I want to make a reflection of a product image in Photoshop. The product has been shot at an isometric angle – in Photoshop there is only ‘flip horizontally’ or ‘flip vertically’ so how can i match the reflection angle to the product angle?

Thanks.

All you have to keep in mind is that Photoshop can’t "invent" the underside of an object—say, the chassis of a car, for example. Also remember that you have to watch any perspective distortion. If it doesn’t look right to your discriminating eye, chances are it’ll look a bit "off" to casual observers, too—even if they can’t really explain why—and will come across as amateurish.

As long as the object you want to reflect is photographed pretty close to straight on—meaning not from a high or low angle—you should be able to fudge it.

Will,

please show scanned pencil drawings:
a) the original image,
b) the expected reflected image.

About the ‘isometric angle’:
Viewing a cube along its main diagonal
can be considered as ‘viewing at an iso-
metric angle’, but a REAL camera doesn’t
produce an isometric perspective (which
would reproduce originally parallel edges
as parallels in the image).

Well for example take your cube on page 16 – how do you create a reflection for that?

G’day Will

When you transform an object (Ctrl T) if you right ‘click’ inside the transform box you get more options, such as skew. You can drag the points to various angles which might help and you can still choose another option by again right ‘clicking’ within the transform box.

As Phos pointed out it all depends on whether or not the true reflection would have shown things not in the original shoot. Can you post a pic? or would you have access to the product so you can realistically envision it?

regards

Will,

do you mean a reflection as if the cube were
placed on glass or in water ?
In this case, knowledge about hidden parts is
not required.
For me – I’m not really a Photoshop expert –
it would be a matter of cloning.
I would inspect some photos of similar scenes
and then try to create the reflection arti-
ficially.
Perhaps Filter > Vanishing Point is helpful.
Now I’m thinking that your object has vanishing
points (could be expected for a real camera
shot).
