Remember with TTL shooting, Brian, that your camera measures the light level before the actual shot so adding a diffuser tends to register as a darker scene; so if you aren't careful you end up 'chasing your own tail' with exposure compensation.
make that up to your standards.
Nice shot.
I think I missed something here. I don't understand this. I routinely use TTL with diffused flash, both in macro work and in doing candids of people (different forms of diffusion, obviously) and almost never need to use either EC or FEC with it. I think what happens is that the presence of diffusion is no different from greater distance--the preflash is registered as weaker, so the camera exposes more.
Brian,
This looks interesting. Danae Wolfe has a bunch of really nice macro shots using the reverse lens technique and her on-camera flash...

I wonder if this three dollar on-camera flash diffuser might not help you.

Here's anther...

This one would provide a really soft light source using your on-camera flash but, might just cut down the light too much. OTOH, your subject will probably be no more than a foot away from the flash...

I'm following this thread with great interest, not that I've ever used these small on-camera diffuser accessories.
I use A4 85gm tracing paper for benchtop work, with LED floodlights.
For a particular distance of lights from the subject - and by sliding the diffusing sheet back and forth between them, I can change the subject lighting from a true Lambertian surface (max diffusion) to approaching a point source (sheet hard up against the lamp).

The principle may be less easy to apply with a small diffuser on a camera-mounted flash, of course.
Strangely, in my perhaps saner moments I wonder if I really want to go down the path of artificial illumination. Flashes do open up the window of opportunity for shooting. But I really enjoy the challenges and restrictions of natural light. And an 18s. exposure on a Robber fly does give one a certain amount of bragging rights
Indeed, Brian. I rarely use flash for anything; the exception being for work-in-progress in the barn where it is mostly quite dark photography-wise.
As you may remember, I do have artificial lighting permanently setup on the bench, mainly for eBay sales and watches. In that situation, artificial lighting is definitely advantageous - now that I've learned to stop the seconds hand before shooting!
Your naturally-lit shots are quite admirable, I reckon.
