Wanted: An Apple camera

The time is ripe.

I have yet to see anyone asking hard questions about where new product ideas came from at AAPL in the past decade. Did Steve Jobs wake up, shout Eureka! and conclude the world needed an iPad? I doubt it. Jobs was adept at looking at mass market products whose execution/UI were poor (PCs, the Walkman, cell phones, laptops, mobile devices) and making them better.

I have long argued that Apple should make a camera – look at the simply awful UIs of every camera out there. Knobs, button, horrendous software/menus, etc. The world needs a Wii-like camera, the ease of use of the one in the iPhone with a physical design that makes it easy to hold. Add in Siri and get rid of all those stupid buttons. Why shouldn’t you speak to your camera? “Use HDR in this one”. “Blur the background”. “Stop motion”. “Focus on the eyes”. And like other fields Apple has entered, with existing low margins and commodity characteristics (PCs, phones) there’s room for a premium offering which works better.

The current rumor, resurfacing again, has it that Apple should make a television set. A camera melds better with Apple’s business model which seeks to force upgrades every 2-3 years. That characteristic is completely absent from the television market where technological change has ceased and ‘brains’ can be added with the likes of an AppleTV at very low cost. And those ‘brains’ can be upgraded for $100 in 3 years’ time.

Digital idiocy. Today’s dinosaur, awaiting obsolescence – the DSLR.

In its thinking behind the design of the camera in the iPhone 4S Apple has clearly studied the needs of photographers. The outstandingly low shutter lag and inter-frame delay testify to the realization that not only sports shooters need those attributes. Mommy wanting to get little Johnny in the frame – rather than the background he has just vacated – spur the realization that the market for fast and responsive gear is anything but exclusively a professional one. Add in-camera HDR as the iPhone 4S does and one of the biggest drawbacks of the digital sensor is addressed – burned out highlights. But the 4S can only go so far. As a camera its ergonomics stink. As a design concept it has enormous promise. The five element lens is all plastic. That makes it light. I frankly don’t care what my lens is made of if its light, small and sharp. If it’s sharp because of software, that’s fine with me. If that same software confers limited depth of field that’s even better. ‘Fast’ lenses will soon be a thing of the past. All lenses will be ‘fast’ thanks to better sensors and better software. And, I’ll venture the guess, that’s also fine with all but the 0.1% of fetishists who get off on resolution charts.

What got me thinking about this topic yet again the other day was a silly little snap I took when getting the groceries:

Woof!

The car was turning the corner and the magnificent Standard Poodle was pretty much directing things through the sunroof. In a second the picture would be gone. I grabbed the 4S from the belt holster, made the camera live without by passing the lock screen (two stabs at the Home button) and the snap was in the bag. Now if Apple can do that in the crappy form factor of a cell phone, why not do it right with a dedicated camera?

C’mon Apple, photographers everywhere are waiting to be told they need to pay up for fast and simple.

Correcting verticals

A simple Photoshop routine.

The eye is exceptionally sensitive to parallelism and hence to leaning verticals. Hang a picture on the wall just a few minutes of arc out of level and anyone will spot the error immediately. Leaning verticals in photographs, where none are called for, are every bit as objectionable.

Correcting these is easy and better done in Photoshop than in Lightroom with its limited controls.

Click the picture for the instructional video and watch out for the phone call at the end! It seems that no matter how hard one tries to switch of all the sounds that pervade our lives, there’s always at least one sound source to be missed.

The Glif

A QR tripod mount for the iPhone 4/4S

Steve Jobs was right. ‘Simple is hard’, he said, when talking of sweating the details of a design. And, sadly, most of the accessory makers for the iPhone have tried for quick bucks and refused to sweat the details. ‘Think Different’, whatever the grammatical shortfallings of that mantra, is one foreign to their thinking, or lack thereof.

And so it is with tripod mounts. The plenitude of offerings out there is underwhelming to say the least. Most take the guise of snap-on backs or ugly straps which go across the face of the iPhone. But one, brought to us by the same funding mechanism which saw the outstanding success of the Luna-Tik iPod watch band, Kickstarter, really does Think Different.

The makers of the Glif had a similar success in raising capital for the funding of the injection molding process required to manufacture the device, though as I had decided to pass on the flawed iPhone 4 I had no interest in it. Now that the identically sized and shaped iPhone 4S is here with none of the antenna issues of the iPhone 4, I bought a Glif from Amazon and tried it out.

Suffice it to say that this is the iPhone tripod mount for thinking people. Small, light, take-anywhere and superbly functional, you can see it in use below.

