At the library

Not a right angle in sight.




The ultrawide optics does its thing.

My local library is one of those wildly abstract and severe designs which denies the existence of the ninety degree angle. This sort of architecture is fodder for the camera, as the above image discloses.

One of the complaints I have seen aimed at the ultrawide optic in the iPhone 11 and 11 Pro is that it is fixed focus. Such opinions are expressed by those with no training in the physics of photography. A 1.54mm focal length lens (13mm FFE) will render everything sharp all the time, as I illustrate here. There is no need for focusing. And if you want to change depth of field, Focos awaits. The other complaint is that saving the image in RAW format is not possible. Only compressed JPG is available. What this opinion denies is the extent to which computational photography and Apple’s always-on SmartHDR technology obviates the need for RAW. (RAW is available in some camera apps like Halide, not in the stock Camera app). Finally the third complaint – excessive lens distortion and vignetting – is justified, but easily resolved with one click in LR or PS or ACR using my lens correction profile. Apple’s claim that they left distortions uncorrected for the UWA lens to emphasize its ‘wideness’ is so much rot. They clearly rushed the product to market along with a disastrous series of iOS 13.x releases, each replete with bugs.

It is the small file sizes of JPGs for the UWA – and indeed JPG is standard for all three lenses – that is one of the unsung secrets of the camera’s design. As the data for the above image disclose, the RAW image is some 12mp (3024 x 4032 = 12.19 mp), whereas the JPG is a mere 2.88 mp. Now a file from your enormous Nikon D850 with its 50mp sensor and no less gargantuan optics will come in at some 150mp when converted to TIFF or PSD, which is what LR or PS has to do before you apply any processing corrections.




EXIF data for the above image.

And by contrast, so sophisticated is SmartHDR in the iPhone that those corrections are rarely called for. So suddenly LR performs once more like the spring chicken it once was, loading those 3mp files in a trice and creating full size previews in like time, whereas your D850 image dictates ever larger capital outlays on more storage, faster storage and improved GPUs. Why, process just seven of those images and there goes a gigabyte of storage …. And while you are processing all of those bytes, I have crafted a blog entry, written a suitably inflammatory narrative and am out on the street searching out new subjects for my camera. Plus, you are $5,000+ out of pocket and your shoulder is sore. I suffer from neither affliction.
