We'll be heading out for some night photography next month. Playing with long exposures is one of the thing you can't get around. Especially since I don't have any f/0.2 lenses in my bag.
Most lenses are sharpest (the so-called sweet-spot) around 2 stops from their biggest aperture (mostly around the apertures of f/8 and f/11) , but the problem is that these apertures kill the available light hitting the sensor of your camera. You could turn up the ISO (to 102400 if you have a Nikon D3s), but that gives you noise, and lots of it with most consumer dSLR's.
The only proper thing to do is adjusting the shutterspeed. Leave the aperture on its sweet-spot (f/9 or f/11), and the ISO at ISO100 or ISO200 (for the lowest amount of noise). But if you do that, chances are that you need exposures much longer than the available maximum on your camera, which is 15 or 30 seconds (depending on your camera). Which leaves you with the bulb setting on your camera. But how do you calculate the time needed for an exposure?
Bulb means that the shutter stays open for as long as you press the shutter release button.
In the post before this one I had some trouble with a Freecom XXS USB drive. I had no way of fixing it, so it went back to the store (and basically back to Freecom). But since that drive is used for offsite backups I needed a replacement unit, because the return of the old drive could take several weeks.
This time the Western Digital My Passport Essentials 500GB (2.5" USB powered) disk was chosen. A nice small device with lot's of storage capacity.
Western Digital Proprietary Connector on the LeftUpon opening the box I noticed immediately that there's something 'wrong' with this drive. The cable / USB connector is proprietary. The connector is some sort of ultra-mini-USB format. No need to say that of all the USB cables I collected over the years will ever fit. So I need to be extremely careful with the one I got with the drive.
Since I lose stuff (hell, everyone does), you could expect a blog post of me swearing 'bloody hell' (and stuff) when I have lost the cable.... but I won't, just read the rest of this review.
Before I go into the imperfections of the iPhone, I must mention that the iPhone is one of the best (smart)phones I've had so far.....My (smartphone) references are the Nokia Communicator, Nokia E61i, Nokia N95. While the PDA experience comes from Psion (to bad that they are gone), and a boatload of crappy/unstable Windows CE/Mobile platforms over the last 10 years.
Every device had its limitations, but the iPhone clearly has the upperhand (at the moment). But there's always room for improvement :-)
