Adobe Photoshop tutorial slides

I think, is the easiest way to level to think like a transparency for over head projectors.  You know the old style projectors people customer responses to PowerPoint presentations?

Nowadays of course, you have the fancy LCD projectors, but back in the days of the old school who had to put these transparency sheets on a projector and it can be to put drawings on the screen.  The nice part, however, was that because had to light most of transparency show, just that transparent.

This has several slides on the projector-stack for you and create a composite allowed.  A composite is together a collection of multiple images or elements that arranged to make a final 'composite image'.  In fact that it is a batch of pictures, so arranged that it a new image, one not made before there.

So let's say you had a transparency of a tree.  A transparency of a hill.  A transparency of a sky.  And a transparency of a cloud, and even a Sun.

You could set the sky transparency first, then the Hill.  Now you would have a scene with a sky and Hill!

Next you can the clouds which add Sun and structure.  The final resulting image would be a nice picture.  If you wanted to you could move the structure and the structure to another location.  You could move around the Sun or the clouds.  You have a lot of power and flexibility.

Not only remove you can move an item, could you you completely.  You could for example take the structure or the cloud.

You can again order the elements and a new scene.  For example you could set the sun behind the cloud, by you the transparency for the Sun in the cloud.

Could the same to make the cloud appear either behind or in front of the tree (a tree should be).  You get the idea, you can do what you want.  That's the point.  With each of these elements you control the composite image and make it what you want to have.

The same applies to layers in Photoshop.  Simply create layers, these layers (by Draing on you, for example) elements, and arrange the order of the stack layers.  Layers on the bottom of the stack are behind layers that are at the top of the stack.

This means that if a layer at the top is something on this level drawn over top of anything else will show up.

If a layer at the bottom of the stack, it can be easily concealed by other elements, the layers above it.

It is so simple and so powerful.  But you know what?  It is not only also opacity and layer blending modes have the order of layers that controls how the final composition will look like.  But that's for another article.
