What you are seeing there is not a Panasonic reds-in-white issue but my
Neanderthal approach to working with mixed lighting. The alcove they are in
front of is lit with fluoro lights. Left unaltered it produces a sickly
green tinge to the background whilst the body of the church (including the
dress) is normal daylight with overhead incandescing lights directly above
the couple... Sort of every photographer's perfect lighting situation! LOL.

Magenta is easier on the eye than the horrible tinge of a fluoro light. This
is a picture highly descriptive of what "Mixed lighting" is all about. You
can't filter for daylight without producing a green tinge where it is most
noticeable. All I did was correct the whole scene to a warmer looking cast
by use of "photo filters" than leave the important part green.

There is no magenta in the dress of the original image, just a horrible
green tinge to the background. FZ50s do have a problem with saturation of
red. They are after all an RGB camera using a sensor derived in many ways
from Panasonic's television cameras. Panasonic has a long way to go before
they reach the right balance.

All my FZs have too much yellow and too much red. If you shoot 2/3rd of a
stop under to prevent UV in white dresses blowing, you actually increase the
saturation as you lift the shadows. I use a "droplet" in Photoshop to alter
the hew +10 and pull the red and yellow saturation -15 and -20 respectively.
The images then look as good as any you'll get from a Canon 20D. Which
incidentally, also need to have manipulation of their images to render them
natural too.

Have a look again and you'll see an image I reduced the warming filter from
25% to 8% on. I personally think the first picture was more pleasing. The
green light influence is still prominent.

Apparently, not too easily for the idiot who posted the pic.
His long-winded excuse-filled explanation could have been boiled down
to, "I'm too stupid to figure out that Layer thingy."
