Take pictures with fill flash I took a picture of my baby in a garden, but the picture is full of shadows, I read that I can use my flash like a fill flash, to reduce the shadows, but my question is, what is the speed?, if I use 1/125 and my flash what is the aperture?. I have a Minolta with a lens 50mm. Thanks Jorge.

It depends on what kind of camera and flash you are using. Which model of Minolta camera are you using (manual or automatic)? What brand and model of your flash? Some manual cameras, or even older automatic cameras, has maximum sync speed of 1/60 to 1/90. Some flashes has the light output controlled by the camera (TTL). Some has a sensor on itself and some just do full burst (the aperture will then be depended on the subject distance). So if you give us some information of your equipment, we can help you more. Hope this helps.

Thank you for your answer, the model of my camera is Minolta x370n the speed is the 1 to 1000, the flash is vivitar V2000, and I was thinking to use a pola filter to improve the color, film 100 ISO, what do you think?

Just do a search and found out that your camera's top sync speed is 1/60 second and the Vivitar v2000 flash is a manual flash with a guide number of 79ft at ISO 100 that does not sync with your camera. That's mean that you have to set your aperture based on the subject distance (and the shutter speed on your camera has to set at 1/60 or slower). To find out what aperture to use, you have to divide the guide number by the subject distance. For example, if you are 10 feet away from the subject, then the aperture will be f8 because 79 / 10 ~= 8. Remember if you are using higher ISO film, e.g. ISO 200 film, then your f stop will be f11 because the film is one time faster and you have to close down the aperture one stop. If you are 15 feet away, the aperture will be f5.6 because 79 / 15 ~= 5.3. You can get the distance to subject from your lens' distance scale, if any. Hope this helps.
