Comment In camera HDR technique does not replace a superio (Score 1) 88

Firstly this kind of technique can be applied in post processing with better results (not wanting to advertise but for example using photomatix ) than can be achieved in the camera. In post processing this technique can be applied equally to Canon or Nikon or Sony or Panasonic (pick your favourite manufacturer) images, and really the only reason it hasn't reached Nikon/Sony/others in camera yet is that there isn't such a big firmware modding community following with Nikon/Sony/others. So Canon certainly has that advantage (a bigger modding community) - (but then again as the meme goes; "Canon is the camera designed by engineers for engineers and Nikon the camera designed by photographers for photographers").

OK - so now try using this technique to take pictures of objects that are moving; you instantly see the benefit of a sensor with inbuilt increased dynamic range. HDR photography relies on multiple exposures being combined together. This means that they are forced to be static, either that or they suffer from side effects such as ghosting , where anything moving across the image will be present in one of the exposures - and not necessarily in the same place in the other, leading to some weird looking end results. Alignment of the image is another issue - you need the camera on a tripod to make this work really well.
So really this technique does not replace a superior

Cold weather reduces battery life significantly, both overall battery life and usage from a single charge, so these cars maybe great in the Californian climate - but here where I live in Scandinavia - they don't make much sense, probably what we need is a bit more global warming first to make them more effective...

Comment Fireworks, explosives (Score 3, Funny) 378

Back in the 70s my father traveled from Aberdeen to London. In his baggage he had several kilos of explosives for an outdoor son et lumiere production he was the technical theater manager for. He was stopped by the security guard before boarding the plane. The guard asked "Sir what do you have in these bags" my father replied "explosives", the guard then replied "very funny sir" and waved him onto the plane. Times have changed... but it might surprise you what people think they can carry onto a plane.
