Smoke Art

February 1, 2008

After looking at some pretty cool smoke art in the Flickr group called Smoke Art and here at the Sensitve Light website, I wanted to give it a try. There is a pretty useful tutorial on how to create your own smoke art here at Graham Jeffery’s weblog.

 Smoke Art

This was my first attempt at creating smoke art. I used my 5×7 collapsible black backdrop. I put an incense on a stool about 2-3 feet away from the backdrop. My Speedlite 430ex was then setup on a light stand about 1-2 ft away from the stool on the left side. My camera was on a tripod in the front ranging from about 1-3 ft away. I used my prime 50mm f1.8 lens. My camera settings were at ISO 200, f14, and at 1/200. It was done in my room with the lights completely turned off so that it would be completely dark. Of course this also meant I could not see anything so I just kept firing away hoping for some good shots. Afterwards, the room was really smokey and smelly. The flash was set to full power since you are suppose to have as much as light as possible to capture the smoke. I used the Cactus V2 to trigger the flash. I also snapped away so much, I overheated my Speedlite 430ex! I highly recommend listening to the recommendation of letting the flash rest for 10 minutes after continuously shooting 20 shots. That sort of sucks because I now have to send it back to Canon for repair and will be without my flash for a couple weeks. I definitely learned a lot from setting up this shoot and there are several things I will try to change next time to get a better shot. Some things would be to try to move the background back a little more or to add a snoot to the flash so that there is less stray light. Next time, I will probably try to use continuous lighting so that I can actually see the smoke and shoot at a higher shutter speed.

Cactus V2 Review

December 31, 2007

This is a review of the Cactus V2 Remote Triggers from GadgetInfinity.com.

t 16766 01 Cactus V2 Review 

If you are in the market for a wireless remote trigger for your camera, I am sure you have heard about the Pocket Wizard as the defacto tool that every professional photographer usually uses. You have probably heard of the cheap Ebay triggers as well since they cost a lot less and work almost the same. The Cactus V2 is another alternative similar to the Ebay triggers but is sold through a website called GadgetInfinity. This version resolves some of the incompatibilities that version 1 had with certain flash units. I have tried the V1 version Ebay triggers with my Canon Speedlite 430EX and it definitely does not work. The Cactus V2 works a lot better than the V1 with the Canon 430EX but it still has misfires every so often. They also tend to happen when you are setting up so it gets quite annoying. Once you start shooting, however they work a lot better. If you set up multiple lights and the lights will not get triggered 100% everytime but its not too bad.

The standard set comes with one receiver and one trigger and there are four channels that you can set them to. The trigger is mounted on the hot shoe of your camera where the external flash is usually mounted. The receiver can be be used with the external flash or any other light unit either with a PC cord or hot shoe. I have tried the receivers on a Canon 430EX, 580EX and Alien Bee lights as well and it seems to work fine. The set of one trigger and one receiver from GadgetInfinity is currently $32.95 and additional receviers cost either $16.95 or $19.95 depending on which version you get as the older V2 Receiver works fine with Canon Speedlites 580EX and 430EX but the newer version is compatible with more flash units. The V2 set comes with the newer V2 receiver. If you are shooting for money, then they might not be the best solution but for the typical hobbyist, they are a good deal. You can read more about the V2 and purchase it here.
