Preparing our sticker

What should I do before I start on the holographic effect?

So before we start on the real work we need to prepare our sticker so we can fill in the right values.Open your sticker as one image. We do this because we have to select the whole image. Get the quick selection tool by pressing W on the keyboard or by pressing the quick selection tool in the toolbar. Select the whole sticker and press CTRL+C to copy the sticker to your clipboard. When you are 100% sure that the sticker is in your clipboard you go to the tab called channels which is located right next to the tab layers on the right side of the UI. Create a new layer and call that layer "Alpha". The screen will go black but you are able to see your selected area. When you have the layer Alpha selected you paint the whole selection white. When you've done that right click on the layer called RGB. Choose the option delete channels. You should be left with only 1 layer and that is our Alpha layer.Now you're going to create 3 new layer and you name them, Red, Green and Blue. In every layer you paste the sticker in your clipboard by pressing CTRL+V. When you make all the layers visible you should be able to see the following. What have done? Well we have converted our image from an RGB channel to an multichannel image. This way we can do our edits and later on convert it back to an RGB image We are now working with a so called Cyan, Magnata and Yellow image which is translatable in a color pallet. Now that all the stupid boring stuff is done we can finally let go of our creativity and start giving our sticker an holographic effect in the next paragraph!!
