Nokia Lumia 1020 – Camera Image Quality

Detail and Basic Image Quality
Lumia 1020 cameraWith

a large 1/1.5-inch sensor, you’d expect the Nokia Lumia 1020 to come up

with excellent image quality. And, for the most part, it doesn’t

disappoint.

The Lumia 1020’s 34-megapixel images blow away the

competition in terms of the sheer amount of detail rendered (in good lighting).

Side-by-side, the Lumia shames the Galaxy S4 with incredible

reproduction of detail for a phone camera.

The Lumia 1020 also

has a very wide field of view when shooting in widescreen, with an

equivalent focal length of 25mm (in the 35mm standard measure). As

standard, the Pro camera mode created both 5-megapixel and 34-megapixel

images – the lower-res one shrinks the image while trying to retain as

much detail as possible.

Of

course, such a high-resolution camera sensor also helps to reveal the

deficiencies of the phone’s plastic lens. The Lumia 1020 has a decent

six-element lens, but the image gets very soft towards the outer edges

of the picture  – it’s only really the middle third of the frame that’s

particularly sharp. Towards the extreme edges of the photo there’s

flat-out distortion of objects.

This is only made

quite so obvious because of the high-grade sensor, though, and even

‘proper’ lenses suffer from this sort of softness at the edge of the

frame. So why are we mentioning it?

It affects the worth of the

recompose feature that’s a key draw of the Lumia 1020 camera – you can

‘reframe’ the 34-megapixel shot post-shoot, zooming in and rotating the

frame to produce a new fairly high-quality 5-megapixel one.

Having

soft-edged photos limits how much you’ll be able to zoom in without

seeming that you have done so in the final pic. But, still, it’s far

better than you’d get with just about any other phone camera.

In short, the Lumia 1020 is excellent in terms of the sheer amount of detail is can render when given a well-lit scene. For some photos taken by the pros, check out our page of pics taken by famous photographer David Bailey.

Low-light Performance and Flash
Is

the same true when the lights go down? Performance is well above

average, but for the best results you need to understand how the Lumia

1020 works.

The keys to low-light success with the Lumia 1020

are optical image stabilisation and the Xenon flash. Both can be used to

create much better-than-average shots in rubbish lighting.

First,

let’s tackle optical image stabilisation. The Lumia 1020’s lens

‘floats’, in that it can be tilted many times a second using tiny motors

that live in the phone’s camera housing. This lets the phone take sharp

(or relatively sharp) images using longer exposure times without using a

tripod. Using a non-OIS camera, you’d end up with a blurry mess, as

even a surgeon’s hands aren’t completely shake-free.

When

shooting static objects, the Lumia 1020’s stabilisation is excellent,

capable of making shots in mediocre lighting far less noisy and far less

washed-out than they would otherwise appear. When fiddling with the

shutter speed in the Pro Mode, we were quite amazed at how long an

exposure the Lumia 1020 can indulge in without becoming a blurry mess

(assuming you don’t have the DTs).

However,

when shooting people OIS is far less useful. A longer shutter speed

turns moving limbs into blurs. Unless your shots are entirely posed, OIS

does not result in good low-light photos of people.

Flash-less, low-light, sharp action shots are impossible unless you go full manual

That’s

why the flash is here. The Nokia Lumia 1020 has an exemplary flash

array – employing a ‘standard’ LED light to aid focusing in low lighting

and a powerful Xenon flash. Also known as ‘a proper flash’ around these

parts.

Xenon flashes are useless as a focusing aid because –

unlike LEDs – they cannot give off a constant stream of light but a

quick burst that lasts just a fraction of a second long. But why are

Xenon flashes better than LEDs? Much as other phone makers may say their

LEDs are on-par with Xenon flashes, there are significant benefits to

the Lumia 1020’s Xenon type.

It offers a far more even spread,

greater range and less of a tonally imbalancing effect than just about

any LED flash. It’s a reminder that LED flashes aren’t really flashes –

they’re torches.

There are some practical downsides to using a

Xenon, though. It’s far more power-hungry than an LED flash – one of the

reasons why Nokia produces a camera grip with an extra battery (around

£70) – and takes a short while to recharge. This compounds the issue of

the Lumia 1020’s relative camera sluggishness (in terms of shooting

performance, not focusing). 

