[QUOTE="Bob Blaylock, post: 385781, member: 16749"] I'm wondering about another line of claims that he makes… [indent][i]If you want to take these sort of photos today, you will [COLOR="#A9A9A9"]either[/COLOR] need [COLOR="#A9A9A9"]a high speed camera costing tens of thousands of dollars, or[/COLOR] a dangerous and expensive air gap flash. These use a high voltage spark to generate the short, bright flash needed. As they run at over 25,000 volts and need regular and dangerous electrode replacement, it's not surprising you can't buy them commercially.[/i][/indent] He repeats this claim a number of times, including this graphic, with the caption [i][B]“Top feature: it won't kill you!”[/B][/i]… [ATTACH=CONFIG]126663._xfImport[/ATTACH] Anyone know about, or have any experience with, these air gap flashes he mentions? They aren't really that dangerous, are they? I know that normal electronic flashes typically run at about five hundred volts, which would be plenty dangerous if there was enough current to back it, and an easy enough way to come in contact with it. I also know that it's possible to be exposed to static electricity in the millions of volts, with no ill effects. I'm not familiar with these kind of flashes, but I have a feeling that he is greatly exaggerating their danger, if not outright lying about it. [/QUOTE]
