•  You should have a total of 4 layers now of your 'background'  - one regular, one mirrored, one with screen effect, and one motion blurred. 

•  Remember your tube?  Well let's paste it in for a few overlay effects.  I pasted it again, this time only sizing down by 80%, put one on one of the sides then duplicate and mirror it.  I then applied blend mode of Burn at 34%

•  Now!  Remember that main tube layer you pasted right at the start?  Duplicate her and move it below the main tube you'll have.  Apply a Gaussian Blur of about 10.  (Adjust > Blur > Gaussian Blur in X5, should be similar in other versions).  

•  On the blurred tube copy, we are going to apply Feedback effect - Effects > Reflection Effects > Feedback and apply the following settings. 

•  Drag the effect all the way over to the right side of your canvas, make sure this layer is underneath your main tube layer on top.  Duplicate it and mirror, merge down so they are on the same layer.  Change the blend mode to Screen, leave at 100%

•  Duplicate the layer and change blend mode to Soft Light, or whatever you think looks good.

•  Almost done I promise!  Come on you can do this!

•  Remember those 4 layers of the background?  Select all of them, click the Link button on your layer palette, like so and press it:

•  Go to Layers > View > Show Link Set - this enables you to grab ONLY the layers you want to see, and you should now see your background effect, no tube, just effect.  Go to Edit > Copy Special > Copy Merged.

•  Now click undo until you see everything again after you have your copy merged grouping, paste that layer above the copy of the tubes you put above the ones that were on the sides.  Apply Staci's mask that I used (or any to your liking really).  I applied Overlay blend mode to it.

•  On top of ALL of your other layers, including the tube, paste the copy merged again.  Select All, contract by 2 and hit delete.

•  Under this layer, add a solid color with your flood fill tool, I chose a darker color from my tube.  Select all, contract by 4 and hit delete, select none.  On this layer, go to Effects > Edge Effects > Enhance More.  I also applied DSB Flux Bright Noise to this because I like sparkles LOL.  I chose Mix option and a higher number, mine was at 65.

•  If you wish, I also added a blank layer above the mask, grabbed my brush tool and added a texturey brush, using a darker color from my tube, not needed but it added a smidgen of darker effect for my background.  I put the blend mode at Overlay.

•  Add drop shadow to your tube and the frame layer you made.

•  Add legible credits so they are readable at first glance.

•  Add any text or wording that you wish at this point. 

•  Save and you are DONE!!!!

I hope you have enjoyed this tutorial and I didn't confuse you tooooooo much.  I love my blend modes as you can tell, you can add so much depth with them!
