Choosing a flash

December 12th, 2011 No comments

I’ve been pondering what flashes to buy to use with my PW Flex/Mini system of wireless triggers.

Above all else, I want a flash with low RF interference with the PocketWizards TT5 system. Cost is the other quality. Prefer not to spend 580EX II money. HighSpeed Sync is the other requirement as I ‘d like to be able to shoot in bright daylight. Manual zoom head would also be nice. Read more…

Stabilizing AVCHD video with virtualdub

December 11th, 2011 No comments

Step by step writeup here.

My adapted method. Install the Matrox DVCPRO codecs from here.

Download Prism Video Converter

Using Prism, convert the highdef footage to the Matrox DVCPRO HD (dhv1) codec.

iIn VirtualDub, open up the new file, and stabilize using Deshaker, and re-save using Matrox MPEG-2 I-frame HD (m701)

Open up the video in Vegas and edit it.

AF assistant v3.1

December 4th, 2011 7 comments

UPDATE: Work has indeed started on the (near) IR version of this tool. Details on the AF Assistant IR 1.0 (in early development stages) can be found here.

Right from the get go, i wasn’t the happiest with the v3.0 design (see v3.0 link for details of why I built this, and previous version history) of the AF assistant. The main concern i had with it was the sloppiness of the case, and the extra cables that were required (which some of you commented about on the hack-a-day post).
So I did some searching around at local electronics shops and came across a small case that has a battery compartment for one AA battery. Digikey also sells a version of the case in black, which I will grab for the next upgrade. Much sleeker then cream colored on a black camera, though more expensive then the $0.25 I paid for the cream colored cases.

About the same time, i received an order from DealExtreme for some line lasers i had ordered some time ago. So I put together a circuit based on the v3.0 design (plugs in the side of the camera in the remote trigger port) and i have added a dc-dc boost voltage regulator that takes any voltage (0.7volts and higher) and turns it into a constant 3.3volts (based on suggestions from the hack-a-day post comments). This is perfect since that means that regardless of what battery i use, (1.5v alkaline or 1.2v NiMH rechargeable battery) i can get a constant voltage to drive the line laser. Read more…
