Options menus to use, will be written like this: [Menu-> submenu-> option ...]. To name the layer of an object, you just need to double click on the layer name of the object, enter the name and press Enter.


The first is to have the image or object to apply the effect, properly trimmed, it will name this layer "object". In this case will use a flower:






Now create the reflection of the object, so select the object and duplicate layer [Layer-> Duplicate Layer ....]: whom will name "reflection".




The window "layers" panel right now, it must look something like this:





Here comes the most important fact for this to be, rotate the object. Select the layer "reflection" and rotated vertically [Edit-> Transform-> Flip Vertical ....]




Now we must ensure that the two figures ("object" and "reflection" match, that is, the bottom layer of the object matches the top layer of "reflection". If necessary we can rotate the layer "reflection", for that, we select the layer "reflection" and rotated [Edit-> Free Transform ...].



before




after:




In this example simulate the reflection that occurs when an object is leaning on a flat surface. So we degrade the image so as to achieve the effect. For this we will use masks, select the layer "Reflection" and enter edit mode mask [Dar click on the button "Edit in Quick Mask Mode", the red square with the white circle located on the left panel]:





Now select the Gradient Tool button [Dar click on the Gradient Tool, is located on the left panel]:






Now we just have to draw a line from top to bottom. Starting just above the layer "Reflection" and ending by 15% before the end of the object figure:




release the click of the stroke, the top layer of the whole will be colored red (remember, we're in edit mode mask, if you do not start out well again, something you did wrong). So now back to Standard Mode [We click on the Edit button Standard Mode, the white box with the white circle in the left panel]:



What we have just done, is a selection degraded, so we see a part of the layer "reflection" enclosed in a selection box (yes, these ants walking around that part of the object XD). So just oppress the "delete" key on your keyboard (I know it's redundant, but I do not want confusion). Depending on where the gradient began Mascara mode, the results will be, but should ever get over something like this:






In my case, I'll need my Fill lower layer:
