Largest Digital Photograph in the World 318

Posted by CmdrTaco from the thats-a-lot-of-bits dept.
thrill12 writes "Dutch research institute TNO has unveiled what it believes is the largest digital photograph in the world. The image contains 2.5 gigapixels or 7.5 gigabyte worth of data. It is composed of 600 single images shot by a computer-controlled pan-tilt unit in 7 second intervals. Afterwards, all photos where stiched together (compare: panorama tools) using the capacity of 5 high-end pc's in about 24 hours time."

    I'd like to take this time to point out the lunacy of the 'megapixel' ratings for cameras

    A number determined from the multiplication of length and width in pixels of an image has about as much to do with the quality of a picture as the size of your passenger cabin has to do with the speed of your car. Yes, you can print larger pictures without seeing pixels if you have a higher megapixel count, but chances are it's not the resolution of your photos that you'll notice.

    A major factor in the quality of any image is the quality of the optics used to take it. That means the lens, the glass used to focus and point the image onto the sensor. Quality glass, such as low dispersion glass (I'm preferential to Canon's "L" glass) will create images with sharp edges, crisp focus, and good bokeh. Use cheap glass and you'll get the opposite. Effects like soft focus, purple halos, light leaking, and distortion will all still be present if you use poor optics, no matter what the MP rating. I wonder how many people have upgraded from a 3 mp to a 4, 6, or 8 mp camera and still found lackluster results.

    My point, a camera has many more features that determine quality than just the megapixel rating, when you choose one, consider these as well and you'll be happier. And here's a plug, dpreview.com does some awesome camera reviews (I'm in no way affiliated with them).

    • What is your point? We already knew this.
    • Not only because of its optics, but because the improvement in image quality I have with the pictures having nearly four times the resolution of my old camera.

      More pixels with bad optics might mean more pixels to render noise, but I didn't upgrade my camera because of extreme artifacting or light noise.

      I wanted more bits per flick. The benefit of buying a (just widely dropped to $199) Canon PowerShot A75 is not only the ass-kicking feature set, but because they use higher quality components - plastic, gl
    • It isn't lunacy.

      With optical cameras, the resolution and clarity of the image is more influenced by the optics (lens, etc) than the film, because the film is capable of storing an obscene resolution. A cheap little disposable camera is capable of having that same picture printed at 3"x4" or 8"x10", and the only thing that influences it is the optics that were used as to how clear that image is.

      For digital cameras, the optics are not nearly as critical in defining the quality of image as the CCD is (photor
      • Yeah, for the most part that is true, but your average cell phone camera is 640x480 - so was the mars lander (rover?) had a camera with the same resolution. Optics do make a difference, a crappy plastic lens will make a really crappy picture regardless of the ccd behind it.
      • The problem is that MP is a sham when you have CCD's that are not all built the same.

        Lots of CCD's you see right now have simple RGB filters, and adding up all those filtered pixels gives you an MP rating.

        But what happens when you have sensors like the Fuji that rotate the photosites by 45 degrees? It has a real apparent affect on resolution that is not really measured by the raw MP rating.

        Or consider the foveon sensor, a stacked array of sensors which has the pixel output of a 3.6MP array but 10.2MP wh

      Quality glass, such as low dispersion glass (I'm preferential to Canon's "L" glass) will create images with sharp edges, crisp focus, and good bokeh. Use cheap glass and you'll get the opposite.

      Bokeh comes from the number of aperture leaves and their shape(there are some non-straight-edged aperture leaves). It has -absolutely nothing to do with the quality of the glass-.

      Furthermore, Canon's $60 50mm/1.8 is plasticky, cheap, blah blah- but it's just as sharp as the faster, metal (heavier) L-series lens, and it doesn't suffer from the mild barrel distortion the L-series lens does. It has fewer aperture blades, so bokeh is not as great- which is pretty much the only reason pros buy the L version. Consumers buy it because they want a red ring around their lens and they don't want to be caught dead with a plastic lens.

      You can stare at lens charts until the cows come home and argue about image quality. The L-lenses are slightly better in most image quality categories since they do generally use the very best of Canon's technology, but their chief advantage is that they are built with stronger but heavier materials, aimed at professional users who don't mind that the body is thick metal. Phil Greenspun claims he's dropped his 70-210/2.8 IS on the floor and it worked fine. I'm not about to try with mine, but I can tell you that the thing is built like a goddamn tank, and designed to be modular for easy servicing. Even the tripod mount screw is replaceable...

      • Bokeh comes from the number of aperture leaves and their shape(there are some non-straight-edged aperture leaves). It has -absolutely nothing to do with the quality of the glass-

        Bokeh comes from a NUMBER of influencing parameters, just as the "bouquet" of a fine wine can be affected by a number of different wine-making techniques.

        You're right that the shape of the aperture has an effect. More leaves, or more rounded leaves, will smooth out the circle.

        Another factor is whether the lens uses a reflex

      • Firstly, quality of glass certainly has a bit to do with EVERY ASPECT of the image created. Use shitty glass, you'll get shitty images, it's that simple. Note that I didn't say the L glass is the only glass that produces quality image.

        Bokeh is absolutely affected by glass quality. Especially when dealing with numerous small points of light, such as cityscapes and reflections on choppy water, using low dispersion glass will create smoother but still "contrasty" bokeh.

    In a way, this is funny. The best way to handle huge images is by tiling them. I like to play around with maps and satellite images (see here with [schaik.com] and without [schaik.com] grid) and have learned the lesson that to put that type of large images on a web server, you better cut it into tiles.

    Flash based zoom/pan/tilt viewers do the same thing. A bit more advanced, but you download only the part that is currently in view. Even when you open a PDF in your browser, just the page in view is downloaded. And think about those huge video walls.

    So, the funny part is now that you take many, many pictures, then use a lot of processing to stitch the results together, and then cut it into tiles again to display the resulting image. Wouldn't it make more sense to put some more effort in that robotic camera control device and make that so accurate that it can take the pictures, still touching, but with zero overlap? That would be cool!! I suspect that making the high precision optics for such a camera would be really, really expensive. Which is probably why TNO did it the way they did.

    • As cool as it would be to create a large-format picture like this using a camera with zero overlap, it's impossible.

      Very simply: When you're putting multiple images like this together, you quickly become aware that the images you take do not form a flat surface. Because your camera is located at a single point, and is then rotated in multiple axes, a complete sweep of all pictures in all directions would form a sphere made of rectangles. Think of it like an inside-out disco ball.

Each time you scroll, you only have to download a couple new tiles.
