On Kodak Pixpro S-1 First Impressions Review preview (173 comments in total)

LarryLatchkey: The first sentence represents quite an America-centric perspective ;)

"Arguably"

Ignat Solovey: These images should have been seriously edited in terms of constrast and saturation, not to mention downscaling with sharpening applied. Age-old uncoated Tessar just hasn't enough contrast and linear resolution to produce such images on modern small sensor... although the lens here works with very central part of it, and given the sample is good, that seems more or less possible, when it comes to sharpness (precise focusing is not the issue here, I guess). ILC is yet the only way to squeeze absolutely anything from any kind of lens. I think that some time I'll do something like this with EOS 5D Mk3 and Speed Graphic :) Although I was not even slightly impressed when I tried to do something similar. Recent (5-6 years) achievements in lens building render contraptions like this perfectly impractical, except very special occasions when you need non-telephoto lens with telephoto FOV, but I can hardly imagine such case.

You could have fooled me if you said they were obtained with a D800 and a micro-nikkor.,.

Tidewater: Go to Google earth then to streetview. There are miles of empty parking lots in the northeast side of the river. The downtown and suburbs look fine. These shots do not convey much of anything but I suppose the book does.
Kodak had nearly 100 years with one basic product. They were the largest manufacturing company in the fortune 500 that did not make cars or oil.

At one time, they were also the largest chemical company, as well.

...and to think they INVENTED digital photography. A Vision, missed by top management.

War is hell...even worse since we now have weapons so devastating that you cannot stand back far enough from them to avoid effects on the user!

On National Park Service bans drones in Yosemite article (170 comments in total)

I doubt they would be allowed in National Wilderness Areas either, given that their definition is:

"an area where the earth and community of life are untrammeled by man, where man himself is a visitor who does not remain, and, an area of undeveloped Federal land retaining its primeval character and influence, without permanent improvements or human habitation, which is protected and managed so as to preserve its natural conditions".

On Lytro announces Illum light field camera article (346 comments in total)
In reply to:

Joshua Zakary: Can someone explain to me this whole Megaray thing? This article says that 40 million Megarays = 5 Megapixels. I must be missing something here. $1600 for a 5 megapixel camera?

I know there is a lot of new technology which is amazing, but is the image resolution large enough for professional photography applications??

Thanks!

Lets just say it has 5 million microlenses on the sensor, and there are 8 sub-pixels behind each microlens. Each subpixel "records" light coming in at different angles through the microlens. Thus 8 x 5 million = 40 million "rays."

While not quite exact, that's probably near true...

The small effective interocular distance obtainable for stereophotography with this technique limits the apparent depth to very close objects (say a foot from the cam). Once you have objects of interest say 6feet away, the depth efect is quite small.

This is useful for macro stereo photos, but is a hinderance for a lot of other scenes.

Also, there seems to be a softness to these photos, as if they were taken with a pinhole instead of a lens.

And how much do you have to change the geometry to prevent violating a screw-top patent?

On Lytro adds 3D viewing capability to its photos article (46 comments in total)

"This is the first camera that allows photographers to create a 3D image with a single exposure at the push of a button."

Huh? Stereo cameras were in heavy use during the Civil War.

Ever hear of the Fuji W1, W3, or Stereo Realist?

Perhaps better to say with one lens...Oh, wait, that been done before, too...

In reply to:

Press Correspondent: This is a fake record. I don't know what "antique cameras" this guy owns, pinhole, Polaroids, digicams, or smartphones, or may be he owns a thousand copies of the same model, but in my book "antique camera" stands for film. The world record for having the largest number of film cameras belongs to Richard LaRiviere (USA) who owns 894 DIFFERENT film cameras that he has collected since 1960.

"Video film"?
