On Canon EOS 5D Mark III preview (922 comments in total)

I'm using 5D II, and I don't see 5D III as the replacent of the II.
So I think, maybe this is something wrong in strategy from Canon?

trungthu: As I see in the second photo in
http://www.dpreview.com/reviews/lytro/3
When I click to the glass, the leg behind it also be in-focus, and when I click to the guitarist, the leg behind the glass turn out-of focus.
I think, this is only a software game, by separating each plan by software to put it to in or out of focus with some faults. It's only a game, not technology, as they say.
I think so. I hope I'm wrong.

Thanks HowaboutRAW.
I think I know less than you, but please explain the phenomenon that I have seen in the photo in the link I have talk to?

On Canon announces EOS 5D Mark III 22MP full-frame DSLR article (501 comments in total)

I think, maybe this is a wrong strategy of Canon as Nikon.
- The resolution has "no change", while "double" in D800.
- Full HD is like the older version (Mark II), like in D800.
Why don't they choose Nikon D800?
Not "new version" from 5DII.

tkbslc: right now this is mainly a toy, but who knows where it will be in 10-15 years. I remember back in 1999, the $1000 1.3MP digital cameras really weren't useful for anything but happy snaps, but now look at them. If you could do this on a large sensor and shoot f2.8 from infinity to mfd and adjust the best DOF and focus like we do any of the standard RAW settings now.

In October, 2002, I have used Fuji FinePix S2Pro (6,1Mp - $2450), it's not a toy.

Thank. But if you see in the photo?
Because they use a very small sensor, so all of the field be in focus, after that, they use a software to separate each plan (by use the interpolation), but with something with "opacity", the software can not distinguish it.
I hope they can do more than that.
Thanks.

On Depth of Field in Macro Photography article (159 comments in total)

""" Depth of field is dependent upon three factors: aperture value, focal length and subject distance. """
I think, there's one more factor relates to the DOF, that's the sensor's dimension. The more of the sensor's dimension, the less of the depth of field.
Because the "normal lens" is equal to the diagonal of the image sensor, and the smaller of the sonsor, the shorter of the focal, and so the wider of the DOF.

On 'No Future in Photojournalism' Interview: Dan Chung article (278 comments in total)
In reply to:

DaveMarx: First, it's all "electronic photography." One imaging sensor, one CPU. Motion, stills, audio, text, time and position data in a small, hand-held device. One investment in lenses, a common memory storage device. Stills darkroom plus audio/video post in another compact and portable device. We can document the world with one little bag of gear.

Ignore this convergence if you will, but if you do, you're restricting your creativity, and the ability to use the right tool for the job - motion when it's called for, stills when that's called for, and often both, because there are several ways to tell the same story.

I started shooting stills over 40 years ago. Within a few years I was working in radio, television, and film, eventually online and web, print publishing... It's not hard, it's all about communicating. Each medium has its strengths and weaknesses. If you can be eloquent in one, you can be eloquent in several. It's not one vs. the other, it's all for one and one for all.

"" because there are several ways to tell the same story. ""
I like it.
""" Each medium has its strengths and weaknesses. """
I agree with you.

I think Mr Dan Chung is right.
When in our hand, the camera with both posibilities: still and movie.
And we can do both without having to change the camera or the lenses.
The main ideas are "what we think" and "what we do to take it".
Thanks for sharing. Very impressive.
