i heard a rumor that there is a "hack" that will let you use the lcd to compose the shot. i was wondering if there is any truth to it.
 
For anything like this to work, you'd need to have the mirror locked up... that way the light would be striking the foveon chip... why would you want/need to, anyway?

The best way to do that would be perhaps to shoot low-res as a polaroid equivalent on a medium> large format camera, and then adjust composition based on that?

Dunno if I would want to waste my SLR's SLR-ness? hehe

You want a hack? I'll give you a hack...

1. Put the camera on a tripod.
2. Set res to Lo.
3. Take a picture.
4. Look at the LCD.
5. If not just right, change the aim & go to 3.
6. Else set res to Hi.
7. Take composed picture.

(Lo res lets you proceed more rapidly around this "viewfinder" loop).

Get some pliers ready.

1. Get rid of the mirror
2. Get rid of the shutter
3. hack firmware :)
4. overclock the CPU for live preview
4.1 watercooling might be a good idea
4.2 build small nuclear battery for powersupply

After doing this have fun with unsharp, low dynamic range, not bright and slow (

argh...

1. Get rid of the mirror
Done. The SD9 and SD10 have an excellent mirror lockup mode.
2. Get rid of the shutter
Done. It can be cocked in opened and closed at whim, cocked in 300ms. Or we could skip cocking the shutter, if you don't mind a "rolling shutter" type electronic shutter. With the SD9 and 10, this is something you'd probably only want to do at shutter speeds 1/2 second and below (because I don't think you can roll it faster than 1/4 second at full resolution).
3. hack firmware :)
There are people working at that.
4. overclock the CPU for live preview
Unnecessary. The existing CPU is quite capable of 6mp/sec (3.2mp * 1.9 frames/sec). The X3 has pixel binning, and can output lower resolutions at high rates. The LCD is 130,000 pixels, which is 45 frames/sec.

Or even the bright 45 fps preview. ;)

Wouldn't that be great to have availiable while the mirror was locked up, say on a long telephoto, a telescope, a microscope, or a sensitive macro setup.

Or get a quick black and white preview. Or a preview with blinking overload areas. Or a live histogram. You have no idea how useful live histograms are in technical photography.

You can really spoil all the fun in here :)

Of course I know that MLU and shutter are not a problem but power consumption will be one, I have very little doubt about that.
3. hack firmware :)
There are people working at that.
Just the question if they will figure it out and ever publish something.
4. overclock the CPU for live preview
Unnecessary. The existing CPU is quite capable of 6mp/sec (3.2mp *
1.9 frames/sec).
The X3 has pixel binning, and can output lower
resolutions at high rates. The LCD is 130,000 pixels, which is 45
frames/sec.
That is the big question. Can it do live color correction in that speed?

Considering that it needs about 1-2 seconds to get the small preview of the 3.2mp done.

For Macro it would be cool.
Or get a quick black and white preview.
Now that would be really cool..

Does a composition hack need color correction?
Huh? Do I want to do composition with the colors I saw in unprocessed files? No...

Also what about the power consumption ... Ever checked how much SD9/10 consume when the mirror is up? 1 A and add the display to this (300mA) this will be the death sentence for NiMH ;>

Well, a simpel 3x3 matrix multiplication can get the colors to at least "viewfinder" quality.

That's still over 90 minutes with a good set of 2200mAh NiMH batteries.

Seriously, if we're looking at the EVF as a way of getting us through those "mirror lockup" times on the macro stand or on a long lens, well, the mirror's up anyway, so we're already bleeding a ton of power.

Although I can't figure out why. Most cameras these days have bistable mechanisms. They need to kick a solenoid to start an action, raise or lower the mirror, open or close the shutter. Once you're in a paricular state, you should be able to stay there forever, without drawing additional power.

That would be cool, along with some simple sharpening it could be usable, some more ideas:

zooming a center spot for focusing
use this thing for metering... (about the same as you live histogram).

Yes, they should hold it up there mechanically..
