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.

Ford vs. Ferrari

Race movie, sort of.




The insipid poster for the movie.

The early 1960s long distance racing scene was dominated by Ferrari’s wonderful 4 liter mid-engined V12 motor. A small, high revving engineering masterpiece it was set in bodies that only the descendants of Michelangelo could create. It won everything in sight.

However, during the early part of the decade, a drunken philanderer who had chosen his parents well, one Henry Ford II, decided that “Win on Sunday, Sell on Monday” would work for the Ford Corporation and set to doing it the easy way. He would simply buy Ferrari and change the prancing horse on the hood to the familiar blue lozenge. No deal. The Commendatore was not about to yield his name to the crass vulgarian from across the pond.

So Ford had to make his own and did it the American way. He threw money at it. The car was large, the engine a crude, low revving 7 liter monster. A few million dollars later all Henry II had to show for the almighty American dollar was a bunch of egg on his face. The cars failed for every reason known – blown brakes, a gearbox made of cheese, awful aerodynamics and even overheating monster motors. The drivers needed work, too. Then Ford chanced on the greatest development engineer and driver of the decade, the Englishman Ken Miles, and the car started to take race shape. After more millions the Ford GT40s came in, line astern, at the 1966 Le Mans race, 1-2-3, and kept winning through 1969 when Porsche finally decided to show them what is what and who is who. Miles never won the Le Mans race and the movie goes on and on about how he was ‘robbed’ by the suits from Detroit who wanted a Real American at the wheel, which is ridiculous when you realize the winning car was driven by an Aussie and a Kiwi. The line astern stunt relegated him to second, for he had traveled a few yards less than the ‘winner’, though he was the fastest driver by a country mile (actually 3 miles as he was a lap ahead before being ordered to slow down). Vive La France!

The movie commits the usual Hollywood faux pas of trying to interject family relationships into car racing. Do we really care that Miles’s wife was a shrew from the Midlands? Or do we want to see cars racing? And that’s what makes this a far weaker racing movie than Steve McQueen’s ‘Le Mans’ which documents the Porsche 917’s win at the 1970 race, driven by an Englishman and a German. The best thing about the new movie, as is the case whenever he stars in a film, is the Welshman Christian Bale, doing a great Birmingham accent. The worst is Matt Damon, if you even notice his mechanical acting, that is. A truly underwhelming, if bankable, ‘star’.

The McQueen movie failed as there was insufficient audience for what is a pure racing movie, the best ever. Ford vs. Ferrari will fail because of awful marketing and a poorly developed script. And, well, it was so long ago who cares? This is, after all, the land of short attention spans.

But for the true motorhead it’s worth catching. Just try to do so at an IMAX theater for maximum visual and aural effect and close your eyes and ears when the shrew is on the screen.

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.
