Looking good Preston

Thanks John. Mucking about with equipment and stuff is lots of fun.

I also have a Brian/LordV diffuser but had trouble forming the connection to the flash. To resolve this I made a sleeve from foam board to wrap around the flash head and then taped the can formation to the foam board. Makes it real easy to get on /off the flash also made the formation of the diffuser a bit easier as you have a firm pre-shaped surface to tape it too

Im trying to figure out the best Flash bracket for me. Im exreamly handy and will be able to adapt my idea's to a bracket of choice.

What I dont get is after I attach the flash bracket how will I be able to put a shoe on for my tripod?

Not sure if it's the best way of doing it but you can get the male 1/4" camera attachment bolt things with a female thread on the back of them so you can attach via another male 1/4" (presumably the shoe has this).

Still under construction, made from parts I found at work. Brian, how did you make the diffuser on yours?

Like it- bet the bugs put their hands in the air when they see that pointed at them - what mag ? - I reckon that lot does just over 10:1

OMG, you people have some insane rigs here for Macro shooting. I had no idea of such setups. Awesome job to all.

Brian, I figured 12:1 or so..

first I made a typo on the extension tubes, it should be 12/20/36

so theres 68mm, add that to the 100mm macro, you got 168mm, and ~1.68:1
(I'm told that every 1mm you add in bellows/extensions it adds .01 magnification)

times that by 2 (for the 2x extender) you get 336mm divide that by 28mm and you get 12 even. All I know is grains of salt are pretty big. I just got these extension tubes today, so I haven't shot anything really.

I'm not sure what formula to follow

(Main Lens + Extensions) x (extension power) / rev. lens

Adam I'd just photograph the mm scale of a ruler then mag = sensor width/mm across pic. The calculations have some flaws in them esp where extension tubes are concerned. Somewhere between 10 and 12:1 anyway

Brian V.

Heres with the full setup, only thing I did was Re-size, no sharpening :]

I'll get around to photographing a ruler one of these days, I'll post it here

Shots @ F/16

Adam,

Wow! great job.

Thomas

Heres the MM on a ruler.
shot with 20D
No adjustments, only resize.

Reckon that is only just over 7:1 ? -- 22.5/3.2

I only haw my dads old yashice external flash. Can anyone please suggest what can I use to defuse light?



Thanks.

from the bench..............

WOW
And I thought my rigs looked crazy.

My main set up is a ringflash but I also use a FL 50 and a softbox2 on a boom as well as a smaller flash on a cord.

Ringflash on my 330 along with the my helper. (very cheap, worked for crickets)

I use a flashlight and cheap close-up lenses...sometimes the on-camera flash dialed way down

seems to work for me

Here's my redneck dual Bud Light beer can snoot setup (original single snoot design by LordV and he gave me permission to publish this):







No Flash, P-Mode:

I plan to make a more robust paper towel diffuser on the main snoot this weekend.

Here's a link to more images and my youtube build video.

2X - 6X setup with focusing light & flash diffuser.............

Well, I came across this link in the Lighting forum: DIY Ring Flash So I decided to make my own. I didn't follow his instructions to the "T" but the result is just about the same. Diagram and BOM here: Parts List

Sorry about the volume of images, but it should help explain the "cause and effect".

I'm going to add my Foam ring flash while this is up.
