The making of transparent phones

This is just some behind the scene explanation of these transparent screen photos I've made for this post:

As a perfectionist I obviously cannot settle for the shifted colors, black borders and rough edges left over from keying. I've never done this before so i came up with a number of slightly different method for each of these shots. I'd say they all work just fine.
  • Without professional lighting equipment, white balance is probably the biggest issue, extra steps had to be taken to adjust for the different color temperatures of the light source and the screen.
  • My camera, phone display and monitor are all decent in color consistency, This would be extremely difficult with less accurate equipments.
  • Shooting in RAW really helps with the adjustments in color temperature and exposure, as well as keeping things in 16-bit and wide gamut before outputting final image.
  • My tripod sucks, sometimes the background and phone shot are not perfectly alined I had to manually adjust them.
  • Geometric abbreviation can be a pain in the ass because you would have to warp things into curved edges instead of straight ones. This has to be avoided at all costs with the choice of lenses and digital correction before working on the images.
  • Exposure control is important, the image coming from the screen has to be exactly the same brightness as the real scene, or the low dynamic range of cameras will make it obvious. Shooting in RAW with a good camera can be more tolerant but you have to physically match them as close as possible for best results.

This one is different because that is the actual screen shot with the camera all in one shot. It isn't a software screenshot pasted on top of it.
