It indicates your document colour profile does not match your work space profile.
So, PSE3 workspace is set to RGB and any image that is not RGB would be astericked.
To be correct, if your workspace is set to sRGB and the document you open is in another colour space then you get the *.
Similarly, if you have Elements set for AdobeRGB and the image you open is in some other colour space, you'll get the *
These are the only two options you have. It's just for information only.
Is there a plugin for PSE3 or a stand alone application that can convert RGB images to sRGB for the web?
Colin is correct, "RGB/8*" does indicates your document colour profile does
not match your work space profile. PSE4 works as Colin said. However, you
said you have PSE3. PSE3 works a little differently -- you can only get
"RGB/8*" when you have your color settings set to "Full Color Management".
If you have your color settings anything else, you won't see that.
You asked "So, PSE3 workspace is set to RGB and any image that is not RGB
would be astericked.
No, not quite. First of all, let's go over what "RGB/8" means. The "8" part
is easy. This is just the bit depth of the color channels. In this case 8
bits per channel. The "RGB" part is the color mode of the image. If the
mode were Grayscale this would read "Gray", Indexed mode would read
"Indexed" and so forth. Since yours says "RGB", the image is in RGB mode.
PSE3 only supports a few color modes. RGB is one and Grayscale, Bitmap, and
Indexed are the others. If you try to open an image in an unsupported mode
such as CMYK or LAB, you'll get a popup message saying the mode is
unsupported and there will be a button to allow you to convert to RGB mode.
The "*" on the end has to do with the color profile associated with the
image. Profile and Mode are not the same thing. The mode describes how
colors are represented (RGB says that each color will be represented by a
Red value, a Green value, and a Blue value). By themselves, these are just
numbers in the range of 0 to 255. Determining what those numbers mean is
the role of the profile which decribes how these color values are to be
interpreted. There can be many profiles for the same mode. Adobe RGB and
sRGB are both RGB profiles and are probably the most common. There are
other RGB profiles as well.
When you set your color settings to "Full Color Management", you told PSE3
that you wanted it to use Adobe RGB for the default internal working color
space. However, this setting will also attempt to retain any color space
profile which may be embedded in the image. The "*" tells you that PSE3 did
just that. Your default color space is Adobe RBG but your working color
space is something else -- most likely sRGB, but other RGB profiles could
have been embedded instead. When you see the "*" in PSE3, your work space
profile is not Adobe RGB, you are using the embedded profile.
PSE4 is improved over PSE3 in how it handles color management and profiles
and can do limited conversions between sRGB and Adobe RGB. You might want
to consider upgrading to it if you need to convert Adobe RGB to sRGB often.
Bob, you have been very helpful and I appreciate this information which I have saved.
My Sony DSC R1 assigns the RGB color space and PSE3 opens the image with out questioning when PSE3 is set to full color management.
If I shoot in sRGB PSE3 works the same in the full color management setting.
When I compare the RGB and sRGB image in PSE3 the histograms are slightly different.
The sRGB has a wider spread of the dynamic range (0-256) but the height of the pixels in the histrogram are not as high. When you look at the two images the sRGB image is a bit (no pun intended) brighter especially the greens.
PSE3 shows "*" for the sRGB but not the RGB. Overall I think I got it.
Thanks for your help.
Some additional clarification.
You need to understand that the the Working Space setting has no affect on your image if it has a profile associated with it. The Working Space is for new images created within Photoshop or images that do not have any tagged profile.
What is important is that you calibrate and profile (if possible) your display. It is the display profile that is used in the translation of the colours from your image colour space to the display.
As AdobeRGB and sRGB have a different gamut it is possible to see shifts in some of the colours.
Your camera has three color modes: standard (sRGB), vivid (sRGB but distorts
range by decreasing brightness and boosting saturation), and Adobe RGB. It
also supports RAW mode. PSE3 will process your raw mode images if you
download and install the latest camera raw plugin (version 3.3) from the
Adobe web site (http://www.adobe.com/products/photoshop/cameraraw.html).
"Full Color Management" will use the embedded profile in your images instead
of the default color profile established by your color setting. If you
shoot in sRGB you will work in sRGB. Likewise, if you shoot in Adobe RGB,
you will work in Adobe RGB. This is exactly what you want it to do.
Adobe RGB and sRGB are both RGB color spaces but they differ in terms of the
gamut and representation of the colors. They both have their place. From
your description of the differences you are seeing, it almost sounds like
you set your camera to "vivid". The camera setting you choose will write
out the color settings to the jpg image to match the profile so you will see
differences in the histogram. That's normal.
You might want to consider shooting in RAW. When you do so, you are
capturing the raw sensor values unprocessed and you can defer the selection
of a color space until you actually process it in Elements. The camera raw
plugin in Photoshop will let you choose the color space in the plugin.
Elements doesn't do that in the plugin (at least PSE3 doesn't, I don't know
about PSE4) -- it uses the default color space as established by your color
settings. "Full color management" will result in an Adobe RGB image and
"Limited color management" will result in an sRGB image.
Be careful with the color management settings when processing images that
were not shot in RAW. In PSE3, "Limited color managment" will always assign
an sRGB profile ignoring any embedded profile (unlike PSE4 which honors the
profile). This is not good. For an example, take an image you shot using
Adobe RGB and open it while the color setting is "Limited color managment".
The colors will appear less saturated and less contrasty by comparison with
the original Adobe RGB image. The same thing happens when you view an
Adobe RGB image on a web site with a browser that doesn't support color
management (most of them don't). This is why you want to use sRGB for
viewing on the web.
>at least PSE3 doesn't, I don't know
No difference in PE 4.
Bob, thank you for the information.
I have saved it for reference.
It's great to have a forum that explains issues and more that you can't find in the owners manual.