The Nokia Lumia 1020 doesn’t like to compromise on photo quality, but there are sacrifices it has to make elsewhere.

Depth of Field

One

of the best reasons to have a good camera is to take arty-looking shots

that you can show off to your friends in order to look terribly clever

and talented. The easiest way to do this is with a shallow depth of

field shot.

This is where your foreground is in focus, but the

background is nice and blurry. That blurriness is known as bokeh, and

the Lumia 1020 isn’t too bad at making it. The level and quality of bokeh a

camera can create is based primarily on the camera’s lens, but the crop

factor of the camera’s sensor also affects it. 1020 vs HTC One

Comparing

the Lumia 1020 with the HTC One, it’s clear that the Nokia phone is

capable of creating superior shallow depth of field effect than its rivals. Forgetting

that the Lumia shot is both sharper and more vivid for a minute, the

plush toy is far blurrier, bringing out the squash bottle with far more

style. And yes, we probably need to invest in some more props.

Here are some quick shots of the shallow depth of field effect in action.

Macro

The

other top way to show off to your friends photographically is with a

macro shot – an extreme close-up that tries to offer as much fine detail

as possible.

Here the Nokia Lumia 1020 disappoints a little

because its focusing distance isn’t anything to crow about. Get the

camera any closer than about 13cm and it won’t be able to focus on a

subject – the wide angle 25mm focal length really doesn’t help here

either (making photos appear further away from the subject), and we were

left wishing we could get a few centimetres closer to the action.

However,

analyse your shots post-shoot and you’ll realise the high-quality

sensor does mitigate. You can’t get that close, but you can capture

some great detail without much effort.

VS a ‘Proper’ Camera

It

has its issues with shooting action sans-flash, and with shooting

speed. But the Lumia 1020 is a king among mobile phone cameras. However,

is it really a match for a ‘proper’ camera? The shot below (taken in a

near-pitch black room without flash) comparing the Lumia 1020 with the

CSC Sony NEX-5R, tells you all you need to know.

The answer? Not

up against an APS-C size sensor. But it has a good go – and it’ll

compete better with smaller-sensor cameras like the Pentax Q7 and Nikon

J3.

Panorama
There

are just a few extra Nokia Lumia 1020 camera bits to cover. Although

there’s no HDR mode built-in, you do get a Panorama ‘lens’. This isn’t a

special one made just for the phone’s high-end camera, and it’s not as

good as the iPhone 5’s full-resolution panorama mode.

It

captures the shot at severely reduced resolution, resulting in pretty

disappointing images. You’re probably best off manually stitching your

own panoramas if you’re looking for a shot of a landscape to treasure

and/or blow up, or looking for a better panorama Lens.

Video Capture
The Nokia Lumia 1020

isn’t at the cutting edge of headline features when it comes to video

capture. Phones are starting to incorporate 4K video capture, where the

1020 is stuck at plain old 1080p.

In reality, this is more than

enough, and the phone has far more worthwhile features. The best is

in-video optical image stabilisation.

The same lens motors that

eliminate the shaky-hand effect in photos are used in video, and they

eliminate the tremors that make handheld video look so amateurish. It

won’t perform miracles – jolts will still register as jolts and when

pushed the OIS can cause a screen tearing effect, but it increases the

quality of casually-taken video a good deal.

Front-facing camera
Front cameraThe Nokia Lumia 1020 doesn’t have an eye-catching front camera to match its rear, but it’s still above-average.

It’s

a slightly offset-from-centre 1.2-megapixel sensor that’s only really

there for selfies and video chat. It’ll record low-res stills and 720p

video too, though. Video quality is much, much softer than that taken

with the rear camera, but it’s far less noisy than it could have been.

Audio Capture
What’s

far more notable is the Lumia 1020’s audio capture. Like the Lumia 925

and Lumia 920, it uses stereo ‘HAAC’ microphones, which Nokia calls

‘Rich Recording’ mics.

Recording quality is good, but there’s no

magic ‘gating’ of recorded audio to block out unwanted ambient noise.

What it can do is record much louder audio than a normal phone without

distorting. Unfortunately we didn’t get a chance to record a gig with

the phone, but recordings in noisy environments like the London Tube

didn’t suffer from distortion.
