My PowerShot S30 has suddenly started to produce blue pictures

The manual says the following about colour cast:

1. Best results in most environments can normally be obtained with the [WB AUTO] setting, but for some subjects, you should try experimenting with different settings. (This is especially true for sunshade under a clear sky, mixed natural and artificial light settings, and so on.)
   

And although the WB settings are very limited I think this is the only option you have. Make sure you don't use to strong exposure compensation all the time.
The colour compensation you wish, are only found in high end cameras. Not even in all DSLR or system cameras.
If the colour cast is too strong, perhaps the manufacturer can help?

There's no way for the camera itself to cause this fault, so it's either due to the lighting, the wrong film, bad processing or out of date/badly stored film. Keeping the exposed film for a long while before sending it to be processed can also produce a strong colour cast.

I suggest that you upload sample photos to a website and then post a link to them. Also, please state what film you used and whether you have had the same problem from more than a single film. If so, were they all processed at the same time and place?

In the meantime, you may wish to re-check that your remaining unused film is still in date (use by/process by dates are normally printed on the outer carton) and that they've been kept away from high temperatures. You may also wish to contact the company which processed your film as they may very likely be at fault if they've made mistakes or failed to maintain their equipment and chemicals. Note that some processors now digitally scan and then print your negatives, so scanner or printer faults can also produce a strong colour cast.

Consider NOT connecting your camera to your computer.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive. Or you can use any photo cataloging program.

Never had that camera, however, had the same problem -- the pink stripe and pink cast. Turns out the lens cover was slightly cracked and not opening and closing properly. Thus -- the pink cast.

Most Compact cameras come with a software disk that has the photo software pre-loaded. My experience is that once you have loaded the software and uploaded your pictures, you can then convert the file to XP, or better still, to Photoshop.

Hope this helps

This isn't exactly a service manual, but something I had prepared for a friend who had a similar problem as you. Would recommend instead of fitting a new switch to replace the entier assembly. You can get broken S30's from ebay relatively cheap. Anyways, here's the file:

You probably have the White Balance set to a setting other a
than "Auto White Balance" (AWB). On the top of the camera, above the exterior LCD panel, there is the "AF-WB" button. Turn the camera on--past "on" to the bent line. Press the AF-WB button once. On the left side of the exterior LCD panel there is a vertical, reticular box with the symbol of the selected setting for WB. Normally, the setting should be set to AWB. If it is not, turn the command dial at the back of the camera until "AWB" is showing. Try shooting again-the color should be better.

In the "auto" modes (green box, portrait, landscape, etc) the AWB is automatically set. In the "advanced" modes (P,Tv, etc) the WB is manually set for whatever light source you are using. The command dial may have been accidently turned to different setting. Hope this helps.

Usually if you just plug the camera in it will mount as a removable disk (drive e: or similar) and you can move your files off to the hard drive.

Your PAL/NTSC settings must have changed. You'll find this in the camera menu somewhere.

Sorry if this sounds obvious, but this might rather have to do with White Balance. Rather than relying on AutoWhiteBalance, try setting it to "cloudy" or "shade", this may help the blue cast.
