kevjohn_on_mm Posted March 26, 2007 Share Posted March 26, 2007 <a href="http://www.time4.com/time4/microsites/popsci/howitworks/lightfield_camera" >http://www.time4.com/time4/microsites/popsci/howitworks/lightfield_camera</a>. <br><br><i>Specs are already circulating for a 22-megapixel cellphone camera, and within a few years 300-megapixel sensors will be no problem. But lenses, ground from glass, can?t focus light sharply enough to take advantage of this windfall. In other words, at some point you simply can?t capture any more detail. Engineers at Adobe Systems, pioneers of Photoshop, see this limitation as an opportunity to rethink photography and put those megapixels to work. Their prototype ?light field? lens attaches to a normal digital camera to shoot the same image from dozens of focal points at once. Later, software combines all the images, so you can refocus your photos after they?ve been shot. A system from Stanford University researchers achieves a similar effect by placing a lens like this directly over the sensor.</i><br><br> The article is about new lens technology being developed by Adobe, but the snippet about 300-megapixel sensors is what caught my attention.<div></div> Link to comment Share on other sites More sharing options...

ellis_vener_photography Posted March 26, 2007 Share Posted March 26, 2007 it's a logical extension of their Photomerge technology in PsCs3 - -which is a huge advance over what was in PsCS2. I've been using it to stitch together up to (so far) 13 16.7mp images from a Canon 1Ds mark2 to make panoramics that are printing at 16 inches x 72 inches @ 300dpi (in other words 104megapixels) - -and these prints are downsized from the original composite.

leicaglow Posted March 26, 2007 Share Posted March 26, 2007 This is why I think full frame sensors are going to be passe. It's about the density and technology, not the size. Link to comment Share on other sites More sharing options...
marc_van_lommel Posted March 28, 2007 Share Posted March 28, 2007 Why would we want to do that? There is no replication equipment that can display this resolution, and even the human eye is limited. Do we all want to make huge print outs ...? Link to comment Share on other sites More sharing options...
radfordneal Posted March 28, 2007 Share Posted March 28, 2007 300 Megapixels is indeed more than is useful when making a single print to be viewed in the usual way, since the eye can't see that much detail. So I think the logic is that they use the 300 megapixels to record information that can be used to create various images, by changing the focus point or depth of field, for instance. Even if you only print one in the end, you get to choose after taking the image rather than having to get the focus and aperture right to start.

emre Posted March 28, 2007 Share Posted March 28, 2007 I would rather have a 300MP camera than stitch 30 10MP images. Stitching is arduous. Link to comment Share on other sites More sharing options...
bobatkins Posted March 28, 2007 Share Posted March 28, 2007 A lot of this is hype. The science and technology are fine, but the application is limited. Sure you can use 100 lenses and focus the image on a sensor array with 300 million 1 micron photosites (although it's going to be about 20m x 15mm, not exactly a small sensor). But the image from each lens won't be all that great, the lenses won't be all that fast and the application will be a bit limited. There's no way the image will approach the quality of a full frame digital image shot with a fast prime lens. Good enough for cell phones and P&S for sure, as long as the light is good and you don't need to jack up the gain on those 1 micron square pixels.

petrana_batik Posted April 3, 2007 Share Posted April 3, 2007 -- "There's no way the image will approach the quality of a full frame digital image shot with a fast prime lens." Or use a LF camera with a good scanner. Link to comment Share on other sites More sharing options...
