Need filetypes explained in lay-terms, please

[CTW]

I am working with a printing lab that requires sRGB files. I have tried to determine whether paint.net files are sRGB (and which file types are or aren't) by combing through threads, but the language is just too over-my-head.

The Color format for my computer says it is RGB.  Does this impact paint.net's capacity to create sRGB images?

I'm not a filetype expert, maybe @null54 could answer this one.

This is more a color management issue than a file type issue, sRGB is one of a number of standards that describe how RGB pixels should be interpreted for display/printing.

It sounds like the printer is asking for an image with an embedded sRGB color profile.

 

Paint.NET does not currently support color management, but you should be able to use Krita to save an image as sRGB.

sRGB is the standard color space on Windows 10

The sRGB standard color space was developed jointly in 1996 by Microsoft and HP.

It is the default color space, but can be changed by installing other ICC color management profiles

BTW
There is a open source freeware called Cyan that allows for the conversion of ICC profiles for images up to 32 bits. I use it to convert RGB to CMYK. Here is the link:

When you goto Windows Color Management you should see something like what is inserted below after selecting the 'Advanced' tab:

How do I know if a file is an "embedded sRGB color profile?"  Is there a way to check?  Thank you!  
P.S. What does it mean for a file to be "embedded"?  And "embedded" as opposed to what kind of file(s)?...

Really simply: an "embedded sRGB color profile" means the image has it's own table of colors which it uses to make sure the image displays the same way across different platforms.

Embedded means the file contains the color profile as opposed to that the color profile is stored in a separate file or does not exist at all.

Here we are full circle.

 

If you created or edited an image in Paint.NET and did not add/embed a color space profile to the Color Management, then it will saved as sRGB by default.

Paint.NET does not provide the option to add/embed color space profiles, it uses the WCS 1.0 default or the profiles installed by the user via Color Management.
 

Why?
 

Because: "When no input color space is specified, by default WCS 1.0 uses the sRGB color space as the input color space for color mapping.

When no output profile is specified, but a default device is specified, WCS 1.0 selects a default output profile. If the default device does not have an associated profile, WCS 1.0 uses the sRGB color space as the output profile."

I just found an excellent video link on the basics of color space and profiles:

Paint.NET will preserve the EXIF color profile from any image that it loads, mind you. It just won't make any use of it in-app.

[HyReZ]

@Rick Brewster

If the image is edited in some way will the resulting image loose any of the EXIF data such as shutter speed, f-stop, camera model, or stuff like that when saved?

 

I guess I should try it see for myself.

No. All EXIF and XMP metadata is preserved. I think the only EXIF data that Paint.NET might change is the DPI, if you modify it in Image -> Resize or Image -> Canvas Size. There is also some precision loss that happens for DPI, e.g. "96" becomes "95.997", which hopefully I can find a workaround for at some point.

 

Oh, also, PDN will honor the rotation metadata (90°, etc.) when loading an image, but then discard it.
