Can anyone explain to me how you would make one photo with multiple poses taken at different times into one photo
and can anyone explain to me about selective desat(i know there is a tutorial) but what i'm saying is I can't figure out how to keep for example two colors and make the rest black and white w/o having in color left in the black in white part....
thank in advance i hope someone can help me:)

Selection Masks and/or layers for desat, and you are going to be using Layers to "stack" your different shots on top of each other for multiple photo composition.

I don't think this is what you mean but it is the same theory using Layers to combine photos.

What Photo Editor are you using?

about the selective desat:
1. what software are you using?
2. does it need to be "legal" for basic challenges?

using adobe photoshop cs2
and those are like what i mean...i'm wanting to do them for a senior picture

try using layers to control your selective desat
create 1 layer in color
put a duplicate layer in black and white on top
use a layer mask with the B&W and paint back the color where you want it

actually, a similar method is used for painting the people back in...the one i did like this was shot with camera on tripod so everything would line up and only "me" needed to be revealed by layer masking

edit to add that I can't find the forum thread....anyone know which one it might have been?

not dumb...i'm being sketchy because i use Elements 2 and don't have layer masks...there's a work-around but you wouldn't need it
meanwhile, i found 1 of the old threads here

As for layer masks and making specific selections, you might want to check out one of the current mentorship threads here. It is PS specific and has lots of great info.

In regards to DeSat:

A very simple way I use from time to time...

1) Duplicate the background to a new layer

2) Change the background layer to b/w, destat or whatever effect you wish

3) Use the Eraser on the top layer to allow the background (with effects) to show through where I want it to.

This definitely will work but it's hard to reverse if you spot a problem with your erasing later. In the immediate you can probably use the history brush to fix a problem. Masking, on the other hand, allows you more control...and you can even use a reduced opacity brush to paint back only some of the color. This second method I'd definitely use if I were going for an "old-time" hand-tinted look.

how do you mask?

I'm taking the liberty of quoting one of my team member's (

cloudsme) instruction posted in our team thread...hope he doesn't mine. ;/
"Hit Ctrl-J and you will create a duplicate layer. Desaturate the whole photo in the new layer the way you want it. (I use channel mixer) Create a layer mask using the icon on the bottom of the layer pallate. now hit the letter "d" This will give you black and white on your color selection. Make black on top by clicking on the thingy between the black and white if you need to. Now select the brush tool. Pick a brush you like, soft edged works better for me, click on the white square on your new layer. Now paint the area you want to resaturate. If you make a mistake, switch the brush to white, and you can undo what you painted."
(I believe these instructions are fairly accurate.)
note: i think the icon he's referring to looks like a little camera
