I went to a computer store to check on maybe getting a new mac....
Not much you can do with them out of the box on display, so I ended up
dialing my own website and I was shocked to see that a lot of the
colors were way off. First I suspected the stubborn mac 1.8 gamma, but
the photos looked good actually.
My work method is to make the pages in PS CS and slice them up into
jpgs with sRGB tags. All the side-by-side slices are the same
100,100,100 Grey from the same psd file, but were showing as different
densities from one another by 10-20%. Safari, latest version that i run
on my stable 10.2.8 - all are showing exactly the same grey on my
profiled monitors - 20" cinema, 17" LCD, 2 powerbook LCD's and 2 CRTs.
Safari in 10.3.7 were showing these slices like a patch quilt on
iMac's and cinema displays ranging from 20-30".
I tried different display profiles on my displays, but could not
recreate the problem on my computers.
A few .gif files that looked the same on my Safari and almost the same
in IE - OS10.2.8 - was much different grey on OS10.3.7 and Safari. I
left only one animated .gif for now....
I downloaded from the web server all the files and opened in PS. All
grey measured 100,100,100 and looked exactly the same in PS ( i copied
them on top of each other and could not tell where one image tone
started and the other ended) and all showed to be tagged sRGB . No
error message and looking at assign they showed as sRGB.
It was not till I had redone from scratch (with type etc) all the files
that looked different grey and saved them all over again that things
started looking closer, but not close enough - i may have to redesign
my whole website, which is pretty extensive and I'd be limited to white
or black i guess....
I have to run over to the computer store to check, because they still
look fine on my 5 macs running Jaguar.
Also checked OS 9.2.2, which was fine.
I did come to a few conclusions and a suspicion...
IE does not seem to color manage images that function as roll overs and
there is a 5-7% difference
and with cm turned off in IE there are 1-2% differences still. Again:
roll-overs and all the images with grey are a perfect match in OS10.2.8
and Safari. Also a perfect match opened in PS.
I wonder if I inadvertently used grey jpgs that may have had different
rendering intents. Perceptual on some and colorimetric on others, but I
doubt it since I simply used a different setting in the "color
settings" in PS when i do web work.
... so gurus - what's going on here and what can i do to save my web
site design ?
thanks for any thoughts and help furthering CM in he real world.
