Many people these days are enamoured with the latest craze of photographing products on a glass surface with the product reflecting a very smooth, liquid reflection. Apple made it popular with their iPhone imagery.
In the old days, we had to go to some fairly lengthy set building in order to accomplish the look, but today you can do it in mere moments.
The object itself has a lot to do with the relative success of this technique. Best case scenario is a good, straight-on product shot. This eliminates the need for oblique reversals which take a lot of time, and need to have a perspective slant in order to look convincing. (See reader's example.)
Creating the reflections
Let's use this shot of a Pentax camera.
Note I've carefully cut it out of the background so no slivers of white are showing. Mistakes in removing the background will be glaring once we build the illusion.
To make the illusion, we need a much larger expanse of background.
Here, using the Crop tool, we can drag the handles beyond the image area and visually estimate the size we'll be needing. Once you commit the crop, the canvas will be expanded to fit the size indicated.
Since any reflection into glass or a liquid is a 'mirror' image of the original, we have to create that copy.
The easiest way is to merely float a copy (Cntrl/J or Cmd/J) and with the Move Tool (Tap V) drag the top, center handle down below the bottom. I'm going to leave the dragged image just a bit compressed. This lends a bit more realism to the scene.
Creating the mirror background
At this point we'll need a background to reflect the image off of. Some people like smooth, level graduated backgrounds, and others like spotlighted. Apple uses sort of a spotlighted background, note where the 'hot spot' is in their images. (Note, if you're using a white-out background, then no graduations are necessary.)
We'll use a Black to White graduation first, just for the sake of this demonstration.
I'm holding the crossover point of the gradation to just below the horizontal center of the scene, and the lighter part never achieves white. I accomplish this by starting the gradient about 20% down the scene, and dragging about 20% beyond the bottom edge of the window. This brings a 20 to 30% gray to the edge.
Now we can begin working with the reflected image.
First set the transparency. I used about 40%, but that will change as we move along. (diagram)
To make the reflection realistic, as it moves away from the object across the glass surface, it gets more faint. So we'll need to simulate that "fall-off" by using a layer mask.
Select the reflection layer, and then click on the Layer Mask button. You'll see the white mask appear next to the layer thumbnail. Click in the Layer Mask thumbnail, and its borders will become doubled to indicate it's selected.
Now, using the gradient tool drag a tight, quick gradient from black to white. You'll notice how the black masks image and the white allows it to show. The reason I'll use a mask here is to adjust the amount of transparance by moving the actual mask up and down. (diagram)
Turn off the lock links between the thumbnails, make sure the mask is selected, and with the move tool, you can drag in your image window to adjust where the gradient falls on the image. Very handy.
At this point we're done.
Fine-tuning Mirror Reflections
... some options and alternate scenarios
I think the black and white is very elegant, but a little too stuffy and formal. Let's add a bit of color to offset the steely grays of the camera. Create a new layer and simply fill it with the color you like.
The last (and optional) step is to add a Gaussian Blur to the reflected image. In realism, the reflection will never be perfectly clear. While you may like it, and keep it, I like to throw it off just a bit -- so I'll ad the most slight blur.
You're done. Here's the finished blue version, the finished black version, and I even eliminated the background all together in this finished solid white version!
Take a different approach
Now, lets try an alternative, borrowing from Apple. Notice how their gradation is actually radial, and is offset to the lower left corner. Well simulate that by switching our gradient to radial. (Radial Gradient Diagram)
Notice in the diagram above, I've placed a solid black layer behind that gradient. You can lighten or darken your gradient by simply changing the transparency of the gradient layer with a solid black layer behind it. Make the highlight hot spot as intense or subtle as you wish.
... working with oblique reflections
Okay, one last scenario. What if the image you wish to show is not perfectly parallel to the camera, and presents a perspective view? All the other steps are exactly the same, except when you mirror your floated copy, you'll need to use the Shear Transform tool to pull it into a true mirror.
I followed the same steps as before:
* Duplicate the cut-out object using the float command (Ctrl/J or Cmd/J)
* Move Tool, drag the top, center handle down below to reflect the object
However, that leaves me with opposing angles.
So, with the reflected object active, use the Move tool (Tap V) and then
Choose Edit > Transform > Skew
Hover the tool to the side of the object to be moved, and the double arrows tell you it's ready to move. Grab the edge, Click and drag (usually using the shift key to constrain the movement) until it comforms to it's real edge.
These are the steps the reader in the Photoshop 911 Forums will have to use in order to make his photo look realistic. Each of the two sides will have to be skewed independently to comply with the bottom edges of the object. They'll each need to be skewed slightly more on their back edges to simulate perspective, and they'll each need their own gradient mask to provide the fall-off.
Now the image is a true reflection and you can finish everything as before
You're done.
Here's the finished piece.
There are lots of other variations, and some shortcuts we didn't mention, but this is the non-complicated series of steps that will work in all versions of Photoshop since version 5.5, and in all versions of Photoshop Elements. We like to keep it simple for'ya!
