Testing the new iPhone 15 Pro with Harvest Moon

Cameras of the iPhone 11 Pro, iPhone 13 Pro, and iPhone 15 Pro

I went to San Francisco to pick up my iPhone 15 Pro on the launch day, September 22, 2023. The primary advantages of this model over the previous ones are USB-C support and reduced weight. Unless you were getting a Pro Max version, the camera on the Pro series did not get much of a hardware improvement. So when I decided to do some comparison shots with the Harvest Moon photography during the Chuseok holidays, I chose some older models - iPhone 11 Pro and iPhone 13 Pro.

There were expectedly some notable quality differences between the three models. While iPhone 11 Pro does have a three-lens setup like the rest, the telephoto lens is only capable of 2x zoom. As a result, the size of the Moon in the photo was the smallest and least detailed. Both iPhone 13 Pro and 15 Pro have the 3x zoom lens on them, but for some reason the 15 Pro shot a consistently sharper image. Perhaps a slight hardware and software processing differences were at play. In the end, the latest was indeed the best.

Further details of the shooting sessions have been outlined in a separate video.

Witnessing Nuri (KSLV-II) rocket's successful 3rd launch

Launch of the Nuri rocket on 6:24 PM, May 25, 2023 (KST)
After returning mostly empty-handed the day before due to the scrubbed launch, I set out to Nangdo again on May 25, 2023, to watch the second attempt of the third launch of the Nuri rocket, a.k.a. KSLV-II. The weather was much better than during the first attempt, so I was able to get a mostly clear view of the launchpad and the rocket itself. However, being an evening launch with heavy clouds above still posed some challenges for getting good shots with my Nikon P1000. Fortunately, it worked out well for the most part and I could grab a nice still of the lift-off as you can see here.

The rocket soared through the sky mostly uneventfully while showing off the flames nicely as you can see here. Then Nuri disappeared into the clouds a mere minute later, so it wasn't possible to witness the stage separation. Still, people were happy to see a good, successful launch in person. I uploaded the recordings of the launch here.
