Originally posted by dosdan I based the WB on the camera response to a blank white screen page in Wordpad. It's 5000K.
Does your K20D tell you what colour temperature it sees? That'll be a cool feature.
Anyhow, good for you that things line up well in your case. My comments weren't not exclusively targeted at you but meant for anyone who may want to try this method.
Is 5000K the right temperature for viewing pictures? I know that it is 6500K for movies but that is probably a different case.
BTW, regarding the difficulty to find the maximum moiré: I asked the inventor of the moiré method about a variation I came up with and he responded that he thought it should be admissible: Slightly tilt the laptop screen and then the moiré pattern will move up and down the screen when you refocus. At its centre position, sharpness is optimised at the centre (camera needs to point at the centre). Not sure how much this helps. Never had the time to fully explore various focus adjustment techniques and validate how well they apply to real world shooting.
It would be interesting to learn from those who have applied the moiré method to see whether it leads to adjustments so that
- focus chart tests show no BF/FF (with tilted / non-tilted targets)
- real world results are as desired
For cameras with no live view, the moiré method isn't as convenient, but connecting the camera to the laptop and using Remote Assistant is perhaps an acceptable second best solution.
