Hi there,

today I saw this spiral with a drop of water on the end of it (didn't see the spider initially) but I used the MT24-EX macro twin lite flash and as you can see it showed up in the drop of water, will a diffuser stop this?

I realise the shots not a great one (still learning trying to master the to and fro of focusing)

But any tips on what I did wrong would be great.

Regards Darren

Exif info. 1/200sec, F/5.6, 100mm macro lens ISO-100, Manual mode. Flash set to 2:1 -1/3 compensation.

A very large diffuser (like 1 meter high) will reduce it, but it's difficult to eliminate with on-camera flash.

So adding a diffuser to the flash won't do enough?

It might help a little, you'll get larger highlights that aren't quite so bright.

Water has a very reflective surface. It will easily reflect any light source onto your image. Changing the size and/or position of the light source in this instance would merely change the size and/or position of the reflection.

I'm not aware of "diffusers" available for macro flash units. Are there any?

You could try tissue and rubberbands for a diffuser

Curtis is right, because the drop of water is a very curved reflective surface you'll get a reflection with just about anything. You could create a light box around it. You need a large enough diffused light that the reflection is evenly distributed across the drop and doesn't create a hot spot.

ARe you able to move this type of flash off camera? You could always have the flash to the side so that the angle of reflection was not visible from the camera??
