The F90x is like many other automatic winding SLR's in that it winds film back into the cassette as the film is exposed rather than by pulling the film out (which then has to be manually rewound back into the cassette after the final exposure).

So if the developed films are coming back totally blank (i.e. clear, apart from pre-imprinted information such as frame numbers and film edge markings) it can only mean that the film has not been exposed. This will happen if the film was not initially wound out of the cassette at all or if the shutter mechanism is not exposing the film. In the first instance, there will be a blackened frame or two at the start of the film after the initial darkened film leader, where the same frame has been exposed repeatedly. But if this fault occurs then it also shows up as the film does not get wound back into the cassette with each new exposure. I therefore strongly suspect that the shutter assembly is faulty and it's not an uncommon fault.

The official fix is to replace the shutter assembly, but it's not cheap to buy and labour is also expensive and on some models the parts can be difficult to obtain (I haven't repaired an F90 for a while, so don't know one way or the other). In reality, repair costs far outweigh the cost of the camera so it's better to consign the F90 to be cannibalised for spare parts and to obtain a suitable replacement model.

Both autofocus and earlier manual focus Nikons can be easily obtained for free or peanuts on FreeCycle/Freegle or on auction websites.

What type of film is best for the canon elan 7e, I just purchased this camera and it is my first real 35mm camera, I want nice pictures but don't want to pay out the nose for film, what is the best type of...


The first thing to decide is what sort of pictures do you want to end up with; black and white prints, colour prints, or colour transparencies. Then, in what format do you want to keep them; in negatives in storage, in digital format, or as prints in an album or book. If b/w and as prints, the best film to start with is Ilford either FP4 medium speed or HP5 higher speed. If colour print then Fuji or Kodak 100 ASA film. To get started really cheaply there are loads of these types of films available on ebay listed under Lomography, mostly out of date films, but they will work fine to get you started. Keep in the fridge as soon as you get them, but let them warm up before you load or shoot them. Supermarkets will develop only colour C41 process. I think a few will still scan to CD for you. If not buy a negative scanner, then you can print your own without a darkroom. For fine grain go to slower film speed (50 ASA), for higher speed you will get more grain.
Best thing of all is to process b/w yourself. Anything else just email me david@dtmpower.com Bye

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 don't know how to buy film for this camera. is it just 35mm 400 film


Yes, you can get 35mm in color negative or black and white. Although the black and white film may be in 2 varieties: traditional process black and white(not all labs can process this) and C-41 process black and white (and one hour lab can process this). If you are looking for color film choose the C-41 color negative film like Kodak gold 400 or Fujicolor 400.

How do you load film into a Leica111a


Leica IIIc was made for many years. the bottom of the camera comes off by twisting the flip style finger shackle. The film take up spool must be removed to attach the film to it. pull the film out at the same whidth of the camera and insert. It seems like a tetious task although owning a Leica makes it well worth it

Film won't load on Minolta 400si Maxxum Camera


My daughter took the camera to her photography teacher he was able to load the film by wrapping more film around the roller. It's not as easy to load as my Canon. I thought we had put plenty of film around it already. Oh well, it's working anyway.

Film developing clear


Hello

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.

Minolta X370 film loading problem.


 First make sure your batteries are OK , camera will not work without two 1.5 v batteries. If your camera still doesnt work this is probably  because the shutter is cocked but you cannot release the shutter and that is why you cannot advance the transport mechanism. The shutter release mechanism needs repairing first. SREMEDY : take bottom cover off ( 4 screws ) and locate 220 mf 6v capacitor ( it is the only one in this part of the camera , cant miss it ). Replace the capacitor while you keep an eye on the polarity ( indicated on the casing of the capacitor ) and you camera should work fine ( dont forget camera needs  two 1.5v  batteries to work ! )
