When 38 Megapixles aren't enough

I've just seen an article on Hasselblad's new SLR camera with 39 million pixles. I would be quite intested but the price at $32,000+ seem a little steep.

Its not a single shot, but if you not picky you can get Gigapixel camera ;)

Are Gigapxl cameras available commercially?
Are instructions available for building a Gigapxl camera?

At this point in time, there are no plans to manufacture Gigapxl cameras for sale, nor are there any plans to release information that would allow Gigapxl cameras to be made by others. In the event that this policy changes, information will be available on this web site.

Or not :(
 
What dimensions would that be? It's so tempting to download but i can imagine having problems opening it. i'm downloading the large file (38mb) and i have my doubts if theres a point in it being that big anyway.

If you were to open a 400mb tiff in PS it would need about 1.2gb of RAM. I'm downloading it now so I'll give you the exact measurement in about an hour.

As for the camera its a medium format back. Leaf came out with a 33mp one a few months back so this isn't that exciting.
 
I just opened the 38mb one, that was 18,000 x 18,000, used around 110mb of ram, and was a bit jerky moving round and took a while loading. Which confirms my suspicions that the 400mb one will be useless to me.

I wonder how long it will be until 30mp + are common for point and shoot cameras.

Point & Shoot cameras will never come with 30mp. The biggest advances over the next decade+ will be in dynamic range, ISO noise and picture quality.

It's pointless fitting a P&S camera with 30mp when the users won't ever print higher than 10"x8".

Whilst it might be pointless, i wouldn't be supprised if they do, people are always going to want to buy the best quality camera in the price range, and although i agree with what you said, quite a few people seem to believe that higher resolution = better picture quality.

You could be right, but advertisers are always going on about the new Xmp camera, rather than the camera thats suitable for most home users needs.

It may be (in most cases would be) pointless, but if it sells...

10" x 8" x 4800dpi x 2400dpi = 1 Giga-pixel (nearly)

that's a 10 x 8 print @ inkjet printer resolution, but only 1 bit (ink or no-ink) colour depth.

Which is a pointless calc as we dont print anything higher than 300dpi in normal use, and photo print uses 300dpi or 240dpi depending on the size...
 
The Hasselblad's H2D-39 camera i mentioned is meant to have double the normal 35mm size sensor (36.7 x 49.0 mm), so it look like the death or medium format camera may have started.

The printers print at 1200/2400/4800 (or more) dpi, but with only 1 bit colour resolution ie one or no drop of ink (I know there are some printers that can vary the amount of ink ejected). At the resolution used for photo printing (300/240 dpi) shades of colours are acheived by dithering eg 100 drops of ink make a stronger colour than 10 drops of ink.

My calculation was to illustarte that it could be possible to have a giga-pixel resolution image. Also such a sensor could be be produced without the disadvantages RGBG @ 2x2 to RGB @ 1x3 to CMYK dithering conversion. A manufacturer could produce a sensor that capture a gigapixel of CMYK @ 1bit and match that directly to printer output. However at current levels of technology such a sensor would be so noisy or so large it would be impractical for typical use.

This is only any use on home printers, of which even a 2400 dpi print isnt upto a standard 300dpi wet chemital print from a fuji frontier machine or similar so i stand by my pint, 2400dpi or whatever is totally useless.
