For the yearbook

Studio lighting mode.

After the test run the other day my son opted for the Studio Light portrait mode in the iPhone 11 Pro, donned a favorite shirt, combed his hair and voila! The shade of the orange tree makes for soft, diffuse lighting on what was a very sunny day. We only get 350 of those a year in Scottsdale.

iPhone 11 Pro snap, SOOC. The Portrait mode automatically blurs the background and the degree of blur can be changed in post processing.

Portrait modes in the iPhone 11

Stellar.

I have to submit a snap of my son for his senior yearbook, so we took five test shots using the iPhone 11 Pro using the various Portrait modes built into the camera:





Regular, Studio light, Contour light, Stage light Mono, High-key light Mono.

Amazing.

Post processing in Lightroom? Zilch.

Fifteen billion and perfect

Not to mention dirt cheap.

My nephew just picked of one of these 65″ LG LED televisions at Costco (Amazon asks a little more but no subscription is required):




Fifteen billion pixels. Click the image.

With a 4K display and a 120Hz rapid refresh rate and built in OS and cable accessibility, he paid all of $500. It may not be OLED but for $2000 less, who cares?

Now, I spent more time than I care to admit this summer with my son practicing SAT college entrance exam math, and can inform you that a 16:9 ratio display with a 65″ diagonal has dimensions of 56.652″ x 31.867″. Thank you, Pythagoras.

A square inch of a 4K TV contains 3840 x 2160 or 8.184 million pixels. That figures to 14.775 billion pixels in the display, and not a one can be faulty. Now that is what I call manufacturing prowess.

And the price is give-away cheap. At 47 lbs the display is easily wall mounted, to boot. The only challenge is finding space for this monster.

How wide is the iPhone UWA lens?

Incredibly so!

It’s not easy to convey just how wide the UWA in the iPhone 11 is. Apple states it’s 13mm FFE, so I decided to compare results with those from my Panasonic GX7 MFT body fitted with the 7.5mm MFT Rokinon fisheye (both now sold). As I have little interest in heavy spherical distortion (iPhone 11 UWA) or in the tedious fisheye effect (Rokinon), both images were corrected for linear projection, using my lens correction profile for the iPhone 11 (which reduces the FFE to some 14mm) and Fisheye Hemi for the Rokinon image. The defished Rokinon field of view computes to 12mm FFE.




GX7/Rokinon at left.

There’s much to be learned here. Both images were taken under identical fluorescent lighting with the cameras set to Auto White Balance. The Rokinon image is certainly 2mm or so wider, but there the Rokinon’s advantage ends. The iPhone does a superb job of auto white balance, rendering realistic daylight tones but, more importantly, take a look at the near cylinder on my classic BMW motorcycle. The dynamic range correction from the iPhone is superb. The MFT would need significant post processing to recover the shadows.

Except for distortion correction, both images are SOOC.

So yes, the UWA’s image is not quite as wide as that from a de-fished fisheye. But the advantage of the computational photography applied within the iPhone, which greatly enhances dynamic range, considerably outweighs the slight loss of width.

A tripod mount for the iPhone 11

Light, cheap and comes with a remote.

Amazon has these tripod mounts for iPhones under various names. I chose the cheapest, the Jansite, for all of $8.95. You can pay many times this sum if you like, which will make hipsters happy, but this does the job well for very little. The iPhone does not have to be removed from its protective case, and the tripod thread is the standard 1/4″ used on tripods since Henry Fox-Talbot was a boy.




There’s no need to remove the protective case.


The rear knob permits changes from landscape to portrait orientation.


I mate mine with an inexpensive, light Oben carbon fiber tripod which comes with a handy QR plate which is bolted to the Jansite tripod mount, and despite its light weight extends to some five and one half feet. The days of massive, heavy cantilevered Linhof monster tripods are over, and mine goes on sale as soon as I finish writing this. You do not need Brooklyn Bridge construction when your camera is almost weightless and comes with state-of-the-art image stabilization.

But wait! There’s more!




There’s a tiny button on the side of the remote for power. A blue LED confirms power-on.


The Jansite, for the crazy $8.95 outlay, comes with a bluetooth remote. This pairs with your iPhone in seconds (Settings->Bluetooth) and I gave up testing its range at 36 feet. So now you have the perfect night vision (Night Mode!) setup.

As for cases, hipsters will once again rejoice knowing their precious iPhone can be ensconced in $100 cases made from hides from select Schwabian bulls, but the $16 Lameeku provides all you need – decent protection for the triple lens assembly, a grippable leather exterior far superior to the slithery native surface of the iPhone and, best of all, room for the rest of your life in the slide out holder.




Your life in your pocket.

In my case that means a Driver’s License, a medical insurance card, an ATM card and a credit card. All you need. Were Apple Pay ubiquitous I would do without the credit card. And just like the hipster $100 special, this will last 2 years (as have my last three) before you need to upgrade it, not because it’s worn but rather because Apple has come up with some startling innovation in its latest iPhone and, naturally, that will not fit the old case.
