Photography:Digital Camera Troubleshooting Guide

The following is a set of useful tips for troubleshooting your digital camera and/or an external flash unit you may have attached to it. First, look for the title which best describes the problem, then follow the steps below it...

POOR BUT RECOGNIZABLE PICTURE QUALITY

1. The batteries may need replacement. Some digital cameras continue to function when their battery power is low, but produce grainy photos with incorrect coloration. Make sure you aren't using Ni-Cd rechargeable batteries, which are generally not recommended for cameras.
2. For the best picture quality, make sure the camera is set to its highest resolution. This may have been adjusted by accident. The process for doing this varies greatly among different digital cameras. Keep in mind that fewer photos will fit in the camera's memory and it will probably take longer to transfer them to the computer, at a higher resolution.
3. Digital photography tends to be more prone to blurring (caused by slight movement of the camera while the photo is taken) than 35mm film, especially with very small or lightweight digital cameras. To remedy this, try using a tripod and/or the camera's timer, if it has one. Adjust the camera's shutter speed if possible.
4. If colors are too pale, using an image editing/viewing program (such as PictureWorks MediaCenter) to increase the Saturation level may be helpful. If the camera has produced colors which are entirely wrong (everything is in shades of black and purple, for example), you can turn the saturation all the way down so that it becomes a black & white photo.
5. The lens may need cleaning. Make sure you use a cleaning material which will not scratch the lens. If possible, refer to its manual for specific cleaning instructions.

CAMERA WILL NOT TRANSMIT IMAGES TO THE COMPUTER

1. Make sure the data transfer cable is securely connected to the computer and camera.
2. If the serial cable was connected to the computer while it was on, you may need to shut it down and turn it back on again. This does not apply to USB cables.
3. If you have the choice to use a serial cable or a USB cable, try switching to the cable type you haven't already tried. For example, I have an older digital camera which can use a USB cable in Windows 98, but only works with a serial cable in Windows XP.
4. Make sure the camera's auto power-off feature didn't turn it off before you tried to start downloading the photos. Most digital cameras will not activate this feature if they are connected with a USB cable, but some will when using a serial cable.
5. If possible, try using the digital camera with a different computer and/or a different camera with the same computer, to help determine which piece of equipment is problem's source.

THE CAMERA WILL NOT POWER ON AND/OR DOESN'T RESPOND

1. If it is attached to the computer with a cable, detach it and try turning it on again.
2. Try powering it through a USB cable or an AC adapter, if it has one. If this works, it probably needs new batteries, unless the battery compartment is corroded.
3. Replace the batteries. Try to avoid this if it has photos stored on it and is a camera which loses them when the batteries are removed. If the batteries were recently replaced, make sure they were inserted in the proper direction.
4. If the temperature is very hot or cold, try it in an area with a more normal temperature.
5. Some digital cameras have a feature which automatically turns them off after a second if the batteries are low. This allows them to retain enough power to store the photos and transfer them to the computer when necessary.

PHOTOS ARE SCRAMBLED OR AREN'T STORED ON THE CAMERA

1. On some digital cameras, photos currently stored on the camera may become scrambled or have multi-colored streaks across them if the batteries are replaced before they are downloaded.
2. Check the camera's LCD before taking each photo to make sure it has not run out of memory or activated its auto power-off feature.
3. Turn the camera off, power it on again, and try transferring the photographs again.

THE CAMERA'S EXTERNAL FLASH UNIT DOES NOT FIRE
1. Make sure the flash unit is correctly seated in the flash port (a.k.a. "hot shoe") or its sync cable is securely plugged into both the flash unit and the digital camera. Confirm that none of its settings have been accidentally adjusted (it might not fire if it is in "auto" or "computer" mode and it determines there is already enough lighting) and the batteries are fresh.
2. Press the flash unit's test button. Most flash units have one of these on back of them, below the other controls; it is usually a clear or red-colored button, occasionally having the "Ready" light built into it. If the flash fires, it is more likely to be a problem with the camera or the connection between the camera and flash.
3. Try testing the flash unit on a different camera to help determine the source of the problem. Basic 35mm cameras with "hot shoe" flash ports can be purchased rather inexpensively at eBay.com, thrift stores, and some yard sales. Some expensive model- or brand-specific flash units will not fit on these cameras, however.

If none of these steps solve the problem, there are a number of potential problems with the camera and/or computer which could be causing it; some possibilities include that the computer's serial or USB port card may not be properly installed, the camera driver or software might be incorrectly configured, the camera could be damaged, or the computer's operating system may be incompatible with the camera. While the problem could be expensive to fix, on the other hand it might still be as simple as changing a setting on the computer or camera. It is probably best to contact the digital camera manufacturer's technical support; check the camera itself, its instruction manual, the manufacturer's website, or the camera's original package for a telephone number.
