My Panasonic Lumix DMC FZ7 digital camera has started saving all pictures in both JPEG and TIFF formats, which is a pain because it takes up a great deal of space. As I've lost the manual, it is proving impossible to fix this. Can you help? Name and address supplied DQ: I have always felt very uncomfortable saying something is the best, the first or the fastest. But I feel a special case can be made for Steve's Digicams ( www.steves-digicam.com ). It is a terrific site for anyone who wants to learn about digital cameras. He has more information than you could ever want about all the latest gadgets. His reviews are extremely thorough with lots of pictures. If you are thinking of buying a digital camera, you could do a lot worse than to see what this site has to say. The site's comments are aimed at the experienced photographer or, at least, the very patient. Beyond reviewing and displaying results from new cameras, this site keeps records of older ones too. Your particular camera - long since upgraded, of course - and its many recording modes can be found at www.steves-digicams.com/2006_reviews/fz7_pg3.html . If you scroll down the page, you should come across Record Menu options and under that there will be 'Picture', 'Size' and 'Quality'. You can set the size to 'small' or the quality to 'JPEG'. One of those ought to fix your problem. If that fails, you can go to Panasonic on the Web and they will sell you a manual. You might imagine they'd be free, but they're not. I have just bought a MacBook Pro computer and want to connect an external monitor with the notebook's top closed. But every time I close it, the machine goes to sleep. Is there any way to prevent this? Tommy C, Mui Wo DQ: You're in luck; today nearly all Macs come with Bluetooth, the ubiquitous short-range wireless link you need. You must have a Bluetooth-enabled keyboard or mouse so you can connect the two devices. You'll then need to set up your Mac so a Bluetooth device is allowed to wake up the computer. The sequence you work in is important. You must make certain that Bluetooth is turned on (look in System Preferences);'pair' your device - keyboard or mouse - with your machine; in System Preferences, make sure the Bluetooth device is allowed to wake the machine; then plug the monitor into the MacBook Pro. You should see your desktop on the external monitor. When it appears, you can close the lid and wake up the machine with your external keyboard or mouse. Check out http://docs.info.apple.com/article.html?artnum=300562 , where Apple suggests that process for an older machine. It should also work for your MacBook Pro.
