no reason to. If they're already JPEG, the damage is done. Just save any you work on as TIFF to avoid further loss and you'll be fine.
Also, RGB TIFF images compress VERY nicely using ZIP or RAR.
That's what I mean. I want to save them all as TIFFS so that way any work done to them isn't accidentally saved as a JPEG and, therefor, compressed more.

yeah i invented some colors that pantone doesn't cover
there should be a very similar equivalent. Select the color, then go into the color picker. See the next to the new/current window? the one with the little box drawn in isometric over it? That's the nearest pantone version.

alright, a note on Halftone paterns.
When you are printing something, it uses the additive color method. It doesn't actually mix the inks, it uses a halftone pattern to create the illusion of them blending. You've seen this in newspapers, most notably.
A black and white gradient halftone, enlarged, looks like this.
Now, to get a four-color process print on an offset printer, you have to burn four plates for the ink to travel on. The halftone patterns for each color are set up at various angles to prevent moire patterns. I'll explain this in a minute.
Here's a good graphic that explains how this works.
The angles at which the halftone screens must be place in relation to each other in order to avoid a moiré pattern from forming. The common angles used are black at 45°, magenta at 75°, yellow at 90°, and cyan at 105°.
If the patterns are not aligned jsut right, you get strange bands and waves through your picture, which is called a moiré pattern. Like this:
You see moiré patterns in scans of comics quite a bit, for instance.

alright, enough of that shit for now, unless someone has a specific question.
keep going if you want, this is really interesting
I don't know what else to cover, unless you guys have specific questions. I don't really know what else you guys want to know about. It's such a god damned complex program I could probably go on for hours about whatever, but I don't really want to do that without some sort of direction.
ah, the days when loading a 30 meg ps file would take 20 minutes...

first thing I do with a new computer any more is boot up photoshop to see how long it loads, then create a 8.5x11 300 dpi image, fill it with Filter>Render>Clouds and then rotate it 12.5 degrees.
That will push a processor like crazy, and it is a great test to see how well it handles math-heavy computations like that.
Rank, will you teach me how to photoshop? Cause damn, you know more than I do.
what do you want to know?
Uh, shit, hold on. I'd have to review. I've got a wide assortment of questions i've built up since I started teaching myself photoshop. Fun fact; I've only been using photoshop for about 8 months now. Before then I didn't know how to color anything.
fedora, tell me about how you get the wonderful textures on your drawings

Yeah, that guy's not me by the way. That's just the dude I borrowed the brushes from. He does crazy stuff.
He even makes MSpaint look good.

fuck, cal was asking about levels and stuff.
I wrote up a huge tutorial on using adjustment layers, including adjusting levels and using the selective color tool, and firefox freaked out and I lost it.

GOd damn it.
I learn more from being shown and interacting than reading stuff.

THAT IS FUCKING AWESOME! Thank you.
open your brushes pallete, then click on the dropdown. Select "save brushes" and save them as something.
Pretty straight-forward.

My brushes are an ancient chinese secret, found here: http://www.deviantart.com/deviation/55088505/
There's about 30 of 'em, ranging from faux water colors, chalk, detailed line shading, authetic glow, etc.
They're all I use nowadays. I'm such a ripoff artist.
