Upcoming deaths

iPhone, Photography

All change.

Here are some of the activities and businesses which will die with the oncoming tsunami of change powered by computational photography:

  • Professional wedding photographers – anyone can take a good wedding snap, and it only has a shelf life through the divorce date
  • Micro Four-Thirds cameras and lenses – they add nothing to iPhone 11 Pro quality at 4x the bulk and weight
  • Olympus – all their eggs in one basket …. and a handful of microscope sales and accounting fraud
  • Nikon – no diversification
  • Canon’s big gear division
  • Panasonic’s camera division – they managed to deliver a great FF body just as the format died. They should stick to TVs and washing machines
  • Pentax – no distinguishing product
  • APS-C – a ridiculous format which delivers the quality of MFT in the bulk of FF
  • All those silly-priced Zeiss lenses for full frame
  • The third rate garbage that goes by the moniker ‘Sigma lens’, an oxymoron if there ever was one
  • Most large format digital – silly priced, no quality advantage over big sensor digital bodies
  • Sony’s camera division. On the other hand their cell phone lens and sensor division will bloom
  • The last handful of reportage pros – everyone has a camera and the pro will never be in the right place at the right time
  • The mystique associated with ‘pro’ gear. It’s inferior in most practical aspects to the best cell phone cameras
  • DP Review – how many cell phone reviews can you do in a year?
  • All the other hardware sites for pixel peekers

Leica, however, will survive as there are always antiquarians with china cabinets to fill.

And it’s all because of this little part with 8.5 billion transistors in the area of two postage stamps, plus a team of very smart programmers:

And by the time Samsung has managed to steal all this proprietary technology, Apple will be on the A20. I provided an early peek inside Samsung’s design lab almost a decade ago.

For the yearbook

iPhone, Photographs

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.

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

Hardware

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?

iPad, Micro Four-Thirds, Photography

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.
