you got a while? because i will help you. but i dont know how different CS2 is from PS 7.0, which is what i have.

1. As far as the "fill paint can tool", i think this is what you are talking about..



the 1st icon pointed at allows you to just fill in an area with color. If you have something selected, and then you go to Edit>Fill, a box comes up with a few simple options, and then click OK and it will fill the selection.

2. When it comes to making sigs, its all in your imagination. Photoshop allows you to do whatever you want. But for the examples you posted, ill try to explain what had been done.

1st sig- In this one, he selected the car(Bascially, he took the polygonal lasso tool OR the pen tool and make a selection of the car) then inversed the selection so it was the BACKGROUND that is selected INSTEAD of the car (Ctrl+Shift+I), then he went to Image>Adjustments>Desaturate. This made the background black and white, but left the subject (the car) in color.

refer to the picture below for the steps i explain...
he made a pattern fill that makes all those little lines/squares/texture/whatever. Step 1-To do that, go to File>New. When the box comes up, make the size of the new image Width 5, Height 5. Also, set the background to "Transparent". then click OK. Step 2-When the new image comes up (reallllly small) use the magnification tool and zoom in all the way(1600%). Then use the pencil tool set to the smallest size and make a square in the upper left hand corner, like in the picture. Then go to Edit>Define Pattern. save it as whatever you wish.

next, (Step 3) go to an image you want to apply this pattern to. Go to Layers>Layer Style>Pattern Overlay. in the box that comes up, click in the pattern selection box and find the pattern you just made(the box with a square in the left hand corner)Then click ok. You can play with opacity settings to get it how you want. Thats a basic pattern fill.


3. With the picture of the Tiburon, same thing, except he pasted a picture of his car onto a picture of a water fountain, trees, and a building. The background image was desaturated(made black and white) and his car was pasted on top in full color. he also did a pattern fill here, but with just straight lines. Same steps as above, except instead of a little square in the top left hand corner, he put a straight line.


4. the eclipse is my sig. I just changed the brightness and contrast, and then added the username and a border. more on that later..

5. Same thing as the tiburon, he just posted a pic of raven riley(sooo hot) onto a picture of his 240. changed the opacity of raven riley a little, and blurred out the edges of her. rather shitty sig, imo.


6. as far as clearness and color, it depends mostly on how you change the brightness and contrast. Image>Adjustments>Brightness/Contrast..

notice the two differences..

the one on the right is clearer and brighter. her shirt stands out a little more, the car looks sharper. it all depends on you and your imagination.

anything else you need, just hit me up. im always down to help out.

btw, your car is clean as hell!
