Here's a video on light positioning. The down side is that it's kind of a primer, and the rest of the series is behind a paywall. In addition it's geared toward cinematography. But the concepts apply to photography just the same. The way that you use light will do more to define your photographic style than anything else...

I wish that the other 3 videos were not behind a pay wall, but it was still good just on it's own.

This video illustrates the principles that motivate why I tell begginers to lighting to simply get one or two halogen desk lamps and

  • play with positioning
  • play with relative intensity


...and SEE what one or both can do to flatter a face or to make it into at ghoulish mask
-- before buying ANY photographic artificial light, particularly speedlights which give the photographer ZERO idea of what the placement does to the subject appearance (use of speedlight merely 'illuminates', it does not 'light')

Just noticed this thread about diffusers for macro. It is good to keep discussing this topic. John is right about the difficulty of quantifying diffused light.

Also, in my search for the ideal diffuser for macro, I have found that one diffuser does not fit all. Ideally, you would want a different diffuser for a shiny bug (for instance a beetle) compared to a bug with a dull appearance (moth). The degree of magnification also affects how light from a particular diffuser looks.

But when we are in the field, there is usually little to no opportunity to tailor the lighting rig for the subject. At least that is my experience. I load the rig up with my flash and modifier and shoot what I find. That means (for me) that there will be variance in the results.

But I accept the compromise. Where I live, we have bugs for only about 4 months of the year, mid-May to mid-September. Therefore much of my bug photography takes place on trips to warmer places. And that imposes another compromise: the gear has to be portable for travel. My solution, as mentioned in other threads, has been to use a fan-shaped diffuser on the end of my 100mm L with a snoot on a camera-mounted flash. The materials collapse flat and weigh practically nothing. They give satisfactory results at times IMO.

Here are a couple of examples from my last trip, which was to Cuba.

Lygaeus sp bug, looks OK to me.

Excellent point, and that's why I said in the beginning that this wouldn't be a discussion of what the best light source is, because it's too situational. The best light source is the one that lets you get the shot that you want, and often the subject dictates what you're going to use.
