Comments on: Turf war between Microsoft's JPEG XR and Adobe's DNG?

JPEG XR has features that appeal to advanced amateur photographers who use raw today and whom Adobe is courting for Digital Negative.

JPEG XR might be the future

First of all, with digital cameras today, people have an LCD screen to see shots after they take them, and if someone's face is in the dark, they just re-take the shot. With the gigabytes on SD memory cards today, people with a digital camera can afford to take more than 1 shot of every scene. I can store more than hundreds of photos, and practically an unlimited amount if you swap memory cards.

Second of all, like the CNET blog said, people don't like processing time. They want to be able to show, edit, and email their pictures instantly. If the quality and small footprint (size) of Microsoft's new JPEG XR is true, then it might be a winner for an evolved JPEG format. Also, given the fact that the JPEG name is popular and widely-known, it wouldn't hinder Microsoft's marketing efforts unless they are really stupid.

PNG?

How open will this standard be? If I find that any part of it requires proprietary code, then screw it all.

True openness is key. But then, Microsoft seems to be getting better at that.

CNET's Confrontation Hype

I know the news business does better with confrontational stories, but there is no battle here. DNG and HD Photo are designed for two entirely different purposes.

DNG is a well specified format for storing raw sensor data from cameras. HD Photo is a format for specifying compressed high bit depth images (which JPEG can't do) after they have been demosaiced and had adjustments and white balance applied. It's apples versus oranges.

I would gladly enjoy a camera that could produce both, but for different reasons. HD Photo can be a great successor to JPEG, DNG cannot be a JPEG successor because it serves an entirely different process.

Please do more research before writing articles such as this. The other article on HD Photo helping out Vista sales is also misleading. HD Photo works just as well on XP with the appropriate software. There's nothing special about Vista's support for HD Photo.

reporter responds: it's not hype

I think your comment is a bit unfair. For one thing, I included the points you raised about the separate features of DNG and of JPEG XR/HD Photo. For another, I specifically said "I suspect the two formats will remain more in separate domains." So I'm not sure what more research would be warranted here.

But I do think there's some overlap, especially in the future, since Adobe wants raw and DNG to spread more broadly into the very zone that Microsoft sees appeal for JPEG XR.

It's Microsoft's opinion, not my own, that HD Photo/JPEG XR will help Vista's prospects. Regarding Windows, XP can handle HD Photo, but you have to find, download and install the support yourself.

Another story you might want to look at (http://news.com.com/2100-1045_3-6153730.html) makes the point that Vista will help HD Photo (not the other way around).

Scarce HDR support

Well, apparently HDR support in HD Photo came out quite poor.

...clearly there's something better around already...and it's Jpeg-compatible.

A Review02

I know very well that car maintenance is the first concern for the car buyers. Whether you own a sedan car, SUV, sports car or a luxury vehicle you would normally seek assurance that car parts, its exterior and interior accessories, body kits, car spoilers, billet grilles, wheels, rims etc are freely available. Toyota, Nissan, Honda, General Motors, BMW, Ford and many car manufacturers have taken care of this need of their customers. While purchasing car parts price of the OEM car parts has always been as issue. High priced car parts scare away the car parts buyers in spite of the fact the OEM car parts offer reasonable duration of warranty and after sales service and replacement options. Buying of aftermarket car parts, on the hand, is a very good option. The low priced aftermarket car part, acura brake pads - billet grille; car spoilers have extended ease to the buyers. They can no buy Volvo Cornering Light for the sake of maintaining their cars and obtaining a longer useful service.
