Huh? I can see a dozen instances without magnification.One spade at least.
Remember the old reticular activator? It went off bigtime when
I saw that photo.
The sun was illuminating the sky within 20 degrees of that skylight
opening. The fringe effect is directly linked to the amount of spectral
highlight that exists near a dark silouette and this does show it.
Notice that spectral, blown out sunglints and windows just as far off
optical center don't show it at all, just the extreme skylight. Of
Ok, let's go over it closely. Get out the magnifier. I'm using the
magnifier in Win98 at 6X. Fire up Photoshop if you must.
1. The skylight. Obviously. Purple on the upper left, green on the lower
right.
2. There's a purple halo around her body on the left. It extends up her arm
and over her head. On the inside of her right forearm is the green.
This halo is the first thing I noticed.
3. Left edge of the close window is purple, right edge is green
4. Sun spot on the floor. Ringed in purple. From the center of the image
out, if there's a transition from dark to light, it's green like under
the table at the top of the spot. Where it goes from light to
dark it's purple.
5. Sun glints off the chairs are blown out of course.. purple mostly but
some green.
6. Rear skylight. Purple edge above, green edge below.
There's repeats of a lot of this in different places. About half of those
I can see with the naked eye. If you go poking around CP950, and lots
of other cameras' albums at 4X to 6X you'll see it EVERYWHERE, even in
non-blown out areas. The only images that don't just jump out
at me are from the Sony DCS F505, which really needs to be pushed hard
to do it.
What's puzzling me is why you don't see it.
The main thing that hilights how unnatural the color is is to see it paired
with that green. The green is an almost exact inverse to the purple.
You could dismiss the purple about half the time as possibly natural,
until you see the two together where there's a dark - light - dark
or light - dark - light transition.
It does NOT require that you blow out the whites to make it happen either.
All it takes is a certain level of contrast between darker area and lighter
area to make it happen. If you've got a medium light area against a pure
black it'll stand out. Pure white against grey/brown, likewise.
I ain't making this up. I couldn't find it much in your studio shots,
but they were fairly smoothly lit, and there's not much else of yours up
for public consumption for me to look at.
However, let me see if I can prove my point. Here's one of your
metavision shots.
Ok, obviously, it's lit in blue light from the top/left.
Not what I'm interested in.
Run the magnifier down his zipper near the bottom. The zipper isn't
blown, but look at how there's a row or two of pixels with a
green tint down the left edge of the zipper, and again a couple rows
with a purple tint on the right side. If it weren't for the fact that
the green is paired with the purple, we could argue that one
all day. Together, it's indisputable. Add in the fact that
the green is always on a dark to light transition from the center
of the image out and purple always light to dark, and we're done.
