Why are the photos I took not as bright as others?

According to your composition and exposure, playing with the camera should not last long. If the photo you posted is in jpg format, then the color temperature was not set when you took it, at least it was warm (girls' clothes were red and yellow, and chrysanthemums were yellow and red). We usually play the film in raw format, and then adjust the color temperature later. White clouds in the sky and white walls of buildings have been exposed.

There is a white feeling about photos, and there is. According to the blur degree of the photo background, the aperture is set smaller when shooting. In the first gear (aperture priority mode), the smaller the aperture, the slower the shutter, the more light the shutter enters, and the brighter the photo, which is one of the reasons for the white feeling. Another reason is the shooting time. According to the reflectivity of the photo, shooting should be in the time period of 10- 15, and the light in this time period is the most difficult in a day.

Another reason is that there is no later adjustment and modification. If you are a producer of raw film, it is recommended to use NX2 for simple post-adjustment, so as to reduce the color temperature and pull the color scale, fully reflect the high light and low light, and give the photos a sense of depth. In this way, the white feeling will be relieved or disappeared to a certain extent. When the sense of white disappears, the photos become transparent and the colors look good. If you don't feel enough, you can add a little color saturation.

I hope the above suggestions are useful to you. If it helps, please adopt it.
