I would appreciate some help with what probably is something really obvious.
This only recently started happening.
First of all, my display is calibrated and profiled.
When viewing and working on images in Photoshop or Lightroom they look fine.
When I convert to sRGB for posting to the web they also still look fine.
But when I use the "SAVE FOR WEB" command, the "after" in the "2-up" mode
looks too red and saturated.
Same thing when I export from Lightroom to a web gallery. The images look
fine in Lightroom prior to export, but too saturated and red on the site.
I tried converting an image to sRGB first. Then saved as a jpg and reopened
in Photoshop. It looks fine.
This is very puzzling to me. Any ideas?
I took a screen capture from the "save for web" screen. Although the
difference is not quite like I'm seeing on screen, it gives you some idea.

The color space the picture is allready in. In the days of Photoshop 6
and later there is no reason to change the working colorspace unless
the customer demands it.

So the lesson to learn: make shure you know source and destination.
Add some "requested" fields to your order form.

True, but either you have to educate them or you have to make an
educated guess.

That is the reason why the destination has to be specified. An sRGB
picture is not a good candidate for an ISOcoated offset print, while
an ISOcoated image is not something you want to offer for web design.

True, but either you have to educate them or you have to make an
educated guess by asking the right questions. Communication is key
here !
> This is the reason why I ask - which color space is better?
Either the color space the image is in when you receive the file, or
the destination color space that fits your customers requests. And
perhaps you have to deliver more than one file (that is the reason why
I love CaptureOne Pro - one click and you get an ISOcoated for offset,
a sRGB LoRes for web, a sRGB mid res for the Uncle Robert/Aunt Sophie
job, an ECIrgb for a professional archive or perhaps a ProPhoto 16bit
- some tiff, some jpeg - just check or uncheck your preset
destinations with a click as needed for the current job)
Just my 2 cents
Karsten
