In her comment on my picture 'Let's Dance' our fellow 500px member Jane Sleeth posted that she had no idea what my home-made orangejuice flashtube was. This is not the first time I got that question so here we go:
First of all, the 'problem' or rather 'challange' with my macro's is, in my opinion, the available light. Typical I want a small aperture of f/11 and above, even better is f/16. Together with that small aperture I want a low ISO rating to get the most out of my pictures. With my macro lens, a 90mm, I need at least a shutter speed of 1/125 to avoid shaken images, eventhough I have set my 'SR' on in my K-x body.
So summed up that's:
Do the maths, I need a lot of light!
The typical insect macro-lens is, imho, at least 90mm and has a aperture of f/2.8. That means a long lens, and that means that if I use my built-in flash, the light of the flash does not reach the object that's in front of my lens. So it's pretty useless...
I need to get that light onto my subject so I can achieve my optimal settings stated above! How do I do that? Quite simple of course, I can buy a professional macro-flash ring! That would work absolutely fabulous, but it's also very expensive. Instead of that I made, and let me say that it's not my own idea, a macro-flash from scratch.
Buy some orange juice or another type of juice you find good to drink and drink it! Then get out your scissors or stanley-knife and make it snug-fit to tour camera and macro-lens. To make the light more diffuse and somewhat tempered you can use packing material like I used but you can also use a tissue, toiletpaper, etc. The rubber band is to keep it on my camera when maneuvering it around.
Build your own and tweak your settings when shooting, you'll soon find it very easy to work with! Click on 'read more' to see some more pictures.
