I need some help around calibration - I need my monitor to provide accurate colour / brightness contrast for both Web display (I presume use jpeg and SRGB) and for prints (presuming TIFF aRGB).

I shoot RAW and process to 16 Bit TIFF using Capture One Pro as Adobe RGB. Am I right in assuming when I open in Photoshop CS2 I should convert to SRGB if web is the ultimate destination and leave as ARGB if print will be the final destination?

For reference could you please evaluate the colours / brightness of this shot, as processed using a newly created ICC profile with a free download of WiziWYG (I know i'll probably have to buy a colormitre thingee...)

The image should appear bright (not too dark) and saturated with little to no over exposure. Plenty of blue in the sky, the lake should have a distinct cyan to it and very should be rich orange reds around the boats. The first boat was desaturated to pure white, so should not have a blue or red cast. There should also be plenty of visable detail in the tree on the right.

Any thoughts and assistance greatly appreciated , Thanks!

Basically the image I see is as you describe it regarding the colors ... however ... the entire image is somewhat muted like it could use a bit more contrast.

When viewed in Adobe Bridge this image is not tagged with a Color Profile.

I see the image exactly as you described it. I do NOT have a colorimeter-calibrated screen, I run adobe gamma about once every two weeks and check a few reference images to make sure I'm looking at something that visually resembles what I get in prints.

Oh and while I wouldn't describe the image as a very high contrast image, I would definitelly not call it muted based on what I'm seeing on my screen.
 
I'm intending to get a color calibration system (spyder & software) for my monitor. Gathering info around the net.

I didn't come up with a clear answer to select a specific product between

pantone huey
gretag macbeth
colorvision
lacie (not mentioned a lot strangely)

Anyway my lcd is not calibrated but I see the image as you described. The contrast looks great to me and the colors are just lovely!
 
My point is regardless of what application you processed the image in; the Color Profile is not attached to the image you posted.

Here's a comparison of your image with one I know is was saved in the sRGB color space. Your'is on the left...you'd notice the missing Color Profile line

Sorry - Adobe Bridge?
This was processed in CS2 and converted to sRGB for web...

Me neither. Looks 'LAB-ish' too. ;-)

This is what it looked like when I opened it in PS 7. I converted the profile to sRGB, saved and posted. The water looks more cyan in this one than in your post. gc

 
Sosua,

First off, forget about calibrating a monitor for web output. There is no color management going in in web output and unless the viewer's monitor, calibration and viewing criteria exactly matches yours, there's no way you'll get matches for even the majority of systems out there.

As to your reference print, we go on the above which states that we don't have a common ground. Unless our monitors were side by side, we really have no reference points for making an evaluation like this.

Also, the frontmost boat does have a blue cast in the front and also the rear, more so on the top rear. You have extreme blocked shadows that wouldn't print well either. I did a quick tone mapping using what looked like the best neutral light source on the front boat to give you an idea what can or can't be conveyed by monitor viewing:

Then you need a device to calibrate your monitor. Asking others to evaluate the colors of your photos is no way to calibrate your monitor.

Right, or at least make copies and convert to the different color spaces, but as others have said your posted image is RGB98 not sRGB.

Bite the bullet, buy a good calibrabing device, learn to use it properly, then trust it.

Thats odd about the 'blue cast' as I can assure you the first boat was completely desaturated in CS2 - it may well be an 'optical illusion'?

Could you please explain and reference the 'extreme blocking' - on my display all shadow detail is well visable - it could well be my monitor is still too bright :(

Thanks for your thoughts, would your advice then, given no web colour management, to just keep everything in aRGB? - every time I save for web in CS2 the jpeg ends up 30% more desaturated than the TIFF...

If you run the eyedropper in PS over the areas I mentioned, you will see the blue channel is saturated more than the other 2.

My monitors are calibrated toward print output and match pretty well for the intended output I use. The blocking is irrelevant to monitor viewing. The eyedropper once again shows the values, some of which are in the sub 5,5,5 RGB range while other blocked areas are around 10,10,10 which is borderline for most printed output.

Keep your workflow totally in aRGB but you MUST convert to sRGB for the web. If you're seeing the big color shifts you mention, you could have a corrupt monitor profile.

Can I guess?

LAB'ish adj.

1. a photograph or other image that has been converted to L*a*b color space in Photoshop and has then had curves applied to the a and b channels to increase saturation in a more pleasing way than an RGB hue/sat adjustment would do it.

And as far as I'm concerned LAB'ish would be a compliment.

I like some of the colors it can get which is easier in LAB, but duplicate-able in RGB with more fiddling.
