One of the things I love the most about DIY projects is that they can give a new life to the items that are destroyed beyond salvation. In this video, Matthew Perks of DIY Perks will show you how to repurpose a broken LCD TV or monitor and turn it into an amazing LED light panel. It almost perfectly simulates daylight, and it’s useful for photographers as well as filmmakers.
Modern display technology is pretty amazing. It’s come such a long way since its early days of black & white. And since shifting from the Cathode Ray Tube (CRT) TVs of the 90s to flat panel Plasma, LCD and OLED technology, they’ve come even further. But how do they actually draw that image on the screen and make it look like things are moving across the screen?
Obviously, pixels themselves do not move. It’s all an illusion. Still images played back rapidly, and our brain’s persistence of vision takes care of the rest. But you don’t really see exactly what’s going on until it’s filmed at over 380,000 frames per second and slowed down. Which is exactly what Gavin and Dan at the Slow Mo Guys have done.
People have been begging Canon for years to put flippy out (or up) articulated LCDs on their higher end bodies for years. Now it looks like they may have listened. This patent from Canon Japan shows a new rear screen design that looks quite intriguing. As well as the size of the screen, it also shows new mechanisms to attach it to different types of camera body.
One thing strikes me as a little odd, though. The dial normally found on the back of a Canon DSLR sits underneath the LCD. So, it looks like it forces people to flip their LCD out if they wanted to actually use the camera. Still, it’s an interesting concept.
It’s been rumoured for while now that Canon would start introducing LCDs into their lenses. Last week, we even saw some suggestions as to what they might display, thanks to a couple of newly released patents. Well, now, all the guesswork is over. Canon have officially announced the EF 70-300mm f/4.5-5.6 IS II USM lens.
Like its predecessor, it is a full frame autofocus lens with image stabilisation. The lens is slightly larger than the one it replaces. It weights a little more and the filter thread size has been increased. So has the diaphragm blade count, creeping up from 8 to 9, which may provide slightly more circular “bokeh”. Then there’s the obvious change. It has an LCD screen.
Canon’s EF 70-300mm f/4-5.6 IS II announcement is expected to happen quite soon. Rumour has it that this lens will be the first to feature its own built in LCD display. Up until now, nobody’s really known what for. Digicame-info, however, seem to have stumbled across a couple of patents which show what information may appear on the LCD.
Set to replace the Canon EF 70-300mm f/4-5.6 IS USM released in 2005, the new lens should carry all the usual updates we see with new lens announcements. Things like new coatings more resistant to dust and flaring, A little extra latitude with the image stabilisation. The LCD display, though, is something completely new.
If you’ve been waiting to see what Leica has up its sleeve, the wait is over. New images and details have leaked showing off the yet-to-be-announced Leica M-D Typ 262, a digital rangefinder that lacks an LCD display on the rear of the camera.[Read More…]
