A few weeks ago, I discovered a really cool app for the iPhone that lets you do long-exposures during day-time without any filters - well, kind of...
The app is called AvgCameraPro and is available for $0.99 in the iTunes App store.
Here is what you need and how it works:
- A tripod or some kind of stabilization for the iPhone is a must.
I use the predecessor of the Joby GripTight GorillaPod for the iPhone and either place it on the ground or bend its arms around the ballhead of my Gitzo tripod.
- The app will take multiple pictures (1-128) and blends them together to create that long-exposure effect.
I pretty much always choose 128 pictures and I wish it would let me shoot even more than that. The 128 picture setting will shoot a picture every ~1.5 seconds so the approximate "exposure time" is at around 3 minutes. In order to get really nice smooth clouds on a not too windy day, a 5-6 minutes exposure would work best.
- You can actually see the picture evolve as it blends the individual frames in real-time while shooting - this is really cool
- The drawback is that the app shoots the pictures with only 2 Megapixels so you end up with a 1224x1632 pixel image - this is not so cool...
