View - Proof Setup - Custom..
Profile
sRGB IE61966-2.1
That just makes the color space a standardized RGB and helps, especially to proof your colors when printing & just to make sure you are seeing what others will.
Guess if it's critical, use it. I forget most of the time and have been OK without it (so far). |

What about the intent? what setting and do i check the box use black point compensation?

I've always left them at default, which is Relative Colorimetric and Use Black Point Compensation checked.
?
Maybe someone else can explain the uses better?
I just remember having an issue with a DPCPrint and that was what was suggested to do.

Why do you care about this setting? |

Because it seems to make a diference on the photos... i tried to change it when i had a photo opened at it changed the colors of the photo... now it should make something diferent but i really don't know why it makes it diferent.

The most common usage for proofing is to get a sort of "preview" of what your image might look like when printed using the corresponding printer profile. Accuracy of the profile is critical, but calibration of your hardware (monitor) is paramount. Some settings would allow you to preview what the image might look like on a (generic) mac or pc.
Your lab might provide you with a profile, which you can use for this purpose, although you should find out if they require the image converted to the printer profile (or something else, like sRGB or AdobeRGB) first or if they (lab/printer) can deal with color space/profile conversions automatically.
Ultimately, the goal is reduce some of the unknowns, avoid big surprises, and give you output that is relatively color accurate.
When preparing the image, this is usually the last step, since you will likely make final color/tonal adjustments based on the proofing. If, for example, bright, deep reds looks a little too saturated or unusual clipping occurs, you can make the necessary edits to correct and produce a pleasing final (printed) result.
BradP's usage is unusual and I really wouldn't recommend it. It can make sense in some contexts, but I would generally avoid it unless you have a firm grasp of color management and/or soft proofing. Stick to the basics and you'll be happier (in the short-term anyway).
Oh, and read this book for the real deal on the subject: Real World Color Management

Reason I suggested that:
DPCPrints Forum Hits
Was also what was recommended by them on an issue where I was seeing something different than what got in a print.
I do agree monitor calibration is probably more critical than anything lese. |

That's a lot of stuff to read. The first couple of hits didn't seem to match your suggestion. I have recommended created such a proofing entry (call it "web') in the past, but that assumes one knows the implications (having to convert the sRGB before publishing).

I guess if dpcprints is your target, then keeping every sRGB is what they want (mostly because it simplifies things for them).

Different strokes for different folks. Do you shoot RAW or JPEG? Do you convert to 16-bit or 8-bit? Do you edit in anything other than sRGB?
If sRGB is your bag, proofing will only be useful if you do printing at home and have a profile.
If AdobeRGB is your working/editing space, then you have to be more mindful of what happens when your image is being prepared for printing or the web. Generally speaking, you want to convert to sRGB prior to publishing to the web. For printing, it depends on a number of other factors. Many labs accept images in AdobeRGB just fine though.
If editing in AdobeRGB, BradP's suggestion will work if you want to edit your image while it's still in AdobeRGB, but see a preview of the image as if it were converted to sRGB. If you forget to actually convert to sRGB, you'll likely be unhappy with the results.
Why go through that hassle when you could convert it to sRGB earlier in your editing process and then make additional changes in sRGB to suit your tastes? For one thing, you might have clipping issues: one or more colors in AdobeRGB don't exist in sRGB, so if you convert too early, then the "uber smart conversion sub-routine" will try and make a best guess as to the color to use instead (this is the "intent" setting). If that happens, you might find a nice gradient in Adobe RGB turns into a blotchy patch in sRGB or loss of detail in other areas. By deferring the conversion and seeing what will happen if you convert, you can make a more informed editing decision about how to get that nice gradient to look in sRGB.
As for intents, perceptual and relative colorimetric are the only two you'll likely use with digital photography. Perceptual rendering compresses your entire image gamut to fit within sRGB, maintaining tone/contrast at the cost of saturation/hue changes. Relative colorimetric rendering will maintain hue/lightness while changing saturation and resulting in tonal compression. Here's an excellent article, written by Bruce Fraser (one of the authors of the book I recommended in a previous post): Realizing Good Intentions with Rendering Intents |
