Image Quality and Imagination

17 09 2017

High-dynamic-range imaging (HDRI) reproduces a greater dynamic range of luminosity which is nearer to the range of luminance experienced through the human visual system. The human eye, through adaptation of the iris and other methods, adjusts constantly to adapt to a broad range of luminance present in the environment. The brain continuously interprets this information so that a viewer can see in a wide range of light conditions.

According to Apple’s Human Interface Guidelines, the larger 42mm Apple Watch has a resolution of 312 x 390 pixel at 326 ppi. The iPhone 6s Plus Retina HD display has a 5.5-inch (diagonal) with a screen resolution of 1920 x 1080 pixel resolution at 401 ppi.

The collage shows zoomed parts of the original image (taken with the iPhone 6s Plus) on the iPhone and the Watch.

The  Watch has a small screen with a limited resolution but I still like it for seamlessly looking at some images of my family, especially my grandchild, wherever I am and whenever I want.

People might say that the quality is poor but in my opinion it’s not the quality of an image but the related imagination which provokes the emotion you are looking for when viewing images. A lack in image quality will be compensated by a considerable increase in imagination.

There is no need to pull out its big brother. Sometimes I also use one of the images stored on my  Watch as a watch face to have that hearty laugh of my young grandchild right on my wrist.

TrueDepth Camera System

16 09 2017

Apple calls its new biometric identification system for the human face Face ID.

(Source Apple)

It’s made possible by an all new TrueDepth front-facing camera system, one of the most intriguing features of Apple’s new flagship iPhone X.

In my opinion they didn’t make it right with replacing Touch ID instead of adding Face ID to Touch ID. There are lots of use cases where Face ID or Touch ID cannot be applied and so users have to go back to the inconvenient entry of a passcode. I predict the return of Touch ID when the technical problems of integrating Touch ID into the all new OLED display will be solved.

But be careful when you take photos of small dragons like the Tokay Gecko. I caught him after he tried to break into our bedroom. He’s able to bite off a piece of your finger.

iPhone Cameras

Are you waiting for Tim Cook on stage this fall?

Well, maybe you don't wait for the next iterations of Steve's masterpiece (allegedly the 7s, 7s Plus, and the 8) but for a good price for some predecessors, the

iPhone 7/7 Plus 6s/6s Plus SE

with great cameras.

Resolution …

All these models have 12-megapixel rear cameras, but there is a meaningful difference in the front-facing camera resolution. The iPhone 7 and 7 Plus have a sharp 7-megapixel camera; the 6S and 6S Plus have a decent 5-megapixels; the iPhone SE can only offer a grainy 1.2-megapixel selfie experience.

Aperture …

Apple followed an industry trend and made the rear-facing camera aperture larger (iPhone 7/7 Plus f/1.8 and iPhone 6s/6s Plus/SE f/2.2). The larger aperture means more light can get to the imaging sensor, for better captures in different levels of light.

Optical Image Stabilization …

OIS technology keeps your captures still even when your hands are shaky. It's fairly common in Android phones, but as far as iPhones go, it's only found in the 6S Plus and the series 7 phones.

Optical Zoom …

Only the iPhone 7 Plus has a dual-lens camera with optical zoom and improved digital zoom. It lets you take sharper pictures, from farther away. The rest of the iPhones, like most smartphones, are restricted to digital zoom only (which is really just a type of image cropping).

Flash Type …

The flash on iPhone 7 and 7 Plus has been updated from a dual LED to a quad LED. The newer flash does seem to improve tonal range and decrease unwanted contrast.

My recommendation …
if you're still on a 4S, 5, or 5S

Buy a 7 Plus and take a lot of great shots.

I don't buy a new device because I disagree with

"It’s easy. Just trade in your eligible smartphone, and then use the credit to lower the full cost of a new iPhone or to reduce the monthly payments with your carrier."

(Apple on iphone/trade-up)

What's your take Lisa Jackson as the VP of Environment at Apple Inc?

My 6S Plus makes great shots, right?

No need to let the mining machines in the Democratic Republic of Congo go for Tantalite for a new device.

Holy Lens

10 07 2017

Relatives came to visit us today with this car. You won’t believe it but these cars get car licenses in Thailand. They are far away from any safety requirements or even self-driving cars which are one of the main technological areas where researches and developments are done, not only in the epicenter of car technology (southern Germany) but also in Cupertino. But there is no chance to connect your iPhone via Bluetooth or even get Apple’s CarPlay running for these dinos.

I took this shot with my iPhone 6S Plus.


It shows the performance of Apple’s rear cameras. But there is still room for improving shots with specialized accessories.

iPhone’s Camera

iPhone’s Camera …
a shining example for silent innovation

I took this shot with my iPhone 6S Plus in Ban Dong Pong, a small village near Khon Kaen, Thailand, where I retired last year. It shows an ISUZU truck for carrying rice harvesting machines (or Apple’s iCar to keep project Titan top secret?).

The problem with too much megapixels

The iPhone 6S and 6S Plus came with 12-megapixel rear-facing cameras, a major improvement over the 8-megapixel cameras from recent years.

Images now pack 50% more pixels than before so you can see more details, and you also get 50% more “focus pixels” than in the previous iPhones for faster auto-focus.

Cameras with more megapixels usually sacrifice image quality in certain ways. Normally when you pack so many pixels so close together, it creates artifacts called “crosstalk”: inaccurate colors and noise in your images.

Apple’s team worked on new techniques to maintain image quality and size despite the extra megapixels, including a technology called deep-trench isolation, which separates photo diodes and helps to maintain accurate, precise colors.

iPhoneography

19 03 2017

It was 42C / 108F when I took this photo with my iPhone 6S Plus.

Well done iPhone. Shortly before I took the photo my device stopped working but came back to life after removing Apple’s Silicon Case which seems to hamper heat dissipation.

About the image
Wat Phra That Phanom is the sacred precinct of the Phra That Phanom chedi, located in the Nakhon Phanom Province, Thailand. According to legend, this structure contains The Buddha’s breast bone, and as such, it is one of the most important Theravada Buddhist structures in the region.
