pixtorial: I prefer Pfaffenbach's photo, the composition of it is better, he (or his editor, as I'm sure it is just one frame of many) chose the better shot. The color pops a bit more (important in this context, it was Rio after all), the background gives more context while still giving that sense of speed, and Bolt is isolated more from the other runners.

I also prefer it because Bolt's face, and the face of the guy wearing #7, are in focus - makes the photo "pop" for me, more than the slightly blurred [focus and/or motion blur] of Spencer's photo.

I also wonder how people's "go to" site for photos affects the "popularity" of these images. i.e. if more people are used to searching Getty first, then that could be one reason a Reuters photo might not get picked as often.

HowaboutRAW: Um except the photographer in question has already pointed out a problem with the Swift response.

Swift's people say that the photographer keeps the copyright to the image. And that's true, but no one was claiming that Swift gets the copyrights to the images shot.

It's that Swift can use the images if she wants, and the photographer can't even if he/she still owns the copyright.

Swift would be in a better position if she'd not made that misrepresentation.

(And Swift's tour would be better served employing the photographers as well salaried staff paid in advance, even if something interrupts the tour, with the written agreement that these photographers assign the copyrights to Swift, but the photographers receive credit and an agreed up residual any and everytime one of their images is used.)

Taylor Swift and Co. can be pigs too, and lie about it, not really a surprise.

How bizarre:

Do I understand correctly that her management is saying:

"You retain the copyright to the image, and we can use the image for anything we want - as often as we want - but you can't use it more than once without our permission".

What does owning the 'copyright' on a image mean, if you have to get someone else's permission to use the image?

Adrien S: "Pricing has not been revealed."
Ok, so I guess a thousand dollars for every one million pixels is consistent with their MF lineup.
So what about $80K? That's my guess. ;)

And they are expecting it to be used in multiple-camera setups, so multiply whatever you think times 'X' number of cameras in the array.

Yikes! = I'll stick with my dSLR. :)

But does look great for the intended market.

-Forward Motion Compensation
-Direct connectivity with FMS, GPS/IMU
-Files include IMU and GPS data
-USB 3.0 connection to host computer
-Synchronized shutter release for multiple camera installation

Would love to see someone try to mount this - with the 240mm lens - on their quadcopter. :)

But seriously... it makes much more sense when they mention owners of gyro-copters or ultralights using these - since they are medium-format cameras, and not competing for the GoPro market.

GabrielZ: This is what the Surface should've have been from the beginning. A good alternative to the iPad now. Microsoft, Samsung etc..have caught up with and are in places - surpassing Apple at their own game lately.

I hope Apple can counter these recent announcements with the upcoming large screened iPad 'Pro' and iPhone 6S. Next years iPhone 7 needs to be something very special!

"Next years iPhone 'X' needs to be something very special!"

No, it doesn't.

People say this every year, and Apple still sells gazillions of whatever model they produce.

The new MacBook is a great candidate for an iPadPro - just remove the keyboard & trackpad and attach a touchscreen... and then port iOS software to Intel, and release an Apple stylus, and ...and wouldn't it be cool if it would dual-boot via Bootcamp between iOS and Win10?? :)

God, I love DPR!

"A reviewable sample arrived in our offices..." and - as I write this - the current totals are:

I own it: 16
I want it: 124
I had it: 7

Makes me want to bump the "I had it" number to 8... just "for the lulz". :)

AbrasiveReducer: Lovely. There is more specific how-to information in the first 3 paragraphs than in many long articles. And it's not obvious stuff, either. Who would have known not to use LEDs?

Overheating counter? Reminds me of Nikon SB-900 flash, which has (had?) battery overheating problems. But the Nikon could flash repeatedly when using external battery pack. Wouldn't using an ext batt help with the Canon flash? Or is that too much of an added expense?

PhilTate: I know very little about optics, but it seems that eventually the image will wind up on a flat surface, either as a print or on a computer screen. Won’t it take some doing to get the curved image flattened?

