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.

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.

tom60634: DxO at its inception made no claim to support anything but "Professional" camera and lens combinations i.e Canon,Nikon etc,etc.. In the case of Panasonic I believe their camera/lens corrections are built into the product. Some of the other cameras are nowhere near to be considered a "professional" rig.

The real problem can be addressed by the camera manufacturers themselves. They only need to subscribe to standard DNG format as their RAW format and most of the delays encountered while formats are being updated in various image processing programs would disappear. Pentax should be congratulated for offering both PEF and standard DNG as raw formats.

Slightly off topic, but I've often wondered why high end cameras that offer the option of in-camera correction don't offer TIFF as an alternative to JPEG. Alternatively, if they are going to use a new custom RAW, why not offer the in-camera corrections as settings data attached to the RAW. Some of these cameras understand their own sensors better than the manufactures software does but that's all lost when passing through DNG or watered down with JPEG.

Stephen123: I resent paying for a moving mirror I don't want or need in a digital system. I also resent paying for image stabilization in each lens. I resent paying for a touch screen which is basically useless. I care a lot about size and weight, but when the camera is smaller than the lens and too small for a hot shoe, that's too small. I don't need a better sensor than the one in the NEX 7. So I guess I'm done with FF. But right now there isn't a camera that I would choose if I had my druthers.

Jmmg: I am talking about the current crop of Mirrorless cameras in relationship to DSLRs and why I don't want a DSLR but am not yet satisfied with the available Mirrorless cameras.

People keep talking about a 2 year time table. But that's not what the chart shows. It shows 4 new lenses any day now, and 4 more in about a year.
