Nic Sadler and Toby Evetts of Chemical Wedding are already quite well know because of their amazing iPhone sun position calculator, Helios. I’m planning on covering the app very soon… but it may have to wait a bit. Why? Because these guys are about to release what may be one the niftiest filmmaking apps yet. It’s called Artemis (the Director’s Viewfinder). I’ll let them explain. It’s currently under review at Apple, and should be hitting the app store in a week or two.

Shooting video with the iPhone 3Gs typically yields some pretty shaky results. That’s why you might want to consider adding an iPhone grip to your equipment list. There are two grips that have crossed my radar in recent days: The OWLe (which is just now entering production), and Zacuto’s ZGrip. Fortunately, Zacuto had a booth at the expo, so I was able to get my hands on the ZGrip Jr. and Pro. They both felt solid, and very well made. Both improved the stability of my shots, though not by a enormous amount (it’s still an iPhone, after all). Mandy Rogers and Jens Bogehegn from Zacuto were kind enough to give us the nickel tour. Sorry about the less-than-perfect picture and sound quality.

What can you do if your perfect production is made a little less perfect by some lousy audio? Very often, an actor’s lines will be unusable because of extra noise, background sounds, or a variety of technical glitches. But, don’t despair. You can easy replace that bad dialogue with the help of your iPhone, and we’re going to show you how. This tutorial also demonstrates the use of the FourTrack recording app, and an external mic named Mikey.
