Flash for Macro

Here are a few of my current insect photos taken at night, tFFhey often find in thick scrub with uncertain foothold. As can be seen, the lighting (and focus) could be better, these also strange colour hues easily seen on the Bristletail, although many rarely stay still long enough for multiple photos. Using a flash with diffuse should help even out the lighting.
