Steroscopic Rig Requires Only One Camera

September 8, 2010 by Caleb Kraft 16 Comments

[courtervideo] shares an instructible with us on how to build a mirror rig to take stereoscopic pictures with one camera. We’ve had the thought “couldn’t you just do that with some mirrors?” when looking at a dual camera rig. Well, as we all suspected, you can. There are some advantages here, a single click gives you your 3d image or video without any post processing, and unless you just happen to have an extra camera lying around you can save money there. You do however lose some resolution compared to two separate cameras. This setup could actually add some steps if you were wanting to interlace your images for viewing on a 3d tv.

Controlling The Power Of A Flash With A Tv Remote

September 3, 2010 by Caleb Kraft 8 Comments

For those who do fancy photography, setting up the lighting ends up being one of the larger tasks of each session. There are flashes out there that can be controlled via a remote control to help ease the process, but they can cost a considerable amount more. [Dsvilko] shares with us a fairly simple circuit that allows you to use a tv remote to control your flash. He’s using a picaxe 08m and he states that before this project, he had never messed with microcontrollers. We say great job on your first microcontroller project. You can catch a video of it in action after the break.

Using Quality Optics With A Webcam

September 1, 2010 by Mike Szczys 16 Comments

[Devon Croy] built a case to join a webcam sensor with a camera lens. The box is a PVC conduit box you’d find at a home center. He used JB Weld to attach four bolts to the back of the box. These are used to fine-tune the mounting plate for the webcam sensor to ensure it’s at the focal point of the lens. The lens connects through a couple of extension tubes to an adapter mounted in the center of the box’s cover plate. The setup above shows a macro lens that takes pretty good pictures.

If you need images of really tiny things you should look into a microscope adapter for your camera.

Take Better Pictures Of Your Projects

[PT] let us know about a fantastic guide to taking better photographs of your projects. It’s a hefty read but well worth the effort. Author [Johngineer] helps us understand how to use simple (and possibly inexpensive) tools like lights, mirrors, and a background material. He also gives some tips on how to recognize what your image processing software is telling your about your photography skills (get the correct camera setup and you won’t need correct your levels in The GIMP). There’s even some tips on photographing LEDs, a topic we’ve seen before, which you’re bound to find useful when trying to make that blinky thing you built into an Internet sensation.

Microscope Camera Adapter

August 20, 2010 by Mike Szczys 17 Comments

[Ben Krasnow] is capturing some great snapshots using a microscope adapter and some tricks. The camera attachment is just a lens adapter ring with a tube added. Unlike other microscope imaging hacks we’ve seen he used a real microscope but found that the pictures had a bit of light distortion to them. The camera sensor was picking up a glare reflected on the inside of the black tube. By adding a washer and repositioning the apparatus he got over that hurdle. The final part of the puzzle is image processing. By taking several pictures at different focal lengths and compositing them he gets killer photos like the compound eyes of that house fly seen above.

Snapping Pics At The Right Moment With A Pressure Plate

August 11, 2010 by Mike Szczys 22 Comments

[BiOzZ] built a pressure sensitive camera accessory to snap pictures at just the right moment. Before turning out all the lights the camera is set up with a twenty-second timer and a three-second exposure. The pressure plate doesn’t take the photo, but fires the flash to catch an image in the middle of the action.

The hack uses a piece of acrylic as the base of the pressure plate. A switch is constructed by placing aluminum tape on the base, and attaching a thin metal strip that is bent to add just a bit of spring. When an object is place on the plate the thin metal contacts the aluminum tape completing the circuit, a change in the weight breaks it. A simple circuit connects to this, using a relay to actuate the flash from a disposable camera. This is perfect for documenting the moment when you exercise that fruit-induced rage that has been consuming you lately.

Guide To Producing Tilt-shift Photography

August 9, 2010 by Caleb Kraft 26 Comments

[Bhautik] is back again with more tilt-shift photography. This time, hes brought us a quite in depth guide to tilt-shift photography. He covers the technical side of how tilt-shift works, showing the differences in several methods. There is a breakdown of different cameras and ease of modification as well as links to several of his past projects. He even shows comparisons between instant tilt-shift Photoshop methods and the real thing, pointing out key things to look for to identify the real deal.