The Glif can also function as an iPhone support, so check their site if eyestrain is your thing.

The Glif holds the iPhone securely and shaking it as hard as I could I was unable to make it part company with the iPhone. A GorillaPod would make a perfect mobile tripod accessory for the Glif. Until now I have resisted buying one as it just seems too flimsy for even a small DSLR. But given the iPhone’s low weight, the GorillaPod will likely be finding a home here soon.

For taking movies just start the movie from the iPhone. For still shots, as there is no remote release available for the iPhone making the likelihood of camera shake higher, blow $0.99 on the Camera+ iPhone app which includes a nice self timer. Touch the self timer screen and it switches between 5, 15 and 30 seconds.

Bertie poses for Camera+ with its self timer.

More importantly, if you are into the whole ‘lone figure in the landscape’ thing, the self timer is just what the doctor ordered when you have to be the model.

If you use a screen protector or a case or some other encumbrance on your iPhone, forget it. The Glif is not for you.

iPhone 5 update: When Apple came out with its toy-like iPhone 5, a device whose flimsy feel and compromised assembly (uneven seams in mine) does not remotely live up to that of the 4/4S, it also made the phone thinner, rendering the above Glif useless. There’s now a slimmer model available for the iPhone 5 and it works just as well.

Background Blur

Making the subject pop.

I have referred to the need to blur backgrounds in pictures made with short focal length lenses often. As cameras get smaller, focal lengths shorten. The 35mm FFE lens in the iPhone 4S, for example, has a focal length of but 4.3mm, meaning just about everything is always sharp. At a given aperture, depth of field is solely a function of focal length, having nothing to do with sensor size.

To put this in perspective, the 50mm FFE lens on a full frame 35mm camera or DSLR become 150mm on a 4″ x 5″ sheet film monster, 80mm on a 6×6 medium format Hasselblad, 25mm on an MFT body and just 6 mm on the typical cell phone with its microscopic sensor. Compared to a 6mm, the depth of field of a 150mm lens is miniscule – everything is in focus with the former, little is with the latter. So selective focus on small cameras, absent help from software, is not going to happen ‘in camera’, yet.

If a picture is worth a thousand words an instructional video is an order of magnitude more efficient, so I have made a brief video explaining how to confer background blur using Photoshop CS5, which you can see by clicking the image below. While I start and end the process in Lightroom3, that’s not a required part of the workflow. Use whatever database you like for storage.

And remember, the only people who will know you used this technique will be those you tell in advance.

One day this technology will be built into software in cameras. The user will be able to restrict the zone of sharpness to the main subject. Cameras already have face recognition. Selective focus is a rational extension of this thinking. Meanwhile, PS CS5 does just fine.

The iPhone 4S does San Francisco

How good a street snapper is it?

Test charts never did cut it for this street snapper. Real world use and responsiveness turn my crank. So, with that view in mind, I ventured to SF from the south bay, the iPhone 4S’s hotspot providing wifi for the iPad so that I could do my day job on the train there and back.

The iPhone is not going to win any prizes for ergonomics and, frustratingly, I found myself activating the movie slider on more than one occasion until I got the hang of how to hold the gadget right, neither going into movie mode or obscuring the lens. I learned to hold it in the left hand just so, with the camera on, and it was then easy to raise to face level, squint and shoot. I used the Volume ‘+’ button for the shutter release, in preference to the awful touch button on the screen which is an ergonomic nightmare.

What made the whole experience a (relative) joy is the responsiveness of the shutter release which has minimum delay and short time between snaps. Just for fun I tried to see how fast I could shoot and managed 24 snaps in 15 seconds, without trying too hard. Not half bad! Those were all garbage of course, as is typical for machine gun shooting. But one or two others worked out, helped by the strange unobtrusiveness of the iPhone, as your subjects think you are messing with a phone rather than taking their picture. In many respects, now that it has a half-decent camera, the iPhone 4S is the least obtrusive street snapper I have used. As a matter of interest, I consistently found portrait orientation easier than landscape.

Where you see blurred backgrounds they are courtesy of Photoshop CS5 and those thinking of writing me about bokeh or some such nonsense should spare themselves the effort. Bottom line, post processing blur works and it works superbly. It’s hard to relate with a straight face but there are dorks out there who get off on studying the unsharp bits ….

The iPhone has got what it takes for street snaps and not too many excuses are called for.

Some of the above were processed lightly in LR3 with background blur added in PS CS5.

Lunch after all this exertion? Why at the South Park Cafe of course!

Pork, dates, a rich sauce and mash. iPad testifies that this was a deductible business trip! Mmmm!
