I'm a Canon 600D just bought by my new mother, and I want to take a picture of my son. I bought a set of 135. Ask the experts to help me take photos with blurred background and prominent son.

The sensitivity of machines such as 600D to 3200 films is acceptable, but it is best not to exceed 1600. To take pictures of children indoors like you, it is best to set the metering mode to spot metering, focus on the center point (see the reference manual, which is easy to adjust), and then put the child's face in the center of the picture to shoot. Turn on one or two more lights in the darkroom at night, try not to use the flash, or shoot with the aperture first (open the aperture to the maximum, that is, the position with the smallest value). During the day, half the sensitivity is 100.

Background blur can be achieved by several methods, such as large aperture, long focal length and being as close as possible to the subject.
