Is Depth Of Field Affected By Focal Length? A Practical Test

The fact that the depth of field varies depending on focal length seems pretty straightforward, doesn’t it? Matt Granger however says that wide angle lenses don’t necessarily have a smaller depth of field when compared to longer telephoto lenses:

To understand any of this, you have to know what depth of field is: (Yes, this is very basic) Depth of field is basically the depth of your image that is in sharp focus, it is usually about 1/3 in front of your focus and 2/3 behind it.

In his video, Matt conducts a test to prove his point: He takes the same shot with the same framing and only changes the focal length and the position of the camera. The aperture was kept the same – f/2.8 – throughout the shoot. Of course when changing the focal length of your lens you’ll have to physically move the camera if you want your final result to have the same crop.

Here are the results:

Dancers Painted Metallic Silver Compose This Innovative Nude Portrait Collection [NSFW]

 

CYBELEA project that has been many, many years in the making for photographer, Guido Argentini, has come to blossom as his latest book, Argentum. The project was sparked in 1995 when Argentini made his very first photograph of a silver coated model while working on establishing new and unique ways to create studio portraits. Since then, Argentini has been masterfully assembling a collection of images that feature his innovative take on nude photography. Argentum is 100 of of the photographers favorite images from the collection.

Working with dancers, gymnasts, and aerialists to serve as the models for Argentum, Argentini painted his muses in metallic silver paint and photographed them in front of a white background. The results are incredible as you’ll witness below.  [Read more...]

Watch: A GoPro Gets SLo-Mo Scorched In Flames During A Failed Rocket Test

rocket-launch-03

Copenhagen Suborbitals is the kind of project we like. They are a non-profit, DIY-driven, Arduino-powered project “working towards launching a human being into space, and bringing him safely back to earth“. This is interesting because most projects I know of only care about the getting to space part, and leave the safety back bit.

One of the development phases involves building a rocket engine. It would be a simple task, it is not rocket science after all…

Wait, it is rocket science. This is why every step is tested again and again to insure it is working. On August 20th, the team did a static test for their HEAT2X Engine (one that does not try to lift a rocket into air) and luckily had a GoPro 3 camera strategically placed right under the engine. The footage show an inferno on earth in 240 FPS.

I’m still trying to decide if this would be a dream come true or a hair raising experience (or both?), but one thing is for certain it’s definitely a once in a lifetime moment. I caught up with Canadian based photographer Jim Lawrence, who was in the right place at the right time when this curious grizzly bear decided to have a closer look at the photographers Nikon D800.

The Westcott Eyelighter Will Give Wonderful Eyes. In Camera

eyelighter-02

One of the holy grails of beauty retouching is perfect eyes. Actually, getting good lighting on the eyes would probably be one of the first things you would lean in a beauty retouching workshop, maybe after perfecting skin. One of the “secrets” to getting good light on the eyes is getting a slight moon-shaped highlight on the bottom of the eye. Dave Piper covered that a while back on his eye’s retouching tutorial, but what if you wanted to get this in camera?

I just stumbled upon this great lighting modifier over at Neil van Niekerk’s Tangents blog. It is called the The Eyelighter and only does one thing, but it does it well: It provides a light that gives an arched reflection in the eye.

Yes, you read that right, now you can get yourself a beanie with a pocked that’s dedicated to hold a lens cap or perhaps a shirt with an integrated lens cleaning cloth?

DIY: Slider (With Bearings) For Under $100

bearings-slider-01

Time and again we show our love for sliders as creative tools. They provide some sweet production value at little cost and effort. Now most DIY sliders that we feature here are either friction based (with the build trying to minimise friction) or aligned-skating-wheels based. It is kinda rare to see a build with the smoothness of bearings. And this one by Jones Oliver is under $100.

With more and more people turning into makering, more maker-dedicated shops are popping around and Jones mostly used the parts from one of those stores for his build:

Rapper ‘Presto Flo’ Falls Into Harbor During A Photoshoot

We’ve all seen A LOT of fail videos all over the web because it’s almost impossible to not see them and while they’re all entertaining to an extent, I haven’t quite seen any video that’s as hilarious as this one:

The person in this video supposedly is “Presto Flo”, a rapper from Florida who was shooting “Promotional Images” that day. Let’s just say I’ve seen shoots that went better than his… A small gust of wind and…. Better the ocean than a 100 meter dive down a cliff. According to the video description on YouTube he landed on an oyster bed and had to be taken to the emergency room.

We’re ending this with a PSA: watch whats on your back when you have your pictures taken

Quick Tip (GoPro Beginners): How To Set Smooth Slow Motion Videos

If you’re not familiar with video editing and camera settings then shooting slow motion video with a GoPro can perhaps be a little frustrating.You may keep wondering why your new GoPro Hero4 slo-mo’ed footage is jittery and jerky. It may be because you need to sync the camera and editing settings. MicBergsma is here to help you out in this situation though: in his short GoPro Quick Tip he demonstrates the best way how to get the smoothest videos possible.
