Stephen,
All the kit being used here. ....... Do I see another new toy.
A really good idea using the monopod as a light stand. The picture is a good example of flash fall off without using black flags. Exposure is spot on as I can see the pattern in the egg shells.
I notice you used the 28 - 70 and ended up at 52mm. Also f13 ..... seen that number before ..... thats what I set when I use the Multiblitz at a similar distance. Nice soft light through the Lastolite. So now you have the equivalent of my big softbox for a lot less.
