7 Day Shop 135 LED Video Light
So to answer the most relevant question first - Is it worth its price (currently £33.99 incl delivery in the UK)?
Short answer - Yes
It has several features which make it worthwhile, and even without those it would still be a decent buy for that price.
You can vary the amount of light output by use of 2 switches on the back of the light. This means it is not infinitely variable but has a decent number of 'steps' (12) so I didn't find this to be an issue.
It has 2 powering options - 6AA batteries OR 2 Canon NB-3L
There is a mounting plate for these included and you can actually insert this while the light is loaded with AA batteries, which means you can have a 'spare' power source ready to go at all times in the light.
There is a switch on the back of the light which allows you to select which batteries to use as well as giving access to the lights internal charging option. This is the best part for me, the light is also a charger which can connect via its mini USB port to any USB charge/Hub/Computer you have handy. So you can charge with a simple USB cable and not worry about using another 'wall wart adapter'. This was particularly relevant when I was in Japan as I wouldn't have wanted to fit another charger and power supply into my bag. On top of that if you need to remove the batteries to charge them there is a much higher probability they will not be put back in leaving you on a shoot with not batteries.
On each edge there is a mounting point which allows these lights, (and also the smaller version of this light) to be joined together to form a panel with as many lights as you need. The connector also mounts onto the shoe mount found on most DSLRs & video cameras, on the underside of the connector is a hole which allows the light to be screwed onto any standard tripod or Gorilla Pod (which is where this light spent much of its time!).
The light emitted is at 5500k which is in the right range for sunlight and daylight balanced fluorescent bulbs. This one of the few areas for improvement I can see. Light is not always at this colour temperature, (although I favour having a cool light if I have to choose) it would be a great if there was some provision for colour gels to be mounted in front of the light. That way the lights colour temperature could be modified for any situation quickly and easily. It is still possible to tape a gel to the front but it is always less fuss to be able to just drop one into a simple slot on the front.
Finally here is the video review with some sample time-lapse footage at the end and underneath a night test in my garden -

LomoKino un-boxing
YakTrax Pro - Snow grips for shoes
As an aside 2 years ago we were leaving her parents house after dinner and a man (a inebriated man with a very smelly kebab) fell over on the ice next to our car. We went to see if he was okay but he couldn't get up, turns out he broke the bones in his shin/ankle so bad the pierced the skin leaving his foot wobbling about at the end of his leg.
Now he may have been drunk but it doesn't take much to fall over and I was shocked at how thoroughly snapped his leg was.
On that pleasant anecdote I give you the Yaktrax Pro!
These strap onto your shoes and apparently increase traction on ice and compacted snow dramatically. The 'Pro' version seen here adds a strap across the toe of you shoes and is about £4 or £5 more expensive than the standard YackTrax.
Now there are many different makes of snow grips for shoes, most opt for metal studs/spikes.
The Yaktrax are a bit different as the have a system of clever metal coils which bite into the ice/snow and give grip in all directions.
Crucially they are reported to be fairly easy to walk on when surfaces happen to be free of ice/snow. This is great as the pavements can be very variable and also when going shopping taking them on and off every 5 minutes would could get tedious, most spike/stud based systems leaving you rocking around on ice free surfaces.
Unfortunately we have no snow or ice to test them out but I will post an update when the conditions allow for testing.
P.S. we called an ambulance, wrapped some blankets around him and kept him conscious till they arrived so all was ok in the end...

LomoKino - Analogue 35mm 'movie' camera
Very curious about this, it is a crank driven movie camera that accepts normal 35mm films!
There will be a full review and test footage when it arrives... hopefully soon....

