    CONCEPTS: Layers

    Layers:
    If you can imagine layers as a transparent muliti story buliding. When you look at it from the side, you can see all of the different levels or layers. On layer one there is a red box, on layer two there is a blue object. There is also an orange ground floor (we’ll call it the ‘background’).



    Now, if you were to look at the building from above down through the roof, you would see something like this:





    Eveything on all of the layers appears as if it is ‘flat’, yet you know it’s not.

    How is this practical in the graphics world? Imagine you wanted to move the red box up to the top right corner. If you simply cut it out (without using layers) there would be a hole left!

    With layers, however, we can simply select that particular layer and move the red box to where we want it. Since that layer only has the red box on it, the others are not effected.

    Hope this makes layers a little bit clearer

    Nice one Plat! :-)

    You can also describe layers as clear acetate sheets (like overhead transparencies) stacked or layered on top of each other. But a building works well too. ;-)

    Some programs (like Image Composer -- I know some of you use it! ;-) use 'sprites' instead of layers, but they're basically the same concept. Some programs (like MS Paint -- Please tell me none of you use that! Please! ;-) don't have layers or sprits and as such are nearly impossible to edit, unless you have an extremely steady hand...

    Please don't call this thread Graphic Theory. While the explanation was quite good, it only relates to SOFTWARE and not to design in general.

    If you're going to discuss why a line looks good in a certain position and at a certain angle then THAT would be graphic theory. If you're going to discuss why a particular font works in conjunction with this image or that image then THAT would be graphic theory.

    Not trying to be a jerk so please don't take it that way. I'm just reflecting on this article that I read on A List Apart yesterday. It was very telling.

    That's a good question Plat. I don't know. It's not a Photoshop specific answer because tonnes of applications use layers now.

    Possibly:

    -= Graphic Design software tips

    Anyone else have a suggestion?

    Hmm.. I think Graphic Design tips or Graphic Design techniques might cover the load of the tutorial quite nicely.
    It is personal liking, but I am not fond of the word software in the thread's title.

    Read the article creole, could make an intersting discussion out of that.. but anyway why not call it

    "Tools: Layers "

    im sure we could get a few more tools threads such as brushes and the like

    I agree.

    This could open up others doing things like Channels, and Layer Modes etc as they are awesome tools, but as far as I can see a lot of users, well... do not use them and are not really sure what they do.

    ( although I suppose it shouldnt be too PS orientated)

    Possibly:

    TOOLS : Layer Modes (Photoshop)
    TOOLS : Layers (Generic)
    TOOLS : Brushes (Generic)
    TOOLS : Something PSP only does (Paint Shop Pro)

    etc
    etc
    etc........

    You're both tools

    I wouldn't describe a layer as a tool for some reason...

    Design Methods maybe ??

    Possibly too vague, maybe 'Understanding layers' or something.

    I would rather see a layer called a tool then "design method"

    Hmm.. why does the subject of the post still read Graphic Theory: Layers? Isn't that changed along with the thread title?

    Nope, posts are independent of threads (which is why only Advisors can edit thread titles)

    anything that lets me put pixels on the screen can be a powerful art tool. I can do things with MS Paint that I can't do with PS, PSP, or Illustrator. Plus its simplicity sometimes can't be appreciated enough. You can always take what you created there and use it in PS or one of the others. Plus its much easier to WhiteBoard via MSN Messnger than share app Adobe Illustrator :P

    I agree completely, especially when you can see the pixel you're about to place.

    Like what? Those advanced fill efects

    I dont dissagree MSpaint is workable when you've got nothing else, but you can't exactly do much to images
