New batch of high-speed flash units for early 2016 – light pulse duration 25-microseconds, light pulse energy 100 Joules.

Further to my earlier post below, I have upgraded the spec as I will be using a different capacitor for these custom units.

The spec now reads:

  1.  Light output power 100 Joules.
  2. Light pulse duration 25-microseconds (1/40,000th of a second).
  3. Recharge time less than 5-seconds.

The units are powered by a 12 Volt battery pack which is supplied with a charger and the flash unit.  Estimated cost of flash unit, battery pack and charger is £2,000 plus VAT at 20% plus p&p.

Let me know if you have any interest in this type of equipment.

New batch of high-speed flash units due early 2016

In order to keep my hand in the HSF world, I will be making a batch of high-speed flash units that will be available early 2016.

Talking to a number of professional users I have decided that the specification for the new batch of units will be:

  1.  Light output power 75 Joules.
  2. Light pulse duration 25-microseconds (1/40,000th of a second).
  • Recharge time less than 5 seconds.

The units will be powered by a 12V dry battery pack (supplied with charger unit).  Estimated cost of a flash unit, battery pack and charger is £2,000 plus VAT at 20%, plus p&p.

Let me know if you have an interest in this equipment.

High-speed flash photography rig resurrected

As the weather simply refuses to play ball regarding the deep-sky imaging work, I have decided to resurrect the high-speed flash rig for water drop collision photography.

Going to try a couple of new things as well as following old recipes.  Will see if I can get a three drop collision worked out (I know this is not a trivial exercise) and I will see what 3-D (stereo) photography of the water drop collisions produces.

My feeling is that unless you have some other objects in the scene to create some depth, the water drop collisions won’t appear much more 3-D than they already do.  Experimentation time 🙂


Learn something new every day! High-speed flash lesson for today.

A couple of days ago I did some more  high speed flash work with the 9-microsecond Ultra units.  Here is the result of a double egg explosion.  At first sight it looks o.k. but the more you look at it the more you realise that it is blurry around the edges!  What’s going on here?  I know the flashes are fine as I did all that water drop work just a few weeks back.  I know that it is some sort of distortion as I can take the image into Photoshop, undistort it, and the image sharpens up a LOT.  So what’s changed from the water drop work?  Well for this session I did use the Canon 50mm prime lens instead of the Canon 100mm macro lens I used for the water drops.  But the 50mm prime is one of Canon’s sharpest lenses AND I have used it very successfully for high speed flash work in the past.  So what exactly is going on here??  Two days floating around the subconscious and this morning the answer hits me.  Shooting eggs is a VERY messy business.  This time I was prepared!!  I covered all the gear in cling film and put a cheapo UV filter over the 50mm lens to protect it from the mess.  And there’s your answer.  Had no idea of the repercussions of looking after the lens.  The UV protection filter has introduced all that edge distortion.  Live and learn.  Still very annoying though to have spent all that time and effort on a duff imaging session!

Finally got there in the end :) Water drop collision, in a glass, under a bubble.

After a few days of trying this and that I finally got the shot I’ve been after.  Here we have a water drop collision, in a glass of water, under a bubble.  Canon 5D MkII camera with Canon 100mm macro lens and 3 x “Ultra” flash units from highspeedflash dot com.  You might think this looks pretty good – BUT – it has nothing on the fluke image I caught and have now submitted to the Sony World Photographic Awards “Split Second” section.  I can’t give the game away at this stage, but if you recall the shot water filled balloon image that went viral, then there is a big similarity with the image I sent in to Sony.  I’ll take a few more water drop collisions and then move on to shooting (literally) stuff again 🙂
