High Speed Video Created With Still Photographs
Recording high speed video can be prohibitively expensive — especially at a decent resolution. It's not uncommon for the price of a quality high-speed video camera to reach into six figure territory. YouTuber Smarter Every Day, however, hacked his normal SLR to make a slow-motion shot of bullets flying through the air and smashing through matches.
So, how did he do it? With a very precisely timed flash and camera synchronization. They clamped a gun in place, and fired tens of shots at a specific target. For each shot, the flash and camera fired a little bit later in the process. These images were then stitched together to create a slow motion effect, as the bullet moves through the air. Yup, it's just like stop-motion animation, but using objects actually moving rather than carefully placed and positioned.
The shooting rig was a Canon T1i, lit with a 580 EXII strobe, set to 1/128th power setting, and the shots were taken at 50 microseconds incriments.
Unfortunately, it's not something you can easily do at home, as they used a very, very high end piece of technology to make sure the timing was perfect — a Quantum Composer Pulse Generator 9520 . It's still a very cool example, though.
Canon 580 Flash - News
To do these photos, I shot at 1/800th and at F/8 with the Canon 580 EX II set to 1/4 power output with a Sto-fen Omnibounce on the flash head. Then what I did was I placed the flash above and camera-left. This was all done with the camera being held
With the Canon 5D Mk II, 7D, and even the 1D Mk IV, this lens had loads of focusing problems in low light but nearly always hit its mark in areas that are well lit. Using a flash like the 580 EX II to aid in focusing using the infrared beams still
though, you'll see that the results are absolutely worth it. It also helps to know what you're doing with manual flash usage because the Ray Flash wasn't playing so nicely with Canon's E-TTL system when mounted on the 580 EX II.

#1: COMPARE PRICE CANON SPEEDLITE | Canon Speedlite 580EX Flash ...
Disappointed with large room/high ceiling picture results with my Canon 420EX speedlight (see my review) mounted on my Canon dRebel - sent me shopping about 6 months ago for more light (you can never have enough light). My E-TTL flash metering with the 420EX also proved uneven - with sometimes unexpected over exposures and blown highlights. A solution for both was found!
The 580EX appears to get me an additional TWO F-Stops and much better metering (E-TTL2) on my new Canon D20. Less time in Photoshop with better exposures, fewer blown highlights and the fantastic multi-shot strobe function are paying dividends with every indoor photoshoot I cover. It is worth the price for people who use the camera for a living - or are serious "pro-sumer" phototographers.
I've since purchased a Canon D20 camera - paired it with my 580EX and am EXTREMELY happy with the result. The two items are made for each other. As happy as I am with my 300D (dRebel) and overall happy with my 420EX (see my review) the 580EX has allowed me to take my photography to the next level.
I carry 3 sets (4AA) of 2500 amp/hr Ni-Mh rechargables good for over 100-150 (or more) shots per battery charge. I "fast recharge" two sets while using the other. I'm investigating a battery pack - but have not yet justified the expense - as the Ni-Mn rechargable prices continue to tumble.
Using my dRebel, I shoot portraits with a battery grip from Canon (BGE1-see my review) and a speedlight flip bracket from Stroboframe (see review) and the Canon hotshoe off camera shoe cord (see my review). The lighter weight of the 580EX than the older 550EX which I nixed - allows me longer shoots with less hand fatigue and better camera balance. Be aware it is still larger and heavier than the smaller 420EX and is not for everyone.
The 580EX is a Canon "Master" speedlight - allowing my 420EX life extension as a very dependable "slave" unit with very positive results on my portrait and event work.
Is it worth the price?
Yes - if:
1. You can never have enough light 3. Don't need the performance and features (which are twice the cost of the 420EX).
Canon products are well made, well engineered, dependable and fairly priced. All my major purchases of cameras, lenses, speedlights and printers have all been good performers over time.
With that said, the battery door gives me the same occasional latching problem that my 420EX exhibits (rolling batteries around on the floor in front of a client is NOT a pretty sight -- I know - I shouldn't be in such a hurry...
My 580 ex I I flash just fell 6 feet off my stand and hit the concrete. Operator error and everthing still works.
