A small laser projects a rectangle from your camera to correspond to the field of view. You don’t need to hold the camera in front of your face, just watch your subject and the laser will outline the result of the picture. Great for holding the camera at arm’s length for unique point-of-views.
Adjusting
the zoom on the camera will obviously adjust the size of the projected rectangle. Such a simple idea, very cheap technology, easy and intuitive to use. Low powered class III red lasers won’t even blind people if the “crop” lines fall in their eyes!

Gives new meaning to the term "red-eye". [+] |

In order of people who would hate this from most
to least: |
|
| |
Anyone who was driving and was distracted by a
laser in their eyes. |
|
| |
Anyone who happened to be sitting in/walking
through the background of a picture and got a
laser in their eyes. |
|
| |
Anyone who was trying to view a popular tourist
site or event. |

I wonder if the people who voted this up have every used a laser pointer in daylight... or a camera. |
|
| |
BUT it does give me an idea! |
|
| |
obviously you would use this feature with the same discretion as you would a laser pointer... dont point at security people, moving cars, at the eyes of people, etc.... |
|
| |
there are cases where the laser would be too bright/distracting (in a museum for instance) and other cases where its too dim (direct sunlight) so (just like any feature on any product) you use it when needed and when appropriate. but haters gotta hate... |

good point... just use a 200mW green laser instead ;) |
|

That was my thought as well, but that goes back to the
whole blinding issue. I've got a daylight laser on one of my
tactical rifles that might well be slightly more lethal than
the bullet. Hmm... My other gripe would [MechE]'s #5,
trying to take a good picture of something with a dozen big
rectangles being projected onto it from different angles. |
|
| |
The laser should be projected through the lens so the rectangle would grow/shrink with the zoom. |
|
| |
Also, it might be easier to simply illuminate the four corners of an imaginary rectangle (and let the user figure out the field of view) rather than project a full rectangle. |
|
| |
Actually, now that I think about it, this wouldn't work: the
laser is being projected onto a 3D surface, but the camera
is taking a 2D image. The parts of the rectangle projected
onto things in the foreground would actually appear in the
picture, while the edges of the rectangle way off in the
background would be well out of frame, potentially cutting
off something you wanted to get in the shot. |
|
| |
The 3D/2D thing mentioned above is not a problem. The 2D image is simply a projection of the 3D surface, in exactly the same way that the laser would project onto that surface. |
|
| |
Digital cameras are available with large displays which are moveable relative to the camera body, making this idea redundant. |

Sites can't get people to obey no camera/no flash
rules now (and I've accidentally had my flash on
before myself, it defaults that way), what makes you
think anyone is going to use common sense about a
laser viewfinder? |
|
| |
I was actually thinking about this as I am thinking of
picking up a GoPro Camera which has no viewfinder
or zoom. My idea was just to do the four corners of
the rectangle. |
