Cheapskate Tuesday 3: Trigger Happy

No not the Weird Al song (although that is awesome).  I refer of course to radio triggers. What is a radio trigger? Well, very simply this type of device transmits a signal which then tells a receiver unit to make a pulse of electricity, which fires either a flash or your camera. If the transmitter is mounted on your camera, the trigger will command receivers to fire flashes or other cameras mated to receivers with a trigger cable.

I have been using the Yongnuo YN-602 triggers, but many of the more modern ones use a transceiver design, with each unit being able to act as both a transmitter and a receiver. The YongNuo products are cheap, and a transmitter with two receivers is about 54 bucks. Other brands may be even less expensive.

How does this work in practice and what can it be used for? Well, this summer, while sitting in front of this Osprey nest in Port Moody, I had my camera set up on a tripod, with a 300 mm lens aimed and focused on the nest. Rather than stand by the tripod with my finger on the trigger, I mounted a receiver on the hotshoe and held the transmitter in my hand. This way I was free to move around and not jostle my camera while waiting for the very infrequent visits by the adult Ospreys. When an osprey was about to land, I would trigger the camera, which was set to high speed burst mode, and get some shots…Maybe not the most elegant shooting, but fun and relaxing.

This Bombus vosnesenskii, was taken with my 100 mm lens and Yongnuo triggers firing the two speedlights mounted to a special bracket on my camera (to be covered in an upcoming post). In this case, the trigger is being used for its most common purpose, namely to trigger flashes.

A sidelong portrait of the charming  Tailed Frog (also to be covered in an upcoming post) was also shot using the trigger to fire a flash, this time with a single speedlight with a Cheapskate Diffuser over the frog.

This unusual shot of a male Northern Flicker (Colaptes auratus) cleaning out the nest hole of baby poop was a bit more involved. It used two Yongnuo transmitters, one in my hand commanding a receiver attached to the “cable release” ( a 2.5 mm jack) to trigger the camera (as with the osprey shot), and the other transmitter on the hotshoe commanding a speedlight near the nest to fire.  This froze the bird in flight, and allows us to see what was going on.

These triggers can also be used for other things, such as triggering studio mains and other larger lights. Another useful trick is to combine them with Magic Lantern software to trigger recording of video on Canon DSLR’s. Probably the coolest usage would be to use them to trigger your camera in situations that would be impossible or too dangerous otherwise  such as near shy or dangerous animals. The range is about 100 m or so, so you will have lots of room!

These things are versatile and cheap, so get trigger happy!

Cheapskate Tuesday 1: cheap flash diffuser

Nabid at Burnaby Lake Park
the subject was illuminated with the cheapskate diffuser

Hi, and welcome to Cheapskate Tuesday! Here I will try to convey how I mess up my photos by cheaping out I save money by applying a DIY ethic to photography projects. I plan to explain as many of my tricks as I can, and then will scour around teh internets for cool looking budget-minded photo mods and tricks.

This week, another version the ever popular macro flash diffuser…There are endless varieties, but the whole purpose of them is to enlarge the size of the (small) light source relative to your (probably small) subject, improving the quality of light by filling in shadows and reducing specular highlights.

I will admit, this idea is not wholly my own. When I read this post by Piotr Naskrecki (one of the greatest close-up shooters around) and he mentioned using file folders to diffuse speedlights, I immediately went out to the dollar store to find some…I am not sure if I found the same ones, but here is what I riffed off of that:

This badboy you can build for roughly two dollars. So say you have your flash, and since you are budget minded it is a beat up Yongnuo 460-II (35 bucks used, baby)…

First things first…You have velcro around the flash head, right? If not, put some there… This will be important later. I like to use the soft side, because sometimes I cuddle up with my speedlights.

Next, you need to get a file folder such as this:

Look for yours at a dollar store, or budget office supply store. The key feature of this is that it has a white plastic interior…It is almost the thickness of paper, but it is a nice tough white plastic… I have no idea what the composition is, but the stuff is tough! It supposedly is imported by DTSC Imports in Burnaby BC, and made in China.

Next, tear away all the pink and transparent plastic, leaving two beautiful sheets of white plastic:

Next, fold one of the white sheets so that the two shorter sides meet midway…Give it a good crease.

Next, cut two flash-head-sized pieces of self adhesive velcro (the hook side this time!)

Stick those about where you might expect them to go:

And voilà!

Stick it to your flash head:

Make a few, throw em in your bag, and there you go.
I like this modifier in particular because it stores as flat as a sheet of paper. The plastic is so tough, you don’t have to worry about it tearing, and it won’t get dirty like fabric-covered softboxes. Also it costs 50 cents….

I made extensive use of this simple mod on my recent field excursion to French Guiana, and appreciated the simple stowing and quick deployment this device offered. Here are some examples of what it can do:

It works on Rhinella maragritifera (crapaud feuille) as well.

Try these diffusers on crickets!

This glass frog was a little challenging…

Jumping spiders are a good way to test any flash diffuser!

Note: you could probably use the pink translucent stuff to gel your flash for some really weird looks, or perhaps for other arts ‘n’ crafts.  The transparent stuff might make a good humidifying cover for an insect cage, or whatever else you might use transparent plastic for.  Good luck and good shooting!
