Last night it was a talk on 3D photography by Colin Bright from Buckingham. Colin does 3D photography for a hobby using two cameras and said it is quite good fun to bring out family 3D shots to make an interesting display rather than the normal holiday snaps.
We were all give 3D glasses (eg the red and green cardboard ones) to keep.
But first Colin talked about the history of 3D and the Victorians took a great interest in it with various gadgets invented to show two pictures blended together in a box to give a 3D effect.
Then machines showing ‘what the butler saw’ became a fixture on sea front piers.
Then television took audiences away from cinemas so 3D films came out to tempt people back. Television soon came out with 3D but the wearing of glasses to watch it did not prove popular and it has faded.
Colin then described the science behind it and how it is still used in space to gather information on the planets terrain.
Then Colin showed us how to take and produce 3D pictures using two cameras which work like our own two eyes. Our eyes are set a small distance apart and send signals to our brain to produce the image we see. Colin explained early caveman needed to survive and was not too bothered about danger in the far distance but needed to see and be aware of the vicious animals like the sabre tooth tiger which might leap from the rocks close by. So we have a 3D effect in our sight near to us but in the distance looks fairly flat. This happens in 3D pictures taken.
Colin had a cat that has now recently past away and he added a picture of the cat into Photoshop and took out the background. He then layered in a new background, creating a second picture from it and moved the cat just 5 pixels to the left on the same background. The software removes red and green creating the the 3D lines around the cat.
The two photographs are blended together to give the 3D effect.
Soon it was coffee time
In the second half we were treated to a series of 3D photographs
So we could sit back and see the show lol. I have made the pictures bigger so if you have 3D glasses you can have another look. For those that don’t you might have to rustle down the quality street tin for red and green wrappers lol
This was an outstanding one with the sign post coming out of the screen but not sure its give such a good effect on here. The brain does take a while to adjust so give them a minute to see if they work.
Buying a new car for his daughter this one she did not get lol. This image does work for me with the glasses on
This was certainly better on screen last night
On this one you can see both turrets sticking out
This cockpit certainly is a good 3D image
a jeep that stands out
Another good one on screen last night
And the type of images used by NASA
And finally one of some of last night’s audience or are they cardboard cut outs lol
Thank you to Colin for doing the talk
Next week is
There has been a murder and I believe we may need to bring our cameras along but more on that later
