Just playing around with the diffuse glow filter before going to bed. Long day and unorigional i know but im tired and need rest.

It took all of about 10 minutes to convert a plastic pencil box into a nice flash diffuser. All I did was cut a hole in the box using a nibbler then taped some aluminum foil to the back side.
new diffuser project, polymorph mouldable plastic with concave inner diffusion sheet and 2 different sheets on outside [ bogan/manfrotto diffusion pack sheets - hampton frost inside and 253 &129 on outside ]
I call this a Semi-DIY project because the piece in the far upper left, which is somewhat complex, comes from a disassembled cheapo ringlight which I'd purchased for $38 but decided to return. Instead, I made a deal and simply got a $28 refund while keeping the item. So this plastic and velcro piece cost me $10. It works very nicely.
The funnel was cut to have four tabs with holes drilled in them (look closely) to match the four screw-holes in the attachment dingus. I used my own nuts and bolts and the two parts are very securely connected.
I sanded the inside of the funnel just to make sure the paint would stay put. One coat of some latex enamel. I cut a circle of small-bubble bubble wrap from a large sheet of the stuff I often use as diffusing material. Taped into place this alone does a nice job, as can be seen in photo #5.
But I wanted the final illuminated disk to be larger, and I wanted to make sure the light would be thoroughly and smoothly diffused, so I cut the flat inside panels out of three plastic bin covers. I bought a bunch of these shoe-box sized containers for $1 each to organize my stuff on bookshelves and with incredible foresight had saved all the covers. Three cut-out panels wrapped around the funnel and taped into place then trimmed to size added just enough extra diameter for me. The plastic is light and flexible - this whole unit will pack well and take a beating; it weighs the same as four AA batteries. The final diameter is 7.5 inches - between a softball and a volleyball.
Last step: I cut two circles of see-through fabric and taped them separately into place, taut and with the "grain" of the two pieces at right angles. In photo #6 the result is tested with a Nikon SB-600 speedlight. The SB-600 is set for maximum spread with the wide-angle flap down. I expected a nice circle of projected illumination but was surprised at just how smooth it was and how nice the edge fall-off looked.
This is a wide-angle device and would very likely get in the way of the shot if I tried to use it to illuminate just a part of the subject. From a few feet away it will illuminate the entire frame quite evenly. The nice fall-off on the edges gives me the ability to use this on half the frame to even out other lighting or get an effect. Though I'm not much of a portraitist I can see this being a nice unit for that purpose; it would make very nice reflected highlights in eyeballs. But this will really come into its own for macro and close-up work. Placed just outside the frame this will act like a huge softbox (costing $thousands) does with a human. It will be like half a light tent, but much easier to use and maneuver than either a real softbox or tent.
Note that there is a horizontal rectangular area of slightly more intense light in the center of the projection - matching the shape of the speedlight. It's subtle enough to not be a problem. Total cost (guesstimate) if you count only $10 for the manufactured part and include $1 for each of the three plastic covers: $15.
Diffused version: no harsh shadows, no hot spots on the lenses. I also cleaned up a seam on the upper-right corner. See the next photo in my stream for the harsher-light version.
An exercise in how quickly I could set up, light, capture, and take down. This all went off in about five minutes.

This material I got from the dollar store.. It's suppose to be for dusting, but didn't work worth a dam. The light is perfect, see my too~kan~>! flic.kr/p/9MAcbQ
Ok, this new version looks more like the pic did in camera. Thank you again PGMB! I just used picnic to fix this.

Im having issues getting the brightness, tone and tint correct between Flickr and Photoshop. Odd how different the pic is between the two programs when viewed on the same screen. Very odd indeed.
Reed diffusers are a huge trend in home fragrance—we can custom scent our diffuser oil with any of our wonderful perfume oils.
Some times low-tech is the best possible fix. Couldn't figure out a good way to diffuse the light from our high-powered LED tape. Then, on Labor Day weekend, we spotted some foam glow sticks in a display at the store. $5 and a pocket knife later we have success!
Currently, Robot Redux, our 2012 gallery show is in production! I hope you enjoy this tour of our Robot Factory!
This last prototype uses Carbon fiber strips like a dome tent, white ripstop nylon for the diffuser (and the inside surface), and black duck cloth. The connection is made with 12gauge aluminum armature wire
Now, before you try to figure out what you need to do in order to find the right aluminum for your projects, you must understand the importance aluminum extrusion profiles.
What is Aluminum Profile?
It is the process where the Aluminum alloy is transformed into specific cross-section profiles for various uses. The extrusion process brings the best physical characteristics of the alloy. In fact, the malleability is the flexible factor that allows the alloy to be machined easily. But you need to find the perfect company that is expert in aluminum extrusion profiles.
Aluminum extrusion is an innovative technology that helps in converting the aluminum alloy into multiple objects used for versatile purpose. It requires technology and equipments to undergo the whole process of extrusion. This helps in imparting unique physical characteristics to the alloy. It results in higher strength and durability.
