Will JPEGS ever be superseded by something better?

[The Masked Unit]

As a photographer it's such a disappointment to see the huge difference between looking at photos in Lightroom and the very same image in all it's compressed, degraded glory on Facebook and the like. Aren't jpegs just a hangover from the pre-broadband age and if so, when can we expect something that truly represents the full picture and can be hosted online?

[biggytitbo]

Compressed images are still really important on the web with the advent of mobile, so the battle has really been about better compression rather than better quality. Several vendors have had a go at it, notably jpeg xr in IE and webp in chrome, but they've not caught on due to not been widely enough supported.


If you really want the best quality and file size isn't an issue there is already a ubiquitous format for that - PNG 24.

Thanks biglet.

The PNG is my friend.  Not least because it's quicker to say.

My dad was one of the two representatives from Britain who set the international compression standards for JPEG. True factz.

He also helped design some integral part of the video phone, but turned down the offer to appear on 'It'll Never Work', for which I will never forgive him.[nb]Before anyone gets in with the obvious joke... the video phone did work and proved useful within sections of the deaf community for a short while, but it was very quickly superseded by the webcam.[/nb]

Did he provide the porno mag?

How's that? P-N-G - three syllables. J-PEG - two syllables.

[biggytitbo]

Its pronounced 'ping' though, which is 1 syllable!

[mook]

it's pronouced per-nee-ger.

[Blumf]

It's a shame MNG never took off

[mook]

got shit-canned after that rodney king bizzle

[Buttress]

JPEGs will soon be superseded by AJAX iframes embedded into a jar file (the wrapper of the basic Internet-to-Home-to-NSA package).

GIFs to be superseded by motion ASCII (hologramy enabled).

[glitch]

JPGa is already better than JPG but it was a Flash-only feature :v

[Hypodeemic Nerdle]

No, "pung."

[Cerys]

'Pung' would make more sense, because '!' is a ping.  It's too late, though.  'PNG' is automatically 'ping' for me.

Edit ... or is '!' 'pling'?

How does the Nikon raw format fit in? I just got a Nikon D810...

RAW files are essentially editable digital negatives, master files which jpegs, tiffs, PNGs are derived from.

To answer the OP, there is something called jpeg2000
http://en.m.wikipedia.org/wiki/JPEG_2000

Its beyond my knowledge as to why it never took off though.

[biggytitbo]

lack of support. I think only Safari supports it. Whereas only IE supports jpeg xr and only chrome supports webp. Come on guys!

Assuming you don't really know what a RAW file is, which is what it sounds like, I would suggest reading up on it before taking photos in that format, as you'll likely be very disappointed with the results (and in fact won't be able to view them without software that's capable of opening it).

[Pinball]

The Nikon is set to save each photo in both raw and JPEG formats. I find them hard to choose between quality-wise (viewed on an iMac), because the D810 is great quality.

When I was younger I was a keen photographer on a nice Olympus SLR (35mm film), and recently 'got serious' again with this digital SLR; prior to which, for many years, I just used good quality 'compact' cameras like Sony Cybershot that only save to JPEG.

So I'm currently learning, but want to use this nice equipment to the max! I'm on a steep learning curve, but hopefully not from a position of too much ignorance :-)

[biggytitbo]

Built into the jpeg standard is a lossless mode - but sadly its not widely supported. That leaves PNG 24 as the most widely supported lossless format.

[Pinball]

Presumably RAW format is lossless too?

Take a look at this Pinball, from page 3 in particular. http://www.adobe.com/digitalimag/pdfs/understanding_digitalrawcapture.pdf

Very useful- thanks! I'll keep the Nikon settings to RAW + JPEG for each photo.

[The Masked Unit]

Fair enough, but I'd say you ultimately want to be shooting RAW and processing your images yourself rather than letting the camera do it for you (no point having something as fantastic as a D810 otherwise). If you're not entirely sure why you'd want to do that, watching something like this would be a good start

Yes, ! is pling. (From the depths of my mind I'm remembering the command "!BOOT" pronounced "pling boot" which I think was a command on the BBC Micro, although I don't remember what the command was supposed to do.

[Cerys]

Presumably it was meant to be used as an alternative to an almighty kick up the processor when the machine was taking the piss.

Acorn Archimedes - a pling boot file in your application would be run when you double clicked the application.
May have been on beeb too.

Never heard it used outside that context though.

[Blumf]

The files were actually directories with all the executables, libs, images and other stuff in it, you could rename it (or something, I think it might have been some command line trick involved, been two decades) and diddle with the content. Was pretty neat, I liked RISCOS.



Also, most the time I see '!' being referred to as 'bang'. In *nix land shell scripts start with a sha-bang followed by the script engine to use (e.g. "#!/bin/sh")

Then there's the band, !!!, pronounced as Chk-chk-chk

Yup, I remember, just trying to keep it short. !icon was the icon for the app, and !something-or-other would be run when directory was shown, which my school used as rather shoddy security mechanism. Which could be overcome by hammering the escape key when opening the "protected" directory. I think you held down shift or something when double clicking on an application to open it's directory. Doesn't really work with shared libraries - although I'm not sure they had them anyway.