No, it won't take any doing.

A lens takes a flat image - like the ones people take of brick walls to check for distortion - and produce a curved image... which additional lens elements/groups are added to the lens to flatten the image onto the flat sensor.

And those extra elements/groups have varying amount of success at correcting for distortion - which is why software in the camera, or post-processing software like Lightroom, DxO, etc are used to help flatten the image.

Having a sensor with curvature, which matches the curvature which is unavoidably introduced by the lens, automatically corrects - or "cancels out" - the curvature and gives a flattened image with no other processing required.

The same way the curve of the retina in your eye cancels the image-curvature produced by the lens in your eye.

And - just like your eye - there is no ability to zoom in such a system.

mailman88: Ok....answer this question, is it cheaper to make of more expensive?

1. Extra steps in production = more chances to fail QA = more expensive

2. Barely past prototype stage = no economies of scale = more expensive.

3. Only usable in fixed-lens cameras = niche market = no economies of scale = more expensive.

In reply to:

Clyde Thomas: Contax and Rollie both produced exotic vacuum back cameras to keep the film perfectly flat. Precision German engineering made a really big deal about that back when.

Is Sony throwing us a curve or shooting straight here?

Shooting straight. [I see what you did there]

Film needed to be flat, because any sections of the negative flat against the backing-plate would be out-of-focus = ruining your pictures - in arbitrary ways - and you had no way of knowing until the film was developed.

At least one company is innovating in the cellphone market!

I don't see Apple or Samsung giving us the selfie panorama mode. :)

Mapel: This is very interesting... and that tree is really huge!

"Everyone wore hats and jackets..."

Reminds me of seeing a motion picture made in San Francisco in the early 1900's. Camera was mounted on one of the streetcars - on level ground, not the hills - and showed all the people on the street staring at the camera as it passed-by.

And every single one of them - man, woman, child - had a hat on.

I don't think I would have noticed if the person posting the video hadn't asked viewers to try and spot anyone without a hat on. :)

On article Blackmagic Design launches Blackmagic Studio Camera (24 comments in total)
In reply to:

InTheMist: Can someone explain to me what it is?

Its a 4k video camera attached to a LCD-screen - "viewfinder" - which is about the size of an iPad.

Since most "Pro" video rigs use a larger screen connected via cables, and supported via brackets & whatnot... these guys just decided to mount the bigger screen directly to the back of the camera.

Its called a "studio" camera, because they expect it to be tripod-mounted in a video studio... and this design eliminates the extra bric-a-brac needed to connect & support the bigger screens people would be buying separately.

It just doesn't help people who already have larger LCD-screens for use with video cameras. :)

EDIT2: a recent example of the complexity of attching/supporting bigger screens & boom microphones with smaller video cameras:

In reply to:

Peiasdf: So how much is 100 kgf consider it is not a SI unit. 100G?

I just assumed it was similar to lbf, i.e.
lbf = pounds force
lbm = pounds mass
kgf = kilograms force ???

... kg/cm2 x cm2 [camera surface-area] = kgf [total force/pressure applied to the camera]

kgf/cm2 = kg/cm2

Dimensions given as 112mm x 66mm = 11.2cm x 6.6cm = 73.9cm2

100kgf/73.9cm2 = 1.35kg/cm2

It seems like the display would have to be pretty dim, in order to be transparent enough to maintain eye-contact between photographer & subject... and pretty-much a one-trick pony if that is the only use-case such a large display is good for.

On article Miggo Strap and Grip review (86 comments in total)

Too bad the Sling has that "try to accomodate all cameras = all cameras get lousy handling" mounting-plate.

EDIT From the photo, it looks like the camera would be better-off mounted further-back on the mount - where it shows shorter-lens camera should go... but even then, the neoprene might have enough "give" to still let the camera tilt-down enough for the lens to contact the wearer's belt-buckle. END EDIT.

Grip does seem a better design, since it is not trying to fit wide range of camera sizes.
