Look at the two photographs.

a color photo of a passenger train.

a black and white photo of a freight train.

how are these two images different from each other? check all that apply.

the use of color
the use of a human subject
the use of artificial and natural light
the use of trains as subjects
the use of movement to depict mood

The correct answers are the following:

1. The use of color

2. The use of a human subject

3. The use of artificial and natural light

Explanation:

Just by putting the two images in comparison it is easy to detect their differences.

The most obvious one would be the use of color: only one of the images have color, the other one is in black and white.

The use of a human subject is another easy one to spot: in one of the pictures there are humans, in the other you cannot see any humans.

The last one, about the use of artificial and natural light, might be the trickiest one to detect if you're not paying too much attention. In the colored picture, it is night time, and therefore the only light sources are from the train lights and the station light (no natural light, aka the sun). On the contrary, the black and white photo is taken during the day, and therefore it is illuminated by natural lighting.