Zippo Hand Warmer - Review by Tastes Like Tech
In the past I have tried re-usable gel packs that can be obtained at most hiking/camping shops. These do work but have a couple of annoying drawbacks, firstly they don't last very long and secondly they are a bit of a fiddle to 'recharge'. The process involves boiling in pans of water whilst taking care to keep them off the bottom of the pan, which may not seem so bad but I never seem to have one ready when I need it.
Step in the Zippo Hand Warmer! It is powered by lighter fuel and on a full 'tank' it will stay warm for up to 12 hours!!! On top of that it will keep a pretty much constant temperature during that time, (not rapidly heating up and then after 40mins rapidly cooling down like the gel packs).
I must admit the idea of carrying burning lighter fuel in my pocket sounded mad at first, but over the past few weeks I have used it at various outdoor gigs and not burned to death!
As it is made by Zippo I think we can assume it doesn't have a track recorded of dooming its owners to a fiery demise - they wouldn't be selling them if this were the case.
It is easy enough to use.
Filling it takes moments.
Fairly stylish in its simple construction (though picks up finger prints like a cop in CSI Miami... YEAAAAAAHHHHHH)
Long run time and you could carry more fuel if you are camping etc.

Graffiti Time-Lapse
Setup everything very carefully as always to avoid flickering. So I couldn't work out where the flickering in some shots came from! Turns out the sun shining on cars driving past the window caused the light shifts and therefore flicker....
The Salon is called Ko and it is on Suffolk Road in Cheltenham.

Canon Powershot A480 Infrared Mod Review
During a family get together recently my wife's uncle, (a professional photographer) showed me a modified micro 4/3rds camera. I believe it was a Panasonic DMC GF3.
Turns out that leaves, grass etc. turn a vivd white in IR (infra-red) photos and clouds become very well defined as the sky looks somewhat darker. People are also affected eyes look a little 'ghostly' and clothes/hair can take on a different tone.
I really wanted to try out an IR modded camera on a timelapse shoot, after scouring ebay I found a seller who mods them himself - infraready
He was extremely helpful and rushed out a Canon Powershot A480 which arrived just in time for my Japan trip.
The A480 came out in 2009 so its a couple of years old and was never the best camera around, but it is cheap and for the purposes of modding with a view to making some IR time-lapses it was fine.
It has a 10mp sensor and shooting at the highest resolution is more than sufficient for even 1080p HD video.
On most digital cameras there is a permanent filter in place which blocks light in the infrared spectrum. On these modded cameras the filters are removed.
It was my intention to install the CHDK firmware hack which would enable time-lapse shooting. There was precious little time to attempt this before I left for Japan and although I installed the firmware successfully I could not get the time-lapse scripts working.
This scuppered my plans of shooting infrared time-lapses until I came up with the idea of using a clamp to hold the shutter button down in continuous shooting mode.
This gave me no control over the interval but it was quick and it worked!
I'm sure I'll get all the firmware working now I'm but I just didn't have time to spends playing with settings etc. whilst in Japan with lots of other things to do.
On some of the shots in the video below I ran the camera with the CHDK hack active for control of focus and some other parameters. In the last shot I used the camera with standard firmware.

