Digital cameras were one of the hot gifts these holidays — the first one for some people, an upgrade for others. A blogger I know wholesale digital cameras shot a picture in an office building.which started a little brouhaha: He didn't have permission from the building's landlord, That is why this important model is often showcased at the biggest photo industry events. Several weeks ago in late March, with no big event or photo show, Canon announced their replacement to the best-selling XSi. Cell-phone cameras are everywhere too, and sites like Flickr and Buzznet — not to mention  One of the tenants had boxes of medical records sitting around in an unlocked office, visible from the hall. He published a picture of the boxes, photoblogs — make it easy for anyone to share the zillions of photos they're taking.The relative lack of fanfare made many wonder if the new Canon T1i (500D in Europe) was just a lukewarm makeover, but in fact it may be one of the most significant entry mainstream Canons in a very long time.someone said, so digital camcorders  wasn't allowed to take or publish the photos.What I discovered is that a lot of people have ideas — often very clear ones — of what is legal and what isn't, based on anything from common sense to wishful thinking to "I always heard…"That turns out not to be the case. The Canon “mainstream” model, currently the Rebel XSi in the USA, is an extremely important camera in the DSLR world. As the world’s most popular DSLR brand, the top-selling Canon is important both to Canon sales, and to the influences it exerts on other manufacturer’s product lines. Outside the new model telescopes looks a lot like the current XSi, and it can even use the same BP5 battery grip, but looks can be deciving. Inside the sensor is boosted to 15.1 megapixels, which puts it in the same league as the recent Canon 50D “prosumer” model. The T1i will also be the highest resolution entry model from any camera manufacturer.  With all these wholesale electronics  cameras snapping around us, I started to wonder about the laws regarding using them. Where can you shoot? What can you shoot?Up to this time 14-bit-bit processing has only been featured on a few prosumer models and the PRO segment.With high ISO performance a holy grail in today’s camera market the T1i features a standard ISO range to ISO 6400. That range can be expanded in 2 steps with the H1 option to ISO 6400 and H2 to ISO 12800. This  the digital still camera ISO range of the new 50D and is within one stop of the 25600 highest ISO featured on the new full-frame 5D mark II. This represents a real surprise in the entry segment, and is a 3-stop improvement over the ISO 100-1600 range of the current XSi. The AUTO shooting range is also increased to 100-1600 from the very limited 100-400 range of the XSi.Canon also boosts the in-camera image processor to the Digic 4 – which is the same processor used in the 50D and the Canon 5D Mark II full-frame. In a surprise for an entry level model, Canon also brings 14-bit analog to digital camera accessories processing to the T1i.
