froknowsphoto.com This video is an introduction to using Nikon’s built-in CLS (creative lighting system) to wirelessly trigger off-camera flashes. Many Nikon DSLR’s have the capability to wirelessly command and control off-camera flashes. This system is very powerful in that you can use both TTL and manual control and somewhat limited because infared is line-of-sight and has a limited range. The amazing thing about this is that you can control the power output of several flashes in different groups directly by using the built-on, pop-up flash from your camera. In this video, I use a Nikon D700’s built-on pop-up flash to control an off-camera Nikon SB800 flash thru a small softbox and another SB800 thru a shoot-thru umbrella. By going into the flash control settings on the camera and setting the camera’s built-on flash to act as a commander, you can wirelessly control off-camera flashes directly from your camera. I touch understanding a bit about different lighting zones – Ambient light, Key Light and Fill Light. All important to understanding how to dial-in the right amount of light for flash photography.

You can view this demo of living pictures in 3D using colored (anaglyph) glasses, a 3D display, or by doing fancy tricks with your eyes. We’ve shared this video so that anyone, with or without a 3D monitor, can view the demo. Lytro’s Light Field camera www.lytro.com automatically captures pictures that can be viewed in 3D. For best results, we recommend viewing the video at 720p or higher. Want to see it without hearing it? Here’s a version for you to enjoy www.youtube.com All living pictures © Lytro, Inc, and photographers Eric Cheng, Richard Koci Hernandez, Jason Bradley, and Michael Soo.

Photographer Andy Katz joins us today on the Marc Silber show to share advice on achieving great natural lighting and composition for photographs. He does not confine himself to only one type of photography—although he mainly shoots landscapes, he also enjoys working with people, especially when he’s able to shoot record album cover photographs. Andy enjoys working outdoors to use the light of the sun, rather than staying in a studio with lighting equipment. He refers to the three elements present in any great photograph: content, composition and light. Any photo must have all three of these to successfully draw a viewer into the image. He loves taking photos when the sun is close to the horizon, since it produces a rich, golden light and creates gorgeous shadows. He is adamant about shooting photos only when the light is ideal and will often wait until the sun hits the right angle for that perfect shot. As a seasoned photographer, Andy understands how crucial it is to have reliable equipment with him at all times. When working with natural light, he needs to capture as many photographs as he can in a limited amount of time. With SanDisk large-capacity memory cards, photographers never have to worry about missing that perfect photograph.
We just published a review of Panasonic’s flagship super-zoom camera, the Lumix DMC-FZ200. The FZ200 goes back to its roots, offering a constant-aperture zoom range, like the FZs of old, but in most other respects it’s similar to its well-regarded predecessor the FZ150. Features include a 12MP MOS sensor with a maximum ISO sensitivity of 6400, Raw shooting, and automatic panorama and HDR modes. We collaborated with Jeff Keller of the Digital Camera Resource Page to bring you this review of the FZ200 – click through to find out what we thought.

A test of perceived resolution between the Canon 60d and Panasonic GH2. This is a non scientific test using gear in my own kit. I wish I could of used the same lens across the board, but the funds were not available to rent a common lens + adapters.

External video recorders are about more than improved image quality. Find out more in my review of the least expensive model that includes a monitor, the Atomos Ninja 2.
Sean Reid, at ReidReviews, does some of the most in-depth camera reviews of anyone online or in print. He has just published his look at the remarkable Sigma DP2 Merrill, which I raved about here a couple of months ago. If you’re considering one of these Sean’s review is compulsary reading.

"Every time I go back to a module I had already seen, I learn additional things. I have never seen tutorials that have the excellent mix of what the features are,
how to use them, enough of the under-the-hood information
and concepts so that I can utilize the features creatively and efficiently,
and just enough humor to keep the motivation level high. Wow!"

This is our interactive visual art installtion called NUCLEON at Boom Festival 2010. Created by the Retinafunk visual and 3D artist Hannes Neumann a.k.a. Humanspacecraft with tools such as 3DS MAX and Quest3D with some additional Help by Retinafunks Andy Weisner on building up abnd interfaxce .
Its a immersive panoramic 3D virtual reality space, and its interactive, so the the public can navigate and trigger layers and textures. in the virtual 3D space with a MIDI controller or multi touch interface. Its aim is to provide a interactive virtual psychedelic experience.
