My DIY macro flash diffuser, which is simply a plastic plate with a semicircle cut out, attached to the lens hood of my Tamron 90 macro.
Led flash diffuser. This diffuser will be built Into the LED flash module. I have a gap of 38mm stamped for the Mitutoyo lens.

Update:
Softball is a 12 inch type, not 9 inch as market on the picture!
You need to view the largest size to see this comparison. Series of single shots taken with and without diffusers at two different apertures. the shots are near 100% crops of photos taken at 3:1 magnification.
Diffuser 1 is 3 layers of styrofoam wrap - light loss approx 1 stop.
Diffuser 2 is a back projection material, light loss approx 2 stops.
Both applied to one of my coke can frames.
The main point being the difference between using a diffuser and not. The diffuser helps remove specular highlights in the hairs but with a reduction in contrast over the image which affects how detail is seen.
I ran across the tutorial here, but it’s just a cigarette pack with the foil facing inside. And some plastic stapled to the front so the light diffuses higher and a little better. Also it works infinitely better if the flash faces you and you bounce it off a ceiling or something.
I’m actually pretty sure it would hold up reasonably well under more practical shooting situations. You know, the kind with people in. Except it looks like some hobo taped shit onto my camera so that’s a little embarrassing.
Yeah a Speedlite would be cool, but this cost me 4¢.
29-year-old female with untreated hyperthyroidism, goiter, and dysphagia. The gross thyroidectomy specimen weighed 132 g.
Quick add-on diffuser - part of a plastic disposable dish clipped onto the end of the MPE-65.
The diffuser worked well but tended to scare off bugs before I could shoot them.

A diffuser hack for a Omnibounce/Lambency type of lighting.
Made on Christmas Eve after taking a bunch of bounced-flash pictures of the family. Inspiration came from all the other diffuser/baretube hacks that have been floating around the 'net for the last few years.
It's a high-density polyethylene (PE-HD) bottle which used to hold lactose and was left over from one of the kids' medical treatments. Luckily the hole was cut accurately enough that it grips the flash body without needing extra tape, bands or velcro.
The female Evarcha species on a flash diffuser.
This female Jumping Spider, an Evarcha species, was found in a similar place to the male Evarcha falcata. However, looking it up later it didn't seem be consistent with a female Evarcha falcata, but more like E.arcuata. Although there is one feature missing, and that is the dark cardiac stripe. It looks like a not completely mature specimen.
Any second opinions on the species are welcome as E.arcuata has not been found on this site/area before. I'll be searching for another individual now to confirm the species.
Diffuse - The Dictionary of Image.
I am really pleased with how this has turned out. I took this image in a quiet moment at work. I was mixing up some agar mixed with indicator fluid, for an experiment with various molarities of acids. I noticed that the indicator fluid turned the nutrient agar mixture this bright green (acid then turns it pink) and thought it looked really interesting. Then I shook the McCartney bottles up to mix them, before autoclaving them, and thought this then looked even better.
The idea to add the definition of diffuse came to me in a sudden flash of inspiration, when I saw one of my contacts Dictionary of Image submissions, defining 'separation'. I just thought that this worked alongside it nicely.
The text was added with the Gimp, and the font is Andalus.
The definition is from the on-line dictionary service, dictionary.com.

Immersed in absolute alcohol, the cut surface of this specimen demonstrates the follicular architecture very nicely. Choose the "Original" size to really see the detail.

My DIY macro flash diffuser, which is simply a plastic plate with a semicircle cut out, attached to the lens hood of my Tamron 90 macro.
My dad purchased this for me, since I don't have a flash and have to use the onboard one when it's too dark and I'm taking pictures of kids. (They don't like to sit still.) Before he got this for me I was using a piece of wax paper over the flash. Believe it or not, this works better.
Shots taken at 1:1 with my 5Dmk2/MPE-65/430 Ex flash setup.
Top no diffuser
middle my standard coke can diffuser with 1 layer of LCD diffuser + 1 layer kitchen towel. This gives 2 stops light loss compared to no diffuser.
Bottom as the middle but with a layer of LCD dispersion film directly on the flash head. This film gives a 0.2 stops light loss but does give slight but noticeable reduction in contrast. The film when used the right way round has the interesting property of splitting a single light beam into two separate beams.
I obtained both the LCD diffuser and dispersion films from an old portable PC LCD screen I took apart.

I've been cutting up plastic milk containers to make flash diffusers - the Gary Fong looks great but seems expensive for a bit of plastic. I wanted to throw some diffused light forward and also get plenty of widely diffused light from the ceiling as well. I marked up a 3 litre and 2 litre bottle as shown in the picture, then cut round the line to make a kind of clamshell shape, with a tail that will slip through a couple of rubber bands on the flash head.
The picture shows the fixing.
I rotate the upright flash head through 90 degrees, so that when the camera is used vertical, the head can just be folded up to the new position.
I have a Gary Fong CloudSphere diffuser. After looking into macro photography I saw online how to make your own Coke can diffuser (By Lord V) that works well for Macro Photography. I am using it with a Bellows, Canon EX550, Canon 30D ISO 200 and shutter speed 200, Flast set to ettl. I am still playing however it seems to work well. I still need a real Macro lens however my expearimentation has been fun.
Here's the Lord V thread.
