| Re: Macro Photography Hi Bob
With regard to flash in macro photography I find it a great help when photographing insects, it helps freeze any movement resulting in a sharper photograph as well as lifting the detail a bit and eliminates unwanted shadows.
I use a standard flash unit rather than a ring flash. I have this mounted on an off camera flash bracket and put a lambency diffuser on the flash to spread and obviously diffuse the flash.
I use this set up as I can use the same flash unit for my bird photography which has saved me the expense of a dedicated macro ring flash.
The thing with flash for macro or any other photography for that matter is not over doing it. If you can tell the flash has been used then you have generally overdone it plus you will blow the highlights with too much flash anyway.
I'm not saying it's the way to go for you but it has worked very well for me and I'm happy with the results I get.
DOF is always a bit of an issue with macro photography but I don't find it too troublesome or restricting with the 150mm lens.
