the new model’s low-light and focusing capabilities.

The comparative results from the different aperture settings revealed distinct visual characteristics. The f/1.48 setting captured the most stars and detail but exhibited some “artifacting” or digital noise in the sky. Mostyn identified f/1.8 as the “sweet spot,” providing a more natural appearance with good detail and less noticeable digital artifacts. As the aperture closed further to f/2.8 and f/4, the images progressively darkened and lost significant detail, reminiscent of older iPhone models like the 11 Pro. Post-processing in Adobe Lightroom (a process also achievable on mobile) involved masking the sky and applying minor dehaze and clarity adjustments to enhance the raw images.

In conclusion, Mostyn declares the iPhone 18 Pro Max a substantial leap forward for mobile astrophotography, surpassing the iPhone 15’s performance. He highlights that while professional cameras offer ultimate flexibility, the iPhone’s computational photography makes night sky photography remarkably accessible and effective, even negating the need for external shutter releases due to its internal processing. The video reinforces that the iPhone 18 Pro Max is not just a casual tool but a capable device for capturing impressive astrophotos, allowing users to delve into this rewarding genre of photography without needing specialized, expensive gear.
