Corrupted User Profile

Ducks a Lot
Ducks -- NEX-5N & Olympus OM 24mm f2.8.

I logged into Windows and found that my normal user profile can not be loaded.  Tried to restore/fix but to no avail and was forced to delete and recreate the user profile.  This causes all my settings in Windows to be lost, including the settings in Photoshop.  Even though I set the colour profile to sRGB, and the colour looks normal in Photoshop, but after uploading it to Flickr, it's become over saturated, like the one you see above.  Since I am not a Photoshop guru, this will likely take me a while to fix.  Frustrating!

  1. Hi Yu-Lin,

    this is an unpleasant surprise. I regularily back up my drive data, but such a thing of course always occurs before the next backup -(.

    I noticed that you use the OM 24/2.8. How would you rate it compared to the kit lens and the Vivitar 24?
    Best regards and good luck in fixing it,
    Chris

  2. Blame colour-management? I've always had to strip out that from any photos i push to the net, and leave it in people's monitors' "hands". Just like the rain, if you resolve you'll get wet, it feels OK.

    Photoshop has a habit of desaturating things, doesn't it.

  3. @Crix: yes it was very inconvenient, but not fatal, so it wasn't too bad. I like the OM 24mm f2.8 and it's one of the better manual focus lenses out there at 24mm. My copy has some fungus at the rear elements, but is still very good.

    @uv: Thanks. I have decided not to have a default colour profile and everything seems much better. Seriously, I only use Photoshop for RAW conversion and slight adjustments.

  4. The camera has a colour profile and photos coming out of it have that profile. Then photoshop has to match that to your display profile to allow you to work with it. When exporting, it makes sense that the photos would typically get your display profile as the adjustments have been carried out on that display. But depending on your photoshop settings PS may decide to stick with the original camera profile and only adapt what it's displaying to you. Then the browser displaying any image online has to decide how to handle the colour profile information (i.e. if the image has your display profile there's no change. But if it has the camera profile still, it has to be adapted). Now for the crux of it: Browser makers still cannot agree on colour management. Safari has it on by default. Firefox - I think not, though it's supported. IE hadn't heard of colour management until recently. So between major OSes and browsers and colour settings the probability of something unexpected/uncertain gets very very high.

    For me it wasn't an easy decision to strip colour profile from my photos. Regardless of what you use an image editor for, the point is to always display the image as best and as faithful to the original as possible on every display out there. That's the point of having a colour profile in the first place. Why that doesn't work still beats me.
