On Lytro software update introduces Focus Spread feature article (104 comments in total)
In reply to:

Raist3d: No offense but it looks pretty bad (the effect) as they show it. Looks almost like a bad photoshop filter.

What I meant is- that I would expect them to show case their new effect well. What I am seeing looks like the results of a bad photoshop filter, at least within a wide range of settings.

That said, I can't fault you for playing with the software. I am only saying given they are going to try to present a good foot forward, I am not too inclined to put time into it, unless they really screwed up their marketing and what you can do yourself with their own tech is really notably better.

Well I am going by what Lytro is showing. I mean, it's the same company that makes the technology, and they made a video marketing it, I am not expecting it to change then.

NetMage: These are the kind of features I expected to see. Imagine being able to output video where focus moves smoothly from subject to subject - a lot of work now, but it could be automated.

Video resolution does not need to be very high? We are already running at 1080p and about to enter 4K.

In reply to:

LaFonte: It is obvious what they are doing, isn't it? Basically trying to sell customers an inadequate proof of concept with hopes that someone big will buy them off. As we had seen wit foevon, this "catching up" can go on for perpetuity. The underlying tech is interesting, but at the end professionals still use tried and true and amateurs loose patience faster than you can say rip off.

Meuh- if you add the Foveon ISO and color constancy issues, I don't think it's as good as you say. I wish it could have kept up the same way like the previous to Merrill sensor in those areas.
And the Quattro has its own issues.

Everlast66: The biggest Lytro problem is that they are trying to solve a problem that does not exist!

A lot of the fun when taking photos is to decide what do you want in focus and how much separation (or no separation at all). It would be much less exciting to just snap photos around and then spend most time on the computer fiddling with sliders.

If it was giving you quality (resolution, DR and ISO) comparable to APSC or FF cameras and in addition give you some limited focus adjustment to correct slight back/front focus issues it would have much more success.

Not buying the luddite argument here Rishi. You should ask of those top wedding photographers how many would love to play in post with the focus. Better yet- ask a reasonably good but not in that circle you mentioned wedding photographer if he can afford the extra post time.

Also if you mention the Nikon D750 gets around the issue you mentioned above, wouldn't that be a better solution than this then?

Henrik Herranen: Look at the transition zones between the hands and the background trees in the "Shallow depth-of-focus" shot. Even at this small size, they look pixelated and quite fake.

I am still sceptical.

@Rishi- that's what I meant when I asked above on "does it scale?" As he mentioned it's not trivial. There are several technologies out there that hit a wall once you need to scale up. This could be one of them. But at least for web/monitor delivery it could work.

As for editing depth maps- AFAIK this has been done already in other fields (video games), so yes, no reason why it couldn't be done here. More work in the computer, less work in photography though.

A bigger question is does this scale up? We can talk all we want of this and that technology and how many times "it was said this and that" but that doesn't automatically proves the technology successful.

Barney- you are counting the hits :-)

Fuji SR was pretty interesting except that it didn't scale up in resolution. Scaling up a light field sensor has so many compromises. I guess if it reaches delivery of monitors it works though.

Well Roland, maybe some people don't find it ugly, particularly those who see it in person. Ergonomics trump usability in my book. Check what Michael Reichman from Lula has to say about it.

In reply to:

draschan: the test images do no justice to this truly amazing camera. the pentax 645d has alreadybeen an amazing machine. it is a wonderful tool when not abused to make random snapshots without focus, composition, subject etc. everyone who knows what MF can do would be glad to have this camera. it is a huge step forward to have such quality (in the hands of capable photographers) available for such a low price. if I'd have the money I'd get it immediately.

@iAPX, @Samuel- what iAPX just mentioned reminds me when I fist went from the Olympus 4/3rds original system w/Zooms into a Pentax K-5 with primes. It took me about 7-9 months to get the K-5 at an intuitive level with those primes. It wasn't the camera. It just goes to show just how used I got to the idea of using zoom lenses with a 4/3rds system and what skills you have within what constraints. I feel I am now more aware of focal lengths, etc. since using primes forced me to see things very differently. I even see how I use zooms differently. In either case neither tool was the one who "made me a better photographer" or my skills automatically increased by virtue of just buying the camera. I had to work with it.

