senior ed was kind enough to point out that my p/k1000 needs to be synced to my flash. Anybody know how to do this, or why my flash would be out of sync at speed of 1/60 or higher? thanx

You don't need to do anything, except to set the shutter speed at a speed low enough to work with an electronic flash. The reason the flash doesn't synchronize with the shutter at higher speeds is not a matter of adjustment. It has to do with the way the shutter works.
The focal plane shutter in your camera consists basically of two curtains, sort of like roller blinds. At lower speeds, one curtain opens, and after a suitable time, the second one follows after it and closes. There is a point when the entire shutter is open at once. An electronic flash, which has a very short duration, can be fired during that time, and it will work.
However, at higher speeds, instead of opening one curtain, then closing the other, the shutter works by separating the curtains slightly, to form a slit, and passing that slit across the film. There is no point at which the entire shutter area is open, so the short burst of an electronic flash cannot hit the whole film. Once upon a time, special long-burning flashbulbs were made which could work at higher shutter speeds, but they are a thing of the past.
To make better sense of this, next time you're between rolls of film, open the back of the camera, and look through it as you operate the shutter at different speeds. You will easily see the difference between slow and fast speeds. |

The K1000 flash sync speed is 1/60 of a sec. It will not sync at higher speeds.
If it is not giving you good flash pictures at 1/60, then you have a shutter problem. |
