Let's face it, the camera on the iPhone is pretty poor but just because you wouldn't really want to use it to take photos doesn't mean that the iPhone is useless for photography. Thanks to the PhotoBuddy App, the iPhone is actually an incredibly useful photographic tool. Why? Because PhotoBuddy lets you work out Depth of Field Calculations, Flash Calculations, Exposure Calculations, Calculate Sunrise & Sunset Times and Phases of the Moon and a whole lot more.
Back in March 2007 I wrote this article where I compared the RAW processing of Photoshop, Lightroom 1.0, Aperture 1.5 and Capture One 3.7. The results of that test was that Aperture produced the best results but that overall Capture One was the best RAW editor. The disadvantage of Capture One of course is the fact that it has no file management capabilities which led to the conclusion that, if you had a Mac, Aperture was the best choice if you needed file management as well as RAW processing.
If you own a Digital SLR at some point you will look at your photos and wonder why there are little black spots in the same position on some of them. Often people think that it's a mark either on or inside their lenses - which it's possible it could be but if you have multiple lenses it's very easy to rule this out, whilst I've even heard of some people thinking that the sensor on their camera has been damaged and have sent it off for repair.
In 99% of these cases the cause of these black marks is simply dust on the sensor. Even if you don't currently have any marks on your photos there is still a very good chance that you have dust on your sensor too. To see if you have try this simple test.
