So here i will tell you how u can make a reflection in photoshop very easily.

Step 1.

I took a canvas size of 800X400 with black background. and wrote a word over there with White background.



Step 2.

Now i click on the text -> and press CTRL+J so it will become copy of same text file ->

Step 3.
Now we made the copy text file as Flip Vertical so that it will become Mirror image of the first text file.


Step 4.
We pulled the flipped image below so it will look like this



Step 5.
Now just changed the Opacity of the Mirror image and our picture become ready.



You can try many more options now urself and on any canvas. This is the simple way to make your reflection. Now u can play for Gradients and make it more looks good.
