    digital photography
  • a photographic method that stores the image digitally for later reproduction

  • Digital photography is a form of photography that uses an array of light sensitive sensors to capture the image focused by the lens, as opposed to an exposure on light sensitive film.

  • (DIGITAL PHOTOGRAPH) Simply is a photograph that has been captured electronically on a hard drive (storage device) or converted from film to digital format through an electronic scanning process.





    polarizing filter
  • (polarizing filters) Used on camera lenses to selectively remove excess light.

  • A common filter that removes reflections from water, glass and other surfaces, it also increases colour saturation.

  • A photographic or optical filter that polarizes the light passing through it, used chiefly for reducing reflections and improving contrast. Two polarizing filters are often used together, such that rotation of one of them results in a neutral density filter of variable density

  • The polarizing filter used with most modern cameras is a circular polarizer. The first stage of the polarizer is a linear filter which filters out light that is linearly polarized in a specific direction.

23/365 - Late Night with Frustration O'Brien





Ugh.

This photo took about an hour to get right lighting wise (let's not even bother mentioning that I could have had a better pose), and another forty minutes or so to process it in Photoshop until I ended up with something I was remotely happy with.

Things I learned on this image:
* Remember to take the damned polarizer off the lens BEFORE you get frustrated that your long exposures aren't coming out right at all
* Can lights suck for backdrop lighting. So do the shitty stage lights I bought off eBay last year
* I need more speedlights, and they either need to be synched, or cabled together so that I don't have to keep moving my SINGLE flash all about in order to expose different parts of the image
* Get a stand to mount the flash that is aimed at my face, because holding it out in front of me in my hand yielded variously random annoying shadows and glare depending on the angle I held it at
* Sit MORE still during a 15 second exposure so that I don't have a ghostly outline
* Don't bother attempting something this complicated at 2am when I have work at 10am
