White balance in real life

This goes for fellow photographers especially for those that the white balance that is in almost every camera has not yet become completely automatic and invisible.

I ordered those custom-made shades that allow me to trigger white balance in real life i.e. to see warmer or colder tones by just looking upwards or downwards. If you look up to someone (in a metaphorical sense), you will see them in a warmer (more orange)  tone, if you look down on them you will see them in a colder (more blue) tone.

3D IR

Have you every seen Infrared with your naked eyes?


Here is your chance through the first infrared video in 3D. Enjoy it in HD!

IRgraphy

Last week I thought of a very affordable and elegant technique for painting in 3D space with infrared technology.

You only need the following items:

1. Digital (preferable with liveview) or Film Camera. You must check if your sensor can detect infrared; To do so, just flash any remote control towards the camera and you should see the invisible IR light on the LCD of your camera.
2. Any remote control -- I am sure you have one at home, if not, get any universal one ($5-$25)
3. Any Infrared filter that fits your camera. I recommend the r72 filter that allows IR spectra beyond 720nm. Most remote control IR wavelengths range between 920nm and 960nm. You can find filters online ($20-$75) or you can build your own cheap IR filter with red and blue transparent plastic or glass sheets but I recommend the former for better quality. 

Now, you need to set your camera to manual and set the shutter speed to at least 5 seconds to give you time to paint. Turn the shutter and start painting with your remote control pointing towards the camera lens. I anticipate some examples made using the technique detailed above using a Pentax k-x and a 50mm lens:

SLR + InfraRed Filter

Eventually you will get bored of shooting landscapes and portraits until you can afford a lens upgrade, a trip to a remote place or find a new inspiration.

A very affordable ($10-$50) change of perspective  can solve your problem and get you inspired for weeks if you are up to the aesthetical challenge. An infrared filter allows into your camera's sensor only photons traveling with long wavelengths, mainly above 700nm. The most common and recommended filter is the R72, which filters light waves above 720nm. Infrared filters are known to add an eerie yet dreamy feel to your pictures as illustrated below (using R72). 

Infrared cameras are very sensitive to light, whereas more commercial SLRs need to be adjusted in order to see through the almost opaque infrared filters. Personally, I adjust the exposure to +4 EVs (about 16x slower shutter speed or faster lens) when using the filter and I use a white balance that is similar to that of indoor yellow light. State of art in lens production becomes a ball in the ISO's park with the inevitable noise for action shots or hand-held cameras (in contrast to using a tripod). I resort to ISO 1600 or 3200 when tripod-less.

With IR, any regular place can be turned into heaven with some skills and composition. Lamentably, the latter is not an easy game with a quasi-opaque filter. Therefore, you can either shoot blindly and then get feedback through the playback or you can compose without the IR and then attach it when done composing.

I hope you enjoyed this trip along with the slower photons. Bon voyage!
