Radian from Alpine Labs

Programming the Radian motion time-lapse device from Alpine Labs

If you have not yet seen my first look review of the Radian and Michron from Alpine Labs check it out here

Radian is a move-shoot-move device which essentially means it takes a photo by triggering the camera moves and then repeats the process. The device is programmed with an Android or iOS device and communicates via the headphone socket (which I think is really cool).

One of the features which I particularly like is the ability to ‘ramp-up’ or vary the speed at which the motor spins during the time-lapse sequence.


The basic interface is clean and intuitive setting the angle to move through, the time taken and the interval for photos to be taken. The device can still be used without a DSLR and other cameras such as a GoPro can be mounted onto it.


The advanced options give the flexibility of delaying the start of the sequence and giving a ‘ramping’ option to both the speed and the exposure.



The motion can be ramped either with a linear setting (top photo) or a curved setting (bottom photo). This gives the opportunity to the start the movement at one speed and slow down for another part of the time lapse.

The easy of programming combined with the simplicity of the upload from an audio jack makes the Radian very simple to configure prior to a time lapse sequence.


Rotolight Sound and Light kit

Product review: Rotolight Sound and Light Kit

I recently bought the Rotolight Sound & Light kit whilst at the Gadgetshow live 2014. For around £150 you get both a lighting and microphone system which will complement any DSLR / Camcorder with hot-shoe and microphone input.

The kit comprises of:

* The Roto-mic shotgun microphone
* Dead kitten and foam windshield for the mic
* Carry case for the mic
* Additional rubber bands for the shock-mount
* Rotolight RL48-stand mount
* The Rotolight accessory pouch
* The Rotolight RL48 Ringlight system
* Filters for the Rotolight

The Roto-mic shotgun microphone

The specs of this little shotgun mic are very good. I am really pleased with the audio quality and have tested it under several different conditions. It is the perfect mic for interview recording in a crowded noisy environment when a Lavalier microphone is not appropriate or needed.

* Uni-directional, 40Hz - 20kHz
* Gain adjustment -10dB, 0dB, +10dB
* High pass filter (80Hz or Flat)
* Powered by internal 9V battery (up to 100 hour life)
* Shockmount
* Fits onto a Hot-Shoe
* 3.5mm mini-jack connection cable

The foam wind shield can easily be removed and replaced with a fluffy dead kitten which when tested on a windy afternoon reduced most of the noise. The design is very similar to other DSLR shotgun microphones and looks very professional mounted on top of a DSLR.

The Rotolight RL48

I was looking for an LED based lighting system and when I came across the combined light and sound kit I was confident that this was a product I was going to find very useful!

* Equivalent to 100w
* Continuous flicker-free light
* 140 degree beam angle
* Adjustable colour temperature (via filters)
* Dimmable (via filters)
* Powered by 3AA batteries for up to 4 hours use.

I was pleasantly surprised by the light levels provided by the light. The use of filters to adjust both the colour temperature and brightness is very simple and reduces any additional electronics or control buttons.

The light can be used in two positions, firstly in the photos above I have the microphone and light separated on an accessory bar. It is also possible to remove the inner ring from the light and place this over the microphone giving a combined light and sound kit. I was pleasantly surprised to discover that in this configuration the ring also blocks out unwanted sound from behind the camera.

Overall, I have been very pleased with this kit and think it will make a valuable contribution to my home and outside recording. It is a good price, with the combined kit costing less than comparable microphones.

The kit can be purchased from Amazon here:
