With what can i cover a polaroid flash

the batt are built into the film

You certainly have a vivid imagination. I think the technical term is 'broken' - repair would be economically unviable.

Polaroid 600 film cameras only have a single battery, built into the film packs. To remove the film pack, open the door on the door and grip the sides of the pack and slide it out.

Unfortunately, most Polaroid cameras were not really built to be repaired. They're mostly all plastic with no way to get into them to repair anything aside from rollers, without destroying the camera. And, with Polaroid going bankrupt several years back, parts are now nonexistent anywhere but the 2nd hand market. The good news, these cameras can be had on ebay and other sources for under $10, so I'd just buy a new one.

It's probably more an issue of how/where that one image was taken in relation to the others than it is an issue of the physical condition of that one photo.

Different lighting conditions can fool the in-camera light meter and cause a photo that is either too light or too dark, and this is probably that happened. Or, sometimes someone doesn't notice and their hand/finger is over the electric eye. Generally if an image is "bad", it'll be dark or non-existant on Polaroid cameras, because of the process they use.

How old is the film in it?

Polaroid film packs have a battery included (a polarpulse powercell, I think).

If its an old film, the battery can go flat and as far as I'm aware there's no way to get power in to it.

I would take the cartridge out, (effectively not use the last shot), try a new cartridge to see if its working properly, then send the old cartridge back to Polaroid, if you think its faulty.

These cameras have the battery built in to the instant photo cartridge; every time a new cartridge is loaded the camera therefore gets a fresh battery as well.

Stored in cool, dry conditions the cameras will last a very long while. I've owned one since 1978 and last used it around 1983 but when I ran a film pack through it last year it worked perfectly.

The only thing which may cause a problem is if the grease on internal moving parts dries out, but there aren't many such parts, just a motor and very simple photo eject mechanism. Not like the myriad of tiny precision parts in a regular film camera which may jam under such circumstances.

In short, the most of the remaining Polaroid cameras should long outlast the availability of the instant photo packs which are no longer in production and which do not stay fresh forever.

Regarding the issue of "the light is not on when i open it" you'll need to state which exact model you're referring to and which light. The only one which I'm aware of was the flash ready light on the later models which had a built in flash forming part of the camera lens cover.

If the camera is showing no signs of life at all then you probably have an old stock photo pack loaded into it. These have the camera battery built in to them and like all batteries have a finite shelf life.

If you have a voltmeter then remove the photo pack and measure the voltage on the electrical contact points on the underside, if it's below a steady 6v then the battery is dead. If not the camera is dead and you can pick replacements up for less than the cost of a photo pack from thrift/charity shops and there's plenty of free ones available on Yahoo FreeCycle

On a Polaroid 600 you won't find one: the 6v battery is built into the photo pack, so every time you load a photo pack you get a new battery.

Beware of old stock photo packs though unless they're *very* cheap; there's a significant risk that they won't be usable due to a dead battery.

Scratch4:

unfortunately i do not keep those dino's.
from memory:
some models will flash automatically,
some models will flash if the light is lifted up
some models have a switch and you should be able to find it if you look around carefully.

but my advice is, trash it as i suggested to other poster.
because you are spending good money after bad, and because

1). the DC prices are so cheap and you can get remarkable crispy sharp "instant" pictures than the "blurr" polariod's.
2). the polaroid films are so expensive and difficult to find, and usually they are not fresh anymore on the shelves, if you are lucky to find them.
3). the films only match certain models, not all
4). the battery built-in the film pack may go low (i have been working for a company which was its battery mftr).
