What is the highest rezolution images ever made in computers? I don’t mean normal consumer digital imaging products but the most advanced technology, scanner, camera or other. Just curious as to how high digital rezolution has gotten.

Since Resolution refers to a ratio (dots per distance), not an absolute size, you’ll have to be more specific.
Do you mean:
[1] Image with the largest heighth/width as measured in pixels?
or
[2] Printer with the highest density of pixels?
or
[3] Digital camera with the highest resolution CCD?
or
[4] Something else?
It’s not so much an imaging technology as an imaging technique, but it’s possible to make gigapixel images by stitching together numerous “standard” images. In this example the creator assembled 196 6-megapizel images.
Ergh… Looks like this thread may be infected with the letter z.
As far as digital cameras go, I believe the highest megapixel number at the moment is for some medium-format cameras that can be converted to digital. The much larger negative size means it’s relatively easy to increase the pixel count without actually makings things smaller. For instance, the Rollei 6000 will take this 22 megapixel back. That’ll run you about $35,000 though. Camera not included.
I don’t think there’s a limit. If you include 3D rendered images, you can have as many pixels as you want, as long as your rendering software doesn’t crash.
In movie special effects, when they talk about digital compositing and digital matte paintings, they use terms like 2K and 4K. These refer to the approximate width resolution they are using for the images.
The needs vary, depending on the use, so a relatively static image will usually be sufficient at 2K or 2048 pixels wide. But if there’s going to be some zoom, or more likely some panning, then images will range from 4K to as much as 8K.
And that’s just 2D, it doesn’t include the hundreds of potential layers, or even when, for example, they may have to pan across a landscape, then up a building to the sky, then to clouds, then down again to the ground. A huge tesselation pic for a shot like that might be 16K per side!
Resolution of an image is the number of dots in a unit length (inch, cm, whatever).
I have seen some scanners at 4800 dpi, which is very high.
This may be a little off topic, but speaking of pixels, what size do moviemakers render their frames at? It’s got to be a pretty incredible resolution, to be able to be projected on a screen 20 feet tall, and still look like a photograph!
