Graeme Davidson: Thank you bibilo57 and jmgir!

Jmgir, I've looked into the reflection some more but canot replicate what you are seeing. If I take a foot square mirror, place it horizontal about a foot in front of me and hold a phone a foot above it in the same orientation as the craft, I see the underside of the phone and it's pointing into the picture like I have on the entry.

If you would like me to, I can temporarily put an image in my gallery that shows it as you describe but it looks wrong to me. Let me know if you'd like to see it done that way - I'm happy to oblige!

Jmgir; I decided to redraw the reflection. You can see it at

The back of the craft's diamond now points down out of the frame and I've added a water effect. It's still not that realistic though, but that's my fault :o)

Jmgir - one thing I have definitely got wrong... the diamond shape the engines are on should certainly be angled down to point out of the frame but the pointed end of the craft stil points into the picture. I tried to correct the reflection but it needs a complete redraw since a simple inversion makes the pointed end of the craft point out of the picture.

Reflections are tricky things!

I set up a paper aeroplane over a mirror to replicate the angles in the picture but still the reflection points into the picture.

I took a snapshot of the setup and uploaded to the galleries at

http://www.dpreview.com/galleries/7368037848/photos/1436703/perspective-check

It must be one of my worst photos ever published :o)

It shows how the reflection looks and it does still point into the picture. As I mentioned in an earlier post, once objects get any distance above the reflecting surface the reflections are actually a completely different view of the craft - the underside from an angle - and not a true inversion.

All the best,

Graeme

Thank you Jorge!

When this image was created a while back, the reflection came into debate on another forum. You can see an example of the refection inverted on that forum but that didn't look quite right either!

You can see the thread at http://www.talkgraphics.com/showthread.php?49722-Futuristic-collage&highlight=

Let me know if the inverted version on that thread looks more natural.

As a thought experiment - if the UFO were to be substituted by a bridge, would the reflection point out of the frame? I think the UFO reflection is a complex issue in that it is not an inverson that is required but a complete redraw of the object as seen from a different angle dictated by the viewer position and height of the craft above the water. I definitely fudged an approximation on this drawing though :o)
