Using Layers???

Well I really want to finish a skin LOL but its sooo hard to not give up in middle. Anyways a questions, when you work on skins do you work in different layers so that you dont mess up stuff you dont want to mess up? And also like when you use the lasso selector tool to select an area to work on how do you do it perfectly so that you dont select something you dont want. Cus that always happens to me and then i have to undo and start all over again lol.

I dont use layers i just use multiple copies.
First redraw your skin and shade it, save in under step 1. Then add some details and name it version 1 then you can open step 1 again and make different details and save that as version 2. This way you can go different paths on your skin and its not that hard to restart.

i dont use layers or multiple copies. I just press ctrl-alt-z to step backwards in photoshop pro 7... and i try not to mess up to much.

You can only undo 1 time in adobe photoshop 7. Yoda is there an option that lets u undo more.

Any tips for the lasso tool lol im soo bad at it :X

1 time? Gotta be kidding. You can undo hella times in teh history list. Just click at what time you wanted to be back to, before which effects and brush's were done... etc.

I use layers. I use the lasso tool. I copy the image over as a new layer, and draw over it...

Oh, so many options. Adobe photoshop has very flexible features and telling you one way to author images wouldn't be right. I would suggest learning as much as you can about the features so you know which ones to use and when to quickly and efficiently get the job done. Layers are very useful not just for separating out different elements of an images but also for blending modes. You can paint special effects into a layer and use the various plending modes to change how it mixes. Layers also permit a sort of non linear method of image editing because you can separate image elements and try things without comitting to them. For instance you could paint some really clean looking armor then in a layer above it make your scratches and dirt, then in another layer making corrosion and rust then you can either just turn one or the other off or combine them, whatever you want.

Now two methods come to mind for your issue to keep from painting "out of the lines". First is layer masks. Make a new layer and make a selection for the region you think will represent your element. Then click the make layer mask button on the layer dialog and it will not show anything except for what you originally had selected. So you can paint without having to worry about the borders. However it is still actually painting to the layer when you go outside the lines, the mask just causes it not to be shown, however if the excess bugs you then just select the layer mask, select inverse and delete.

Another method is to make your selection then instead of making a layer mask, make a blank layer then fill it with a solid color then turn on preserve transparency. Again this will let you paint carefree. What this does is if you paint outside the lines it keeps the layer's transparency locked so it can't add or subtract from it so if you paint outside the region which is likely 100% transparent nothing will get painted there.

ctrl-alt-z. Its called step backwards in the edit menu.

ok here is the thing layers dont need to be used except for the fact that blizzard put a nice tool so that u can change the amount of red blue green so if u want a red version of ur skin you could do that and then a green and so on

i always use all layers (cept for alpha) so i can see what color it will be in the end

Just set this at the Preferences Windows. You can have as many as you want.
