Isn't that tool available (at least in Adobe Illustrator) since 1995?

krikman: Article is total misunderstandig of light, mathemathics and photography concept.
Best possible dynamic rangre achieved with 1-bit image. There is absolute light and absolute darkness.
Adding more bit depths to image only increases number of possible colors between Blacks and whites of given picture, i.e number of colors and tones.

So you belive that 25 cm much longer than 10 inches?
Precision of your measurments never makes given lenght longer.
Full well capacity of сensor cell isn't directly related to digitizing depth.
Addition of extra precision units makes your measurments finer, leaving untouched total lenght. And if we have additional bits to digitize we got MORE COLORS with given DR. That's reversed to Butler's statement.

But these shadow enchancements (And highlight enchancement especially) have no couples to dynamic range but posterisation and tonal smoothness.
Peoples often confused by 2^n rule, where n="bith depth" and same time n="Dynamic range".

But if we talk about physycal difference, suppose that:
a) 1 kg * 2^10 = 1 metric tonn (10x dynamic range)
b) 1 kg / 2^10 = 1000 g (10x bit depth)

So you can measure your kg in any measurment (bit depth), it still be a 1 kg of weight (DR).

How to make a 9 minutes video clip and told nothing. This guy isn't journalist, He's just making selfie in style "Me and Eiffel tower", "Me and dangerous bee" etc.
Visual effects, great photographic skills, $100000 equipment and brave cameramen - all this ruined by film creation process.

fullstop: Looks as if DPR is expanding and moving away from being. still photographers site and is becoming more diverse ".........it is the only way to survive in this day and age

DPR made its reputation long before 2009. Barney, we all loved your pictures of Thames river. But for me you are a newly hired personell who take your own part in destroing DPReview as photo site. Now every small town on earth has its own entertainment website with tons of first-class local videos about anything. Trying to be Jack of All Trades, DPReview trips to nowhere.

Personally I love metal planes from Seattle like a 367-80, not plastic ones.

On article Google AI adds detail to low-resolution images (149 comments in total)
In reply to:

CQui: Ok, if I get it right, they feed the machine with the 8x8 thing on the left, get the 32x32 of the middle column out while a better resolution of the same pic was the right column...
How can they tell from the 8x8 the blob they start from is male of female?
How can they even guess it is a face?
Is there anyone at Google that believe this is more than just fake promotional sci-fi BS?

Basically All photo in social networks are:
Duckface
Cat face
or chew.

So AI can safely reconstruct these 3 objects from any pixel in photo with 99,99% probability.

Post any video of car crash.
(Imagine this is video)
This video is great reminder why you should not use public highways.

Focus isn't right on. And eyes too dark. Professional photojournalist would use fill flash.

Seems that this technology already implemented in news TV.

Kona Mike: Wow, Adobe is grasping at new features here. When added into Photoshop, it will be a gimmicky filter that adds to the menu bloat. Most likely it will only be used by 1% of the user base.

People pay for these upgrades, every month, forever?

Someday true AI will be invented. But that mighty AI will never like play chess or transform images. Nobody knows what that AI will want to do.

krikman: It uses a predefefined base of images "to look like". The firs real and useful purpose is a general photography:
Suppose you got this software in your smartphone with 10000 covers of fashion magasines as image bank. So every face will be slightly transformed to look more like a popular model.

It is total win, you just can't make an ugly photo of people!

Just load your image in databank, and all people will look as you. :)

Why not?

If Nikon copes with AF illness of their 55-x00 zooms, and holds IQ at least as 55-200VR I, it would be winnning occassionally telephoto zoom.

I've found answer. There was too much small pictures in original.

On article Primer: What is VR, and why should photographers care? (141 comments in total)

How do we, photographers, will sell these VR things?
Basically, they are just huge scanned massives of data for calculations. No photo work.

VR requirements is similar to scanning archieves in public libraries - hardly a piece or interest for photographer.

Sigma is well knowed for making stupid decisions for otherwise perfect cameras.

It is destiny. No cure will help.
