Here’s a neat GoPro feature that you might not know about: the GoPro actually has a setting where you can take video and still photos simultaneously. No, we’re not talking about pulling low-res stills out of video. We mean actually snapping high-res stills at an interval while shooting video. Read more…

Almost all of us know him. In fact, he was probably our first friend at some point. His name? Tom Anderson — more affectionately referred to as Myspace Tom. As a co-founder of one of the first giants of social networking, Myspace, Anderson has had a hefty pile of cash to play around with since 2005 when he sold Myspace to News Corp. for $580 million.
Have you ever noticed that the watches and clocks found in product photographs and advertisements usually show the time 10:10? If you haven’t, pay attention the next time you’re flipping through a publication and come across a watch ad—the rule is almost always true.
If you have noticed this, do you know why 10:10 is the default time for watch photographers?
Here’s an interesting photo trivia question: can you name any major world currencies that feature an image of a camera?
Answer: the old five hundred peso bill over in the Philippines. On the back of the original series is an image of a Rolleiflex twin-lens reflex camera!
Did you know that some of the most famous master painters from centuries past may have actually used camera “technology” to aid them in creating their masterpieces? According to the hotly debated Hockney-Falco thesis, some well-known artists likely used rudimentary camera obscura rooms as a tool — essentially “tracing” parts of their work.
Do you ever clean the front element of your lens by fogging it up with your breath and then wiping it off with a cloth? If so, you might want to stop — Nikon says the practice could be damaging to your glass. Apparently human breath contains stuff that isn’t too friendly toward camera lenses.
This is probably a “duh” fact for many of you, but one that some of you have perhaps never heard or realized before: Did you know that the flashes in the Canon Speedlite lineup are named after their maximum guide numbers? To figure out the power of your Speedlite, just take the model name and hack off the zero at the end to get the GN (e.g. 430EX has GN 43, 580EX has GN 58).
If you’ve visited the CN Tower in Toronto, Canada anytime during the past five years at night, you’ve likely enjoyed the dazzling light show that appears on the side of the tower. The 1,330 uber-bright LED lights (which cost a cool $2.5 million) were installed in the elevator shafts back in 2007, and are turned on from dusk every day until 2 the next morning. What you might not have known, however, is that the seemingly random colors that appear are really not so random after all: they’re actually pieces of photographs!
Photographer Jeff Cable purchased a couple Canon 5D Mark IIIs recently and discovered that although the camera offers both SD and CF card slots, you should avoid the SD slot if you want maximum shooting speed. He writes,
[...] for some reason unbeknownst to me, Canon decided to build the 5D Mark III with one very fast CF slot which supports the newer UDMA7 protocol and a standard SD card slot which does NOT support the high speed standard [...] Without UHS [Ultra High Speed] support, the top speed that can be achieved by the SD card is 133x. This is true even if you purchase a 600x SD card and insert it in the camera. The best you will get is 133x
It turns out that the camera will default to the slowest card inserted. So, if you have a 1000x CF card in slot one and any SD card in the second slot, the very best buffer clear that will achieve is 133x.
It might not be a big deal for most photographers, but if your line of work requires clearing the camera’s buffer as quickly as possible, it something you might want to be aware of.

Take a look at your camera, and there’s a good chance it’ll have this symbol: Φ — a small circle bisected by a long line that looks like a hieroglyph of Saturn. If you’ve always wondered what it means, today’s your lucky day: it’s called a “film plane mark” (or “focal plane mark”, depending on who you ask), and indicates exactly where the film (or sensor) plane is inside the camera body. One reason the mark is useful is that macro photographers often want to determine the exact distance between their subject and the film plane, and the mark can make this calculation much easier.