In reply to:

nunatak: leica has no choice but to fix their jewelry. they can't afford to have the next generation perceive them as tarnished. JMO.

Why would they perceived as tarnished with this awesome honest forthcoming customer support? You know who could learn here from them? Nikon. Remember all those Nikon D600 issues? Or how about "don't care" attitude that seems to exude on their Nikon 1 system?

In reply to:

turvyT: The first guy sounds like someone who knows what he's talking about --regardless you agree or not. The second guy sounds like someone has never used a MF format before. What's the point of such a piece of test? Trying to deter a John Doe from getting the 645? There is no need for that. Every camera does its natural selection by itself.

The point is that even walking with that expectation (for any camera) seems to me like misplaced hopes and faith. It's not just the 645z, and it drove the point home only by banging your head against the wall if you will. Why was that approach taken to begin with is, why even think the camera would do the photos for you, and why not think the same about any camera is the point. Probably why those expectations where at the beginning- thinking this only applies to the 645z.

In reply to:

Cooleator: I can see the logical differences compared to lower mp FF, however I'm pretty sure a 30mp+ FF Foveon sensor would trounce this 50mp MF sensor at low ISO...

I wouldn't make the claim it would trounce it even at low ISO. Not even Sigma claims equivalence to a 50MP Bayer sensor, let alone one without an AA filter.

Even at lowest ISO depending on subject, Foveon has color constancy issues (Merrill and Quattro).

Samuel- I think the main point to me is that what you said on the camera, can be said bout any camera. If you shoot better photographs with a smaller camera is because you are used to that tool. But not camera takes "good photographs"- that's the photographer. From iPhone to Large View Film.

A lot of what you wrote seemed like you were expecting a good photo as you said- by the camera itself. So it's not just knowing the 645Z as a tool, but that the expectation of any camera taking a good photograph for you is already on the side of a misconception.

Said with respect and as someone who fell in that trap in the past.

In reply to:

hooverfocus: Basically, second writer, who's usually an average Ford Focus driver, decides to take a Ram for a ride into granmas' tiny European village. Just for fun, y'know. Nothing wrong with that, I guess, except he also expects the whole driving experience to work out just fine. Then, since it doesn't, he feels compelled to note that, in fact, this 300hp pickup truck isn't performing like that other 300hp sports car he once tried. Oh, but the truck was still pretty cool, y'know, even though—he concludes—you should learn how to drive it, in order to, well, drive it. Too bad 90% of the article goes on about how he's not getting what he want out of the thing because he doesn't know how to use it or what it's made for.

Sorry, but no.

I hate to say it but that's a great analogy. I would also add, this is how you should treat any camera anyway- those who still think great photographs are taken by the camera are stuck in their evolution of their skills.

No offence to dpreview but he did sound as turvyT is saying (except for the very end). But I would add a bit more- Dr. Spencer - "What I found was that this incredible camera wasn’t going to produce good photography by itself. It wasn’t going to let me passively walk in to a situation hoping to make a little bit of art out of it. I couldn’t just wander about with it and let set and setting determine what picture I was taking. The 645Z doesn’t like that. No, you have to be deliberate. The photo has to be in your head as an end goal, and only at that point does the 645Z become the tool to get the job done."

That's how near every camera should be treated. Of course good photography doesn't produce by itself :-)

On Ten things you need to know about the Sony Alpha 7 II article (270 comments in total)
In reply to:

sierranvin: Why oh why does Sony so consistently fail to offer a model with all the premium features in ONE ELITE PACKAGE??? What happened to the 36MP sensor from the a7R? Why do they add these nice new features, then drop the sensor back down to 24MP??? Is the Sony corporate culture programmed to always earn a B+, never an A?

@sterra- chill out son. I am merely explaining that your extreme "team B+/A" whatever is a bit overboard. One thing is to express your desire for your needs, another to think that Sony is just incompetent because they can't satisfy your specific needs.

As for Sony losing money you need to be more careful and expand which areas they lost money. For example- maybe their cameras are successful while other divisions are dragging Sony. Did possibility remotely occur to you? Apparently not, since you know what Sony should do apparently.
