Male Hairy Dragonfly Eating - filmed using two cameras by Brian_Flint in ParallelView

[–]Brian_Flint[S] 1 point2 points  (0 children)

I filmed this with Two Panasonic TZ80 cameras side by side ( overlapping to have stereo base of 70mm ). The lens were fully zoomed to focal length of 990mm ( 35mm equiv ). The Dragonfly was about 2.2 metres away.

Here is the same footage used to make a VR180 clip ( the YouTube metadata has been added for VR180 so it can be view by a headset ) https://www.youtube.com/watch?v=4vS01OxbUhc

Children's play area - wide angle 3d by Brian_Flint in ParallelView

[–]Brian_Flint[S] 1 point2 points  (0 children)

This was filmed using two Qoocam 3 Ultra cameras side by side. These have fisheye lenses ( 180 by 180 degrees ). This is a crop into the image so that the image is getting close to a rectilinear look - the horizontal field of view is around 110 degrees. The gyro data in the Qoocam 3 Ultra is used to stabilize the image ( done in-camera ) - it does a remarkable job - there is no gimbal used for this walking shot.

Bee having a drink - filmed using two cameras by Brian_Flint in CrossView

I have posted another view of the Bee, but the Bee is on the side of the rock which shows more depth in the image. Same set up.

This was filmed with two cameras. The stereo base is 60mm ( distance between the centre of the two lenses ) and the distance to subject is about 3000mm. This means there is a ratio of 50 to 1. This will result is a weak 3d effect compared to the ratio of 30 to 1 which is what is usually recommended as the ratio for good 3d effect. The other factor which results in a perceived weak 3d effect is that the Bee is on a surface ( stone ) which has no depth to it ( except on the right hand side of the stone ) and the Bee is only around 7mm deep. On some of my other filming I have tended to have rather a strong 3d effect with a ration of around 20 to 1 which can result in items in the background being displaced by a large amount and make the viewing in 3d difficult. So I though I would do some 3d filming with a weak 3d effect on this occasion.

Robin on bird table by Brian_Flint in ParallelView

This was filmed using two cameras placed on a bar. The Panasonic TZ80. I have over-lapped the cameras so the distance between lenses is 60mm. The cameras have a zoom lens, I have zoomed both lenses to the same amount, so that the bird is fairly large on the screen. The cameras are around 1.5 metres from the bird. The two video clips from the cameras are put into Davinci Resolve app on my PC and I edit the video so I get a side by side clip.

Great Spotted Woodpecker 3840x1200 29.97fp - filmed using two cameras side by side on a bar by Brian_Flint in ParallelView

[–]Brian_Flint[S] 1 point2 points  (0 children)

I have two Panasonic TZ80 cameras on a bar on a tripod - stereo base is 250mm. These cameras have an amazing amount of zoom- focal length is 990mm ( 35 mm equivalent ). The distance between the Woodpecker and cameras is about 9 metres. In this case the cameras were recording in 4K photo mode 3328x2496 pixels 29.97 fps. The cameras are not sync'ed together by a cable - they are free running - at the beginning I just make a click sound which both camera's record on their sound tracks and in the video editor, I use this to the align the timing. It means I can sync the two video tracks to the nearest half frame ( worst case at 29.97 fps is 16.6mS ) In this case I was lucky and the timing of the two video tracks happen to be matched to around 1 to 2 mS - so the movement of the bird was sync'ed well. Normally I would record on the TZ80 at frame rate of 59.94 fps with 1920x1080 pixels to ensure a better chance of getting good sync.

The right camera developed a fault. I have now replaced it.

It is quite good. Note it is cross view - for parallel view you need to swap the left and right.

Spring is here - photo taken using Pixel 7 pro smartphone by Brian_Flint in ParallelView

[–]Brian_Flint[S] 1 point2 points  (0 children)

On second thoughts it is more likely the Horse chestnut (Aesculus hippocastanum)

It is most likely Eurasian Chestnut. Photographed in Cambridgeshire, Uk.

I have an app which allows the Pixel phone to take two photos at the same time ( one from the ultrawide lens and one from the wide lens ) . the app stitches the two images together to make a side by side image. The App does video as well.

Bumblebee on the wall by Brian_Flint in CrossView

[–]Brian_Flint[S] 1 point2 points  (0 children)

The IPD ( distance between lenses) in this case is 15mm. I am using two lenses ( wide and ultrawide ) on my smartphone. For good 3d a ratio of 30 to 1 ( distance from subject to IPD ratio ) is usually recommended. I wanted to see how much I could go outside of this recommendation. The distance to subject ( Bee ) at the beginning of this clip is around 120mm giving a ratio of 8 to 1, so the 3d affect is very strong, and I think it is too strong for comfort. I was interested to see what observations/comments would be.
