What you describe is typical of a film which is getting scratched as it is used in the camera, either due to dirt or debris in the camera, a rough finish to a camera part in the film path, or even just a faulty film cassette which had a bit of grit in the light seal when the film was rewound. It's very common in cheaply made plastic toy cameras like Lomos and Holgas.

If it happens all the time, it's a camera fault. If it's intermittent it's either a camera fault or a processing lab fault, but most labs run regular test rolls through to ensure these faults do not occur. If it's a one-off, then it was probably a bit of debris in the film cassette light seal.

If the fault is in the camera, lay the negative across the back of the camera and then look and feel anywhere in the film path that the line appears along to find the problem. Rectification usually means a bit of cleaning, or smoothing down with a sharp knife or fine abrasive and be very careful not to allow the material you remove to fall into the camera and cause more problems.

My print outs are having lines across them

You need to have your printer go thru head cleaning cycle. Check to make sure the ink is not leaking from the cartridge. Are you using OEM ink or second hand?

are the lines slightly curved and go from the botom to top across the screen. If so it sounds like retrace lines from the CRTs being turned up too far. You can add the pic by clicking the camera Icon next to where it says Insert below the text box.

You have to use the "FILM AREA GUIDE" included with the scanner. This black plastic guide leaves a small area at the top of the glass open so that the scanner can calibrate itself at the start of each scan. Use the guide or leave at least 8mm between the top of your film and the top of the scanner glass.

I have a polaroid film 600 camera where can I get a battery for it, and how do I change it's battery?

The battery comes built in to the photo pack. All photo packs are now past their use by dates though as they have been out of production for more than a year, so any which you do find may have weak or flat batteries.

Photo packs which have been kept refrigerated will have better colour production and more accurate contrast but are far more likely to have flat batteries. Photo packs stored at around a constant twenty degrees Celsius are more likely to have a good battery, but there is a greater chance of poor photo colours & contrast and there is a greater chance that the photo ejection rollers will fail to squeeze the developing chemicals evenly across the photo.

The camera can be modified to take an external film pack, but it's a DIY job using whatever you have to hand; unfortunately I can't recall what the correct voltage is but if you ask another question on FixYa then someone will know.

35mm film developed with streaks

I take it the streak is a hot streak of light. If you're shooting negative, look at the negative and see if it's one long streak. If so the light leak could be anywhere between the film roll and the take up roll. I would open up the back, go into a closet and shine a bright light on the front of the camera and see if you can find the leak and tape it up. Otherwise, 35mm SLR's are very cheap these days. I'd recommend a Canon A-1 for your daughter, but you can't go wrong with any Canon or Nikon.

My developed color film from a Canon EOS has a notable thin line across the top which appears medium to dark-blue in all of my prints, especially those with blue sky tones. Is this a light leak? If so,...

Try to dust off the inside of the body, the mirror and ckeck if it is movin gorectly or if there's something in the way. Also it mai be "something scratching the negative from the front or the back, check your negative."

White streaks on photos

Light leak, definately a light leak. You need to change or add foam around the chamber to prevent any light from entering.
