In the third photo, we can see two people, a man and a woman, having a coffee in what seems to be a cafe. The table takes up much of the foreground, and the people are positioned towards the back of the image. Because the entire image is in focus, the aperture of the camera must be pretty small. That means that the camera doesn't let in a lot of light. Because of this, the shutter must be opened for longer in order to get an image, explaining why the subjects are blurred out.
CRITIQUE: What was the artist's intention? I think that by blurring out the subjects, it makes it seem like they've been there for a while, which gives a sense of time to the image. By keeping the rest of the photo still, it shows the stillness of the objects, contrasting the constant movement of the people.
The sense of movement is my favourite part about this photo. It really adds personality and meaning to the image. I also like the low contrast, as it makes it seem more realistic and lifelike.
Overall, since the image is in focus and is visually interesting, I would say that it's a successful pinhole photograph.
