I don't think I have your humble disposition, Tom, I much prefer it when I can blame my shortcomings on someone or something else!

My milk packet and your Armorall dispenser are certain to solve all of our problems!

Well here it is, made with one Armorall wipes dispenser, some velcro, one medium rubber band ( from a bunch of brocolli )and a piece of an old white tee shirt. The result, one ugly but functional macro flash difuser. I am going to raid my wifes knee high supply to try different shades, white , toupe, red, and black just to see what the affect will be. But that will have to wait until the weekend.

Extend the lens out to 1:1 and see how it works there. I think that set up would be better if the diffusor wasn't squared, but at an angle like 45 degrees. Whatever it takes to put the beam just in front of the lens. And take some test shots of something with some dimension to it, so you can see how hard or soft the shadows are.

Great stuff Tom. What external flash is that?
I guess you could make the "extension" a bit longer and angle down a bit so it's closer to the front of the lens if you find out the shadows get too harsh or long if you do a test like stiuskr suggested.

Btw: Why do all the desks we do this work at look so similar, mine is a lighter shade of "wood", but the sticky's and other clutter is exactly the same

Turerkan did a version of this before :)

My diffuser was made with a hole in the bottom with a sort of flap so I can use it with my Bower flash or the on-board flash, whichever I like. I've done a test run on both and found the on-board to be a little weak for some situations, but the Bower is too powerful in close even at -2 EV and -2 flash - need to have a second diffuser layer on hand I think. This is where my skills with a needle may come in handy, will make one like a sort of shower cap to just stick on the end.
The new litre milk packets are ready made with a tilt on one side - perfect for this!

Looks good Liz!
Try making the cloth doubled on the end to absorb some of the light from the flash or try some different shades. Different color knee high stockings might work, or a difuser mounted directly on the flash plus the extention carton. Now the hard / fun part begins, finding the correct combo!! Thank God for digital!! I would have gone broke long ago if I was still shooting film.
If I have time , I will do some more test shots with my creation this afternoon.

Thanks Tom!
Tweaking EV among other things at various distances from the subject helped quite a lot, but a white butterfly that posed for me had to be done flashless. I'm uploading some of my trial shots to my gallery now, but here's one that was taken with the diffuser.

Hi Pieter,
Sorry I took so long to respond, my wife broke her ankle two weeks ago and I have been doing double duty around the house plus taking care of her.
Thanks for the compliment.
The flash is a Sony HVL-F36AM, I still have to play around to make it a little softer, it tends to over expose but I will get it sooner or later.
I hear what you are saying about the desk! I cleaned it a month ago and it took me three weeks to find everything I put away!!   
Hope you had an enjoyable birthday.

Great tips on home made diffusers and great lens. Im lucky I found an MFC-1000 to connect my old 1200AF to as well as a 2400twin flash head, which really makes macro so much easier.

But before owning a macro flash I did the same thing, use an external flash and DIFFUSE BY ANY MEAN POSSIBLE, so that I could use the high Fstops needed with my Sigma105mmF2.8 to increase DOF and not suffer blowouts.

Also, when taking photos of any highly reflective objects a fancy macro flash such as the MFC-1000 wont help much, until you DIFFUSE LIKE CRAZY... .

For subjects that are not likely to run away, I still use a couple Min5600HS flashes with an adapter I made to which I can attach an umbrella reflector/diffuser to more evenly light the subject and trigger them wirelessly.

1. Old pocket watch lit with two diffused Min5600HS flashes using a Sigma105mmF2.8


If I get time I will post a couple later macros and the setup I used.

@thomcher144: I have to start experimenting with my 3600 flash and macro. Sofar only used the onboard flash, but if you diffuse it isn't really powerfull enough to get smaller than f 5.6 or f8. Had a splendid birthday, spent most of the day outside in our garden with all the visitors. Much less clean-up work afterwards
Hope your wife is doing better. It's pretty bad to be immobalized and for the rest feel well.

@wolfy: very nice lighting, "soft" but distinct and single shadows (with 2 flashes) of the hands. Well done. Be interesting to see your set-up. There's still so much I need to learn about macro and flash.

Pieter & Moises,
Thank you for the well wishes for my wife. She is basicly bored, not in any pain, just uncomfortable, she can't get around very well. The crutches have proved to be quite a challange for her.
Thanks again,
