h2k: "There are a lot of advantages to the HEIC format"
---
And i have a lot of prejudices against storing my snaps in an Apple format - and against converting my snaps via web upload. Who'd do this?

It's based on the video compression standard HEVC from the MPEG group, also known as H.265 or MPEG-H Part 2. Samsung adopted it for their NX1 camera, DJI are using it for their drone video, and Nokia are involved in various was too.

Decoding is built into most recent 4K smart TVs from Sony, Samsung, LG etc.

It's just a much superior format, so Apple have decided to adopt it.

The standard allows for the file to contain a collection of related images, for example, a copy of the raw and a copy of the processed image, or a sequence from a focus stack that can be used to refocus the image interactively, or a very large panorama and hi res images tiles that map into the panorama so you can just keep zooming in and zooming in and keep seeing finer and finer details.

And much more.

NJOceanView: This is helpful -- thanks. I also understand that a Settings option will allow you to continue to save your photos as traditional JPEGs, which is what I will do as I dump my photos off my phone frequently enough to not have an issue with it.

I haven't seen that explicitly stated yet but heard conflicting reports, some to the same effect (the dependencies are a bit complicated). However, I'm pretty sure, at least if my understanding of some of the developer conference sessions is right, that decode is supported, so the encode can still be done in software by 3rd party apps, and the files will be supported. But I agree it's been hard getting clear cut facts on some of the details.

If you have and good technical links you could share, I'd be grateful.

In reply to:

BRPWS: is this new format also bringing in raw files and changing them the new format? If so how is the raw file itself protected or is it simply destroyed?

No. If you choose to shoot raw you get the raw.

If you choose to shoot JPG, then like every camera, the camera processes the raw and saves just the JPG.

Only now, if you choose to shoot HEIF, the camera processes the raw and just saves the HEIF, exactly the same except the file size will be smaller so the phone won't fill up as fast.

If you choose to shoot HEIF (higher quality / HDR) then the raw will be processed into a higher quality 10 bit file and that will be saved.

If you shoot raw+jpg or raw+HEIF then both will be saved.

We will have to see when the dust settles on the final release as to which features will be available natively and which will need to use 3rd party camera apps.

Good luck Apple.

This is a brave move and one many photographers will eventually thank you for when all the flack has died down (and boy will there be flack, lol).

I'm really looking forward to saying goodbye to 8 bit color and hello to higher quality 10bit color. I just hope camera makers are fast to realize this and the many other benefits it brings and get on board sooner rather than later.

melgross: From what Apple has said, if sending images to those that can’t use this, it will convert them to jpegs, using Apple’s proprietary conversion algorithms.

That means that this isn’t really needed.

Yes, we will need to see how it all plays out in reality, most things should have been thought through and catered for (lol, famous last words) but it certainly doesn't hurt to have a free conversion option available in case it is needed for any reason.

You might want to reconsider that at some point. While one use of HEIF is to use more efficient compression to store an image in a smaller file, another use of HEIF is to instead use that saved space to keep a higher quality file using approximately the same space as a regular JPEG.

These higher quality files have 10bit color data rather than the 8 bit used for JPEG. As a photographer, this is the aspect of HEIF that really excites me.

In reply to:

FasterQuieter: Isn't it supposed to be Heif, pronounced heef? I keep seeing Heic now and it is getting confusing.

HEIF (being promoted as pronounced heef) is the name of the specification for the format, High Efficiency Image File format.

HEIC is the file type that people still using file systems will see when they see the file name. For example IMG1234.heic

Think of it like a JPEG file with a name IMG1234.JPG. JPEG is the specification for the format and .JPG was the original file type back when tile type extensions were only 3 letters and upper case. On later file systems .jpg and .jpeg could be used interchangeably.

In reply to:

Alphaville: Will the existing photos in the phone also be converted to HEIC format?

No, only new photos to start with.

