The most probable issue here would be that your glimmer isn’t incredible enough to sufficiently light up the subject at the separation you’re taking shots at – so essentially draw a couple of feet nearer if conceivable, as opposed to zooming in which won’t make the blaze any more remarkable.
Flash, albeit totally accommodating in most low light situations, has a restricted range all things considered, and the blaze on board your camera will be more vulnerable than a real embellishment flashgun.
So putting resources into a greater and better frill streak (if your camera takes into consideration such a connection) is another undeniable arrangement.
