How to make this shadow effect

[gsmalarm]

Hello, I'm new for photoshop.
I find majority of products with a great shadow effect like below picture:

I know there is a layer style can create shadow, but I can not make it like above.

Anybody can give me some hints or maybe some tutorial?

Thanks in advance!

Use the ellipse tool, create a black shape ellipse...

Then add a gaussian blur to it then lower the opacity.

Also make a copy of the image you want to put a shadow under, then reduce the opacity of the new image layer pull the corner or centre tab down to invert (make upside down) the new image, place below original - adjust lighting and opacity some more when happy, along with Inkz addition it will look the nadz.

Or you could follow this tut I made a few days back...

Slightly different but the same principles.

This is the technique Inkz and Paul described in their posts.

Excellent tutorial Sam. I have a suggestion to add for when the situation calls for it.

You may want to have your reflection tilted or off angle from what it is when you flip it. To do that, use the transform tool, hold down ctl/cmd and pull the corners to reposition the angle. Or you can use transform>warp.

Additionally, to make your reflection a bit more glossy, you might try using overlay blend mode. But that is just a guess. For a B&W image, vivid light might even work, opacity lowered of course. Maybe even an inner glow could help . . . The image you are showing is probably a photograph? So the reflection is onto a shiny surface which would give that glow.