But any old photos you edit will generate the edited copies in the new format and you'll get the space saving benefit from that (iOS never changes your originals so edited images are stored as a 2nd copy and the original is hidden unless you choose to revert to the original).

Many options will likely spring up very quickly to convert, but no doubt the wording will be very scary as it will essentially be creating a new version and then deleting the old one. That 'deleting the old one' part will no doubt turn into billions of varieties of disinformation, lol.

PhotoKhan: This "innovation" need that almost sounds like a techno-junkie request for a regular fix is utterly strange and the true sign of our hedonist, purposeless times. It goes so well hand-in-hand with current-day politics.

As for Canon-as-a-target, it is true their are not the most innovative, at the moment, but they do have other advantages. as a Photography brand.

In any case, it is all a moot point, as the real driving factor is Canon being a brand that attracts so many criticism and hate, it is almost a case study.

If Canon was "innovating" on a weekly basis, the very same people would be complaining how they couldn't keep up with such fast-paced change and how it was shame Canon lost their "spirit" or whatever...

Nice, but naive and utopian.

Way before digital cameras gained any traction, before Kodak hacked a Nikon body to add a 1mp sensor, selling it for the price of a nice house, a cool $25,000, video was king, and computers.

I videoed friends weddings, and used my Amiga to add mind blowing page curls that took 24 hours to render for a single page curl, and the production required special hardware called genlocks and frame grabbers.

Video has always been specialist, a labour of love, and a team sport. Good video needs sound, lighting, editing, actors, stories, and tons of storage and computing power. They don't even call the camera guy a photographer, he's a cameraman.

When DPR make a headline proclaiming the EOS M5 a 'disappointment' because it doesn't have 4K video, I despair at any chance the average consumer has to inform themselves.

They are having disinformation rammed down their throat, with headlines saying "you need this".

I fear most are becoming only more disinformed.

If you put every feature into a camera, you would have only one camera and it would cost a packet. But that's not how it works, different features get put into bodies for different target customers.

My issues are in the appropriate choice of features. I think Canon make good ones, whereas Olympus make questionable ones.

I don't think M43 sensors have advanced to a stage where they can ration the slightly better IQ of the 20MP sony sensor. And good fast AF is now a basic photographic feature.

I'm not saying I'm right, that my choices have to be obeyed, let the market decide. To my mind, Canon has a better read on the market (though clearly not the Internet forums, lol).

notpc, is that the scale of your gamut? Black and white, with no shades of grey. An innovation demander or a corporate apologist turd?

You make me feel schizophrenic.

I'm frequently at war in the M43 forum, where potentially great enthusiasts cameras are released with aging sensors and inadequate focusing technology, and these CATs (as you so eloquently put it) defend Olympus claiming it's unreasonable to expect excellent sensors and proper AF in $600-1000 cameras, despite every other manufacturer offering precisely that. I'm an innovation demander!

But I can't find the effort to get het up about Canon. Even the 6D.2 everyone is puking over seems like a great camera to me. But I'm not into pretending to be a 4K videographer, and if it only has DR suitable for 98% of my anticipated shooting needs, then it already soared way past my pass mark. So I guess that makes me a cool CAT too right.

Essential Duality, the only way for me.

Talk is cheap, talk is trash, dangerous and powerful. Talk is these and more. The way we talk exerts influence on those who listen.

Starstruck groupies and fans behave in a way that is known as 'affected'. The realities in their head are out of balance with the physical realities of the world they inhabit. The 'high' side effect of excessive influence.

But in the internet world, influence is pay and in the dog eat dog arena of the blogosphere the fight, is to be heard. To be unheard is to be unpaid and to cease to be.

So the bloggers, like master chefs, must take bland raw ingredients add a little sugar and spice to transform the bland into the sensational.

Bland increments don't have the click power of the promise of a game changer, so the required spice becomes to attack the absence of a game changer.

In case anyone missed it, the game changer was the smartphone. And yes, Smartphones, and even Canons, can be used for producing insanely good photos.

How bland.

Najinsky: Vision over profit is an idea I can (and do) get behind, but in over 40 years as a Sony customer I only ever found they are so much closer to the bottom of the pile than the top, that this item instinctively makes me want to vomit.

This is the company that brought you this:

https://en.m.wikipedia.org/wiki/Sony_BMG_copy_protection_rootkit_scandal

On a more positive note, despite an excessively long term campaign of disinformation against companies who have genuinely advocated a long term vision, Apple being the most successful example, if this is real, it can only be good to see more companies adopt this 'if you can't beat them, join them' approach. We will all gain in the long run, whether we like it or not. A bit like being weened off our security blanket, or milk.

@EthanP99: "Oh, you still on that rootkit thing again? talk about not letting things go."

What do you mean 'again' ?

Are you simply confusing me with someone else, or is this a deliberate attempt to inject a false narrative to try to deflect from Sony's unfortunate history of getting caught playing fast and loose with consumers rights?

I hope it's the former, because if it's the latter then, ewwww, that would be nasty, very nasty and pretty scumbaggy.

Presumably if you are suggesting it's neither, you will no doubt have many links to rootkit posts demonstrating the obsession claimed in your alternative narrative. So let's 'ave 'em.

In reply to:

Richard Murdey: Isn't the point though that for 12 bit, the lower light ranges are encoded at very poor resolution, say from 8 to 16, i.e. 8 steps for 1 EV change in light intensity, whereas for 14 bit that same range of light intensity would be encoded from (using your diagram above) using the range from 32-64, i.e. 32 steps or 4x the "smoothness" of the gradation?

That's why 12 bit looks so often more pixellated on very gradual color transitions.

That always seemed the reasonable explanation to me.

@Mike thanks for posting this. This is the train of thought I've been struggling to lock my head onto and your post finally got it there. But now it's there, it's not clear where this train takes me!

In reply to:

thx1138: So I checked the patents and the 50mm lens is around 257mm long, or longer than my 300 f/2.8L IS, now that is simply ludicrous, even Sigma would blush.

@russbarnes. What point are you trying to make?

Thx has shown figures from the linked embodiment that shows total length of 256.8 (presumably millimeters).

Just saying he is wrong and saying read it again is useless and annoying. Anyone who looks can see that is the figure given.

The only way you can say he is wrong is if you actually know a different figure for the total length.

So why don't you start by telling us what the real length is, and where you got it from?

Man that 50/0.9 design looks like an expensive chunk of glass. Guess they're going to be competing with Sony A9, and maybe make people think twice about moving to a Hassleblad/Fujifilm MF system.

On article Olympus OM-D E-M10 Mark III Review (564 comments in total)
In reply to:

Marty4650: This camera isn't designed to be an upgrade from the EM10 II.

This is just a tweaked, refreshed and improved version of the EM10 II. No one in his right mind would upgrade from the Mk II to the Mk III. However, it now becomes more attractive to first time M4/3 buyers moving up from smartphones, or sideways from other camera brands.

@NowHearThis

I have contemplated the Pen-F many times, and still occasionally do. To my eye, from the IQ in the DPR studio scene, it seems to be best rendering of any of the 20MP M43 sensors, but the differences are so small as to have little meaning. The Pen-F would certainly deliver a small boost over my EM5 IQ, and it has the hi-res mode that would be useful for some fine art reproduction projects I do. And this is what draws me to it.

One thing that turns me off is the rangefinder style. I don't like the side placement of the viewfinder in general, and when I put a longer lens on for wildlife, I feel a centrally located finder is essential, as is a proper grip.

But mostly it's about AF.

In every other system, what differentiates entry level from enthusiast and on to pro, is sophistication and utility, but even entry level is now endowed proper AF.

If Olympus insist on me having to buy a pro level system to get fast working AF, my response is simply to buy a different system.
