Photoshop - Notes on Layers and dropshadows

-First off yuou need a proper selection
-You can copy and paste a selection into another layer or you can drag a selection into another layer
-To turn a layer on or off, there's a little icon that looks like someone's eye, that's the visibility button, it can hide or show you a layer
-To blur, go in the filter menu, then click on filter, and then select a blur (eg. radial blur or motion blur)
-To get a selection back, hold down the ctrl key and click on the thumbnail in the layers menu
-To create a drop shadow on text, first select the text tool
-secondly write your text
-thirdly duplicate it into another layer
-rasterize the copied text
-Put on a transparency lock
-Make it black
-turn off the transparency lock
-Blur the text
-Last step is drag the copied text layer underneath the original text layer
-And voilla, you have created a drop shadow
-To select multiplle layers, selct a layer and then hold shift and click on another layer
-If yopu want to edit the background layer, double click it and then re-name it.
-The short cut to fill is the key Alt+Delete
-ctrl click the the layer's thumbnail to make a quick selection
Rember to name all your layers
-If you ever have some problems, slowly turn each of your layer off, kinda like detective work
