How can i cause a light leak in a rangefinder?

Most naturally-occurring light leaks happen around the edges of the film door. Most cameras have black foam around the edge of the door to make a lightproof seal. Over time, the foam can degrade and let tiny amount of light in. You do not need much light to cause a significant leak.

I would suggest *not* doing anything to the camera (yet) but shoot a few rolls of film in it as it is. You'll probably like the effect you get from film using an old lens. If, after you've shot a few rolls you still want the light leak effect, I suggest scanning your negatives onto a computer and using Photoshop, GIMP, or some other image editor.

If you deliberately damage a nice camera, people on this forum will cry, and you'll probably regret the damage in the future.

I do not consider the challenge is you are cap. If it have been, the sunshine could come on always inspite of an entire tank. The EVAP (Gas evaporation process) attempts to maintain all gasoline fumes within the gasoline tank process. It screens for leaks at any time when you force through pressurizing the tank with a small quantity of air strain and seeing if it bleeds down. If it leaks off strain quick, it offers a code of a tremendous leak. If it takes much less time, it is a small leak. A lot of the minivans that yr had disorders with rubber hoses splitting inflicting leaks within the process. Look for a leak in a distinctive hose going back off the correct part of the van's inside finder just below the hood. You would possibly ought to consider it with you are hands. It's a plastic hose and wherein it splices to one more hose, the rubber connector is unhealthy approximately splitting. If this assessments OK, you may also ought to take it to a trader. They have expert techs. that use a smoke computer to discover the leak and to track the process to ensure it's constant after the fix. I cannot recollect what that yr's assurance had on EVAP approaches, however I consider it was once 10 years or one hundred,000 mile assurance. Check it out and notice.

Drop it a few times.
