I like your work JR.
Always have.
#1 pulls me two ways.
as a portrait...leaves me wanting/disapointed.
as an editorial or art peice....leaves me wanting to know what she's thinking/feeling. almost haunting expression.
#2 I'd consider removing two highlights from the eyes and some dust spects from the shirt....B+W would add to the charm of this model. very engaging eyes.

I wish I could give you a fix.
but i'm stumped.
it's running real well on my systems.

maybe it's bad ram and a highly improbable coincidence, (that it showed up at the same time you upgraded.....)?

ok.
I got it running on tiger, on a g5 and an intel macbook.
no problems here. I also have cs2.
It's gotta be an adobe issue with leopard. drop them an email.
maybe they'll get a patch done soon.

I'm still running tiger.
try this:
open your aperture presets and uncheck the shadow/highlights tool
save a new preset with that unchecked.
re-launch aperture, and don't use that tool.

see if that has any effect, then try this:

try this: open system prefs.
set displays color to adobe 1998.
then open aperture.
then set color back to your norma profile.
I had some issues with my monitor profile that caused wierd aperture behaviour.

let me know if that helps.

if not, here's something that may make you feel better....
Apple will get it sorted. they have too many pros using cs2 with aperture, and no one else to blame.

that's why I held off before installing.. you never want to be first to buy, first to install, and first to find he glitches!

I still got leopard in the box and haven't installed on any of my macs yet.
will do it when I can afford down time.

keep me posted.....I'm upgrading at least one of my machines....r u using the k10?

I have aperture 2.0 in the box at home (been staying in the city alot this month marketing my business) will try to install on one of my machines, later this week.
but I think it's an issue of migrating images from one version of aperture to the new version.
my guess is your images settings is applying some sort of adjustment to the files. (shadow highlights, or color or something). Are you bringing the library form an older version or straight from the camera? what adjustments are being applied at the import?

is it trying to generate new previews for your entire library?
if so you might let it run overnight to finish up and try it in the morning.
here's a good resource with archives you can search:

I think the problem for me is not knowing what the camera settings were.
on the one hand wide open apertures on landscapes don't make much sense...dof suffers, and lenses perform poorly. Under controlled circumstances, these issues never really show up (ie studio portraits where shallow dof is desirable).

in a landscape f8-f22, plus grad nd's plus tripod and timing (early/late in the day) seems to resolve enough of the problem that post processing eliminates the issue easily, and it just doesn't show up as a problem...

I'm looking at that shot, and am left wondering "why?".
Other than to test the lens's limits on ca/pf I can't think of a single reason to bother turning on the camera.

Whenever an unplanned photo op presents, you are left with two options:
A) you got interesting light, and must find an interesting subject/composition.
or
B) you got a great subject and need to find a good angle to get the light.

Without either great subject material, or great light...why bother snapping a photo at all?

underwater housing or wrapping with sound dampening material...
