All good advice but a lot of older flashes have trigger voltages over 100v. I have several that have a trigger voltage of 200v+. Most newer flashes will have a low trigger voltage.

Or you can make your own if you are that way inclined.




These are the basic components required




& this is one I made earlier, built into a hotshoe adapter.







I have also built this circuit into an old Vivtar 273 which had a trigger voltage of 327v! It is now safe at 6v. Couple of images here >>>>>>>> link

Denture tablets work great, I have used them on a few flash brollys & they come out spotless! Fill your bath with warm water, add a few tablets & watch the grime vanish!. Milton fluid is also very good.

At the same time as Uranus had it's pronunciation altered

I had one of these a couple of years ago but gave it away. As I remember it works very simply. Set switch on front to Auto then set aperture to match ISO scale on rear ISO 100 - f5.6, 200 - f8, 400 - f11 or set switch to Manual & check scale on rear to select correct aperture ie: at ISO 100 with flash to subject distance of 2 feet set aperture to f8 (this is from memory so check scale on your flash!!)

Hope this helps.

Adobe have online help. Sounds like you need to create link to images from thumbnails & this is explained in the help.
