Thanks Thierry,

I'm very impressed with the shadows, and DR.

Best,

Mitchell

 

[thsinar]

yes, right.

Unfortunately, I am still having problems to get the right colours rendered in the posts: my images are way different and much more appealing than the one you can see here, concerning colours.

I have now tried more or less everything, when posting: I have tried to use "sRGB", "Adobe RGB 98", "ProPhoto RGB", ...

But all those profiles DO NOT change anything when the images show up here, all are as if there is no colour management at all.

I know that it can't be my browser, since using Safari, so what else am I doing wrong?

Guy: any hint?

Thanks,
Thierry

Thierry are you using 'save for web' on Adobe after choosing Srgb as your output profile?

 

[thsinar]

test with a screenshot uploaded with Safari

 

[thsinar]

when uploading a screenshot, the rendering of the colours are spot-right!

Just for you to see the difference.

[thsinar]

no Peter, I don't: should I? Where, in PS?

Sorry for my ignorance!

[Graham Mitchell]

Thierry, are you using "convert to profile"? I always convert to sRGB then use "save for web" in CS3. That seems to work fine.

 

[thsinar]

OK, Graham, got it: it looks much closer now, to the original, though not a 100% concerning saturation.

At least I've learned something.

Thanks, also to Peter,

[gogopix]

yes
the bluish tinge is usually adobe or prophoto space sent to web where it is 'assumed; to be srgb.

For some reason 'convert to web doesnt get it right.
in "Edit" at bottom see "Convert to profile"

Victor

PS There is a simple program called "Hypersnap" that gets a good screen capture, gets the space and also shows pixel dimensions!

Graham,
I agree this is the better route (Edit > Convert to Profile > (make selection in pop-up window), as I believe otherwise, the "save for web" action creates an untagged RGB file whenever it sees anything other the sRGB as the color profile, and that is probably what is throwing the colors off in the shots that Thierry posted.

Alright, here another try, this sRGB and saved for Web:

These look much better, Thierry. There will be some difference from aRGB or Pro Photo RGB color space to sRGB, which is a smaller color space, so sometimes you can lose saturation or increase contrast. It is worth playing with a bit to determine what works best in the conversion (Perceptual or Relative Colorimetric) for your black point. This can cause either compression/shifting of out of gamut colors into the smaller color space, or just dropping the out of gamut colors. That can sometime result in color shifts and changes in saturation, depending upon where you started.

Thierry Mac or PC . I will send you Jacks action for the web

 

[thsinar]

Guy,

I'm using a Mac (ProBook Intel)

The latest upload is the best (closest) I can get, though not 100% in terms of saturation. Here the way, as described by Graham:

PS ---> "Convert to Profile" ---> "sRGB" from the Menu

then:

File ---> "Save for Web & Devices ...": there I have set "Standard Windows Color" (the Standard Mac Color" is even less saturated/brighter)

then "Save"

I feel sorry for having hijacked the time of you all, but had to find out to make it look a bit closer to the original.

Thanks all,
Thierry

Thierry (and others that may be interested),
There is a huge body of data around color management, some a great aid, others a cure for insomnia ;-)

I ran across this simple, but effective description that also briefly covers the issue of Relative v. Perceptual compensation, as it may be applying to what is going on in the shots you have posted.

hi LJ,

I agree with you. I had no clue up to now with all the settings required for web upload. Thanks to some little tries I am much closer now: the difference I can accept it and probably due to the smaller colour space of sRGB. I have used here "Relative Colorimetric" and will give it a try with "Perceptual" the next time.

Thanks,
Thierry

Glad to help. The key to help decide which to use is fairly simple. If you have very specific colors on key things that you do not want to change/lose, go with Relative Colorimetric. This will make some out of gamut colors drop out, but it will preserve the key colors you want.

If you want to preserve the full array of colors and are less concerned about some subtle shifts, go with Perceptual. This will compress colors from a larger space into a smaller space, but keep the perceived appearance of their relationships.

Very helpful, LJ.

Thierry check your e-mail . I just sent you a new action from GetDPI that master Jack created . Folks you can also buy this. We have it posted somewhere . But this is a awesome action when you are ready to go to the web.
