Wrong color space?

Please don't laugh but I have no clue what to call it... :D

I am working on a DVD sleeve and I noticed that my curves are on Magenta Cyan and such instead of what I am used to working on RGB... I thought nothing of this till I saved the progress as a .jpg and uploaded it to get a weird message from my browser about not being able to display the image because it has errors?!?

After a little panic attack about the stability of my system I remembered the color setting...

a. is the the reason?
b. how do I change it?
c. what do you call these color "worlds"? :tongue:

Thanks in advance!
 
a) maybe
b) in Photoshop: Image -> Mode -> RGB (for RGB (video, computer, anything emissive) colorspace) or -> CMYK (for CMYK (printing) colorspace)
c) colorspaces

Oh cool thanks for the answers!
I was afraid it was a different name and I would sound dumb.

So Mikko...

d. can I work on RGB and then save to CMYK to submit to my printing house? I guess that's the way it works... there is no loss of resolution or any other type of degradation, just a different expression of the same values right?

EDIT: oh crap it is asking me to rasterize my smart objects... so maybe I'll keep working on CMYK and if I want to share the image on the www then I'll save a rasterized RGB version... next time I'll start in RGB and do the opposite. Right?

ALSO:
e. my bit-rate was set to 8, why not go higher right? It puts the switch in the history but no problems.
f. why is my 32-bit grayed out? is it because I am working on HVX images? couldn't it process in 32-bit anyway?

D - You're better off starting in the color space that matters the most. If you're focusing on print, work in CMYK; if the client needs to see an RGB version (on their computer or regular printer), then save an RGB copy for them.

When you convert to a different color space, you'll usually lose color information. RGB has a wider color gamut than CMYK does, so converting from RGB to CMYK will usually hurt you.

E - 8 bit color resolution is standard. When you switch to 16 bit, you would do so to edit the image color-wise. For example, when editing curves, you could switch the 16 bit color resolution. The problem with that is it takes up twice as much memory (2 bytes for each color instead of 1 byte). The other problem is several of your filters only work with 8 bit color.

F - 32 bit color is for HDR images. Basically, it's using different exposure settings with a digital camera. I think your camera has to support the feature though...

Tommy! I ought to get out of my favorite sections more often. I have been having a great time here and I see many of the usual suspects.

d. important stuff... RGB having colors that have no translation means the color would be changed. Is that correct and what you are referring to? Did I get it?

e. Aye! I wondered why not all filters were available... why would that be? the filters themselves were not developed with 16-bit capabilities as if they were third party software? I did native I hit close to 1.5GB of usage with Vegas and PH running. Refresh did seem to get slower.

f. ??? lol... I think I follow... I guess 32-bit color is just that, colorspace, not the bitrate at which PS is doing it's math. So I guess you'd need a digital file in the format. Did I get that?

EDIT: Waaaait.... I just took a look at your link and HDR = High Dynamic Range, as in those photos composed of two pictures one exposed for the highlights and the other for the shadows? I heard abotu that a few years back but haven't really thought about it much. I got it now, thanks!
