Trix Flash Modifier


———Straight Flash ——————With Trix Modifier—-

Over the years I’ve purchased many different flash modifiers. I have a whole collection of them from Lumiquest and Gary Fong. There are some basic problems I find with most of the ones on the market:
#1 They don’t make the light sources big enough. The size of the source is what changes the quality of the light.
#2 They don’t compact nicely to fit in a camera case.
#3 They block the focus assist light and IR trigger.
#4 They cut down the efficiently of the light too much.
#5 They fall off the camera.

I’m off to Alabama next week for a couple of days of run and gun annual report shooting. I’m taking a kit of three Canon 580EX II flashes with stands, several breakfast cereal bags, rubber bands, and straws. You see, my current flash light modifier of choice is very low tech. I call it the Trix Light Modifier because the first one was made from a box of Trix cereal. I simply rubber-band the cereal bag onto flash and blow it up with the straw. It’s not pretty, but it makes a real nice light source. It’s not about the money, it’s about the functionality; there just isn’t anything on the market that works as well.

As you see in the picture above, the Trix modifier makes a good size light source, it doesn’t cut down the light too much, it’s very portable, it doesn’t block the focus assist, and it doesn’t fall off. I find it to be very flexible; the bag can be shaped in a number of ways and it will retain it’s form. It even pads the camera from being bumped around. It’s like a little camera air bag.
I also carry some very small clamps and paper thats black on the back and white on the front. These are used to gobo or flag the light from coming back into the lens.
It doesn’t look cool, but Ansel wouldn’t care about that and I don’t either!

Cfast to Replace CompactFlash

The Compact Flash Association announced the development of a new memory technology which will be ready for integration by camera manufacturers in 18-24 months. Starting in late 2009, high end cameras will likely use Cfast memory. The new standard will not be backward compatible with CompactFlash, so an entirely new system will be necessary: camera, card, and card readers.

Cfast overcomes the interface bottleneck by utilizing a serial ATA interface. Interface transfer speeds will be boosted from 45MB/sec to 375MB/sec. Camera manufacturers may be able to do away with bufferers which cache images that are shot in quick succession; thus allowing for continues firing.

Read transfer rates will be significantly improves which is a welcome advantage to photographers downloading gigabytes of images after each shoot. New card readers will need to be developed for the standard as well. I would welcome a S-ATA cardreader with 4 slots!

An interface boost from 45MB/sec to 375MB/sec opens up many new possibilities for camera manufacturers. It will be very interesting to see how camera designs utilize this speed. I hope to see built in exposure bracketed burst and HDR features work their way into camera bodies.
