Tutorial 1

What I did here was I opened the layer and saved it as a copy in png format first. Then I selected the sign with the magic wand tool and  erased it completely, revealing the white layer behind it. After doing so, I then applied a sepia tone and a tie-dyed texture to it, whose opacity I had to change to 15. I then changed the sign layer to a smart object and made the background into a new layer. I then created to solid fill layers, one white and then the next red with both at a 15 opacity. Lastly, I added a pattern fill layer at a 50 opacity and voila!

                            (To be honest, i have no idea what it's actually supposed to be.......)

Rainbow Bright

What I did here was I downloaded the futurama font in order to type the words "rainbow". I then selected each letter in the word and gave each letter its own color of the rainbow I then rasterized the text layer and duplicated it. Using Cmd+Click on the layers mask, I selected the word, pulled out the rectangular marquee tool, set the settings to "Intersect with selection" then released the rectangular selection halfway through the letters. After doing so, I gave the copied text layer a motion blur, giving the text rainbow streaks. I then applied a white-to-transparent gradient from the middle of the word up to where the letter "b" ends. After typing the words on the bottom, I put a gradient overlay over the small words with the angle at 0 and set certain locations while giving each location the same colors of the rainbow as the larger word.
