Understanding Electricity: Nikola Tesla

Nikola Tesla In my opinion, one of the most neglected inventors of all time. The names Edison and Marconi come to mind as familiar, but Tesla? Most think of a car. Few know that Tesla is responsible for alternating current, florescent lights, radar, remote control, generators that preform efficiently, the spark plug, and many others. The U.S Supreme Court declared in 1943 that Tesla, not Marconi, was the true inventor of the radio.

News: Two Bright Nebulae in Orion's Sword

My attempt at real astrophotography. The two bright nebula are M 42 and M 43 located in Orion's Sword. I took about 20 images at ISO 800 and 1.6 second exposures using a 300 mm lens and stacked them in Photoshop after repositioning them because of the movement of the sky. This is cropped in just a tiny bit.

News: Photos of Mercury and the crescent Moon

Tonight, I saw Mercury for the first time. Mercury is a hard planet to see, even though it is quite bright, because it's orbit is so close to the sun. The angle Mercury makes with the Earth and the Sun is never more than about 25 degrees and most of the time it is much less. As a result, you can't ever see Mercury during the night but at a couple of times in it's orbit you can see it at either dawn or dusk. Right now, Mercury is close to it's greatest eastern elongation and can be seen low in...

How To: Your iPhone's Flashlight Doesn't Have to Be That Bright

Have you ever been to a hip restaurant with horrible lighting? You need your iPhone's flashlight just to read the menu. Of course, sometimes the light comes off too bright, blinding the people next to you. But don't settle for a flashlight that's too bright. You can choose from four different brightness levels instead, to perfectly fit your situation.

How To: Light Up Your Whole House with This DIY 'Nuclear Explosion' Chandelier

If you're the kind of person who misses the bright, sunny days of summer during the colder months, Michail has the perfect addition to your home. He built this "Nuclear Explosion" Chandelier that's as bright as daylight, so you can recreate the feeling of summer, no matter what time of year it is. It puts out 99,400 lumen (a typical 60W light bulb only produces 800 lm), so it takes quite a bit of electricity to run. Michail used 7 metal-halide lamps, which are much brighter and more energy ef...

Horror Photography Challenge: Guitar Ghost

I thought this one was interesting. Long exposure while zooming out. All of the bright spots from the guitar became streaking lines. Maybe not that scary but I thought it was an interesting technique with an interesting result. Probably would have worked a lot better in a better location! My classroom isn't that interesting.

How To: Do keyframing color correction in Final Cut Pro

In this episode of Final Cut Help, Richard Harrington takes a look at keyframing the three way color corrector in FCP. As details change in a movie clip you can have the filter adjust its values over time. This example uses a video of a bird starting in a bright sky and ending in water which is darker, the contrast transition is controlled by keyframing the saturation and color correction.

How To: Fix exposure in Final Cut Pro

In this Final Cut tutorial, Richard Harrington discusses the common problem of backlighting, exposure and what can happen when shooting video outdoors.

How To: Balance out exposures in images with Photoshop CS4

In this Photoshop tutorial, Richard Harrington takes a look at balancing out exposure issues inside of Photoshop CS4. Mixed lighting on a photo can cause portions of the image to be too bright or too dark, fortunately Photoshop gives us some great tools to take care of these types of issues. Using a levels adjustment layer in combination with a color range selection, Richard is able to greatly control the lighting in a photo. The equalize command is also covered in this video tutorial.

Chilli plants will thrive on a sunny window sill or in a greenhouse. They have a long cropping season, so you could still be harvesting fresh chillies in December. You will need just two small pots to sow your chilli seeds; use a good quality seed compost and keep them in a bright place to ensure they germinate.

SUBMIT: Cell Phone Photo of a Silhouette by January 9th. WIN: SuperHeadz Wide and Slim 35mm Camera

In this week's Phone Snap Challenge, we would like you to experiment with lighting and mood setting to create a silhouette. A silhouetted photograph contains a subject that is defined with an outline, appearing dark against a bright background. The subject generally appears dark, without any detail, while the background is bright and more exposed. Silhouettes in photographs appear to be simple, yet they can convey a sense of drama and emotion. Before you get started, check out this guide on h...

News: Jupiter and Venus Rising Before the Sun

Right now, Jupiter and Venus are rising in the early morning hours just before dawn. I went outside on the morning of the 4th of July and saw Jupiter and Venus right next to each other with the Pleiades (The Seven Sisters) just above them and knew that the next morning I was going to have to get up early and set up my tripod to try and capture what I saw. I used my Panasonic GH2 with the stock zoom lens set to about 40 to 50 mm equivalent and with the aperture open to about f/5. I set my ISO ...

News: new Lite Panels announced at NAB

I think this is a fun new product from lite panels.   There are clearly some important specs still being left off this announcement, such as FC readings at different distances, initial lumens, and a better sense of the nature of this light.  Can it spot and flood like a fresnel or is this just another soft source in a round housing?  Hopefully this will be a nice step forward for LEDs and the slow but steady death of tungsten lighting.  

News: Timelapse Footage of a Moonrise

This is a really quick video I took of a moonrise last year. It has been sped up by a factor of 8 and was taken using a 2600 mm equivalent lens (75 times zoom for a 35 mm lens). The mountain it is rising over is about 40 miles away.

Fresh Folds: Turtle Evolution

Last week I found the time to work on my own origami designs again. The basic turtle from a few weeks ago developed: From the basic turtle on the left (in darker green) I derived not one but two different turtles (the yellow and the one in bright green). As you might see on the pictures in the gallery the new turtles are both prototype and folded a little unclean.

Eye Candy of the Day: WiFi Networks Visualized

Norwegian designers Timo Armall, Jørn Knutsen, and Einar Sneve Martinussen visually capture invisible WiFi signals by light painting signal strength in long-exposure photographs. The trio set up a four-meter long WiFi-detecting rod with 80 LED bulbs to depict cross-sections through the WiFi networks of various Oslo neighborhoods. Armall says:

News: Now Thats eating Fresh!

The two fast food restaurants, Farmer Dinner and Burgerville both run their restaurant in a way that supports their local farmers. This provides freshness to their customers. “Our mission is to increase the economic vitality of local agrarian economies,” (Murphy). That’s a bright idea in which local restaurant should take in consideration. We the people should consider the support of local farmers. This will stop the extortion that happens in other countries and stop fast food chain restauran...
