OKAY, it's official, I am in fact a moron!!!! ;-)))
I forgot to Convert to sRGB and left it in ProphotoRGB.
CONCLUSION: Safari handles profiles better than the other browsers.
NOTE TO SELF: Remember to convert the damned photos.
Apologies to all

I hate all this technical colour space stuff. Maybe there should be a law requiring photographers to only publish black and whites. That'll solve our woes.

Actually Safari handles colour profiles and other browsers don't at all. Explorer and Firefox totally IGNORE any colour profile data included in the image file. sRGB is the colour space to use because it's most SIMILAR (not the same) as what your browser and monitor will display.

You techno types are confusing me - I'm with kasugai sean here, bring on the B&W!! I've just learned how to 'profile' my monitor and printer and to remember to use the photoshop colour management instead of letting my printer do its own thing, so please, please, please don't confuse me more!!!!!!!!

How do you profile your monitor and printer? I let my printer do it's own thing at the moment. I usually leave the 'colour managed by printer' dialogue box (or whatever it says) in the Lightroom print module checked.

Nice one Negtate, just tested your image in Firefox which I usually use but now that I am looking at Safari and how great your image now looks I might have to switch to Safari as my browser, so much better!
you could set up your export to always convert to sRGB when using for web so you dont forget next time !
So is anyone else using Firefox to browse photos ?

It is dangerous to use Safari to only view web images with, unless your workflow is certain to export only sRGB to the masses. Otherwise you will get the dreaded "looks fine to me" syndrome and 90% of the planet sees it differently. Always good to be sure you are going with the lowest common denominator by making sure your output to the web is sRGB.

Remember, too, that Windows don't have any options for browsers that support colour profiles. So by using a colour profile other than sRGB you're excluding some huge percentage of the potential audience.

@BK.......Who you calling the lowest common denominator.
Where I come from..........That's fighting talk!!!
Good job I moved.:-))))

So why do I get different results when I convert ProPhoto to sRGB in Photoshop than when I do the same in Lightroom?
Any ideas?

Being stupid !!!! I always enjoy reading these threads but I am scratching my head to what you are all on about ?
If this is photoshop talk, then I will just shut up, stand to one side and let you carry on with this banter !

Putting it simply, colour profiles are translators which tell various devices how to output your file and in theory allow you to produce predictable and consistant results.
It's not just a photoshop thing - it works for all imaging so if you are really critical about how you and others see your work then it's worth learning about.

As far as I understood it too, It also allows 14bits of data per pixel to be rendered into a reasonable file size using some jiggery pokerry based on the human eye's sensitivity to a smaller range of wavelengths than that of the sensor. (8million x 2^14 bits of data - would be unmanageable)

Mmmmm.........Lossy......That's not good.........Unless you know it.
I wonder if that's right.
Surely you should use the best........Unless it's for a specific use......
And then jpeg, should be the lossy thing for the web....Shouldn't it?

It's not quite right.
The monitor is not capable of displaying more than 8 bits per (RGB) channel..it's an 8-bit device. So the monitor has a 'device profile' which translates the 14 (or 12 or 16) bit file into something it can display. The important thing is that this is only for display...it doesn't alter the actual data in the file, therefore you are not losing anything.
You only lose data when you convert the file format to one with lower bit-depth. eg, when you go from RAW (typically 12-bit) to jpg (an 8 bit format). It's better to go from RAW to TIF or PSD (both of which can be 16-bit).
As Taz says keep jpgs for web use only.

I think Adobe RGB is technically better for photos (it has a larger colour range) and is better for working on in PS. Don't ask me how two 8-bit colour spaces can have different numbers of colours because I don't know!
I use ProPhoto because it is a 16-bit profile (colour space) and even though you can't see the extra data on screen, Photoshop and Lightroom have more to work with so you can get better results. Working in 16bits slows your computer down though because the files are much bigger.

Yes, I use 16 bit......But not in ProPhoto?
In Adobe RGB.............Never heard of ProPhoto..........
Does your Camera capture in Adobe RGB.......And does it matter if you only take RAW.....As I do.

As I understand it AdobeRGB is not large enough to hold all the colours that your sensor can produce. ProPhoto is much larger and covers the whole range (I think).
If you are shooting RAW then it doesn't really matter which you set in the camera because it's just a profile tag, the actual conversions are done by the RAW converter you use. You can select a different profile in the converter. ProPhoto is available in either PS Adobe RAW or Lightroom and is the best for a 16bit workflow.
This is the info I'm using:

it's quite technical and the English is a bit poor, but I hope it helps.

Colour is a knightmare, it is such a complex equation that I can never be bothered to do anything about it, truth is unless you print something your never going to see it the same from one monitor to the next regardless of what browser you are using.
