Trying 1970s Beam Splitter On Panasonic Lumix G3 [3D]

Tuesday, March 6th, 2012

I got hold of an old Pentax 3D stereoscopic beam splitter manufactured in the late 1970s and thought “Why not try it on my digital camera?”. So here we are! The splitter effectively turns the lens into a 3D lens, giving 2 views of the same scene side-by-side, from a slightly different perspective (shifted sideways).

I had considered using it while recording laser shows in the future, but because of the wide separation, and highly zoomed view required for it to work, that would probably just result in headaches when viewing it. Plus, the view is tall and narrow, which is not ideal for laser shows, where the beams tend to stay above eye level. Oh well, it’s still fun to play around with.

Random Macro Clips

Thursday, March 1st, 2012

I got a cheap macro lens filter and took some videos of close-ups. Lens is 20mm (35mm equiv: 40mm) at F1.7 for a ridiculously shallow depth of field (only a tiny part, distance-wise, is in focus). I cropped the 1920×1080 video (instead of scaling it) so that detail isn’t wasted when viewing at 720p. The camera is a Panasonic Lumix G3.

Night-time Driving

Monday, February 27th, 2012

I got a new lens for my Lumix G3 camera. Its aperture can open as far as F1.7, so I wanted to try it out in the dark. However, driving was a stupid idea as the lens doesn’t have optical image stabilisation to reduce the shaking thanks to the well-maintained British roads. I tried to reduce shaking a bit in software afterwards, but it’s more distracting than helpful (I should build some kind of stabilising rig). After 02:45, there’s no software shake reduction. I was focussing manually throughout the video, which isn’t easy at F1.7 as the depth of field is so shallow.

Colours are also corrected in editing. At 00:39, I attached a UV filter, which unintentionally added lots of flares from bright lights. I thought they looked nice at the time, but I got annoyed with them after re-watching the video for the 5th time.

My brother was driving, playing some music of his. You can find the music he’s made here. This particular track is “Remember This“.

Lumix G3 sustained burst speed (this video is not useful to anyone)

Saturday, February 25th, 2012

3232×1824 (6MP) at ~4 photos per second with a class-10 SDXC card. At this speed, this is the highest resolution at which it can take photos non-stop. 4592×3448 (16MP) at 4 photos per second is possible, too, but the cache fills up after about 6-10 photos and then the speed drops massively.

With a higher shutter speed and lower ISO (yes, it seems it does some processing to reduce noise), the burst speed would be ever so slightly higher (although the cache will probably fill up). On a bright day, maybe I’ll repeat the test with some different settings.

By the way, this video is not useful to anyone.
