Lytro – revolucija fotografije?

Neka, meni se svidja ;)

Iako, 2.5 tisucice...

Lytro aparat sa kasnije podesivim fokusom je doista:

Nije tako lako uhvatiti cijelo svjetlosno polje, pa zato su slike male rezolucije jer senzor mora snimiti sve uvjete. Od nečega se i mora početi, pa će valjda u budućnosti biti bolje.

Jest, ali samo doređene dođu do leće ovisno o ekspoziciji i ostalim uvjetima. Ovdje odabereš uvjete koji ti odgovaraju.

Koliko znam, slike na njihovoj stranici redovito imaju do 4 različite dubinske oštrine, ne neograničeno mnogo.

Ako kamera zaista u ~u istom trenutku fotografira nekoliko fotografija različitih "točaka fokusa" - to ne vodi nikamo. Ne može kamera odrediti 4 točke fokusa koje su meni bitne na fotografiji.

Ako je tako, bolje da se fotografira jedna fotografija sa malenim otvorom blende + da se nekim laser scannerom odredi udaljenost objekata u isto vrijeme. Onda bi računalom mogli izoštriti / zamutiti absolutno svaki dio fotografije.

  Nije mi jasno ovo.

Zar ljudi nikada nisu koristili fotoaparate? Fotografiraš gomilu sa običnim fotoaparatom sa malim otvorom blende (visoki f) i svako lice je oštro.

jep i uzasno mala reozucija slike ove vijesti na naslovnici :( ,a vece nema u samoj vijesti 

Tehnologija je smeće i neće nikad zaživjeti zbog fizičkih ograničenja koja postoje od samih početaka fotografije.

Mogu za 2000kn kupiti polovni dslr i objektiv i raditi 100 puta kvalitetnije fotke nego što će ovo ikada moći.

I kao što je DrNasty rekao, ne želim još više vremena provoditi na kompu s fotkama nego što ionako provodim.

ovo biće radi na šemu da uslika velik broj slika i kasnije posebnim formatom daje kao da je jedna i imaš mogićnost fokusiranja tj. biranja različitih sličica u različitim fokusima... mislim da ovo neće zaživjet.. a i nepraktično izgleda, ovo nema šanse da zamjeni DSLR a nit kompaktne..

Bacio sam pogled na dpreview, navodno fotka ide zajedno sa engineom kad se uploada negdje, pa svako onda može fokusirati po želji.

Evo šta Thom Hogan misli:

What's missing in the details are a couple of things: angle of view of the lens, the number of focus zones, and the final pixel count of the images. What we get instead is a new marketing term: 11 Megarays. What that means in real pixels is currently unknown, but my best guess so far is something like 8 focus zones at a resolution of maybe 720x720 pixels.

Wait a second, what's a focus zone? Well, the way a Light Field camera works is by collecting information about how the light gets to the final sensor. A microlens set far forward of the sensor is the primary manner in which that information is obtained. But it means that you have multiple photosites on the sensor that are getting information from a microlens. The number of photosites that collect a microlenses information determines how many light angles you capture, and that number will determine how many discrete focus positions you can mimic, what I'm calling focus zones. My 720x720 guess comes from looking at sample images and what was said at the announcement ("equivalent to HD"). The math says an 11mp sensor would have 16-20 photosites per microlens, and a 16-photosite Light Field array makes sense to me.

But all that isn't overly important. The basic premise is that we're looking at relatively small final images (0.5mp) with the ability to post process focus.

Lytro is obviously shooting for the "social camera." Part of that is evidenced by the lytro.com image player and the upcoming plug-ins for other sites, including Facebook. Lytro does have the Silicon Valley thing down to a science. Their announcement had all the key media players in attendance, the product has a lean, "think different" design, and all the right marketing buzzwords are in clear display.

But don't forget to check out the Terms of Use. A couple of the legal bits are potentially an issue to me (emphasis is mine):

    "Modifications, derivative works and printing for non-personal use (for example, commercial or political) require our explicit prior consent."
    "Unlisted pictures can be viewed and shared by the user who uploaded them and by others who know the link to the pictures"
    "but only by using our light field picture player or another player approved by us."
    "Display the Lytro trademark with such content."

Here's my problem: given a 1mp final image size, could I design a compact camera with virtually no controls that has some "focus magic" to it using a conventional design? Yes. So if there's a need for 1mp or smaller "social images" Lytro will end up with considerable competition. I'm actually surprised no one has gone there yet. I guess all that customer demand for more megapixels was a distraction ;~).

Lytro continues to be an interesting experiment. I'm still not convinced it's an experiment that will work the way they expect it to, especially given how hard Lytro is working to keep you in their ecosystem (you have to use their software or software approved by them). In browsing through images on their Web site, refocusing isn't exactly something I find myself wanting to do more than once (e.g., get a focus point selected), nor does the image quality strike me as special. Would I have picked the Lytro over my iPhone to take any of those photos? Likely not.

So Lytro better have something else up its sleeve. Right now, it feels gimmicky, at best.

Vidim da i on razmišlja slično. Ako je refokusiranje jedina namjena ovog light field aparata, onda ne nude ništa posebno. Još kad se uzme u obzir da se mora koristiti njihov softver, eto još jedne prepreke.
