In Focus... Digital Posters 5ft LCD Posters were tested at a Tokya Train Station. Data is transmitted wirelessly to these posters. How will this effect conventional printing? In this case digital might beat print (unlike books and magazines)- since readers are not expected to carry these posters and there is no need to flip pages. Just that the resolution of these posters is far from print, as yet. Kodak's Wifi Picture Frames now the world can come to your bedside. There should be a lot of scope in the travel industry for such a presentation medium... 50 Terabyte Flash Disk? made from bug protein in 2 years?! The article alerts the users that storing massive amount of data- remember it is Terabytes not Gb- could lead to security issues. No problems with that, I want one of these. I will be able to get hundreds of my DVDs backed up onto one of this- since we write on encrypted DMG partions (on a Mac), and we do not memorize any passwords either- but have a separate program to generate a different password for each DVD... By the way, this will hold over 20,000 DVDs worth of data with some space to spare! |

Digital Photography or Film Based? It will not matter, eventually. After all, photography is a process of human eye and a camera-lens working together at the right moment. As long as lenses function the way they have always been- optically and aperture-wise- photography as an Art will retain its identity. The question of the extent a digital photo will be manipulated beyond conventional darkroom adjustments, and yet be called a photo which represents that given moment- will be debated, as has been so far, even when film was scanned and then manipulated. But the big question is how digital imaging will incorporate a Zone System. Will we keep talking in f-stops or will it be arbitrary image manipulation with Curves and silly +/- Brightness-Contrast Controls on display devices. Will the exposure-feel of your image look same across display screens, even if color my not be exact? Some of my thesis (at Iowa State) addresses this issue, and was published at an SPIE conference.

Digital Photography- major issues Latitude more important than Pixel Resolution! The marketing of digital cameras solely around mega-pixels is silly indeed. As with film scanners, the importance should be on latitude of capture as well. Cheap desktop scanners have been around since the early '90s which were comparable in DPI to many high end Scitex Flatbeds or Drums. But the latitude was never the same and neither did pixels show up consistently across a grid. In film based photography, overexposing Tri-X and then under-developing it gave a brilliant range. In digital, some muti-exposure tricks etc., can achieve deeper latitude... but this is still a potent issue in digital photography Polarizers and graduated filters are here to stay! With basic color adjustments possible in digital image editing programs, those filters which change exposure relatively across a frame/subject, cannot be done away with, as detail lost in certain regions cannot be got back. |

Behind the scenes... Currently working on video presentations for our travel projects. Videos can include hi resolution photos which can be zoomed/pan in and across to present photos with the feel of video. Of course, this cannot replace the visual or audio data captured of live subjects like waterfalls. But still a photographers way to the video world. Keynote on the Mac outputs in many formats- PDF and Quicktime, are especially strong. Soon becoming a standard way in which we work once on a presentation but render in different ways. My Audio based Metering Patent has so far fallen on deaf ears- as a lot of manufactures are blind to Ansel Adams and the Zone System! It will work with digital cameras even though you can see a live thumbnail, which you could not in film. Yet detail needs to be ensured in the high resolution image... If you cannot see it, hear it! |
