After a 9 days in Costa Rica, I'm finally able to start processing the 1700 or so photos from the trip, I can finally show you some results of using the GFE on real-world subjects, like Howler Monkeys and birds.

Though the cardboard construction barely managed to hold up after being carried around in my camera bag, some quick repairs with tape got it back into working order. The most use that it got was on the 7th day, when we visited the Curu Wildlife Refuge near the town of Tambor on the Nicoya Peninsula.
This dry tropical forest is thriving with birds of all types, lizards and three species of monkeys: the White-faced (capuchin) Monkey, the Howler Monkey and the Spider Monkey. After spending 3 hours walking through canopied forest, the GFE was in constant play.
These examples are a few of showing what kind of difference the GFE made when using my 420EX flash with my 10D and a 70-200mm F4L lens. The lens was usually at 200mm or close to it to bring in the subjects that were high in the tree cover above.

| The above results are a little skewed due to using Aperture Priority mode, but the up-lit foliage is obiously better). | |

One thing to note, these are shots taken without the flash and with the flash+GFE. Due to the hassle of actually removing the GFE from the 420EX, I did not take comperative photos of the wildlife with just the 420EX itself. However, for subjects over 100 feet away, I'm confident the GFE did make an improvement over just the use of a 420EX alone.
