Questions about truecolor settings
Hi,
I'm using the true color settings on a jvc hd200 but when I shoot at max zoom I have a lot of chromatic abberations. Is that normal or not? Can you post me the last version of the truecolor (3.0 I suppose)? Thank You, Marco. |

The CA of your lens has nothing to do with the true color settings scene.
At the stock-lens one should avoid Iris no less then F2. On your HD200 you can adjust in your menu a little bit of the CA through the 'shader' settings. Do the adjustment at the F4 stop at a uniform grey background.

The White Shading adjustment won't affect the colour fringing you are seeing on the long end of the zoom but will balance out any magenta or green tones you see at the top and bottom of your image. Once you set a value for your lens you shouldn't have to set it again. As Marc said set your aperture to ƒ4 and point the camera at a white or gray flat surface. Then adjust the Green White shading parameter until there is no visible green or magenta at the top/bottom of the image.

Hi Marco.
The latest version of all my config files are at my website: http://paolociccone.com/blog TrueColor for the HD200 has no version 3.0, 3.0 is for the HD100, the HD200/250 model had just a minor revision from the original. Anyway, you can find it at the website and like others have mentioned, CA is a property of the lens not the config file. Buona fortuna! |
