ianp5a: The point of the device is to encourage learning of the technology. But rather than being a stepping stone for beginners, it drops them right in at the deep end. It offers nothing new to help people learn. Apart from the price.
If you have never used a command line before and you blindly paste a command in, you have not learnt anything and you probably will not understand any error message if something goes wrong. In which case you will probably need to know a whole load of other commands to be able to cope. Which is why he pointed out this problem. Sadly, scaring potential users off. The thing is only suitable for a few.

It's not an educational product for teaching technology. It is a component for a low cost open computer hardware platform create by DIYers and often used for education.

Greg Lovern: When wonderful old works, who's current copyright holder can't be located and may not even know that they inherited the copyright, can't be published without risking multi-million dollar settlements, the culture is impoverished. That's how it is today now that the copyright law pendulum has swing far, far over to the side of protecting creators.

It's possible to provide reasonable protection to new creators without disappearing the works of wonderful old creators who's current copyright holder can't be found. But finding that balance requires that new creators be required to put some minimal effort into registering their works.

Works can be registered in aggregate, as in a large set of photographs or the entire contents of a magazine.

All creative works are automatically protected without registration in all countries that ratified the Universal Copyright Convention. That is most countries and includes the US. The US used to have registration and the argument was that it enriched the library of congress, not that it was necessary to protect artists. To preserve this goal, the US now requires registration in order to get punitive damages in a suit but not to get compensatory damages.

On Photoshop CC: Adobe responds to reaction article (1853 comments in total)

I haven't seen any speculation about whether this will also effect Photoshop Elements. Is anything known?

On Fujifilm X100S Digital Split Image focus - how it works article (101 comments in total)

I think I would prefer a combination of contrast, phase-detection and Sony's focus peaking; as long as the phase-detection is better than the current Sony on-chip system.

I'm curious to know why OpenCl is Windows only. Is the Mac OpenCl still not stable?

Gionni Dorelli: The clients who commissioned and paid the photographer to take the photo, will always have the right of framing it, hanging it on the bedroom wall and looking at it anytime they wish. Or they can put in an album and keep it on the coffee table, so they can show it to granny when she comes around.
No law will ever takes those basic rights away. Do not worry!
For all other uses, they have to pay royalties.
End of the story.

This makes the situation very, very similar to the US where professional portraits, wedding photos, etc. come either with or without complete rights, often at a different price.

The amount of hostility here toward a fundraiser for Reporters without Borders is surprising.

The price is quite favorable compared to a Leica. If they rein in the weird color schemes, I suspect it's success will depend on how if feels in the hand.

photofan1986: Sony, come on, enough cameras already! We want decent lenses, as well as some pancakes!

Sony NEX have 3 bodies (going up to 4 in September) it seems like a lot because they update each one each year. The 3 line is optimized for cost, the 7 line for image quality, and the 5 line for physical size. This does make me wonder about the role of the NEX 6 line.

Contax G lenses and adaptor are also a fine choice.

Stephen123: This is a little confusing. It has to do with putting more of the circuitry on a different layer. But also has something to do with clear sensor pixels. The point of clear pixels would be if they can be stacked on top of other pixels not circuitry. Are they really saying, a three layer stack? Clear monochrome pixel, then color filtered pixel, then circuitry? At each pixel location? If so, that's rather significant.

Thanks R Butler for making it a bit clearer.

Alan Brown: was it a Billion dollars to send this to Mars? (vaguely remember this figure in a news broadcast.. might be a whole lot more. )

Great inovations and technical skills to get it there .. no doubt abut that. But you can't walk here on Earth in the daytime and feel 100% safe.

begs the question....

Fundamental research pays off better than most other investments. This has been shown over and over. Space exploration DOES help us here on Earth. Or look at the Large Hadron Collider. Again, fundamental research. One accidental side effect? The World Wide Web.

In reply to:

Neurad1: I've owned two Canon Photoprinters in the past 8 years or so. Both have developed banding on the prints presumably due to a bad print head. In neither case could I clean the problem away using instructions suggested online. Most recently after (carefully) cleaning the head the printer would no longer recognize it. The printer was only three years old. This is apparently a very common common problem with Canon photo printers.

I will never purchase another Canon printer.

I've had good luck with the Epson R series Photo printers. They need cleaning from time to time, and the ink is expensive. But it's cheaper and more convenient than the same quality print from a lab. And the cleaning works. Just be sure to leave the printer off when not in use. Otherwise the heads clog up.

Twebain: okay fine i won't have problems with tiny buttons and unreadable UI text but browsing the web will be permanently upscaled and any other fixed pixelsize based content (like photos) will be extremely tiny, will it not?

Pixel doubling is automatic, unless the app maker turns it off. So most web graphics will be 110ppi unless you zoom in.

Neodp: That is why I would not consider that Sony camera line.

This is why I would not consider Sony, altogether, anyway. Just Google "Sony rootkit". We will never forget what Sony did.

Sony Electronics has actually been in court on the opposite side from Sony Music on issues of fair use and overzealous copyright actions.

gogo2: D800 already outdated based on pixel count. Nokia 808 already trounced D800 with 40mp sensor. I think DPReview should review Nokia 808 alongside D800 and see which one takes the cake.

Yes. The Nokia 808 can take 38mp photos. Yes it is extraordinary for a cell phone. But the sensor, lens, body, interface, stabilization, and available lenses and accessories come no where near the D800.

On Just Posted: Lytro Light Field Camera review and video article (309 comments in total)
In reply to:

Dmitri Alexander: “Light field" technology seems like a needlessly complex way to achieve the goal of selective focus after taking a shot. As the review correctly states, “in a small-sensor conventional camera, you tend to get depth-of-field that stretches from near the camera, out to infinity.” Given that, a camera maker should simply develop user-friendly, in-camera firmware that allows you to selectively defocus everything in the image except what you want to be sharp. In other words, synthetic bokeh. Could that be so hard to invent?

To do that, you need to store the depth information with the image. Otherwise you're not actually selectively defocusing, you're just selecting a region of the image and blurring it. That's just standard Photoshop. So what you're suggesting seems to be a small sensor image with the depth information stored with the image. That's exactly what the Lytro is.

In reply to:

inorogNL: can someone explain - how is it posible to put this much pixels in a (phone) sensor this of size? and why are digital camera makers not doing it also ?

The computer chip manufacturing industry has been advancing faster than the camera industry (and faster than almost everything else as well). There are going to be a lot of possibilities opening up with new sensor chips; better light sensitivity, smaller sensor sites, more randomized sub-sensors for R, G and B, and probably more companies embedding phase detection into CMOS chips.

This looks like it really is a 41MP camera to me. The pixel binning may just be a marketing decision based on file size and what consumers generally use a camera for.