So what was I doing in Japan?!
This year alongside my playing I though that it would be fun to do a big timelapse project so I lugged about 30KG of photographic equipment to Japan along with me, the mac and my guitar.
This included a few pieces of equipment I had for review - some video lights, white balance cards, audio recorder etc. (those should be coming out very soon...)
So when I wasn't playing gigs with Japanese metal, pop punk bands....
...and chilling with fans
:o
I was sitting or standing for hours listening to a camera shutter fire every few seconds, perhaps with the added twist of the motorised dolly moving.
Youtube Collaborations with Hanafubuki / Yokomaririn
On previous visits to Japan I have been fortunate enough to meet them and I have been mentioned in a few videos which you can view below.
This year we actually set out to make a collaboration video which is still being edited but is nearing completion...
it was a fun shoot around Umeda in Osaka despite some heavy rain forcing changes to planned locations.
Later in the trip I visited Kyoto and we spontaneously met up when I was out shooting more time-lapses around the city. Ate some great Tempura and Noodles, after which I actually got to feature in a 'Snack time' video featured on the Yokomaririn Channel
I look tired and slightly scruffy as I had only planned to be behind the camera that day!
Here are more videos from Yoko sans channels which feature me in some way ; )
Meeting Youtubers at the Lomography Store in Tokyo!
First up Minjonju
We share an interest in cameras and photography though my knowledge and skill pales in comparison to his!
I have actually featured in a couple of his videos before which you can view below, I owe him a big thanks for helping set up my gig at the Tokyo Lomography Store in Harajuku.
It was a very enjoyable gig surrounded by all the Lomo finery and I also got to meet Japanese techblogging legend Jetdaisuke!
Bristol Balloon Fiesta 2011
I had enquired before hand about getting access to the press/media area in order to get better shots as the spectators are not allowed in the arena where all the balloons inflate. Unfortunately they had filled the quota etc. for the event..... not to be discourage I got up bright and early for one of the 6am launches arriving on site before 5am.
Through the use of Jedi mind tricks and an ability of being able to act like I'm meant to be 'backstage' gleaned from countless concerts/festivals etc. I managed to get into the arena and capture the following timelapses with the use of various cameras, lenses and a Kessler Crane PB Dolly.
The weather was not ideal for the launch, also the clouds were 'boring' from a timelapse point of view for most of the morning.
The following day I returned with my family and shot this sequence from a hill at the side of the arena that I had scoped out the previous day.

Just Arrived! Little Bramper
Little Bramper - Bulb Ramping intervalometer, a set on Flickr.
I have just received a Little Bramper!
This little device acts as a timelapse timer/intervalometer.
But thats not the good part, it allows you to smoothly vary the exposure time. This means you can get amazing Sunrise/Sunset time-lapses.
It is available in limited runs here http://www.thewhippersnapper.com/LittleBramper/Site/Home.html

Some examples - Orestor f2.8 135mm
Orestor f2.8 135mm - Meyer Optik Gorlitz, a set on Flickr.
Here are some tests shots I made this afternoon.
The two shots of the bird feeder are interesting, one is wide open and has a very shallow depth of field. The other was stopped down and you can see more detail in the out of focus areas.
I also tried photographing my son, a fast moving target. Found that I had to stop down as it was very difficult to alter focus fast enough and keep him framed given the focal length this lens is giving me on the 550D.
But once I got used to it I managed to get some really nice shots that were plenty sharp and in focus where they needed to be.
Orestor f2.8 135mm - Meyer Optik Gorlitz
The M42 screw to Canon EF mount adaptor finally arrived!
Been testing it out and getting used to the 135mm focal range + the 1.6 crop the 550D is adding.
From what I have seen so far I think I am really going to enjoy this lens!
The focus ring does almost a complete turn to get to infinity, which given how shallow the Dof can be seems essential….
test shots and videos to follow soon

Meyer Optik Görlitz - Orestor 135mm f2.8
I will be doing some reviews and info videos about this and other older lenses.
Just waiting for the M42 screw to Canon EOS adaptor....
Its in really good condition and wasn't too over priced, this lens has become very popular lately so the can go for a silly amount.
The 15 blade aperture is very smooth and has no hard stops, can't wait to test it!

FAQ NO. 6 - Colour Correction / Grading in my videos
Colour correction was done with Magic Bullet Looks, it's a great plugin and is surprisingly easy to use.
The only downside would be that it is fairly expensive if you are misting editing videos for fun!

Filmic Pro App Review
Very easy to use, the exposure and focus points can be dragged around the screen making it easy to select thee area you want to take your locked settings from.
The fact this app also allows you to control the frame rate going down increments of 1 from 30fps is great if you are looking to match footage from several cameras to the iPhone.
Currently on the UK app store for £1-79 and worth every penny!
I will post some outdoor test footage soon....

The photos are available at the original resolution on flickr if you wanted to look in more detail.
All photos were taken with these settings
iso 100
shutter speed 1/50
f14
Only the focal length was varied.
I aimed to keep focus on Art-bear-funkel (the bear... thats his name)
