D90 “ERR” mystery solved

I was having intermittent trouble with my new D90 recently. The dreaded blinking “ERR” in the LCD. My symptoms included: wouldn’t focus, shutter would trip but no image recorded, ERR light. The only way to clear it was to remove the battery. The thing is that it would only happen once in a while so, at first, I didn’t think too much about it. It got bad enough though that I decided I had a bad copy and was about to send it back for a replacement when… I noticed that the LCD would flickr when I wiggled the lens.

The solution? I removed the lens, wiped down the contacts and the mounting ring, and reattached it. Problem solved. I feel a little sheepish admitting how lame/lazy I am for not checking that in the first place. Lessons learned? I’m an idiot. Plus, check the lens mount if you’re getting weird intermittent mechanical problems with your DSLR.

Photosynth

I’ve recently come across Photosynth, I had heard of it about a year ago when it was still in its tech preview phase and then I’d forgotten about it. Which I shouldn’t have done because it really is cool. Microsoft Live Labs, who own Photosynth, call it “an entirely new visual medium.” And they’re pretty much right, it’s a very cool new way of viewing photographs. Basically it works by analyzing a set of photos and using the data to build a model of the subject, then it re-creates the environment and uses it as a canvas for the photo. Which doesn’t sound as awesome as it is so head over to Photosynth where you can play about with creating and viewing synths yourself.

National Geographic is creating synths of global landmarks like Macchu Pichu, Stonehenge, and the Pantheon which you can view on the National Geographic Magazine webiste. The BBC also has a gallery called “The Future of Photography” on their website which has collections of synths built on locations from the BBC One series “How We Built Britain”, including Trafalgar Square, Ely Cathedral, and the Scottish Parliament Building.

Oh, but there is a downside; this being a Microsoft project you’ll need Windows XP or Vista for Photosyth to work…(sigh)

What would you like me to review next?

Ok, it’s official, I’m drowning in photography book reviews. I will get to all of these in the coming weeks but since I’ve got such a stack of them I thought I’d ask you… which of these books would you like to see reviewed first? And if you can spare the brain cells, what about a second choice?

The books, in no particular order:

Actually, exclude Practical HDRI because I think I’ve had that one the longest so I’ll review it next. But after that? Let me know what you’d like to see next.
