Quick camera question.

I have a newish Canon Rebel XS that I've been using to learn how shoot in a manual mode (I was a click-and-shoot girl before.) Over the weekend, I played a bit with shutter speed, trying out long exposures with a slow shutter speed, trying out manual focus, etc. No problems with the camera at all. Then this morning, I can't shoot anything at all. When I press the shutter, it 1) does not focus despite the fact I have the button back on automatic focus, and 2) the shutter makes these weird... um, shuttery sounds, 2-3 times, without depressing all the way down or taking a picture.

I think this is something obvious that I should be able to fix, but damned if I can figure out what.

Bluetooth headset question:

Because I value the Buffista opinion...

I have an iPhone and right now I'm using the little earbuds that came with it. But I want something Bluetooth and comfortable for the long phone conversations I have in the car. Any recommendations?

I'm not sure if this is truly tech or not . . .

I have a new Nook, and I have a txt-to-pdf conversion utility. However, when I have the file on Medium font size, the words will split in the middle at the screen edge instead of between words. Is this a failure of the PDF format or of a cheap converter utility? If I set the file to Small size (unreadable) I see a lovely block of text with the lines ending at the line breaks.

I'll be happy if I can just get the lines to break between words.

Does the txt-to-pdf utility let you change the dimensions of the page? Maybe you can set the page to the size of the Nook screen, instead of 8½ × 11.

What it does is set up a virtual PDF printer. That's a good idea about the page size. Off to experiment!

Nonian, I don't know if this will work for you, but I picked up a little gadget for $4.99 at CVS that plugs into the headphone jack and the phone then runs through the car radio.

Are you trying to turn text into PDF for reading on the Nook? If so you might try using Calibre. It can create EPubs which I think will probably work better.

Nonian, I love my Jawbone Icon. It's in my ear for at least an hour each way on my commute. It tells you exactly how much talk time is left and can connect to more than one device at a time. also does a fabulous job of screening out background noise, including wind. It The only drawback is the relatively short talk time (about 4 hours), but that's never been an issue for me yet. It uses a standard micro USB charger so I hook it up to my car phone charger and it's ready to go for the ride home.

That seems like a way better idea.
