ICC Profile - Panasonic Lumix DMC-FX9

Thank's for the answers.

When you say sRGB, is it the "sRGB IEC1966-2.1" that I have in
Photoshop ?
If understand, you recommend using the sRGB as the working RGB with
Photoshop
but I've seen elsewhere that they recommend "Adobe RGB (1998)". What
is the difference ?

I'm printing my photos thru an internet photo printing provider that
gave me his icc profile.
When I want to do a prewiew I use the menu "View | Proof Setup |
Custom" and I
chose his icc profile. Is it OK ?

Another question

I'm using a scanner for 35 mm color films. It is an Epson and I have
his icc profile.
Should I convert to sRGB also when working in Photoshop ?

Yes, that's the current version of sRGB ... note it's not what you
asked for, "the icc profile of my Panasonic Lumix DMC-FX9" but rather
an abstract "working space" profile used for editing, which is
different from a "device-specific" profile.

AdobeRGB has a wider gamut or range of colors and is typically used for
people printing on high-end printers making larger prints. sRGB has a
smaller gamut and is used for web images and most of the quickie
printers. Your camera has a wider gamut than sRGB so you are throwing
away some colors, but given where you are printing you probably won't
notice a difference if you decide to make two prints, one edited in
sRGB and one in AdobeRGB.

Yes, this is called "soft proofing" and you are doing it right, though
you might ask what they suggest for 'rendering intent' (either Relative
Col or Perceptual), this could make a difference in how you see it on
the screen. Also enabling 'simulate: paper white' will dull it down a
lot, more like you see on paper vs on a backlit monitor. Basically if
their profile is accurate (not a certainty) and if your monitor ICC
profile is very accurate (likewise not a certainty) then you will get a
pretty good preview of what the print should look like.

This article explains soft proofing pretty well ...

Panasonic cameras use sRGB profile as do nearly all P&S digital cameras.
Unless you have a particular need to supply pictures to commercial printers,
you should only work in sRGB mode in Photoshop with these type of images.

You'll find that nearly all photo quality inkjet printers produce very good
to excellent results from Photoshop after editing your photos with this
profile if you use "print with preview" and choose "same as source" for the
print space profile. You can then rely on the paper selection of your
printer to obtain the colour you see on the screen... Provided you have that
screen balanced for colour. There are a plethora of free programs around to
do that with.

sRGB IEC1966-2.1 is just the version of the standard in use by Adobe. There
are plenty more RGB standards but for simplification, stick with sRGB. The
profile; Adobe RGB is a wide gamut profile used by commercial printers and
magazine publishers. It displays more variation in colours but at the
expense of a dull looking image. If the camera takes sRGB, it is a moot
point to convert it to a standard wider than that unless you have a need for
specific gamut past what sRGB produces. You know, most photo labs using Fuji
equipment, convert any file you give them to sRGB in order to print it.

The profile supplied by your photo printer is peculiar to his particular
printer. When I need to provide a file with a peculiar ICC profile, I apply
it to the image after it is edited in sRGB. Sometimes this results in the
image looking off colour on your screen but the photos come back looking
right.

Epson scanners (the ones I've owned) all use sRGB by default.

This is not strictly true. Cameras embed the sRGB profile and present
RGB numbers relative to that gamut, but that is not the profile of
the camera device itself.

Sorry, that slipped away before I could summarize as:

distinguish between profile and working space.
