[langtitle=es]Falta sincronizacion flash pentax kx[/langtitle]

Tengo una pentax kx la cual no he podido usar en la noche porque no dispara el flash. Y si lo hace, primero dispara un preflash y luego nada.
He intentado cambiando baterias, asi como tambien utilizando la velocidad 1/180 que es la que supuestamente sincroniza el flash. A veces toma fotos bien y otras salen oscuras. HE probado flash manual y sucede lo mismo. Por otro lado, he tratado de subir unas fotos para que me ayuden y no he podido... quisiera me ayudaran en mi problema.
Gracias

I assume that you use an autofocus lens and that you're talking about the built-in flash. I don't have a K-x, but the pre-flash is probably the focus assist. And if it can't acquire focus, you can't take a picture (using default settings). So the first question would be if you indeed get the green hexagon under those conditions?

To test, you can set the camera MF and take some photos; it does not really have to be in focus, just to check if the flash reliably fires when you press the shutter fully.

With regards to incorrect exposure; read the camera's manual with regards to the relationship between flash distance, aperture and guide number. Which mode are you using? Av, P, ... Which ISO setting?

And for the upload; you should basically tell us what goes wrong. But in short one of the ways to do it
1)
resize the photo in your favourite image viewer/editor to something like 900x600 and save it with a new name (e.g. IMGP0000_resized.jpg)
2)
When you start a thread or post a reply (don't use quick reply for this), there is an option to manage attachments (just below the submit and preview buttons). Use that to attach a file to the post.
