I have a range of DIY softboxes which I use for macro photography. In each case the light from the flash is first spread onto a surface which then lights the subject with a much softer light than with the bare flash.
My First Softbox

My first softbox was a fairly simple cardboard arrangement which I still use when I’m at home taking macro shots at a magnification of 1:1 or less. For information on how I made it, see: I made a softbox for my flash
My Collapsible Softbox

I next made a collapsible version of my first softbox which easily fits into my camera bag meaning I can take it with me on walks, etc. I use it under the same conditions as the first one – with magnification of 1:1 and less. See: Collapsible softbox
High Magnification Softbox

As I started using extension tubes, I found the larger softboxes were too large and I was not getting enough light to stop down and increase depth of field. This box is quite compact and so can be easily carried in my camera pack. I use this with extension tubes when magnification is greater than 1:1.
Long Focal Length Softbox

When I got my 200mm macro lens in January, I found that the existing softboxes were too far from the subject and not giving me enough light. I made a new collapsible softbox which extends the light surface to in front of the lens.

Very ingenious. Thanks for taking the time to write them up for us! I wish I was this creative with my equipment
Andrew Trevor-...:
No problem, Steve. Maybe I’m just cheap. ;)

Blow me away… you are so kind to share this information! Well done!!

Glad to be of service.

Andrew, thanks for this. For several months I’ve been suffering the photographic equivalent of writer’s block. I made a box out of cardboard & tissue paper with the intention of putting small objects inside, lighting from outside & playing with my macro attachment. Perhaps now I’ll do it! Your JE could just be the spur I so greatly need.
I shall read your links later, many thanks again.

You’re welcome, Jesika. My first one took less than an hour to make. I was surprised just how easy it was.

Thanks so much Andrew, I was just thinking about how I was going to make my own (there’s no maybe – I’m definitely cheap!) 8-)
Andrew Trevor-...:
You are welcome, Tarnya. They are as easy to use as they are to make.

Thank you so much for sharing this. I have big problems with this using my Nikon and have tried several solutions, none of which really work that well.
Andrew Trevor-...:
You’re welcome, Byron. Perhaps make a prototype first and see how that works for you.
