Photographer's remorse: you're looking
through the viewfinder, a candid scenario
comes and goes and you realize "that
*would have* been a great shot!" The
moment is lost - until you hit the Second
Chance button. The camera has a big (60
sec.), fast (24 fps) buffer that is always
remembering
the last minute of images it
sees; the aforementioned button freezes
the streaming and you can run it back and
pick out the best frames. I think this
would require continuous autofocus and
autoexposure and probably an assistant to
change the battery every 5 minutes. But
maybe a nice feature when the technology
is ready.

they have high res digital video camereas that you can capture stills from, so this is already available. |
|
| |
I can't see the point of the camera being
on permanent record; the chances of
the camera pointing at something
useful while on a neck strap, or ina bag
or pocket are negligable. |
|
| |
What might be useful is a video mode
that is activated when you are
composing a photograph. You not only
get to shoot video interspersed with
higher resolution stills but would get
some record of that 'moment you lost'. |
|
| |
You might be able to survive without
the lovely battery assistant, too. |
|
| |
[st3f], ok, make the streaming feature
run only while your photo is being
composed; it could trigger from the
usual halfway depressed regular shutter
button. Re: the video modes; the
difference here is that the buffer runs at
the full resolution and compression
selected for the desired photos.
[xclamp], how high is the res on these
things? |
|
| |
If you're going to have it recording from when the button is semi-depressed, why didn't you press the button rather than miss the shot? |
|
| |
It's not possible to have a camera continuously recording at the resolution of high end digital stills cameras and still be ecenomically viable (otherwise they'd be on the market.) |
|
| |
Most (if not all) shots get away because the camera wasn't pointed in the right direction or was still in the trunk of the car. If you're looking at a good shot through the viewfinder, and fail to press the button, you just need to improve your photography skills (or lose your fear of wasting film - a non sequitur in this digital age). |
|

[scooper] and [DrC], the reason I didn't
press the button, i.e. missed the shot, is
that I'm a crappy photographer. The
point of the feature is to help the rank
amatuers who don't want to invest a lot
of time in becoming serious hobbyists.
Good for kids' birthday parties and
sports meets and such. |

My Casio QV-770 had a feature that would record three pictures at 1/20sec intervals BEFORE you clicked the shutter button. Drained batteries pretty quickly, though. |
|
| |
I think that if you JUST missed the shot, it would be great. Like if you pushed the button a little too late. And I think the camera should have a setting where it starts recording when you turn it on. But it doesn't have to, you can turn it off for regular camera mode. And, of course, the recording wouldn't stay in the camera for long. A minute, maybe. Constantly deleted. Just run the thing off your own energy supply in your body, and you'll never see it die! |

[DrCurry]: A camera with a small buffer and the ability to capture the last few pictures would be useful not just for bad photographers, but also for people wanting to have photographs of an event where it's hard to time the shutter click perfectly (e.g. trying to get a pitcture of a cat pouncing, without knowing exactly when it's going to pounce). |

Your comment about the difficulty of capturing acceptable resolution at an acceptable frame rate is a good one, though I suspect that having a buffer of 4-16 pictures would be cheaper and easier than having to capture a continuous video stream. For example, it may be useful for a variety of reasons to have a camera contain a mosaic of separately controlled pixels (e.g. all pixels with even x and y coordinates are controlled together; all pixels with even x and odd y are controlled together, etc.) Elsewhere, for example, I've suggested such an arrangement as a means of trading resolution for latitude. With proper control circuitry, such an arrangement might allow a photographer to exchange a 50% reduction in resolution for a 4-picture buffer. |

We've had these for years in England. |
