Film not advancing fully

I noticed after developing negatives that my camera isn't advancing to the next frame of negative consistantly after a picture has been taken. Most frames end up overlapping. What is the cause of this problem and can it be fixed?

Re: Film not advancing fully

Are you sure that you have loaded the film properly?
Sometimes if you have not started the film so that the sprocket pulls the film correctly the film can aquire slack and the teeth of the sprocket may not be successfully pulling the film from the canister each time.

Why is film clear after developing? Using bulk load Tmaxx 400

Sounds like the camera isn't working. It would appear the shutter doesn't function because you have no images at all. I would open up the camera and check this. (Empty of film of course).

I took 4 rolls of film in for development but when I got them back all of them were either very under or overexposed despite taking all the pictures according to the light meter in the viewfinder of my...

Are you looking at the picture as in a print OR are you holding the negative up to the light and looking at it that way. Don't touch the negatives, they should be in a protective sleeve but you can see through it. You should be able to see if the spacing between the frames is messed up and if you have lighter and darker negatives. Looking at a print from an automated one hour service isn't worth the time of day to determine a problem. The Pentax K1000 is the work horse of the century for students learning photography and a lot of them have seen extensive use, also the camera is quite old. What I expect is if the negatives are showing overlapping frames AND the exposure is off sometimes over and other times underexposed then the camera needs service lubrication and adjustment. It's great that the light meter is working but the shutter speed could be off and the advance is skipping giving the overlap. I don't know where you are in this world but in Canada that's a $80.00 to $120.00 fix and have the repair person change the light seals while he/she has it apart.
The Pentax K1000 is still a great camera it's up to you whether or not to spend the money. I can't tell you what to do but I can suggest that if you are going to shoot film you find some place that does it with a little more human touch. Hope this was a help

Rewind my film by accident, how do I unrewind it?

If the film has retracted back into the cassette, you'll need to buy or borrow a film leader retriever to fish it out. The latter is a thin specially shaped piece of spring steel which is slipped into the cassette film slot in total darkness and then engages onto the film leader sprockets, enabling you to pull the film leader out again. They can be a little tricky to use if you haven't done so before. Then just load the film as usual and in total darkness (or with the lens cap on and the viewfinder fully covered) set the camera to 1/1000 shutter speed and the smallest aperture and fire and wind until you're one frame past where you left off to give you a safety margin against overlapping images.

Note that when you get the film processed you need to explain what's happened: if you don't and the negatives are automatically cut, the cutter may slice through the images taken after the film restarts. This is because the automated cutter looks at the first few frames to calibrate where to cut, and then continues this pattern for the entire roll. But the shots taken after the restart are unlikely to follow the exact same spacing. Cheap postal developing and printing companies cannot offer this tailored approach, but any good Mall/supermarket/High St minilab usually can although they may charge a little extra.

Basically, if you have to pay additional processing charges or have to buy a leader retriever, it may well be cheaper to develop and print the film as is and put the mistake down to experience.

I hope that I've assisted you and that you take a moment to rate my reply.

I have a problem. I have taken several rolls of film, after they are developed there is no pictures,just blank negatives,what might be the problem and how do I get it fixed?

If you can see the frame numbers on the edge of the unexposed negatives, the problem is most likely either the camera's shutter is not opening, or the camera's take-up/advance mechanism isn't working properly. It could also be that the film isn't being loaded correctly. Check all three, or have a camera shop (not department store!) check it out for you. They should be able to test the first two situations easily, and help you if it's a loading problem.

Pictures did not take-negatives were clear

It seems like a fault with the shuttter.  You will need to get it repaired.

Scratched negatives; broken tractor drive on two cameras

There doesn't seem to be a pattern with any of the Fuji films (I use Sensia and Velvia, exclusively, and have never had a problem in my Canon EOS). There are reports that the Fuji Pro films will gum up the sprockets in a camera, thanks to an adhesive strip at the end of the roll, but I'm not sure if the regular 400 speed film has the same problem. You might try a thorough cleaning, and see if it is still happening. I'm not surprised that 400 speed comes out a tad dark. Try dropping to 200 speed (I generally won't use anything above 100 speed, unless it is black&while).

Film developing clear


This problem could have a number of causes,

To check to see if it is a camera fault of developing fault you could try using a cheap colour film in the camera and getting it developed at a normal photo processor.
This will determine in which half of the process the fault lies.
If the pictures from the colour film are the same then it must be a camera usage problem or fault.
If the pictures are ok from the colour film then it will be a problem in either the film being used, developing problem (poor mix of chemicals etc).

This will just speed up the diagnosis a bit.

Film not loading properly

The lines could be scratches in the negatives.

Have you looked CLOSELY at your negatives with a magnifier to see if the scratches are on your film?

And when you say "Serviced", do you mean "cleaned" also?

If you have scratched film, then return it to the place you got it serviced/cleaned and let the owner/manager know that you just had it serviced there and it's scratching your negatives.

If you have an automatic camera, this bit below will be of no help.

Assuming that your camera is a manual loader, it may be that you aren't putting enough film into the take up spool for it to catch.

Try putting a little more film into the take up spool when you are loading the camera, and MAKE SURE that the holes in the film LINE UP with the film sprockets.

Then after you close the film door and start advancing your film, look at the film rewind knob, if it isn't turning while you are winding in film, then your film hasn't caught in the take up spool.

Another way to tell if your film is advancing is to shoot a test shot, and then advance the film, and then lightly turn the rewind knob a bit.

You should be able to feel the tension of the film if it is loaded correctly.

Negatives were in "widescreen"

The camera has a panoramic switch on it somwhere that caused a pair of baffles to close down over the film exposing only the center 1/2 of the film. The idea is that the print from this negative would be printed as a 4x11.5 inch photo. It's basically a 8x11.5 with the top and bottom of the print chopped off.
The only other alternative is that for some cameras had a panoramic adapter to place inside the film chamber, but that would be a very difficult thing to do inadvertantly.

My negatives are turning out clear.

"Clear" = no exposure, right? Two possibilities: light not getting in; or film not advancing. To check the former, take a "picture" with the camera open at the back. See the light through the lens? Yes = OK, No = there is a problem with the shutter. Most likely the film is not advancing. Here's a test. Load the camera with a roll of film and take one picture. Open the camera and see if film moved. If not, go read the manual to make sure you are loading it properly.
